Latest Pocket Android app makes it easier to discover your saved and new stories

Mozilla Blog - ti, 24/01/2023 - 17:02

Google recently named Pocket as one of the best apps of 2022, and it’s only getting better. We spent a lot of time with our users last year to see how we can improve the experience on the Pocket Android app. This month, we’re rolling out updates based on user feedback so you can easily find the stories and topics you care about. Read on to learn more about what’s new in the Pocket Android app. 

Home is where you can find the joy of high-quality recommendations

We can all agree that a home is where we can take a deep breath, relax and unwind. So, we’ve created a new tab called Home where you can take the time to sit back, discover, and enjoy fascinating stories you want to read. There, you’ll see your recent saves at the top of the screen and discover new content from editorial recommendations or specific categories like technology, travel and entertainment. In the coming year, we’ll be adding new features to Home so that you can continue to discover and save high quality content. 

Home has your recent saves and new content from editorial recommendations Finding your recent saves just got easier 

As requested by Pocket users, we’ve renamed My List to Saves, where you can see the content you’ve saved to read at a more convenient time. We’ve also redesigned the section to let you filter by tags, favorites and highlights, as well as allow you to easily bulk edit. We moved filters into a carousel at the top of the page. Plus, we added a toggle for users to archive content. Lastly, we added the text “Listen” to the Listen icon. Together, these small changes can make a big impact in helping users get to their saved content quickly. 

Redesigned Saves section lets you easily see the content you’ve saved What’s ahead for 2023

We’ve done a lot of work on the Pocket Android app to evolve and improve your experience. This work lays down the foundation where we will continue to build more features. Many of today’s features will be available in the upcoming iOS app refresh launching this year. 

Discover the best of the web by downloading the latest Pocket Android app on Google Play.

Real talk: Did your 5-year-old just tease you about having too many open tabs?

No one ever wanted to say “tech-savvy toddler” but here we are. It’s not like you just walked into the kitchen one morning and your kid was sucking on a binky and editing Wikipedia, right? Wait, really? It was pretty close to that? Well, for years there’s been an ongoing conversation on internet usage in families’ lives, and in 2020, the pandemic made us come face-to-face with that elephant in the room, the internet. There was no way around it. We went online for everything from virtual classrooms for kids, playing video games with friends, conducting video meetings with co-workers, and of course, streaming movies and TV shows. The internet’s role in our lives became a more permanent fixture in our family. It’s about time we gave it a rethink.

We conducted a survey with YouGov to get an understanding of how families use the internet in the United States, Canada, France, Germany and the United Kingdom. In November, we shared a preview with top insights from the report which included:

  • Many parents believe their kids have no idea how to protect themselves online. About one in three parents in France and Germany don’t think their child “has any idea on how to protect themselves or their information online.” In the U.S., Canada and the U.K., about a quarter of parents feel the same way.
  • U.S. parents spend the most time online compared to parents in other countries, and so do their children. Survey takers in the U.S. reported an average of seven hours of daily internet use via web browsers, mobile apps and other means. Asked how many hours their children spend online on a typical day, U.S. parents said an average of four hours. That’s compared to two hours of internet use among children in France, where parents reported spending about five hours online everyday. No matter where a child grows up, they spend more time online a day as they get older. 
  • Yes, toddlers use the web. Parents in North America and Western Europe reported introducing their kids to the internet some time between two and eight years old.  North America and the U.K. skew younger, with kids first getting introduced online between two and five for about a third of households.  Kids are introduced to the internet in France and Germany when they are older, between eight to 14 years old.

Today, we’re sharing more of the report, as well as our insights of what the numbers are telling us. Below is a link to the report:

 The Tech Talk Toddlers, tablets, and the ‘Tech Talk’ Download our report

The internet is a great place for families. It gives us new opportunities to discover the world, connect with others and just generally make our lives easier and more colorful. But it also comes with new challenges and complications for the people raising the next generations. Mozilla wants to help families make the best online decisions, whatever that looks like, with our latest series, The Tech Talk.

Here’s what’s going on in the world of extensions

Mozilla Blog - ti, 17/01/2023 - 15:05
Credit: Nick Velazquez

About one-third of Firefox users have installed an add-on before – whether it’s an extension to add powerful and customizable features or a visual theme to personalize the web browsing experience. But if you’re unfamiliar, add-ons are sort of like apps for your browser. They can add all kinds of features to Firefox to make browsing faster, safer or just more fun.

The past year introduced some exciting new changes to the extensions world. The majority of these changes are foundational and take place in the deeply technical back-end of the system, typically out of sight of most Firefox users. However, if you pride yourself on hanging out in popular cybersecurity hubs, reading the latest tech news or developing your own extensions then you might have caught wind of some of these changes yourself.

If you’re not in the loop about the new changes in extensions, let us break it down for you!

Several years ago, Google proposed Manifest V3 (aka a number of intrinsic changes to the Chrome extension framework). Many of these changes would introduce incompatibilities between Firefox and Chromium-based browsers. This means developers would need to support two very different versions of their extensions if they wanted them available for both Firefox and Chromium-based browser users – a heavy burden for most developers that could result in some extensions only being available for one browser.

We believe that Firefox users benefit most when they have access to the broadest selection of useful extensions and features available, thus we’ve always placed long-term bets on cross-browser compatibility and a standards-driven feature for extensions.

With that, we agreed to introduce Manifest V3 support for add-ons, maintaining a high level of compatibility to support cross-browser development. However, there are some critical areas — like security and privacy — where our principles call for a different course of action. In a few targeted areas we decided to depart from Chrome’s implementation and incorporate our own distinctively Mozilla elements. Thus Firefox’s version of Manifest V3 will provide cross-browser extension interoperability, along with uniquely improved privacy and security safeguards, and enhanced compatibility for mobile extensions.

If ads give you the ick, then one distinction we’ve made around ad blockers has been especially crucial to privacy-lovers everywhere.

Content blockers are super important to privacy-minded Firefox users and tend to be the most popular type of browser extension. They not only prevent ick-inducing ads from following you around the internet, but they also make browsing faster and more seamless.

So we weren’t surprised to hear that Chrome users were concerned after learning that several of the internet’s most popular ad blockers, like uBlock Origin, would lose some of their privacy-preserving functionality on Google’s web browser, resulting from the changes Manifest V3 brings to Chrome’s extensions platform – changes that strengthen other facets of security, while unfortunately limiting the capabilities of certain types of privacy extensions.

But rest assured that in spite of these changes to Chrome’s new extensions architecture, Firefox’s implementation of Manifest V3 ensures users can access the most effective privacy tools available like uBlock Origin and other content-blocking and privacy-preserving extensions.

The new extensions button on Firefox gives users control

Adopting Manifest V3 also paved the way for a handy new addition to your Firefox browser toolbar: the extensions button. This gives users the ability to inspect and control which extensions have permission to access specific websites you visit.

The majority of extensions need access to user data on websites in order to work, which allows extensions to offer powerful features and cater to a variety of user needs. Regrettably, this level of site access can be misused and jeopardize user privacy. The extensions button essentially provides users with an opt-in capability and choice that didn’t exist before.

The panel shows the user’s installed and enabled extensions and their current permissions. Users are free to grant ongoing access to a website or to make that decision per visit and can remove, report, and manage extensions and their permissions directly from the toolbar. 

And if you’re not seeing those controls for a beloved extension of yours, it’s most likely because it’s not yet available in its Manifest V3 version. Don’t fret! Changes take time.

We love choice, especially when tied to enhancing user privacy and security – a double-win!

At Mozilla, we’re all about protecting your privacy and security – all while offering add-ons and features that enhance performance and functionality so you can experience the very best of the web. If interested, you can find more information about the extensions button at

And if you’re a longtime Chrome user, don’t sweat it! Exploring a safer and more private alternative doesn’t have to be challenging. We can help you make the switch from Chrome to Firefox as your desktop browser in five simple steps. And don’t worry, you can bring along your bookmarks, saved passwords and even browsing history with you!

Mozilla Thunderbird: Help Keep Thunderbird Alive and Thriving In 2023

Mozilla planet - ti, 22/11/2022 - 17:35

Roc, the Thunderbird mascot

A few short years ago Thunderbird was on the verge of extinction. But you saved us! This year we began work on an Android version of Thunderbird, made excellent progress toward next year’s “Supernova” release, and hired more talented software engineers, developers, and designers to help us make Thunderbird better than ever in 2023.

Putting YOU In Control — Not A Corporation

Since 2003, part of our mission has been giving you a customizable communication experience full of powerful features. The other part of Thunderbird’s mission is more personal: Respecting your privacy and putting you in control – not a corporation. 

We never show advertisements, and we never sell your data. That’s because Thunderbird is completely funded by gifts from generous people just like you. You keep this great software free, and you keep us thriving! 

But accomplishing this mission is expensive. Consistently improving Thunderbird and keeping it competitive means ensuring your security in a constantly changing landscape of mail providers. It means maintaining complex server infrastructure. It means fixing bugs and updating old code. It means striving for full accessibility and a refreshing, modern design. 

Help Thunderbird Thrive In 2023

So today, we’re asking for your help. Did you know that development of Thunderbird is funded by less than 1% of the people who use and enjoy it? 

If you find value in using Thunderbird, please consider giving a gift to support it. Your contributions make a huge difference. And if you’ve already donated this year, THANK YOU!

Thank you for using Thunderbird, and thank you for trusting us with your important daily communications.

Hacks.Mozilla.Org: Improving Firefox stability with this one weird trick

Mozilla planet - ti, 22/11/2022 - 15:16

The first computer I owned shipped with 128 KiB of RAM and to this day I’m still jarred by the idea that applications can run out of memory given that even 15-year-old machines often shipped with 4 GiB of memory. And yet it’s one of the most common causes of instability experienced by users and in the case of Firefox the biggest source of crashes on Windows.

As such, at Mozilla, we spend significant resources trimming down Firefox memory consumption and carefully monitoring the changes. Some extra efforts have been spent on the Windows platform because Firefox was more likely to run out of memory there than on macOS or Linux. And yet none of those efforts had the impact of a cool trick we deployed in Firefox 105.

But first things first, to understand why applications running on Windows are more prone to running out of memory compared to other operating systems it’s important to understand how Windows handles memory.

All modern operating systems allow applications to allocate chunks of the address space. Initially these chunks only represent address ranges that aren’t backed by physical memory unless data is stored in them. When an application starts using a bit of address space it has reserved, the OS will dedicate a chunk of physical memory to back it, possibly swapping out some existing data if need be. Both Linux and macOS work this way, and so does Windows except that it requires an extra step compared to the other OSes.

After an application has requested a chunk of address space it needs to commit it before being able to use it. Committing a range requires Windows to guarantee it can always find some physical memory to back it. Afterwards, it behaves just like Linux and macOS. As such Windows limits how much memory can be committed to the sum of the machine’s physical memory plus the size of the swap file.

This resource – known as commit space – is a hard limit for applications. Memory allocations will start to fail once the limit is reached. In operating system speech this means that Windows does not allow applications to overcommit memory.

One interesting aspect of this system is that an application can commit memory that it won’t use. The committed amount will still count against the limit even if no data is stored in the corresponding areas and thus no physical memory has been used to back the committed region. When we started analyzing out of memory crashes we discovered that many users still had plenty of physical memory available – sometimes gigabytes of it – but were running out of commit space instead.

Why was that happening? We don’t really know but we made some educated guesses: Firefox tracks all the memory it uses and we could account for all the memory that we committed directly.

However, we have no control over Windows system libraries and in particular graphics drivers. One thing we noticed is that graphics drivers commit memory to make room for textures in system memory. This allows them to swap textures out of the GPU memory if there isn’t enough and keep them in system memory instead. A mechanism that is similar to how regular memory can be swapped out to disk when there is not enough RAM available. In practice, this rarely happens, but these areas still count against the limit.

We had no way of fixing this issue directly but we still had an ace up our sleeve: when an application runs out of memory on Windows it’s not outright killed by the OS, its allocation simply fails and it can then decide what it does by itself.

In some cases, Firefox could handle the failed allocation, but in most cases, there is no sensible or safe way to handle the error and it would need to crash in a controlled way… but what if we could recover from this situation instead? Windows automatically resizes the swap file when it’s almost full, increasing the amount of commit space available. Could we use this to our advantage?

It turns out that the answer is yes, we can. So we adjusted Firefox to wait for a bit instead of crashing and then retry the failed memory allocation. This leads to a bit of jank as the browser can be stuck for a fraction of a second, but it’s a lot better than crashing.

There’s also another angle to this: Firefox is made up of several processes and can survive losing all of them but the main one. Delaying a main process crash might lead to another process dying if memory is tight. This is good because it would free up memory and let us resume execution, for example by getting rid of a web page with runaway memory consumption.

If a content process died we would need to reload it if it was the GPU process instead the browser would briefly flash while we relaunched it; either way, the result is less disruptive than a full browser crash. We used a similar trick in Firefox for Android and Firefox OS before that and it worked well on both platforms.

This little trick shipped in Firefox 105 and had an enormous impact on Firefox stability on Windows. The chart below shows how many out-of-memory browser crashes were experienced by users per active usage hours:

Firefox trick

You’re looking at a >70% reduction in crashes, far more than our rosiest predictions.

And we’re not done yet! Stalling the main process led to a smaller increase in tab crashes – which are also unpleasant for the user even if not nearly as annoying as a full browser crash – so we’re cutting those down too.

Last but not least we want to improve Firefox behavior in low-memory scenarios by responding differently to cases where we’re low on commit space and cases where we’re low on physical memory, this will reduce swapping and help shrink Firefox footprint to make room for other applications.

I’d like to send special thanks to my colleague Raymond Kraesig who implemented this “trick”, carefully monitored its impact and is working on the aforementioned improvements.

The Talospace Project: Firefox 107 on POWER

Mozilla planet - fr, 18/11/2022 - 02:50
Firefox 107 is out, a modest update, though there are some developer-facing changes. As before linking still requires Dan Horák's patch from bug 1775202 or the browser won't link on 64-bit Power ISA (alternatively put --disable-webrtc in your .mozconfig if you don't need WebRTC). Otherwise the build works with the .mozconfigs from Firefox 105 and the PGO-LTO patch from Firefox 101.

Mozilla Release Management Team: Firefox Regional feedback: Let's start with Europe

Mozilla planet - fr, 18/11/2022 - 01:00

We work hard as an organization to ship the best browser possible every 4 weeks with about 1000 new patches per release.

We ship new features to make our browser useful and easy to use. We also do platform work to be able to render new sites and web applications while remaining compatible with millions of websites created a decade (or more) ago.

This ongoing work also includes updating our translations in more than 100 languages thanks to our impressive community of localizers.

Yes, we want to make sure that Firefox can be used everywhere by everybody.

But could we maybe do better with a tighter feedback loop from our local communities?

Let’s give a few examples from our bug tracker:

Usually, major issues that may impact users in a specific country are fixed before we ship the final release, but occasionally we discover them after shipping and have to ship a fix in a dot release.

We talked about significant breakage with a regional impact, but what about papercuts?

Web compatibility, incorrect translations, internationalization issues, PiP subtitles support, certificates… The list of potential problems in a region that may affect our users is long and we may not know about them.

Maybe these issues are discussed in places we don’t know about, in languages we don’t speak. Maybe these issues are already filed in our bug tracker but don’t get prioritized correctly because we don’t know about their regional impact. Maybe a handful of specific regional issues are making Firefox hard to use in a specific country and the information is out there. Maybe all we need is somebody who understands these issues to surface these bugs in Bugzilla to our developers.

In a nutshell, we don’t know what we don’t know.

That is why I intend to work on studying and setting up basic feedback mechanisms to evaluate the health of Firefox in a few European countries so as to help my team (Release Management) prioritize product fixes for existing bugs which have the highest impact on our users and also to get help identifying regressions on our pre-release channels (Nightly, Beta, Developer Edition).

My very first goal is to make contacts with Mozillians in a handful of European countries (France, Germany, Italy, Poland, Spain) 1 that could help me identify issues that affect them locally, identify their top web compatibility issues, and maybe relay a general message for community feedback on pre-release channels.

To that effect, I created a Local Firefox room on the Mozilla Matrix instance. If you are interested in collaborating with me on this project, you are very welcome to join it and say hello (my nick is Pascal). I can speak with you in French and Spanish as well if you don’t feel comfortable speaking in English.



  1. I am focusing on a few European countries for timezone and bandwidth reasons since I’ll do that alongside my role as a Firefox Release Manager, but I am open to feedback from other regions as well of course.

Mozilla Addons Blog: Manifest v3 signing available November 21 on Firefox Nightly

Mozilla planet - to, 17/11/2022 - 15:00

Starting November 21, 2022 add-on developers are welcome to upload their Firefox Manifest version 3 (MV3) compatible extensions to (AMO) and have them signed as MV3 extensions. Getting an early jump on MV3 signing enables you to begin testing your extension’s future functionality on Nightly to ensure a smooth eventual transition to MV3 in Firefox.

To be clear, Firefox will continue to support MV2 extensions for the foreseeable future, even as we welcome MV3 extensions in the release to general availability in Firefox 109 (January 17, 2023). Our goal has been to ensure a seamless transition from MV2 to MV3 for extension developers. Taking a gradual approach and gathering feedback as MV3 matures, we anticipate opportunities will emerge over time to modify our initial MV3 offering. In these instances, we intend to take the time necessary to make informed decisions about our approach.

Towards the end of 2023 — once we’ve had time to evaluate and assess MV3’s rollout (including identifying important MV2 use cases that will persist into MV3) — we’ll decide on an appropriate timeframe to deprecate MV2. Once this timeframe is established, we’ll communicate MV2’s closure process with advance notice. For now, please see this guide for supporting both MV2 and MV3 versions of your extension on AMO.

Mozilla’s vision for Firefox MV3

Firefox MV3 offers simplified and consolidated APIs, enhanced security and privacy mechanisms, and functionality to better support mobile platforms. As we continue to collaborate with other browser vendors and the developer community to shape MV3, we recognize cross-browser compatibility as a fundamental consideration. That said, we’re also implementing distinct elements to suit Firefox’s product and community needs. We want to give extension developers creative flexibility and choice, while ensuring users maintain access to the highest standards of extension customization and security. Firefox MV3 stands apart from other iterations of MV3 in two critical ways:

  1. While other browser vendors introduced declarativeNetRequest (DNR) in favor of blocking Web Request in MV3, Firefox MV3 continues to support blocking Web Request and will support a compatible version of DNR in the future. We believe blocking Web Request is more flexible than DNR, thus allowing for more creative use cases in content blockers and other privacy and security extensions. However, DNR also has important performance and compatibility characteristics we want to support.
  2. Firefox MV3 offers Event Pages as the background script in lieu of service workers, though we plan to support service workers in the future for compatibility. Event Pages offer benefits like DOM and Web APIs that aren’t available to service workers, while also generally providing a simpler migration path.

Over subsequent releases next year, we’ll continue to expand Firefox MV3 compatibility.

MV3 also ushers an exciting user interface change in the form of the new extensions button (already available on Firefox Nightly). This will give users direct control over which extensions can access specific web sites.

The extensions button will give Firefox users direct control over website specific extension permissions.

Users are able to review, grant, or revoke MV3 extension access to any website. MV2 extensions will display in the button interface, but permissions access is unavailable. Please see this post for more information about the new extensions button.

If you’re planning to migrate your MV2 extension to MV3, there are steps you can take today to get started. We always encourage feedback from our developer community, so don’t hesitate to get in touch:

Mozilla Addons Blog: Extensions button and how to handle permissions in Manifest V3

Mozilla planet - to, 17/11/2022 - 12:46

Manifest V3 (MV3) is bringing new user-facing changes to Firefox, including an extensions button to manage installed and enabled browser extension permissions (origin controls), providing Firefox users control over extension access to their browsers. The first building blocks of this button were added to Nightly in Firefox 107 and will become available with the general release of MV3 in Firefox 109.

Extensions button

The extensions button will give Firefox users direct control over website specific extension permissions.

In MV2, host permissions are granted by the user at the time of install and there’s no elegant way for the user to change this setting (short of uninstalling/reinstalling and choosing different permissions). But with the new extensions button in MV3 in Firefox, users will have easy access and persistent control over which extensions can access any web page, at any time. Users are free to grant ongoing access to a website, or make a choice per visit. To enable this, MV3 treats host permissions (listed in the extension manifest) as opt-in.

The button panel will display the user’s installed and enabled extensions and their current permission state. In addition to managing host permissions, the panel also allows the user to manage, remove, or report the extension. Extensions with browser actions will behave similarly in the toolbar as in the panel.

Manifest V2 (MV2) extensions will also display in the panel; however users can’t take actions for MV2 host permissions since those were granted at installation and this choice cannot be reversed in MV2 without uninstalling the extension and starting again.

You can also find more information about the extensions button from

How to deal with opt-in permissions in extension code

The Permissions API provides a way for developers to read and request permissions.

With permissions.request(), you can request specific permissions that have been defined as optional permissions in the manifest:

const permissionsToRequest = { permissions: ["bookmarks", "history"], origins: [""] } async function requestPermissions() { function onResponse(response) { if (response) { console.log("Permission was granted"); } else { console.log("Permission was refused"); } return browser.permissions.getAll(); } const response = await browser.permissions.request(permissionsToRequest); const currentPermissions = await onResponse(response); console.log(`Current permissions:`, currentPermissions); }

This is handy when the request for permissions is tied to a user action like selecting a context menu item. Note that you cannot request for a permission that is not defined in the manifest.

Other times, you’ll want to react to a permission being granted or removed. This can be done with permissions.onAdded and permissions.onRemoved respectively.

function handleAdded(permissions) { console.log(`New API permissions: ${permissions.permissions}`); console.log(`New host permissions: ${}`); } browser.permissions.onAdded.addListener(handleAdded);

Finally, you can check for already existing permissions in two different ways: permissions.getAll() returns a list of all granted permissions and permissions.contains(permissionsToCheck) checks for specific permissions and resolves to true if, and only if, all checked permissions are granted.

// Extension permissions are: // "webRequest", "tabs", "*://**" let testPermissions1 = { origins: ["*://"], permissions: ["tabs"] }; const testResult1 = await browser.permissions.contains(testPermissions1); console.log(testResult1); // true

We always encourage feedback from our developer community, so don’t hesitate to get in touch:

Like regulators around the world, the US Federal Trade Commission (FTC) is exploring the possibility of new rules to protect consumer privacy online. We’re excited to see the FTC take this important step and ask key questions surrounding commercial surveillance and data security practices, from advertising and transparency to data collection and deceptive design practices.

Mozilla has a long track record on privacy. It’s an integral aspect of our Manifesto, where we state that individuals’ security and privacy on the internet are fundamental and must not be treated as optional. It’s evidenced in our products and in our collaboration with others in industry to forge solutions to create a better, more private online experience.

But we can’t do it alone. Without rules of the road, sufficient incentive won’t exist to shift the rest of the industry to more privacy preserving practices. To meet that need, we’ve called for comprehensive privacy legislation like the American Data Privacy and Protection Act (ADPPA), greater ad transparency, and strong enforcement around the world. In our latest submission to the FTC, we detail the urgent need for US regulators and policymakers to take action to create a healthier internet.

At a high level, our comments focus on:

Privacy Practices Online: Everyone should have control over their personal data, understand how it’s obtained and used, and be able to access, modify, or delete it. To that end, Mozilla has long advocated for companies to adopt better privacy practices through our Lean Data Practices methodology. It’s also important that rules govern not just the collection of data, but the uses of that data in order to limit harmful effects – from the impact of addictive user interfaces on kids to the use of recommendation systems to discrimination in housing and jobs.

Privacy Preserving Advertising: The way in which advertising is conducted today is broken and causes more harm than good.  At the same time, we believe there’s nothing inherently wrong with digital advertising. It supports a large section of services provided on the web and it is here to stay, in some form. A combination of new research, technical solutions, increased public awareness, and effective regulatory enforcement can reform advertising for the future of the web.

Deceptive Design Practices: Consumers are being tricked into handing over their data with deceptive patterns, then that data is used to manipulate them. The use of deceptive design patterns results in consumer harms including limited or frustrated choice, lower quality, lower innovation, poor privacy, and unfair contracts. This is bread-and-butter deception – the online manifestation of what the FTC was established to address – and it is critical that the FTC has the authority to take action against such deception.

Automated Decision Making Systems (ADMS): For years, research and investigative reporting have uncovered instances of ADMS that cause or enable discrimination, surveillance, or other harms to individuals and communities. The risks stemming from ADMS are particularly grave where these systems affect, for example, people’s livelihoods, safety, and liberties. We need enforceable rules that hold developers and deployers of ADMS to a higher standard, built on the pillars of transparency, accountability, and redress.

Systemic Transparency and Data Sharing: We encourage the FTC to strengthen the mechanisms that empower policymakers and trusted experts to better understand what is happening on major internet platforms. To achieve this, we need greater access to platform data (subject to strong user privacy protections), greater research tooling, and greater protections for researchers.

Practices surrounding consumer data on the internet today, and the resulting societal harms, have put people and trust at risk. The future of privacy online requires industry to step up to protect and empower people online, and demands that lawmakers and regulators implement frameworks that create the ecosystem and incentive for a better internet ahead.
