Mozilla Open Policy & Advocacy Blog: Should Patent Law Be a First Amendment Issue?

Mozilla planet - vr, 14/04/2017 - 01:10

On Monday April 17th, Mozilla and Stanford Law are presenting a panel about intellectual property law and the First Amendment.

We’ll talk about how IP law and the First Amendment intersect in IP disputes, eligibility tests, and the balance of interests between patent holders and users.

Judge Mayer’s concurring opinion last year in Intellectual Ventures I LLC v. Symantec Corp, has put the debate over the First Amendment and boundaries of patent protection back in the spotlight.

Our all star panel will discuss both sides of the debate.


Dan Burk, professor of law at UC Irvine School of Law.

Sandra Park, Senior Staff Attorney for the ACLU Women’s Rights Project.

Robert Sachs, a partner at Fenwick & West LLP, a leading Intellectual Property law firm.

Wendy Seltzer, Strategy Lead and Policy Counsel for the World Wide Web Consortium.

Elvin Lee, Product and Commercial Counsel at Mozilla, will moderate the event.

We’ll also hear opening remarks from professor Mark A. Lemley, who serves as the Director of the Stanford Program in Law, Science and Technology.

Topics and questions we’ll cover
  • Does patent law create conflicts with the First Amendment?
  • Do the subject-matter eligibility tests created by the Supreme Court (e.g., Alice) mitigate or impact any potential First Amendment issues?
  • How does the First Amendment’s intersection with patent law compare to other IP and regulatory contexts?
  • What are the different competing interests for IP owners and creators?
  • Registration of ‘offensive’ marks is currently being reviewed in light of the First Amendment. Are there any parallels to the grant of patent protection by the USPTO, or subsequent enforcement?

AirMozilla and Mozilla’s Facebook page will carry the livestream for this event. We hope you’ll tune in.

Hacks.Mozilla.Org: Replace Bootstrap Layouts with CSS Grid

Mozilla planet - do, 13/04/2017 - 17:20

In March, Mozilla released Firefox 52, which added support for CSS Grid Layout. If you aren’t familiar with CSS Grid, it is a two-dimensional layout system for the web that allows us to create layout patterns natively in the browser. This means we can easily recreate familiar grids using just a few lines of CSS. It also means we can do a whole lot with CSS and layouts that wasn’t possible before… but more on that in a bit.

A quick note: This post isn’t meant to be a comprehensive primer for CSS Grid, and assumes a basic familiarity with CSS Grid. If you haven’t already, I’d recommend checking out the fantastic CSS Grid Layout page on MDN.

Layouts on the web have always been tricky. When the web was first introduced, there was no method for layouts. Then came tables (in tables, in tables, in tables). It was hackish and weird, but it worked. When CSS was introduced in the late 90s, developers were able to start using divs and floats for their designs and layouts. This eventually led to frameworks and grid systems that helped make sense of all of the “gotchas” like clearing floats, negative margins, responsive design and more. And that’s how things have been for years now. There are thousands of grid systems, but they are all, more or less, the same.

Now that CSS Grid Layout is a reality, I wanted to see what it would take to replace an existing grid framework with CSS Grid. For this experiment, I chose the popular Bootstrap framework.

I started by creating a basic site using the Bootstrap grid:

View it on CodePen.

So let’s break this down and convert it to use CSS Grid.

In Bootstrap, the .container class wraps everything and sets the width constraints. It also adds a padding to the left and right edges and centers everything. There isn’t much to change here. Just like with Bootstrap, the container class can be handy to use with CSS Grid. I recreated it like so:

.container { margin-left: auto; margin-right: auto; padding-left: 15px; padding-right: 15px; }

We can also add responsive breakpoints by adding the following:

@media (min-width: 992px) { .container { width: 970px; } }

Bootstrap uses the .row class to wrap columns and provide a negative margin on the left and right to negate the padding added by individual columns. Hacks like negative margins are no longer needed with CSS Grid, but if you’ve read the documentation, you’ll know that CSS Grid requires a grid container. The .row class is the perfect place to do this. Let me show you what I did, and then we’ll break it down.

.row { display: grid; grid-template-columns: repeat(12, 1fr); grid-gap: 20px; }

display: grid creates the grid container.

The grid-template-columns property defines the columns for the grid. You can use spaces to define each column individually, but here we utilize the repeat notation to define 12 equal-sized columns. 1fr refers to the width of the individual column. MDN defines the fr unit as a new unit which “represents a fraction of the available space in the grid container.” You can read more about fr units on MDN. You can also read more about the grid-template-columns property.

Finally, the grid-gap property is a shorthand property that defines both the amount of space between the columns and between rows of columns. Think of it as our gutter. You can read more about grid-gap here.

Now, all that’s left are the column classes. Bootstrap uses column classes such as .col-md-6 or .col-lg-8 to determine the number of columns a div should span. It also floats the div and adds padding to the left and right to create gutters between the columns. Recreating these classes is incredibly easy thanks to the .grid-column shorthand property. For example, if we wanted to recreate the .col-md-6 class, we can use the following:

@media (min-width: 992px) { .col-md-6 { grid-column: span 6; } }

Simple, right? No floats. No padding. It just works. The grid-column shorthand specifies an item’s size and location. We can use span to indicate that this particular item should span six columns. The gutter is automatically taken care of because of the wrapper’s grid-gap property. You can learn more about the grid-column property here.

So what happens when you put it all together? Well, the website looks exactly the same, but we are able to completely remove the Bootstrap dependency and use native CSS Grids.

Check out the updated website on CodePen.

This type of experiment is a fun learning exercise, but it can also be dangerous. To borrow a line from wise philosopher Jeff Goldblum:

“You … were so preoccupied with whether or not you could, you didn’t stop to think if you should.”

We don’t want to limit CSS Grid by shoehorning it into a syntax that will limit its potential. We were able to easily recreate the Bootstrap grid, but CSS Grid is so much more powerful than any grid system that came before it. That’s because it is a web-native solution built from the ground up.

We are no longer locked into 12 column grids that float from left to right. Do you want to place elements in precise locations on the grid, independent of their HTML source order? Go for it. Do you want to create items that span multiple columns and rows? Not a problem. Check out this demo that Mozilla’s Craig Cook created to showcase various layout patterns. Try recreating some of those layouts using Bootstrap (hint: not possible). We are just scratching the surface of what CSS Grids can do.

If you want to learn more about CSS Grid, check out the following resources:

François Marier: Automatically renewing Let's Encrypt TLS certificates on Debian using Certbot

Mozilla planet - do, 13/04/2017 - 17:00

I use Let's Encrypt TLS certificates on my Debian servers along with the Certbot tool. Since I use the "temporary webserver" method of proving domain ownership via the ACME protocol, I cannot use the cert renewal cronjob built into Certbot.

Instead, this is the script I put in /etc/cron.daily/certbot-renew:

#!/bin/bash /usr/bin/certbot renew --quiet --pre-hook "/bin/systemctl stop apache2.service" --post-hook "/bin/systemctl start apache2.service" pushd /etc/ > /dev/null /usr/bin/git add letsencrypt DIFFSTAT="$(/usr/bin/git diff --cached --stat)" if [ -n "$DIFFSTAT" ] ; then /usr/bin/git commit --quiet -m "Renewed letsencrypt certs" echo "$DIFFSTAT" fi popd > /dev/null

It temporarily disables my Apache webserver while it renews the certificates and then only outputs something to STDOUT (since my cronjob will email me any output) if certs have been renewed.

Since I'm using etckeeper to keep track of config changes on my servers, my renewal script also commits to the repository if any certs have changed.

External Monitoring

In order to catch mistakes or oversights, I use ssl-cert-check to monitor my domains once a day:

ssl-cert-check -s -p 443 -q -a -e

I also signed up with Cert Spotter which watches the Certificate Transparency log and notifies me of any newly-issued certificates for my domains.

In other words, I get notified:

  • if my cronjob fails and a cert is about to expire, or
  • as soon as a new cert is issued.

The whole thing seems to work well, but if there's anything I could be doing better, feel free to leave a comment!

Daniel Pocock: What is the risk of using proprietary software for people who prefer not to?

Mozilla planet - wo, 12/04/2017 - 08:43

Jonas Öberg has recently blogged about Using Proprietary Software for Freedom. He argues that it can be acceptable to use proprietary software to further free and open source software ambitions if that is indeed the purpose. Jonas' blog suggests that each time proprietary software is used, the relative risk and reward should be considered and there may be situations where the reward is big enough and the risk low enough that proprietary software can be used.

A question of leadership

Many of the free software users and developers I've spoken to express frustration about how difficult it is to communicate to their family and friends about the risks of proprietary software. A typical example is explaining to family members why you would never install Skype.

Imagine a doctor who gives a talk to school children about the dangers of smoking and is then spotted having a fag at the bus stop. After a month, if you ask the children what they remember about that doctor, is it more likely to be what he said or what he did?

When contemplating Jonas' words, it is important to consider this leadership factor as a significant risk every time proprietary software or services are used. Getting busted with just one piece of proprietary software undermines your own credibility and posture now and well into the future.

Research has shown that when communicating with people, what they see and how you communicate is ninety three percent of the impression you make. What you actually say to them is only seven percent. When giving a talk at a conference or a demo to a client, or communicating with family members in our everyday lives, using a proprietary application or a product or service that is obviously proprietary like an iPhone or Facebook will have far more impact than the words you say.

It is not only a question of what you are seen doing in public: somebody who lives happily and comfortably without using proprietary software sounds a lot more credible than somebody who tries to explain freedom without living it.

The many faces of proprietary software

One of the first things to consider is that even for those developers who have a completely free operating system, there may well be some proprietary code lurking in their BIOS or other parts of their hardware. Their mobile phone, their car, their oven and even their alarm clock are all likely to contain some proprietary code too. The risks associated with these technologies may well be quite minimal, at least until that alarm clock becomes part of the Internet of Things and can be hacked by the bored teenager next door. Accessing most web sites these days inevitably involves some interaction with proprietary software, even if it is not running on your own computer.

There is no need to give up

Some people may consider this state of affairs and simply give up, using whatever appears to be the easiest solution for each problem at hand without thinking too much about whether it is proprietary or not.

I don't think Jonas' blog intended to sanction this level of complacency. Every time you come across a piece of software, it is worth considering whether a free alternative exists and whether the software is really needed at all.

An orderly migration to free software

In our professional context, most software developers come across proprietary software every day in the networks operated by our employers and their clients. Sometimes we have the opportunity to influence the future of these systems. There are many cases where telling the client to go cold-turkey on their proprietary software would simply lead to the client choosing to get advice from somebody else. The free software engineer who looks at the situation strategically may find that it is possible to continue using the proprietary software as part of a staged migration, gradually helping the user to reduce their exposure over a period of months or even a few years. This may be one of the scenarios where Jonas is sanctioning the use of proprietary software.

On a technical level, it may be possible to show the client that we are concerned about the dangers but that we also want to ensure the continuity of their business. We may propose a solution that involves sandboxing the proprietary software in a virtual machine or a DMZ to prevent it from compromising other systems or "calling home" to the vendor.

As well as technical concerns about a sudden migration, promoters of free software frequently encounter political issues as well. For example, the IT manager in a company may be five years from retirement and is not concerned about his employer's long term ability to extricate itself from a web of Microsoft licenses after he or she has the freedom to go fishing every day. The free software professional may need to invest significant time winning the trust of senior management before he is able to work around a belligerant IT manager like this.

No deal is better than a bad deal

People in the UK have probably encountered the expression "No deal is better than a bad deal" many times already in the last few weeks. Please excuse me for borrowing it. If there is no free software alternative to a particular piece of proprietary software, maybe it is better to simply do without it. Facebook is a great example of this principle: life without social media is great and rather than trying to find or create a free alternative, why not just do something in the real world, like riding motorcycles, reading books or getting a cat or dog?

Burning bridges behind you

For those who are keen to be the visionaries and leaders in a world where free software is the dominant paradigm, would you really feel satisfied if you got there on the back of proprietary solutions? Or are you concerned that taking such shortcuts is only going to put that vision further out of reach?

Each time you solve a problem with free software, whether it is small or large, in your personal life or in your business, the process you went through strengthens you to solve bigger problems the same way. Each time you solve a problem using a proprietary solution, not only do you miss out on that process of discovery but you also risk conditioning yourself to be dependent in future.

For those who hope to build a successful startup company or be part of one, how would you feel if you reach your goal and then the rug is pulled out underneath you when a proprietary software vendor or cloud service you depend on changes the rules?

Personally, in my own life, I prefer to avoid and weed out proprietary solutions wherever I can and force myself to either make free solutions work or do without them. Using proprietary software and services is living your life like a rat in a maze, where the oligarchs in Silicon Valley can move the walls around as they see fit.

Adblock Plus: The plan towards offering Adblock Plus for Firefox as a Web Extension

Mozilla planet - wo, 12/04/2017 - 08:23

TL;DR: Sometime in autumn this year the current Adblock Plus for Firefox extension is going to be replaced by another, which is more similar to Adblock Plus for Chrome. Brace for impact!

What are Web Extensions?

At some point, Web Extensions are supposed to become a new standard for creating browser extensions. The goal is writing extensions in such a way that they could run on any browser without any or only with minimal modifications. Mozilla and Microsoft are pursuing standardization of Web Extensions based on Google Chrome APIs. And Google? Well, they aren’t interested. Why should they be, if they already established themselves as an extension market leader and made everybody copy their approach.

It isn’t obvious at this point how Web Extensions will develop. The lack of interest from Google isn’t the only issue here; so far the implementation of Web Extensions in Mozilla Firefox and Microsoft Edge shows very significant differences as well. It is worth noting that Web Extensions are necessarily less powerful than the classic Firefox extensions, even though many shortcomings can probably be addressed. Also, my personal view is that the differences between browsers are either going to result in more or less subtle incompatibilities or in an API which is limited by the lowest common denominator of all browsers and not good enough for anybody.

So why offer Adblock Plus as a Web Extension?

Because we have no other choice. Mozilla’s current plan is that Firefox 57 (scheduled for release on November 14, 2017) will no longer load classic extensions, and only Web Extensions are allowed to continue working. So we have to replace the current Adblock Plus by a Web Extension by then or ideally even by the time Firefox 57 is published as a beta version. Otherwise Adblock Plus will simply stop working for the majority of our users.

Mind you, there is no question why Mozilla is striving to stop supporting classic extensions. Due to their deep integration in the browser, classic extensions are more likely to break browser functionality or to cause performance issues. They’ve also been delaying important Firefox improvements due to compatibility concerns. This doesn’t change the fact that this transition is very painful for extension developers, and many existing extensions won’t take this hurdle. Furthermore, it would have been better if the designated successor of the classic extension platform were more mature by the time everybody is forced to rewrite their code.

What’s the plan?

Originally, we hoped to port Adblock Plus for Firefox properly. While using Adblock Plus for Chrome as a starting point would require far less effort, this extension also has much less functionality compared to Adblock Plus for Firefox. Also, when developing for Chrome we had to make many questionable compromises that we hoped to avoid with Firefox.

Unfortunately, this plan didn’t work out. Adblock Plus for Firefox is a large codebase and rewriting it all at once without introducing lots of bugs is unrealistic. The proposed solution for a gradual migration doesn’t work for us, however, due to its asynchronous communication protocols. So we are using this approach to start data migration now, but otherwise we have to cut our losses.

Instead, we are using Adblock Plus for Chrome as a starting point, and improving it to address the functionality gap as much as possible before we release this version for all our Firefox users. For the UI this means:

  • Filter Preferences: We are working on a more usable and powerful settings page than what is currently being offered by Adblock Plus for Chrome. This is going to be our development focus, but it is still unclear whether advanced features such as listing filters of subscriptions or groups for custom filters will be ready by the deadline.
  • Blockable Items: Adblock Plus for Chrome offers comparable functionality, integrated in the browser’s Developer Tools. Firefox currently doesn’t support Developer Tools integration (bug 1211859), but there is still hope for this API to be added by Firefox 57.
  • Issue Reporter: We have plans for reimplementing this important functionality. Given all the other required changes, this one has lower priority, however, and likely won’t happen before the initial release.

If you are really adventurous you can install a current development build here. There is still much work ahead however.

What about applications other than Firefox Desktop?

The deadline only affects Firefox Desktop for now; in other applications classic extensions will still work. However, it currently looks like by Firefox 57 the Web Extensions support in Firefox Mobile will be sufficient to release a Web Extension there at the same time. If not, we still have the option to stick with our classic extension on Android.

As to SeaMonkey and Thunderbird, things aren’t looking well there. It’s doubtful that these will have noteworthy Web Extensions support by November. In fact, it’s not even clear whether they plan to support Web Extensions at all. And unlike with Firefox Mobile, we cannot publish a different build for them (Addons.Mozilla.Org only allows different builds per operating system, not per application). So our users on SeaMonkey and Thunderbird will be stuck with an outdated Adblock Plus version.

What about extensions like Element Hiding Helper, Customizations and similar?

Sadly, we don’t have the resources to rewrite these extensions. We just released Element Hiding Helper 1.4, and it will most likely remain as the last Element Hiding Helper release. There are plans to integrate some comparable functionality into Adblock Plus, but it’s not clear at this point when and how it will happen.

Mozilla Addons Blog: AMO Has a New Look on Android

Mozilla planet - di, 11/04/2017 - 20:57

The mobile version of (AMO) recently debuted a new appearance. It’s not a complete redesign, but rather the start of an iterative process that will take months to fully transform AMO for mobile. The new look is also a preview of what’s to come for desktop AMO. Once the mobile design elements mature, we’ll apply the same concepts to desktop, likely sometime later this year.

“Parity between the two platforms is a high priority,” says Sr. Visual Designer Philip Walmsley. “We’re using mobile to test and learn what works, and uplifting that into the desktop designs. And anything new we discover along the way on desktop will be designed back into mobile, as well.”

Our main goal was to make browsing add-ons more intuitive and effortless. To that end, the new design presents content in a cleaner, more streamlined manner. There are fewer buttons to tap, but the ones that remain are bold and clear.

Illustrated in the images above, the homepage displays a subset of categories represented primarily though iconography… The density of information on an add-on detail page is more balanced now, with only essential information in clear view… and theme previews are bigger and screenshots more prominent.

There’s a bit more color, too. In general much of the aesthetic was in need of a modernizing overhaul. These recent changes are just the start. Plenty more to come. If you’re exploring the new AMO on your Android device and spot a bug, please feel free to let us know about it.

Joel Maher: Project Stockwell (reduce intermittents) – April 2017

Mozilla planet - di, 11/04/2017 - 19:06

I am 1 week late in posting the update for Project Stockwell.  This wraps up a full quarter of work.  After a lot of concerns raised by developers about a proposed new backout policy, we moved on and didn’t change too much although we did push a little harder and I believe we have disabled more than we fixed as a result.

Lets look at some numbers:

Week Starting 01/02/17 02/27/17 03/24/17 Orange Factor 13.76 9.06 10.08 # P1 bugs 42 32 55 OF(P2) 7.25 4.78 5.13

As you can see we increased in March on all numbers- but overall a great decrease so far in 2017.

There have been a lot of failures which have lingered for a while which are not specific to a test.  For example:

  • windows 8 talos has a lot of crashes (work is being done in bug 1345735)
  • reftest crashes in bug 1352671.
  • general timeouts in jobs in bug 1204281.
  • and a few other leaks/timeouts/crashes/harness issues unrelated to a specific test
  • infrastructure issues and tier-3 jobs

While these are problematic, we see the overall failure rate is going down.  In all the other bugs where the test is clearly a problem we have seen many fixes which and responses to bugs from so many test owners and developers.  It is rare that we would suggest disabling a test and it was not agreed upon, and if there was concern we had a reasonable solution to reduce or fix the failure.

Speaking of which, we have been tracking total bugs, fixed, disabled, etc with whiteboard tags.  While there was a request to not use “stockwell” in the whiteboard tags and to make them more descriptive, after discussing this with many people we couldn’t come to agreement on names or what to track and what we would do with the data- so for now, we have remained the same.  Here is some data:

03/07/17 04/11/17 total 246 379 fixed 106 170 disabled 61 91 infrastructure 11 17 unknown 44 60 needswork 24 38 % disabled 36.53% 34.87%

What is interesting is that prior to march we had disabled 36.53% of the fixes, but in March when we were more “aggressive” about disabling tests, the overall percentage went down.  In fact this is a cumulative number for the year, so for the month of March alone we only disable 31.91% of the fixed tests.  Possibly if we had disabled a few more tests the overall numbers would have continued to go down vs slightly up.

A lot of changes took place on the tree in the last month, some interesting data on newer jobs:

  • taskcluster windows 7 tests are tier-2 for almost all windows VM tests
  • autophone is running all media tests which are not crashing or perma failing
  • disabled external media tests on linux platforms
  • added stylo mochitest and mochitest-chrome
  • fixed stylo reftests to run in e10s mode and on ubuntu 16.04

Upcoming job changes that I am aware of:

  • more stylo tests coming online
  • more linux tests moving to ubuntu 16.04
  • push to green up windows 10 taskcluster vm jobs

Regarding our tests, we are working on tracking new tests added to the tree, what components they belong in, what harness they run in, and overall how many intermittents we have for each component and harness.  Some preliminary work shows that we added 942 mochitest*/xpcshell tests in Q1 (609 were imported webgl tests, so we wrote 333 new tests, 208 of those are browser-chrome).  Given the fact that we disabled 91 tests and added 942, we are not doing so bad!

Looking forward into April and Q2, I do not see immediate changes to a policy needed, maybe in May we can finalize a policy and make it more formal.  With the recent re-org, we are now in the Product Integrity org.  This is a good fit, but dedicating full time resources to sheriffing and tooling for the sake of project stockwell is not in the mission.  Some of the original work will continue as it serves many purposes.  We will be looking to formalize some of our practices and tools to make this a repeatable process to ensure that progress can still be made towards reducing intermittents (we want <7.0) and creating a sustainable ecosystem for managing these failures and getting fixes in place.

Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

No RFCs were approved this week.

Final Comment Period

Every week the team announces the 'final comment period' for RFCs and key PRs which are reaching a decision. Express your opinions now. This week's FCPs are:

New RFCs Style RFCs

Style RFCs are part of the process for deciding on style guidelines for the Rust community and defaults for Rustfmt. The process is similar to the RFC process, but we try to reach rough consensus on issues (including a final comment period) before progressing to PRs. Just like the RFC process, all users are welcome to comment and submit RFCs. If you want to help decide what Rust code should look like, come get involved!

We're making good progress and the style is coming together. If you want to see the style in practice, check out our example or use the Integer32 Playground and select 'Proposed RFC' from the 'Format' menu. Be aware that implementation is work in progress.

Issues in final comment period:

Good first issues:

We're happy to mentor these, please reach out to us in #rust-style if you'd like to get involved

Nobody expects the Rust Evangelism Strike Force! Our chief weapon is surprise, surprise and fearless concurrency... fearless concurrency and surprise... our two weapons are fearless concurrency and surprise, and ruthless efficiency our three, weapons are fearless concurrency, and surprise, and ruthless efficiency, and an almost fanatical devotion to zero-cost abstractions. Our four, no--amongst our weapons... Amongst our weaponry... are, such elements as fearless concurrency, surprise... I'll come in again.
