Blast from the Past: I filed a bug against Firefox 3.6.6

A screenshot of the old bugzilla duplicate finder UI with the text inside table cells not rendering at allOn June 30, 2010 I was:

  • Sleepy. My daughter had just been born a few months prior and was spending her time pooping, crying, and not sleeping (as babies do).
  • Busy. I was working at Research in Motion (it would be three years before it would be renamed BlackBerry) on the BlackBerry Browser for BlackBerry 6.0. It was a big shift for us since that release was the first one using WebKit instead of the in-house “mango” rendering engine written in BlackBerry-mobile-dialect Java.
  • Keen. Apparently I was filing a bug against Firefox 3.6.6?!

Yeah. I had completely forgotten about this. Apparently while reading my RSS feeds in Google Reader (that doesn’t make me old, does it?) taking in news from Dragonmount about the Wheel of Time (so I guess I’ve always been a nerd, then) the text would sometimes just fail to render. I even caught it happening on the old Bugzilla “possible duplicate finder” UI (see above).

The only reason I was reminded this exists was because I received bugmail on my personal email address when someone accidentally added and removed themselves from the Cc list.

Pretty sure this bug, being no longer reproducible, still in UNCONFIRMED state, and filed against a pre-rapid-release version Firefox is something I should close. Yeah, I’ll just go and do that.

The Photonization of about:telemetry

This summer I mentored :flyingrub for a Google Summer of Code project to redesign about:telemetry. You can read his Project Submission Document here.

Background

Google Summer of Code is a program funded by Google to pay students worldwide to contribute in meaningful ways to open source projects.

about:telemetry is a piece of Firefox’s UI that allows users to inspect the anonymous usage data we collect to improve Firefox. For instance, we look at the maximum number of tabs our users have open during a session (someone or several someones have more than one thousand tabs open!). If you open up a tab in Firefox and type in about:telemetry (then press Enter), you’ll see the interface we provide for users to examine their own data.

Mozilla is committed to putting users in control of their data. about:telemetry is a part of that.

Then

When :flyingrub started work on about:telemetry, it looked like this (Firefox 55):

oldAboutTelemetry

It was… functional. Mostly it was intended to be used by developers to ensure that data collection changes to Firefox actually changed the data that was collected. It didn’t look like part of Firefox. It didn’t look like any other about: page (browse to about:about to see a list of about: pages). It didn’t look like much of anything.

Now

After a few months of polishing and tweaking and input from UX, it looks like this (Firefox Nightly 57):

newAboutTelemetry

Well that’s different, isn’t it?

It has been redesigned to follow the Photon Design System so that it matches how Firefox 57 looks. It has been reorganized into more functional groups, has a new top-level search, and dozens of small tweaks to usability and visibility so you can see more of your data at once and get to it faster.

Soon

Just because Google Summer of Code is done doesn’t mean about:telemetry is done. Work on about:telemetry continues… and if you know some HTML, CSS, and JavaScript you can help out! Just pick a bug from the “Depends on” list here, and post a comment asking if you can help out. We’ll be right with you to help get you started. (Though you may wish to read this first, since it is more comprehensive than this blog post.)

Even if you can’t or don’t want to help out, you can take sneak a peek at the new design by downloading and using Firefox Nightly. It is blazing fast with a slick new design and comes with excellent new features to help be your agent on the Web.

We expect :flyingrub will continue to contribute to Firefox (as his studies allow, of course. He is a student, and his studies should be first priority now that GSoC is done), and we thank him very much for all of his good work this Summer.

All Aboard the Release Train!

I’m working on a dashboard (a word which here means a website that has plots on it) to show Firefox crashes per channel over time. The idea is to create a resource for Release Management to figure out if there’s something wrong with a given version of Firefox with enough lead time to then do something about it.

It’s entering its final form (awaiting further feedback from relman and others to polish it) and while poking around (let’s call it “testing”) I noticed a pattern:auroramcscrashes

Each one of those spikes happens on a “merge day” when the Aurora channel (the channel powering Firefox Developer Edition) updates to the latest code from the Nightly channel (the channel powering Firefox Nightly). From then on, only stabilizing changes are merged so that when the next merge day comes, we have a nice, stable build to promote from Aurora to the Beta channel (the channel powering Firefox Beta). Beta undergoes further stabilization on a slower schedule (a new build every week or two instead of daily) to become a candidate for the Release channel (which powers Firefox).

For what it’s worth, this is called the Train Model. It allows us to ship stable and secure code with the latest features every six-to-eight weeks to hundreds of millions of users. It’s pretty neat.

And what that picture up there shows is that it works. The improvement is especially noticeable on the Aurora branch where we go from crashing 9-10 times for every thousand hours of use to 3-4 times for every thousand hours.

Now, the number and diversity of users on the Aurora branch is limited, so when the code rides the trains to Beta, the crash rate goes up. Suddenly code that seemed stable across the Aurora userbase is exposed to previously-unseen usage patterns and configurations of hardware and software and addons. This is one of the reasons why our pre-release users are so precious to us: they provide us with the early warnings we need to stabilize our code for the wild diversity of our users as well as the wild diversity of the Web.

If you’d like to poke around at the dashboard yourself, it’s over here. Eventually it’ll get merged into telemetry.mozilla.org when it’s been reviewed and formalized.

If you have any brilliant ideas of how to improve it, or find any mistakes or bugs, please comment on the tracking bug where the discussion is currently ongoing.

If you’d like to help in an different way, consider installing Firefox Beta. It should look and act almost exactly like your current Firefox, but with some pre-release goodies that you get to use before anyone else (like how Firefox Beta 50 lets you use Reader Mode when you want to print a web page to skip all the unnecessary sidebars and ads). By doing this you are helping us ship the best Firefox we can.

Firefox Windows XP Exit Plan

7drhiqr

Last I reported, the future of Firefox’s Windows XP support was uncertain, even given long-standing plans for its removal.

With the filing of bug 1305453 and the commensurate discussion on firefox-dev, things are now much more certain. Firefox will (pending approval) be ending support for Windows XP and Windows Vista in Firefox 53 (scheduled release date: April 18, 2017).

Well, thanks for tuning in. I guess I can wrap up these posts and…

Okay, yes, you’re right. It isn’t that simple.

First, the actual day that Windows XP and Windows Vista users will cease getting Firefox updates is actually much later than April of 2017. Instead, those users will continue to receive security updates until April of 2018 because the version of Firefox 52 they’ll be getting is an Extended Support Release.

What is Firefox Extended Support Release (ESR)? It’s a version of Firefox for enterprises and other risk-averse users that receives security (and only security) updates for one year after initial release. This allows these change-weary users to still chose Firefox without having to consider how to support a major version release every six-to-eight weeks.

Windows XP and Vista users will be shunted from the normal roughly-six-weeks-per-version “Release” channel to the “ESR” channel for 52. New installs on Windows XP and Vista at that time will also be for ESR 52. This should ensure that our decreasing Windows XP+Vista userbase will be supported until they’ve finished diminishing into…

…well, okay that’s not simple either. In absolute terms, our Windows XP userbase has actually increased over the past six months or so. Some if not all of this is the end of the well-documented slump we see in user population over the Northern-hemisphere Summer (we’re now coming back up to Fall-Winter-Spring numbers). It is also possible that we’ve seen some ex-Chrome users fleeing Google’s drop of support from earlier this year.

Deseasonalized numbers for just WinXP users are hard to come by, so this is fairly speculative. One thing that’s for certain is that the diminishing Windows XP userbase trend I had previously observed (and was counting on seeing continue) is no longer in evidence.

So what happens if we reach April of 2018 and we still have millions and millions of Windows XP users still relying on Firefox to provide them with a safe way to navigate the increasingly-hostile environment of the Web?

No idea. I guess this means I’ll be continuing to blog about WinXP for a couple years yet.

Mozilla, Firefox, and Windows XP Support

windowsXPStartButton
Used with permission from Microsoft.

Last time I focused on what the Firefox Windows XP user population appeared to be. This time, I’m going to look into what such a large population means to Firefox and Mozilla.

Windows XP users of Firefox are geographically and linguistically diverse, and make up more than one tenth of the entire Firefox user population. Which is great, right? A large, diverse population of users… other open source projects only wish they had the luck.

Except Windows XP is past its end-of-life. Nearly two years past. This means it hasn’t been updated, maintained, serviced, or secured in longer than it takes Mars to make it around the Sun.

The Internet can be a scary place. There are people who want to steal your banking passwords, post your private pictures online, or otherwise crack open your computer and take and do what they want with what’s inside of it.

Generally, this is an arms race. Every time someone discovers a software vulnerability, software vendors rush to fix it before the Bad Guys can use it to exploit people’s computers.

The reason we feel safe enough to continue our modern life using computers for our banking, shopping, and communicating is because software vendors are typically better at this than the Bad Guys.

But what if you’re using Windows XP? Microsoft, the only software vendor who is permitted to fix vulnerabilities in Windows XP, has stopped fixing them.

This means each Windows XP vulnerability that is found remains exploitable. Forever.

These are just a few vulnerabilities that we know about.

And Windows XP isn’t just bad for Windows XP users.

There are a variety of crimes that can be committed only using large networks of “robot” machines (called “botnets“) under the control of a single Bad Guy. Machines can be recruited into botnets against their users’ will through security vulnerabilities in the software they are running. Windows XP’s popularity and lengthening list of known vulnerabilities might make it an excellent source of recruits.

With enough members, a botnet can then send spam emails in sufficient volume to overload mail servers, attack financial institutions, steal information from governmental agencies, and otherwise make the Internet a less nice place to be.

So Firefox has a large, diverse population of users whose very presence connected to the Internet is damaging the Web for us all.

And so does Google! At least for now. Google has announced that it will end Windows XP support for its Chrome browser in April 2016. (It previously announced end-of-life dates for April 2015, and then December 2015.)

So, as of April, Windows XP users will have only one choice for updated, serviced, maintained, and secured web browsing: Firefox.

Which puts Mozilla in a bit of a bind. The Internet is a global, public resource that Mozilla is committed to defend and improve.

Does improving the Internet mean dropping support for Windows XP so that users have no choice but to upgrade to be able to browse safely?

Or does improving the Internet mean continuing to support Windows XP so that those can at least still have a safe browser to access the Web?

Windows XP users might not have a choice in what Operating System their computers run. They might only be using it because they don’t know of an alternative or because they can’t afford to, aren’t allowed to, or are afraid to change.

Firefox is their best hope for security on the Web. And, after April, their only hope.

As of this writing, Firefox supports versions of Windows from XP SP2 on upwards. And this is likely to continue: the latest public discussion about Windows XP support was from last December, reacting to the latest of Google’s Windows XP support blog posts.

I can reiterate confidently: Firefox will continue to support Windows XP.

For now.

Mozilla will have to find a way to reconcile this with its mission. And Firefox will have to help.

Maybe Mozillians from around the world can seek out Windows XP users and put them in contact with local operations that can donate hardware or software or even just their time to help these users connect to the Internet safely and securely.

Maybe Firefox will start testing nastygrams to pop up at our Windows XP user base when they start their next browsing session: “Did you know that your operating system is older than many Mozillians?”, “It appears as though you are accessing the Internet using a close relative of the abacus”, “We have determined that this is the email address of your closest Linux User Group who can help you secure your computer”

…and you. Yeah, you. Do you know someone who might be running Windows XP? Maybe it’s your brother, or your Mother, or your Babbi. If you see a computer with a button that says “Start” at the bottom-left corner of the screen: you can fix that. There are resources in your community that can help.

Talk to your librarian, talk to the High School computer teacher, talk to a Mozillian! We’re friendly!

Together, we can save the Web.
