Mozilla has conducted one of the first – maybe even the first – studies into the effectiveness of browser choice screens, and they conclude: This research showed that browser choice screens have the potential to be effective. Well designed browser choice screens can improve competition, giving people meaningful choice and improving people’s satisfaction and feelings of control. And they can do all of this without overburdening people or taking too much of their time. What’s more, people have strong preferences: it turns out they want the ability to choose their default browser (rather than being assigned one by the operating system/device manufacturer); they also want to pick from a wider range of browsers.

On behalf of the Thunderbird team, Thunderbird Council, our global community of contributors, and our extended Mozilla family, I am incredibly excited to announce the initial launch of Thunderbird 115 “Supernova” for Linux, macOS, and Windows! With this year’s version, we’re delivering much more than just another yearly release. Supernova represents a modernized overhaul of the software – both visually and technically – while retaining the familiarity and flexibility you expect from Thunderbird. This is a massive release, and modernises this venerable e-mail client considerably. I can’t wait to test it out once it hits the Fedora repositories – I never liked Thunderbird all that much, but Supernova seems like something that suits me a little better, so I’m curious to see if it can pull me away from Geary. If you want to quickly gauge the changes to the user interface, the Thunderbird team made a very handy page for that.

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. A detailed technical explanation of why Windows’s memory management – and only Windows’s – is causing so many crashes for Firefox, as well as a solution they found to address the problem.

At the end of 2008, Firefox was flying high. Twenty percent of the 1.5 billion people online were using Mozilla’s browser to navigate the web. In Indonesia, Macedonia, and Slovenia, more than half of everyone going online was using Firefox. “Our market share in the regions above has been growing like crazy,” Ken Kovash, Mozilla’s president at the time, wrote in a blog post. Almost 15 years later, things aren’t so rosy. Across all devices, the browser has slid to less than 4 percent of the market—on mobile it’s a measly half a percent. “Looking back five years and looking at our market share and our own numbers that we publish, there’s no denying the decline,” says Selena Deckelmann, senior vice president of Firefox. Mozilla’s own statistics show a drop of around 30 million monthly active users from the start of 2019 to the start of 2022. “In the last couple years, what we’ve seen is actually a pretty substantial flattening,” Deckelmann adds. The decline and potential demise of Firefox is a massive problem that everybody seems to be kind of tiptoeing around, too afraid to acknowledge that if Firefox were indeed to disappear, we’d be royally screwed. We’d end up right back where we started 20 years ago, with Chrome being the new IE6, but with the big difference that Chrome isn’t bad enough yet for people to care. The situation is especially dire for the Linux world, and I feel like a lot of Linux users, developers, and distribution makers simply aren’t thinking about or preparing for a future where they can’t rely on Firefox anymore. Aside from Firefox, there really isn’t any browser out there that takes Linux seriously, and this is a big problem. Chrome is a disaster on Linux – it doesn’t even do something as basic as video acceleration unless you use one of the third party, custom maintained versions of Chromium, and, of course, it’s a vessel for Google’s advertising business. Things like the Gnome Browser or KDE’s Falkon can barely be taken seriously, and on top of that, are based on Apple’s WebKit, which isn’t a great position to be in either – and that’s it. There’s nothing else. The desktop Linux world is playing with fire by being so reliant on Firefox, and now that Firefox and Mozilla seem to be in some serious dire straits, I’m dumbfounded by the fact nobody seems to be at all preparing for what happens if Mozilla ever truly goes down.

In version 91 of Firefox, released on August 10th, Mozilla has reverse engineered the way Microsoft sets Edge as default in Windows 10, and enabled Firefox to quickly make itself the default. Before this change, Firefox users would be sent to the Settings part of Windows 10 to then have to select Firefox as a default browser and ignore Microsoft’s plea to keep Edge. Mozilla’s reverse engineering means you can now set Firefox as the default from within the browser, and it does all the work in the background with no additional prompts. This circumvents Microsoft’s anti-hijacking protections that the company built into Windows 10 to ensure malware couldn’t hijack default apps. Microsoft tells us this is not supported in Windows. Sadly, this does not work on Windows 11, where Microsoft is now forcing users to change the default handler for every individual file type a browser might use.

Roughly a year ago at Mozilla we started an effort to improve Firefox stability on Linux. This effort quickly became an example of good synergies between FOSS projects. Just a nice feelgood read about collaboration in the open source world – and if you use Firefox on Linux, like I do, this is already benefiting you greatly.
