I still have a few small gripes, of course. It feels fast and light and I may just make it my default browser again once the stable version comes around. I’ve been using the nightly version of Firefox for a few weeks now, leading up to this release, and the difference between these new versions and the old Firefox is night and day. Firefox Quantum also features a built-in screenshotting tool and a distraction-free reading mode. I appreciate that because I’m a heavy Pocket user, but not everybody is happy about this decision.

Like before, Mozilla continues to ship Firefox with built-in support for Pocket. Like previous versions, you can still modify the interface to your heart’s desire, but that interface will now also look good on high-DPI screens and work better on laptops with touchscreens. The new interface focuses on simplicity and speed. This means that the rounded tabs are gone, for example. The team also used this release to introduce a new interface. Ideally, this also means Firefox now uses far less memory (and often this means it’ll actually use less memory than Chrome).

This means that, unlike previous versions, Firefox Quantum can now take full advantage of multiple CPU cores - especially when it comes to its CSS engine, which plays a major role in how fast a web page renders. Servo was never meant to be released as a standalone project, but was basically the incubation chamber for the future of Firefox. That engine was written in Rust, a programming language Mozilla developed for exactly this kind of use case.

Many of the updates in Quantum come from Mozilla’s experimental Servo browser and engine.

Building these took longer than expected (and maybe necessary), but with Quantum, Mozilla now offers a browser that’s worth installing again. Over the course of the last few years, Mozilla’s engineers were hard at work on a couple of projects that are now finally coming to fruition. What matters is that Mozilla seems to have found its groove and focus again - and it’s starting to show. The organization also got caught up in some political turmoil and it took a while for it to recover from all of this. It’s no secret that Mozilla squandered a lot of time and energy on various projects that went nowhere (think its mobile phone OS, IoT services, creating a built-in video chat service, etc.).
