I mean they already have one, Gecko. And since they also made Servo, they took a lot of the good parts and incorporated it into Gecko, which led to the speed up (they parallelized a lot of the processes and started using people’s GPUs more).

And they have made Mozilla VPN and had it integrate with this this multi-account container add-on (addons.mozilla.org/…/multi-account-containers/) that lets you sandbox your internet browsing (like you can set up a google account container, a Facebook/Instagram container, a banking/finance container). So those have been privacy pluses in the years since Baker canned the Rust and Servo teams, blaming Covid-19 all while giving herself a raise. And Firefox seems to be competitive with Chrome in terms of speed of web rendering and whatnot: androidauthority.com/firefox-vs-chrome-which-web-…

And there’s just some simple things in Firefox by default, like clicking on a simple button to disable most of the javascript that’s janking everything up on a website and making it simple and readable, that just make it so much better than Chrome.
