You guys can do whatever you want to "diversify" internet browsers, but the writings on the wall. Not only is the majority using Chrome, but all minorities other than Firefox are now derivatives of Chromium. The average tech illiterate consumer isn't going to say "You know what, this isn't right! We can't let Google take control as the dominant layout engine!". They want something relevant that performs well, and Firefox hasn't been relevant in years. Stop wasting your time and drop it. You're ancient browser will crumble just like Netscape, IE, and Mosaic.
Yes but this isn't an election, it's a choice of software. Regular people do not care enough about internet browser dominance. Software projects like these are largely supported by the size of their user space and corporate backing. Your voice will never be heard.
Most websites are already broken, due to anti-adblocking, newsletter signups, GDPR consent, etc. I don't really care if most websites requires Chrome, most websites are broken anyway.
Plus this is Firefox. It has been down this patch before, heck it was born in it.
