fixed that for you
CSS scroll drive animation (standard), Cross document view transitions (standard), CSS corner shape, Multicol Level 2 (standard), some of the Filesystem Access API, WebGPU on linux, PWA manifest install (standard), took 3 years to ship documentPictureInPicture.
Facts are facts. Web standard are implemented first in chromium, then in firefox after years.
what?
Chromium based browser have strict multiprocess isolation. This is not true for firefox. If a tab crashes chrome it does not crash the entire browser. This is only partially true for firefox
yes it is a known fact that google sites including youtube are engineered to be slower on firefox.
Yes, and if you check browser performance on a neutral benchmark like speedometer 3.1 chrome is still faster. Also this is a fact.
Chromium is an objectively slightly better browser on paper than Firefox. Firefox is a much better browser for your privacy, for open source development and the health of the web in general.





You are just moving the goalpost. What I have said remain true, and I have never ever said you should choose a browser because of animation support (WebGPU is definitely not a small one, Multicol missing would break the entire website).
If there is any technical aspect (not moral, just technical) I am ignoring please feel free to share with the rest.
