If "the browser" != [Chromium], but [Chromium, Firefox, Safari, Ladybird, ...], then I'm pretty happy with that. I consider it's much better then having Windows, iOS or GApps-Libraries-For-Android as de facto standard OS.
Surely, my beloved Debian would be the much more perfect OS for everyone ;-)
Being one of the ZetaOffice (and LibreOffice) hackers, I use Firefox as my primary browser. And I really don't like using software only Google knows how to support (=> Chromium). Sometimes I even think about migrating to SeaMonkey
But for example, you unfortunately can't properly debug multi threaded WASM code in Firefox.
Have a look at the Firefox developer tools' debug tab with this page opened. And it will list the threads (web workers) named with some randomized UUID. Impossible as a daily development driver :-/
