And those are just the outstanding bugs. In terms of performance, Firefox is still slower than Chrome. It still has more UI jank, even on Linux. The new plugin API still doesn't give extensions the same level of functionality that they had with the old API, despite years of promising otherwise. Its responses to interaction media queries are inconsistent, necessitating the creation of a test page [5] to determine what its actual responses are (W3C specifications? what are those?).
No, Firefox is not a top-tier browser. It's more privacy-preserving than Chrome, which is why I use it, but I will never claim that Firefox is a better browser.

EDIT:
better dump Android at this point anyway
Dump Android for what, exactly? An even more user-hostile platform, like iOS?No, most people should be using a dumbphone these days, at least until we hackers get our shit together enough that alternatives Librem/Pinephone are good enough.
This goes double for when Firefox OS was around : 7-9 years ago.
