Desktop runs great, but Firefox on Android seems to be noticeably buggy here and there sadly. I still use it, but I can imagine that might drive people out of the ecosystem.
Many people get used to the synchronization of their passwords / bookmarks cross-channel. More advanced users have a separate password management for this I’d figure, but that’s not the default for 90% I’d guess.
I’ve never had a single issue with Firefox for Android and I’ve run it on all my phones for like 6-7years at least, probably more but I don’t remember.
It doesn’t play super nice with foldable phones. The UI doesn’t adapt correctly without restarting the app and you end up with a very dense interface of overlapping buttons if you try going from open to closed. The address bar becomes completely blocked by all the extra buttons from the tablet layout, so the app is unusable.
