Earlier quoted context omitted.
I genuinely have no idea what "missing features" or incompatibilities keep people on Chrome compared to the benefits of uBlock just plain working better on Firefox.
Bookmarks, passwords, payment information, recent tabs, extensions... all synced with your Google account in Chrome. Firefox can't sync to your Google account. All that information is synced across the entire Google account system, to your Android phone, other Chrome browser instances and so on. Yes I know you could export your data from Google and pull it into Firefox's sync system, but that's a hurdle.
But everything you listed (apart from integrating with Google's servers) can be done with Firefox.
