Yes, I've installed it half a year ago and tested for some time (couldn't switch due to lack of adblock). It is very cool, OneUI-like interface, dark theme, a lot of small improvements. But speed? It is fast, about the same as current trunk FF, maybe there are less or shorter animations but overall it feels exactly the same, maybe it is faster by few percents but I can't see it as a user without using benchmarks. Normal FF is fast on my phone.
PS: I just checked - uBlock is available in Preview, woohoo, I can try it more now :) . Strange that it is the only addon available in my app, no NoScript, Badger and HtttpsE there (latest version).
Thanks. I haven't downloaded it to check, but from the GitHub issue I mentioned above that repo just contains a copy of the official Mozilla .apk, which contains com.google.android.gms and com.google.firebase. So it's not so good for "de-Googling".
I'm a lot less interested in the mechanics of using F-Droid than I am in the no-malware guarantee that F-Droid effectively provides.
