Yeah, I am going by the complaints from users in the Play Store ratings. It is pretty clear that the number is not big (the score on Firefox is still pretty high), but the complaints are very focal saying "this is the worst update ever".
> but most users are probably pretty satisfied with the update
And yeah, this one I don't have any backup, this is why I said "probably".
Even if the number there is small (which I'm not sure, "small" compared to what?), you can't look at one place and make such a global strong statement. There are many other places for people to voice their opinion, Mozilla forums, chat, social media or, well, here.

Probably is not a synonym of "maybe" or of "I don't know"...
You can read the reviews of the latest version in play store...
