Firefox mobile isn't there yet. Passwords will conveniently autofill from your Google account thanks to the Android level implementation of password management, but more importantly it's resource heavy and bad UI design. Ublock support is nice but some websites just don't deal with it well. The nightly builds do fix my main problems with the UI but they crash all the time. So there's hope for the future, but for now it's not great unless you absolutely need proper browser level ad blocking rather than Blokada.

Tbh I switched to Firefox mobile from Chrome and have the opposite experience. While it is in someway less convenient for auto fill, as long as my Google account is logged in on another browser page I can always use it for that and they have password and credit card auto fill features should you want to take care of them.
