I use firefox on all devices, but there are two notches against it in my book:
Firefox on Android lags during scrolling on multiple sites that do not lag on Chrome. The only extension I have is UBO, and I don't know if that is the cause of it or not - I haven't tested thoroughly. One way or another there is a performance issue there by default.
Second, GrapheneOS has this to say about Firefox on mobile:
>Worst of all, Firefox does not have internal sandboxing on Android. This is despite the fact that Chromium semantic sandbox layer on Android is implemented via the OS isolatedProcess feature, which is a very easy to use boolean property for app service processes to provide strong isolation with only the ability to communicate with the app running them via the standard service API. Even in the desktop version, Firefox's sandbox is still substantially weaker (especially on Linux) and lacks full support for isolating sites from each other rather than only containing content as a whole. The sandbox has been gradually improving on the desktop but it isn't happening for their Android browser yet.
I'd love for both of these issues to be resolved at some point. But I stand by it because I like UBO and because I'm a bit contrarian.
I have never had any scrolling lag issues on Firefox (in the form of Fennec from F-Droid) on GrapheneOS.
Native Firefox on native Android (or at least the Samsung variant) here and I haven't had issues either.
I've had the issue on multiple phones. Firefox nightly seemed to fix it for a while but it suffers from it too after a while. I need to test if it's UBO or the sister comment that says closing tabs and restarting helps. It's only on certain sites I really notice it, maybe JS or video heavy sites. NYTimes in particular.

It starts to lag after a while on some sites but force-stopping occasionally fixes it for me.
Vanadium is a good browser but I wish it had Firefox's Private Mode toggle, for permanent private mode *
It's fiddly to even manually wipe history in Vanadium as it defaults to the '15 mins' option, and then it tries to suggest a subset of sites it thinks you want to retain data for **

** (Yes I know this is upstream behaviour.)
