Firefox for Android does not support Material UI, has a low minimum API level, and generally seems lacking in features. Why is that?
Edit 1: also the downloading function is super unstable, I lost several files due to firefox starting the download then stopping and removing the download for no reason.
Not OP, but the one thing that bugs me most is that Firefox Android does not have a tablet UI. Other browsers like Chrome have a tab bar and other desktop-like UI features when run on Android tablets.
But on phone I’ve never run into a case of wanting a feature that it lacks.
I’m in the same boat as you, but it seems that Mozilla is finally going to try to improve the tablet UI this year: https://www.androidpolice.com/firefox-tablet-ui-being-developed/
Edit: I went down the rabbit hole and enabled the tab strip in Firefox nightly and I can confirm that they already implemented a huge chunk of what’s needed for a proper tablet UI and IMO do it much better than Chrome.
