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.
Forks like Mull and Fennec technically have access to all avaliable plugins, but it a bit annoying to set up. I don’t know why they don’t add an option to enable adding all plugins, with a disclaimer that some of them might not function as intended on Android.
All of the plugins I’ve tried in Fennec have worked just fine.
