I personally have used mull exclusively in the past, but use Fennec currently.
Commenting here just to ask others: mull has been terrible since Android 14. Is that just for me? Pages not loading at all until cache is cleared every few minutes, its been completely unusable for me so i switched.
Nothing like that on their github or nothing. Im on a pixel8/grapheneOS
People dont hate on ubuntu cause its inherently bad. They hate on it because its a corporate distro and they do some questionable stuff sometimes. The OS runs fine.
Why not debian unstable? Its better than ubuntu in pretty much every way imo. Somewhat less user friendly i guess.
