I exclusively use Firefox but there seem to be some major issues anytime i come back to the "app" I'll usually get a balck or white screen and no matter how much i wait it wont reload. So i have to kill it in the mutlitasking and open it again. Which loses where i was scrolled too. So im wondering if this is Firefox exclusive or if other browsers have the same issue?
I've so far had good experience on stock Opera, and Vivaldi.
Opera GX gave me problems where the browser interface would be layed over the app interface rather than just being hidden. Took up 30% of my screen real-estate for address bar and new tab buttons.
