I notice this only on web apps that should be native android apps (progressive web apps they are called, I believe). Normal websites work almost always. Those that don't work typically don't support Firefox 's strict data protection mode (whatever that's called). I REALLY hate that. Companies become so lazy and hire the worst web developers that don't have any clue and no self-respect. I still keep using Firefox . Ultimately there's an alternative for everything and if a company doesn't want me as a visitor or customer, so be it.
