It's already too late. Google has a monopoly on the browser market. Do you think your regular normie would continue to use Firefox if Netflix, Instagram, TokTok etc. don't work anymore?
There is nothing we can do. The internet of old is already lost.
I tried only Jerboa and that's what I stuck with. It loads fast and has every feature I want. Compare that to the official Reddit app, which is a slog on even high end devices. Seriously, what are they doing that it loads SO SLOW?
