firefox got 3% browser marketshare these days, the only users left of it are those oldfags in stuck culture who cant accept chrome as their new religion.
thanks for rust but their overpaid management literally killed the brand.
email wise whats cumbersome with proton is it tries to upsell me again and again with its add-ons.
on google workspace i can say the best advantage is how almost 90% other sites out there supports signing in with google. and it's also cheap at $6 per head, and it doesnt harass you with upsells unlike proton.
