Oh, there’s more than that. A lot more. Just one example: ublock and such firewalls weren’t effective for long, because on browser startup it does not hold back network requests while the filter lists of addons haven’t loaded yet. But as you probably know, in recent years google has been working hard to reduce filtering capabilities of addons to the ground.

To me there’s still a lot of reasons to keep Firefox, but actually instead these are just reasons to never install chrome, and never support it for friends (because it can’t be supported, because it does not even try to serve the user’s interest, because it is not a useragent, as it is technically called, but a corporate agent)

Yeah, totally the same. I’m only using it because that’s the only option, I’ll never use a chromium based browser, because that engine directly contradicts my my values. But the CEOs pay very much bothers me too, she does not deserve it at all, that money should be spent on useful work on the browser.
I have been thinking it for long that it’s not a good browser, but the one that is the minimally bad. Of course I don’t tell this to people when I try to get them to switch, because for them it does not send the message I actually wanted.
