Well I will sound like an old bore but throughout the nearly 20 years Firefox is out I never looked at anything else. Seen the rise and fall of Internet Explorer seeing the rise and fall of chrome.
Even Firefox in its dreadfully slow era (2010-2016) it did not made me change. And let me be clear Firefox is far from perfect. But for my use cases (privacy and security balance over certain conveniences) I would not change for any commercially backed Browser.
Moral of the story. It's better to donate to Mozilla and enjoy the freedom of your browser than giving yourself in on the erratic behavior of the big tech companies.
They collect everything? I'm on mint. I want extensions, and not have to run my browser like I need to tweak an OS. I just want it to work. What do I use?
Just use Firefox and don’t worry too much about it. Tech people are a bit crazy about this stuff sometimes. It’s just telemetry going to the Mozilla Foundation, it’s not a huge deal IMO. If you really really care then use Librewolf but prepare to accept the trade off that some websites just don’t work sometimes.
DO donate to Mozilla as without them the Firefox, Tor, Mullvad, Floorp, Mull, Waterfox AND Librewolf browsers wouldn't exist.
Librewolf disables SafeBrowsing, which is a security must-have for anyone installing a browser for friends/family - and in many cases even for yourself.
