I went to Librefox. Apparently Waterfox sold out to an ad company (think not owned by them anymore but still).
LibreWolf is good but the anti fingerprinting makes sites uses light mode and you have to resize the browser window every time you open it. I installed dark reader to get back the dark mode so wasn’t a major issue. It’s a compromise you have to make for better privacy I guess.
The thing is if Firefox disappears then so does LibreWolf and Waterfox. LibreWolf is the way to go for now but the way Mozilla are going then who knows how long Firefox will last.
I gave Brave a try and I’m sticking with it. Yes it’s chromium. And it’s for a bunch of bloat like wallet, vpn, ai shit on it but I disabled it all. Brave is a lot faster and smoother than Firefox. Websites load up much quicker.
The built in adblocker is good. And the anti fingerprinting doesn’t break anything so I’m happy. I don’t know if I will stick with Brave long term but I can’t be bothered setting up a new browser again.
Waterfox's dev bought it back and went solo again, nothing to worry about there.
I had the same issues you did with LibreWolf, but I think I went too far following the guides. LW tells you how to go as far as you can with going to TOR, which is too much for most people's needs. The anti-fingerprinting for example: if you resize the window you lose that element, so it's pointless. I think base LW with the right extensions is fine for most users, but I can't be sure as I'd need to try an out of the box install to know.
I ended up switching back to FF with BetterFox, decent extensions, and NextDNS. Absolutely fine for me.
Of course you are free to choose as you wish, but to put it bluntly the doom and gloom about a potential future for Firefox isn't based on reality. Open source friendly devs would carry it on forever, it's got too strong a fan base to die off.
