Firefox, despite that some HN'ers bash them for not being perfect. And there is an occasional reCaptcha time-waster as "encouragement" from Google to switch.
Ungoogled Chromium, if you don't mind supporting the monopoly, and the (IMO) onerous upgrade path.
There's quite a difference between "not being perfect" and the continuous letdown and disappointment that is Mozilla management / decision making.
Mozilla just shattered an extension ecosystem and now there's like 10 extensions left. You can do store extensions in Nightly, but you now need a firefox account to do so. (And you have to press secret invisible buttons, not joking.) Non-store extensions are apparently canceled.
It's a power grab all the way down. We wouldn't make excuses if Google did that and we shouldn't make excuses if Mozilla does it.
Current Mozilla does not behave in a way that would demonstrate that they are a good steward for Firefox or the open web.
Dissenter is a version of Brave with all the BAT stuff taken out.
(Yes, Dissenter is associated with bad people. No, I am not one of those bad people, I just use the browser. Yes, it is sad that this disclaimer needs to be written. Please don't downvote me.)
