Firefox, loved it for years & why I will never use it again
I used to truly love Firefox, for so very long. When people asked or were having a bad browser experience I was the kind of guy that would always urge others using different browsers to switch to FireFox, if for nothing else so they could use uBlock Origin or for a few other quality-of-life add-ons.
I used to loved the Mozilla foundation, the look, the customization and importantly, the relative privacy of their browser. Started on Netscape long before Firefox existed and even after I first used Firefox, I -usually- fairly briefly tried 10+ other browsers, Opera, Dillo, small obscure browsers, forks etc. None of them stuck for truly long term, except Firefox.
Yet Firefox has made so many bone-headed, anti-user & (Google) money motivated moves, of which adding AI and removing their promise to never sell data are some of the more recent and egregious ones. I can not in good conscience neither use nor enjoy it anymore. The trust is gone.
Some months ago I switched to Librefox. I could not be happier. They are adding AI, nor doing any of the bad and privacy destroying things that Firefox has done, and will continue to do, the despite backlash the faced. Librefox does listen to their community.
I do not see any downsides to Librewolf, since that is a Firefox fork. I can use all the add-ons I care about. I can make it look and work almost identical to Firefox and I get to keep very significantly more of my data, privacy and "sanity", all of that is by design and built-in. All while feeling good about using a browser not made for profit. Still, to this day the blue icon looks a little wrong. But that is easily changed by using a custom icon.
I do have Brave browser as a back up, which I rarely use or need. One day, if Ladybug becomes a viable alternative, I will likely install that too.
Many others seems to have switched away, or are considering it.
