Firefox, loved it for years & why I will never use it again
I used to truly love Firefox, for so very long. I was the kind of guy that would always urge others using different browser to switch to FireFox, if for nothing else so they could use uBlock Origin or 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 used it, I -usually- fairly briefly tried 10+ other browsers, Opera, Dillo, small obscure browsers, forks etc. None of them stuck for truly long term, except Firfox.
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 being some of the more recent and biggest ones. I can not in good conscience use it nor enjoy anymore. The trust is gone.
Some months ago I switched to Librefox. I could not be happier. They are not doing the bad, nor adding any AI, nor the privacy destroying things that FF has done and will continue to do, despite backlash. Librefox does listen to their community.
I do not see any downsides of any consequence, since Librewolf 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, "sanity", all while feeling good about using this browser. Still, to this day the blue icon looks a little wrong. But that is easily changed by using a custom icon.
Very happy with Librewolf, and I do have Brave as back up, which I quite 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. So it goes.
