The Mozilla Corporation is for profit, but they reinvest all of their profits. They are also wholly owned by the Foundation. You can't donate to Firefox.
Somehow it's always the lead software in a category that becomes shitty while everything else is praised. Regardless of what's being talked about. (I know why)
People get used to it, it's "fine" but doesn't improve considerably or add anything exciting, so people get bored. I moved from Firefox to Chrome, and honestly Chrome feels smoother and uses less ram seemingly for me on my laptop. Aside from no support for vaapi on wayland, chrome is fine imo
Once you finish setting up and are happy, if you care about privacy and don't mind a little more upfront work, set up Multi account tabs. It "sandboxes" your logins and cookies to categories you choose. I have a category for each social media site, one for my finances, one for amazon, one for other shopping, etc.
I live by, "never do anything you don't have to." But seriously I have some things customized in Chrome I'd have to adapt to Firefox. It would take a little effort on my part and I just don't want to deal with it until I have to. I'm sure it will happen sooner than later. I think the deprecation of Manifest V2 is going to force it because my browser is essentially a uBO support system. Until then I'll keep slogging along.
Have you tried Brave? Idk the full story, but it is basically chrome with more privacy stuff and is way faster than normal chrome. Feels just like using chrome but faster.
