I just switched back to Brave after using Firefox for a couple years. I switched away from Brave over the Manifest V3 thing but it turns out they're preserving compatibility with V2 extensions and their built-in shields have gotten pretty good at blocking most things without even needing uBO. I had lots of little issues with Firefox that are like known-issues that have been around for years or things I haven't been able to find solutions to, so I was glad to switch back. Brave isn't perfect either, but.
