I stopped using it 2 years ago because that's no longer true. Time and time again I was having to dig around for whatever new setting got created and defaulted to a bad setting for a bad reason (spoiler: they want money)
At that point what am I gaining by not using Chrome, Edge, or what I ultimately use now, which is Brave. At least with Brave I get useful features like having access to Tor for basic things, great cryptocurrency support, etc.
I am genuinely curious what settings this refers to. I have been using Firefox for years and years now and only the Pocket thing really comes to mind, and getting rid of the icons on the new tab page. Neither of those felt particularly egregious.
