I never felt the need to use a GUI for it, it’s very easy to use.

Also the site itself is ancient, searching for stuff sucks over there.

There is no benefit to using Firefox unless you really like uBlock Origin and will not consider another kind of adblocker.

Mozilla is just controlled opposition lead by the same greedy executives as Google anyway, using it won’t make a difference. It’s at best 3% market share won’t stop Google from pushing their crap to everyone else either.

Problems of the modern web in general cannot be solved by just another browser engine. What it really needs is simplification. A way to make it do what it does now but faster and in a way that is easier to implement, but I don’t see anyone doing that in the near future.
