Is there a massive difference between the two? Anything I should be wary of with either of them before I use it? I’m definitely privacy focused and have been trying out both but have been wondering if Vivaldi with uBlock Origin serves my purpose just as well as LibreWolf would.
one is based on Chromium and is not open source, the other is a Firefox fork and is open source. LibreWolf definitely focuses more on privacy with a more anti fingerprinting stuff.
Another good one I like is Floorp. The largest downside to me is the foxless icon, but other than that, it offers a bunch of UI customisation and has Mozilla’s telemetry stuff disabled by default. If you want something more privacy-focused and/or don’t like that there is no fox in the icon, go for LibreWolf (wolves are just as cool as foxes!)
