I’ve been told about Mull and fennec, but what about:
(From what I understand)
- Firefox Focus: blocks trackers and erases browsing history
- Firefox Nightly: new updates every night
- Firefox Klar: german version of focus
- Iceraven Browser: 3rd party fork with more add ons
Mullvad is a fork/spin of Firefox. It’s basically just Firefox with their extension built in, and you could get the same effect with Firefox by installing their extension.
And they don’t have a mobile browser app, Firefox does, but unfortunately the Mullvad addon isn’t available for Android Firefox.
