No, mull is a fork of Firefox meant for android and developed by the divestOS team, while mullvad is a completely different fork, only for desktop atm and developed by mullvad (the VPN company)

they both focus on privacy and integrate Tor patches and modify some configs to better resist fingerprinting, but mullvad browser goes a step further with the tor integration, going as far as storing all data in RAM, so it deletes every cookie, history etc on restart. Could be an advantage, could be a disadvantage, up to you

what’s the fun in modding if not the two hours where you think you’ve bricked everything and you’re scrambling through a 52 page post on XDA trying to find someone with your same problem
