Greetings again, did any of you Puppians know about this one?
https://mullvad.net/en/browser
It's another fork of Firefox that follows the ESR dev branch (in that way setting it apart from Librewolf, which follows the main dev branch), created in cooperation with the Tor Project to supposedly enhance privacy. Kinda like Tor without Tor, it instead promotes the Mullvad VPN service. I tried it last night with F96-CE_4 and it at least runs nicely, felt very smooth. Just download the official archive and unpack it somewhere, you're good to go. I for one will welcome another browser that doesn't whine about my use of the Root-privileges.
