MB 75: Use Mullvad name (fix for mozconfig-linux-x86_64-dev)
requested to merge pierov/mullvad-browser:75-mb-fix-mozconfig into privacy-browser-102.8.0esr-12.0-1
I had lost one final pb- in the previous MR, and tested only in mullvad-browser-build tor-browser-build-s131, so I didn't catch it either.
