There was a maintained Firefox containers extension that worked well for me. Even logged into sites would be fooled that it was not me logging in with my username/password and 2nd factor. It is no longer maintained. Their solution was to use Chrome. Someone mentioned yesterday using the extension which clicks all advertisements. There is a long list of anti fingerprinting extensions.
