1 year agoyou can use a secondary firefox profile. starting firefox with the --no-remote -p
switches allows to load it alongside the main profile (-p loads the profile manager and --no-remote suppresses the “open new window in existing profile” behavior
at least java minecraft does that part right with the offline mode that switches off auth checks. for a real online server you need a login plugin then (makes sense that some form of username ownership verify is needed in that case) but for a secured LAN it is usable by default.
