I have a pretty hacky workaround for this. It seems to be working fine initially, but I'm guessing this will break something eventually. BACK UP YOUR PROFILE BEFORE TRYING THIS
cd ~/.mozilla/firefox mkdir screen1 mkdir screen2 # for bash shopt -s dotglob # for zsh setopt GLOB_DOTS cd screen1 ln -s ../<YOUR PROFILE>/* . rm .parentlock cd ../screen2 ln -s ../<YOUR PROFILE>/* . rm .parentlock >From a terminal on screen 1... firefox -P screen1 -new-instance >From a terminal on screen 2... firefox -P screen2 -new-instance Again, USE WITH CAUTION AND MAKE BACKUPS FIRST -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/78538 Title: Feature Request: Allow Firefox to work on multiple X11 screens To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/78538/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
