Just a quick summary here at the end for anyone looking for an immediate answer:
This is not a bug; the documentation is just incomplete / unclear. If firefox is running already, you need to use slightly different commands from when it is not. Most of the docs assume you are not already running firefox. To create a profile when firefox is *not* already running, use "firefox -ProfileManager &". To create a profile when firefox is *already* running, use "firefox -ProfileManager -a blackmagic &". To start firefox with a profile when firefox is *not* already running, use "firefox -P <profile name> &". To start firefox with a profile when firefox is already running, use "firefox -no-remote -P <profile name> &". Example: I already have firefox running, showing this webpage. I want to create a new profile, so I open a terminal and enter firefox -ProfileManager -a blackmagic and create a profile called luser. I then run it by entering firefox -no-remote -P luser at the terminal. (I also created a launcher on my taskbar to do this without opening a terminal window) -- Difficult to find out how to use multiple profiles at the same time https://bugs.launchpad.net/bugs/31746 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
