Public bug reported: You need a secret extra option if you want to run the Firefox profile manager.
Steps to repro: bash$ firefox -ProfileManager & Expected outcome: Profile manager dialog box Actual outcome: New Firefox browser window in your current default profile Workaround: bash$ firefox -u bugger -ProfileManager & The -u option is not visible e.g. in firefox --help output, but somehow it actually exists, and allows you to work around this problem (can't remember where I discovered it, Google no doubt?). I'm sorry if this is a duplicate, this problem has existed since basically forever but I was unable to find a report in Launchpad. bash$ lsb_release -rd Description: Ubuntu 12.04.3 LTS Release: 12.04 bash$ apt-cache policy firefox firefox: Installed: 24.0+build1-0ubuntu0.12.04.1 Candidate: 24.0+build1-0ubuntu0.12.04.1 Version table: *** 24.0+build1-0ubuntu0.12.04.1 0 500 http://security.ubuntu.com/ubuntu/ precise-security/main amd64 Packages 500 http://mirrors.nic.funet.fi/ubuntu/ precise-updates/main amd64 Packages 100 /var/lib/dpkg/status 23.0+build2-0ubuntu0.12.04.1 0 500 http://fi.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 11.0+build1-0ubuntu4 0 500 http://fi.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages ** Affects: firefox (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1226952 Title: Option -ProfileManager does not work without (bogus) -u Status in “firefox” package in Ubuntu: New Bug description: You need a secret extra option if you want to run the Firefox profile manager.
