Firefox on the Linux Desktop Service
Multiple Hosts
If you try running multiple versions of Firefox on different hosts with the same home directory, then Firefox will complain that:
“Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.”
To avoid this problem you need to have a different profile for each host that is running Firefox. You can start Firefox with the command
$ firefox -ProfileManager
This will allow you to choose an existing profile or create a new one.
Running Firefox Remotely
If you are connected to a remote computer via ssh (e.g. a node on the met-cluster) and you want to run Firefox on the there rather than use Firefox on your local computer then you’ll need to use the command
$ firefox -no-remote -ProfileManager
If you want to check which computer Firefox is running on, try opening the URL file:///etc/sysconfig/network or file://etc/hostname
Firefox refuses to start
If Firefox refuses to start try removing your profiles, which are located in your home directory.
$ rm -rf ~/.mozilla
