How to open unique, per-user instance of firefox in linux through command line?

In my team, multiple people use same account on linux based server. If one user already opened firefox and others try to open firefox, it the throws the following error:

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.

I need something like $ spyder --new-instance to create new instance of spyder.

OS : centOS 7

firefox version : Mozilla Firefox 68.4.1esr

Solution

  • From mozilla website I found command line to open new instance, not a new window in running instance, which allows multiple copies of application to be open at a time. It is

    firefox -new-instance -P "Another Profile"

    Then create new profile > start firefox.

    Note: It is not available for Windows(bug 855899 for Windows has been fixed in 2019)
