Can I open a parallel Firefox, that operates separately?

Posted

I want to operate a version of Firefox for a specific online job. But I also need my original Firefox to continue. I would like it concurrently.

I think this is what you want;

Usage: C:\PROGRA~1\MOZILL~1\firefox.exe [ options ... ] [URL]

      where options include:
 -new-instance      Open new instance, not a new window in running instance.

You can add -no-remote to the command line to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously. *http://kb.mozillazine.org/Opening_a_new_instance_of_Firefox_with_another_profile *https://developer.mozilla.org/Mozilla/Multiple_Firefox_Profiles See also: *http://kb.mozillazine.org/Creating_a_new_Firefox_profile_on_windows *http://kb.mozillazine.org/Shortcut_to_a_specific_profile *http://kb.mozillazine.org/Using_multiple_profiles_-_Firefox
