Is there a command-line argument that would force firefox.exe to launch a new process for a particular URL regardless of whether another instance of firefox is already running?

You can open the command line interface by pressing Shift+F2.
To start the Profile Manager, type firefox.exe -P into a command window. Note: If Mozilla Firefox is started by Silk Test Workbench, an empty profile is used. This ensures that the test starts at a clean state. If the user manually starts Mozilla Firefox, the default profile is used.
You can use the -no-remote command line option to start a new Firefox process that is invisible to the first process. [1] By using -no-remote along with the -P option to select a different profile, you can open multiple instances of Firefox at the same time, using separate profiles.
You can close Firefox through the Terminal if it refuses to close through Firefox > Quit<br> You can open the Terminal by searching for it on the Spotlight (top right corner, magifying glass) Once open, you can run this command to kill the Firefox process: *kill -9 $(ps -x | grep firefox) I'm not a Mac user but that ...
If you have a second profile (like 'sidekick'), the following will launch a new Firefox process:
firefox.exe -no-remote -p sidekick
However, if that profile is already used by a current Firefox session, that will not work.
To create a new profile launch Firefox from the command line with the -P flag and create it.
firefox.exe -P
