To run the Firefox web browser from the command line in Linux, simply open a terminal window and type “firefox” and hit enter. If the Firefox application is installed in a location that is not in your PATH, you will need to specify the full path to the binary, like this:
/path/to/firefox
You can also run Firefox with different profiles by using the “-P” or “–ProfileManager” option:
firefox -P
This will open the Firefox Profile Manager, where you can create, manage, and switch between different Firefox profiles.
