Firefox startup parameters
The Firefox Knowledgebase talks about the command line parameters. Also there is additional information at the developer website.
Some of the ones I uses most often:
-
-ProfileManager- starts the Firefox Profile Manager -
-P "Profile Name"- starts Firefox using the specified profile. -
-safe-mode- starts Firefox in "Safe Mode" useful when extensions go awry. -
-no-remote- permits multiple instances of Firefox using separate profiles.
