You can start Firefox with parameters, but I'm having trouble finding a definite list of them.

What are some good parameters and what do they do?

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.
