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:
-P "Profile Name"
Command line arguments
Mozilla Developers Center:
Command Line Options
Sign up using Google
Sign up using Facebook
Sign up using Stack Exchange
