Command line arguments

This also applies to Firefox and Thunderbird. However, some Mozilla Suite command line arguments may not work in Firefox or Thunderbird.

You can use command line arguments to bypass the Profile Manager and open a specific profile (if you have multiple profiles). You can also control how Mozilla Suite opens, which components open initially, and what the components do when they open.
