I've been using the -ms switch to do my silent installs but just noticed that doing so does not set firefox as the default browser.

1) Can someone point me to a list of the different switches one can use?

2) Is there a switch I can add to my commandline that will set firefox as the default browser?

you can use a batch file to add the propper registry entries.

to do this search for the topic "registering file extensions unattended".

Thanks for the info man. I actually knew about this thread, but I was wondering if there isn't a switch I can use on the installer that would accomplish the same effect.

Unlike MS, the mozilla guys aren't rude, therefore they don't give you a piece of software which automatically takes over your pc.

Either drop them a request or use a method of importing the settings into the registry.

Whichever method you use to install will easily adapt to add the required settings.
