I am running Firefox 11 on Windows 7 and it has been working fine. All of a sudden, it won't open. I removed it and did a clean install but it still won't open. Any suggestions?

Depending upon if you do or don't recieve an error message & what the crash reporter states, it could be several things. Your best option is to visit the KB article posted below on troubleshooting Firefox not starting, as I said depending on the message and crash reporter it will give you different solutions to attempt to fix.

After clean reinstalls, I finally installed an earlier version of Firefox (10) and it seems to work fine now. Perhaps there is something funky about Firefox 11?
