I think firefox is generally fairly stable and not expected to crash your machine, do other things also cause the machine to crash?

At what point does the crash occur, do you get the firefox programme itself opening properly and the browser appearing. See Firefox hangs or is not responding - How to fix

Use firefox in Diagnose Firefox issues using Troubleshoot Mode and set it to open with a blank page as the home page. You could look at Firefox Crashes although that relates more to firefox itself crashing.

I am not a Windows 7, but presumably you have event logs which may give a clue as to what happens.

Firefox does not open fully. It opens to a white screen--no toolbars or anything load at all. And then everything freezes. I can't even do ctrl+alt+del.

The home page was set to Google...so it wasn't anything intense.

No other programs cause me to crash.

I've used Firefox for years, and never had this problem. My system is only a few months old, but I've never had a problem prior to yesterday with Firefox.

Did you try using safe mode with a blank page or a file from your local pc as the home page , maybe even with internet unplugged, does that still cause a crash ?

What is your event log showing ? does that give any clues ?
