Why does Firefox crash when my computer's idle?

Question

I'm using Firefox, but whenever I leave for a few minutes, and I come back, it always crashes. Is there a virus? Or something with the add-ons? It's the only one of my programs that crashes. Everything else is fine, except Firefox. I even tried re-installing it, but it still happens. Help?

By the way, it only happens on my user account. When I'm on the other one, it doesn't crash or anything.

I know they just released Firefox 3, its possible you have some extensions (add-ons) installed that are not compatible with the new version, or out of date.

Click tools, then add-ons.

In the new window hit the check for updates button, this will ensure all your add-ons are the latest version available.
