So my Firefox has sort of died on me (the reason I haven't been on in 2-3 months. I'm so used to Firefox, I can't use any other browser for very long without wanting to shoot myself). I start it up and that goes fine, but when I try to browse the internet, all I have is a white screen. Absolutely nothing there. The toolbars and all that stuff up top is there, but the part of the window where the internet pages are displayed is just white. I don't even get that "Welcome to Firefox, may I take your order?" page when you first start it up. I've gone to Firefox.com and looked at the help page, but I've been unable to find something that helps me.

Firefox also appears to be unable to download updates automatically. I have do go to Firefox.com and do it manually, and a new version doesn't seem to fix the problem either.

So, anyone know how to fix my Firefox?
