UPDATE:Solution for future reference (By Weapon)
guys, it's a profile problem.
I've had the exact same problem before.
Somehow, Mozilla creates a new profile and abandons your old one, and that creates a couple of faults...
You need to find your Mozilla Profile directory and delete your old profile.
If you go to Tools and Error Console in Mozilla, you'll probably find the directory there along with the problem you're having.
The files may be hidden, so do the "View hidden files" thing, and search for somewhere in Documents and Settings.
My directory was; "C:\Documents and Settings\user\Application Data\Mozilla\Profiles\default" - so you should have something like that, or not.
That there had the folder/file I needed to delete, but I can't remember if I deleted the profile folder or a file inside it.
I think you delete the folder.
Next time you open up Mozilla again, it'll create a new profile and everything will be in order.
ORIGINAL QUESTION:Alright so yesterday I was browsing the web and I got the evil blue screen of death. No problem right? I restart the PC and when I open up Firefox, it opens up like this:

Notice it's not maximized (It always had been before) but it's not just when I first open the program it's whenever I open a link in a new window. I want every window I open to be maximized. CAN ANYBODY HELP.
And no I'm not maximizing ever freaking page that pops up.

Thanks,
Cam
