JKM, I removed your sig. Don't even think about putting it back.

 

Can you minimize it to make the window (see how everything comes back to Windows) smaller???? Still displayed but smaller??

If so then hit F11 and tell me what happens.

 

HAHAHAHA, you're pretty funny. ..and this is why Firefox is supported by the biggest Internet companies on the planet? Like GOOGLE? I think your logic might be a bit skewed. What I can load in Firefox in less than a second, it takes IE 3-4 seconds to load. That in and of itself is enough for me. On top of that IE is STILL getting hammered with security issues so I'll stay with something that's built by people who can actually write some code.

 

I can , and I just tried it , and this is what happened:

before ( screen1) and after pressing F11 (screen2)

 

So it does know what full screen is. It took over the entire screen with F11.

I don't know what's wrong with it. Does your trusty IE do it also? No.
Any other apps not going into full screen?
You're gonna have to go through all of the firefox tabs and see if you find something that limits the screen size some how.

 

That's the thing, it was a fresh install , of everything , i have checked every tab i can think of... I'm wondering if the install got messed up somehow...

 

I have Firefox on 2 machines and SeaMonkey also developed by Mozilla on my office computer, I never use IE anymore.
