Glitches after graphics card upgrade

Question

After an unfortunate but brief fire in my GeForce GTX 570 graphics card, I was forced to upgrade to a GTX 660, which seems to have caused some odd issues with Firefox.
After the computer has been sleeping, the scroll button icon no longer functions (I can use the feature, but the icon doesn't show up), and typically another graphical issue will occur, such as the close buttons and top bar completely disappearing, or the tabs becoming completely transparent.
I've tried reinstalling Firefox twice, as well as resetting. I don't think that anything else was damaged in the fire, as the hard drives are separated from the rest of the components, and it does work. No other programs have these sort of issues.

Answer 1

That seems to have fixed the scroll button problem, and three times after I logged back in everything worked, but this last time, the scroll button worked but the close/minimize/maximize buttons were gone and the top bar was missing, the tabs were still there, but those were gone.
My graphics drivers are up to date, and no other programs seem to suffer from this issues.
If it's worth noting, the time it didn't work was after the computer had automatically gone to sleep, and Firefox was open on the screen. When it's worked, I've put the computer to sleep, and Firefox was minimized.
