Firefox 31.0 has glitches and crashes constantly

more options

I recently updated Firefox to 31.0 and my NVIDIA GeForce Graphics card and I've been experiencing a lot of crashing. Sometimes the browser window will glitch and things will be black boxes and it looks as if the screen was rearranged. It tends to happen when I scroll over certain things like the x on a tab or over a link. It's difficult to explain but it's just acting worse than it used to. The crashing usually happens around when the glitching starts. Firefox freezes for a while and then crashes. It's been whenever the whole window turns black as if it's been corrupted. Anyone else have these issues?

Please disable Firefox's use of hardware acceleration as the first step in addressing what sounds like Firefox's incompatibility with your Nvidia drivers.

"3-bar" menu button (or Tools menu) > Options > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

This will take effect the next time you exit Firefox and start it up again.

There are some cases in which the setting won't stick. Please see the following article for suggestions on addressing that problem: How to fix preferences that won't save.
