My Firefox browser was working fine a few days ago, but lately my mouse is slow, jerky, and a pain in the butt. It only does it on Firefox, not anything else. My computer was actually crashing whenever it went to sleep for about 2 weeks now, but I figured that was a problem with Windows 7 (an unsolved problem at that). Just a minute ago my screen went black, then came back and a message about a NVIDIA driver popped up but I didn't have time to copy it. I uninstalled that driver since I didn't know what it was, but my mouse is still moving slow. In case it is relevant, I included the troubleshooting information from when my computer blue screens. THANK YOU so much for any help. == This happened == Every time Firefox opened == A few days ago.
