Just updated from 12.6 to 12.8 a few days ago. Suddenly my Firefox started having problems I've never had before. It normally uses about 400k memory, and 1-2% CPU max. Now, after it's been running a variable length of time, the CPU usage jumps to around 15% and the memory usage starts to climb - slowly at first and then faster and faster. When this happens, Firefox freezes. Eventually I either kill the process in the Task Manager, or Firefox dies on its own. FF 15.01, Windows 7 x64 with all updates, i7 950 processor, 5850 graphics card, 12GB memory.

Didn't see issues with anything else - only FF. Happened no matter what I tried, so I rolled the driver back to 12.6 and it's running fine again. Something is screwy with that 12.8 driver. Don't know what, but I'll wait and try 12.9.

There are several posts concerning this, please search and pay attention to hardware acceleration.

Cheers!
