I just updated my display driver (Nvidia GTX 560 Ti) to the latest version (331.65) and whenever I try to open a website containing flash-material (Flash version 11.9), Firefox (version 25.0) freezes and throws me the "Stop Plugin"-Dialog.
Meanwhile the TaskManager tells me that 2 Flash processes are open, until I stop the plugin.
I tried disabling the hardware acceleration in Firefox, but it didn't help. I am using Windows 8 (64).
What should I do, to fix this?
