recently I upgraded to firefox 12. as soon as I did the screen constantly flickers when scrolling, mousing over anything, page updating, and especially streaming video flickers even worse. I tried downgrading to a previous version of firefox (10.0.2) but it still happens. I have used firefox for years and would like to continue to use it but this will give me a headache! PLEASE how can I fix this!

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

the new versions of firefox use hardware acceleration, please update the graphics drivers for your system for the feature to work properly.

for your integrated intel hardware see:

for the dedicated nvidia card:

in case an update of the drivers does not help, you can also switch off hardware acceleration in firefox > options > advanced > general

My drivers are up to date and I have a fairly robust graphics card (NVIDIA GeForce GTS 450). My card was top of the line when I first experienced the issue. The latest driver is installed today. This problem has been happening for over 2 years, but I still have to turn off hardware acceleration to be able to use Firefox.
