Firefox using wrong graphics card for hardware accleration

I just updated my Nvidia graphic card driver to 275.33 version..

But after the update, Firefox chose to use the Intel HD graphics card for hardware accleration instead of the Nvidia graphics card. i checked using about:support and it showed the Intel card being used instead

Is there any way to alert firefox to use the Nvidia card instead ?

Additional Info:
Nvidia GT 425M
Firefox 5

Thanks all

You should be able to select the Nvidia card in your Bios when you are booting your PC

Hmm I will try that soon =D.

On a sidenote, my laptop comes with Optimus Technology, does it play a part in the issue ? :huh:

Maybe I've never had a laptop, if you do make changes in the Bios make a note of any changes so you'll be able to revert back if needed
