Hi. I own an ASUS N61JV-X2 notebook PC. I am using Mozilla Firefox 4.0.1 for Microsoft Windows 7 Ultimate 64 bit. My laptop comes with two graphics cards: an Intel HD GPU and a nVIDIA GeForce GT 325M with 1 GB DDR3 VRAM GPU. It also comes with nVIDIA Optimus technology. I configured my nVIDIA Control Panel to make Mozilla Firefox utilize my nVIDIA GeForce GT 325M GPU when I launch the web browser.

Currently, it is not utilizing my nVIDIA GeForce GT 325M GPU. When I type in about:support, it lists my Intel HD Graphics as the GPU being used with both Direct2D Enabled and DirectWrited Enabled set to true and GPU Accelerated Windows showing 1/1 Direct3D 10.

This is not correct. It used to show my nVIDIA GeForce GT 325M GPU with 1 GB of VRAM.

I left a thread on the nVIDIA support forums, but no one has replied yet so I thought to contact Mozilla regarding this problem.

How do I enable Mozilla Firefox to use hardware acceleration so that it utilizes my nVIDIA GeForce GT 325M GPU again?

For the record, I did turn on use hardware acceleration when available under the Advanced tab within my Mozilla Firefox configuration settings.

I am having the same issue as wellwu with FF 4.0.1.

My computer is a Dell / Alienware MX11R3 with Nvidia GeForce GT 540m and Intel HD 3000 display adapters.

The issue does not occur with the Google Chrome browser. On Chrome the Nvidia drivers load automatically. WebGL works fine.

I am not sure how to find out if the Nvidia adapter is working on IE 9.

Anybody have any thoughts on this issue?

Same exact issue here. I'd love to use Firefox 4.x, but will hold off for now until this issue is fixed. I've tried to add firefox.exe to the NVIDIA control panel, but to no avail. Latest drivers are installed.
