WebGL not working
I recently noticed that WebGL no longer works for me in Firefox, even though it has worked in the past. I'm currently running Firefox 14.0a1 Nightly on Window 7 64-bit (although I have also tried it in FF11). When I opened, up about:support, it said "Blocked for your graphics card because of unresolved driver issues.", even though I have the latest driver for my NVIDIA GeForce GT 540M GPU. I also haven't touched anything related to WebGL in about:config.
I've heard that Firefox doesn't play nice with Optimus. Could it be that, possibly? Should I update my Intel Graphics driver?

Sorry I do not know the answer. I do note another thread suggested changing prefs to remove a similar block.

If the user has a blocked driver, then open: about:config Then double click on: webgl.force-enabled=false This will change it to: webgl.force-enabled=true
Restart Firefox and WebGL will work.
I also note there was a regression causing problems with NVIDA & some 3Dgraphics, but the problem seems to have been resolved: 3D videos do not work with certain NVIDIA drivers in Firefox 11

It is worth trying updating drivers. Is the problem only with WebGL ? When did it last work,and does it work in the firefox Releaseversion Fireox 11.
I've updated both of my GPU drivers, and the problem persists. Yes, it seems to only be with WebGL. I don't remember exactly when it last worked, probably a few months ago, but I just recently noticed. It doesn't work in the stable release, either.

That did seem to fix it, thank you very much!
Glad it worked, thanks for posting back. I have only recently started using a PC capable of WebGL so do not know much about it myself.
