After upgrading to Firefox 4, I went into the page https://demos.mozilla.org/en-US/ (no idea why...) and I got the message "Unfortunately, while your browser supports WebGL, your video drivers may be too old. To view any of the demos tagged with WebGL, try updating your drivers at NVIDIA, AMD, and Intel."
I have a PanP7 with a Graphics ATI Mobility Radeon HD 4570 Graphics with 512MB GDDR2 Memory. I was wondering whether or not I should really update my drivers. I thought that the update manager would suggest me to update if it was required, but this has not been the case. Any suggestions? In case I should update, any suggestion on how to do it?
