I play a game on Facebook - and i go to it from a link in my email - but today it says your browser does not support WebGL - this happened a month ago but I forget how it got fixed. :-( it worked yesterday - and I checked for Firefox updates and it is up to date. last time this happened - I did read an article online that suggested to go to put about:support in the address window and under General it said to uncheck standard performance and to click on "use accelerated performance" - that fixed it. This time when I go to about:support - "Use Hardware acceleration when available" is already checked. How do I fix it this time? and why does this keep happening every so often?
