I'm trying to get webgl running on my firefox (v37.0.2) via software acceleration with mesa. I tried following the steps that have been stated in this article: http://www.binarytides.com/enable-webgl-firefox-ubuntu/
However, I am unable to find any parameter named 'webgl.osmesalib' in about:config section? Has this been removed (or renamed)? If yes, then how should I instruct firefox to use mesa's software acceleration for webGL?
