Hi I'm using Firefox last version on my Ubuntu 14.04 system. I'm happy of it and I don't use other browser. I'm also use tinkercad.com to make my 3D model. I worked on this site up to past yesterday and yesterday it stopped to work due to WebGL problem. I tried to force WebGL on Firefor, but browser crash when I go on page with WebGl content. Graphic card and driver looks support WebGL. test done has been install Chromium and it works on tinkercad.com. I can only suppose that origin of the problem is in one update, but I'm not sure of which one is. I attach here the page with my browser state. All best MM
