|Yeah, we missed you, Firefox ;) Welcome back!|
What's new on Firefox 4?
Second: graphics it's rendered using DirectX (on Windows) of OpenGL (on Mac OS X and GNU/Linux)
This second feature means also Firefox can use the new WebGL standard.
I suggest you to give it a try if you passed to Safari/Chrome and you feel the lack of some extensions. You will have a surprise.
And a final joke: What did Firefox so far? The playmate? Errr...!
