No it does not. But it wouldn't, in light of Florian's explanation. What I am seeing is temporal aliasing and the effects of the half-size rendering.Firefox does support antialias:true. Some AMD GPUs are blacklisted for antialiasing on OSX. Maybe that's what you are running into? Does setting webgl.msaa-force=true make a difference?There is no anti-aliasing happening in Firefox 14 on OS X. Presumably this is because FF is not yet supporting the antialias: true attribute on the drawing buffer though it is not clear to me how FXAA and anti-alias: true play together.
