I've been reading about Multi-Core support in Firefox. There are outdated Wiki pages. Which states "Firefox should be Multi-Core aware in 2 years", which is now. So I am wondering if Firefox 4, for the Desktop, is optimized for Multi-Core?

Short answer: No. Firefox doesn't have any specific ways of utilising multi-core, although I imagine that this isn't a significant problem for most usage scenarios these days, it might be more important in the future.

Robert O' Callahan has blogged about this a bit before:,

Or I recommend the WaterFox Project (Firefox with MMX, SSE2 and x64 favoring enabled)
