The non-profit organisation, Mozilla, has laid out plans for the engineering behind Firefox, with the aim to make the browser spread even more of its workload between multiple processes.

Mozilla's Chris Blizzard mentions in a biog post: "What this means is that every release of Firefox will get faster, more stable and have better multi-Web page interactive performance even if it doesn't include support for multiple processes.
But we know that in order to get across some hurdles, we're going to need to invest in the multi-process model. That's what this post is about. Multi-process is not a panacea for any of these topics, but it does give us a leg Lip on some of the more systemic problems."
