FOSS Lovers

That will be a very long talks because it depend to many things. Like 1 famous topic here; For sure, Firefox JS engine is less powerful than Chromium or support less. The question still, does everyone use everything in one go? Does site we visit use heavy JS? Does site use heavy tables or list? Multi layered DIV, Firefox legendary weak with this. Does site contain many moving medias? Again, Firefox weak with this. Chromium will throw all resources available to works on those. So does Firefox though. In the end, alot of resources will used by both anyway, depend on the site.
