Isn't part of the issue at hand that the extensibility of Firefox is deep, while that of Chrome is shallow(er)? I understand that deep extensibility isn't necessarily a cause for memory leaks, the ongoing inheritance of a community making use of that deep extensibility can limit Also, I personally haven't been exposed to any evidence regarding the existence of memory leaks in a Firefox install with no extensions. Many people have anecdotal evidence of their issues with memory leaks, but I never see a corresponding claim for having no extensions installed. Of course that point is also anecdotal.
