The wide-release version of Firefox 7 brings changes to the majority of Firefox users that the beta and Aurora channels have been playing with for some time. These include claims of significant gains in reducing memory use, "often 20 percent to 30 percent less, and sometimes as much as 50 percent less," a company representative wrote in a blog post based on work by Firefox developer Nicholas Nethercote.
These performance gains are the first public results of an internal Mozilla project called MemShrink, which, as the name implies, is about reducing the browser's system impact. Mozilla cited several specific areas of improvement in Firefox 7, including when the browser is kept open for long periods of time, when multiple tabs are open at once, and when the browser is used concurrently with other programs that also use a lot of memory. The company also noted that MemShrink was successful in part because of the rapid-release cycle that a vocal minority of Firefox users have been criticizing.

So far, it does use less memory than FF 6. Noticed a 40mb memory difference. Nice.
