"Mozilla released the hotly-anticipated Firefox 7 two days ago. Does it deliver on the promise of speed and memory improvements? Does Firefox 7 have what it takes to dethrone current Web Browser Grand Prix champion, Google Chrome? Read on to find out!"

"Apparently, the browser boasts “vastly” improved memory usage and increased speed. In fact, the memory usage is said to be up to 50 percent better, although it’s “only” 20-30 percent better most of the time.  Considering Firefox’ reputation of a memory hog, this will surely come in handy.

"Official release day was August 16th and the way things are going the successor simply called Firefox 7 might launch as soon as September 27 2011. This is just some six weeks away and Mozilla blog has revealed that Firefox 7 uses less memory compared to Firefox 4, 5 or 6 and that on average it needs 20 to 30 percent less, and sometimes even 50 percent less. Naturally this means that Firefox 7 is faster and it should also be more stable. Firefox 8 also needs even less memory than Firefox 7, but the difference is not so dramatic.
