First look at Firefox 7

Mozilla cuts memory usage and adds new tools for developers


Mozilla debuted Firefox 7 just six weeks after Firefox 6, thanks to its rapid release cycle. One of the most significant improvements is a reduction in memory use, by as much as 50% in some cases, Mozilla claims. Users who keep lots of tabs open and leave their browser running for long periods of time will reap the benefits of Mozilla's MemShrink project, which is dedicated to improving Firefox's speed and stability by reducing its memory usage.
