First look: Firefox 7 slashes memory usage

Mozilla?s Firefox 7 cuts memory usage and adds new tools for developer
  • 1 of 9

Mozilla debuted Firefox 7 just six weeks after Firefox 6, thanks to its rapid release cycl e. 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.

Among the changes for web developers in Firefox 7 are: upgraded support for web sockets; support for the Navigation Timing spec, which lets developers monitor parts of web page performance in the page itself; and a faster Canvas element. The new release also fixes some stability issues and incorporates a number of bug fixes. A new opt-in tool lets users send anonymous performance data to Mozilla, which is aimed at helping developers isolate places where Firefox is slow.
