Mozilla yesterday released a beta of Firefox 7, putting the lighter-weight browser in front of a large number of users for the first time.

According to Mozilla, Firefox 7 uses significantly less memory than Firefox 4 through Firefox 6, cutting consumption by as much as 50%.

The savings come courtesy of a two-month-old project dubbed "MemShrink" designed to drive down Firefox's memory consumption and close "memory leaks," bugs that prevent memory from being released to the system when tabs are closed. Over time, those bugs can degrade the browser's performance, or in extreme cases, cause it to crash or lock up.
