Mozilla has released of the next version of its Firefox browser with better memory management and significant speed improvements.
"Firefox 15 prevents most memory leaks caused by add-ons, including Firebug," Nicholas Nethercote writes in a Mozilla blog. Firebug is a Firefox add-on for debugging web pages.
"For many users with add-ons installed, this will significantly reduce Firefox's memory consumption, without requiring upgrades to those add-ons," he adds. "For those users, Firefox 15 is likely to be faster (sometimes drastically so) and less likely to crash, especially if they have multiple add-ons installed and/or keep Firefox running for a long time between restarts."
Nethercote explains that add-on memory leaks are caused by "zombie compartments," where information from web pages is stored and remains after you close a page or depart from it.
Firefox 15 cleans out those compartments, a move that its developers weren't entirely sure would work.
