Mozilla yesterday patched 11 vulnerabilities in the desktop version of Firefox, as it upgraded the browser to version 7.

The company has batted a thousand so far in its rapid release schedule: Firefox 7 marks the third consecutive upgrade that Mozilla has met its every-six-week deadline for a new version of the browser.

Mozilla switched to the faster release tempo last March, when some wondered whether the open-source company — which has historically struggled to ship on time — would be able to make its milestones.

The biggest improvement to Firefox 7 is a reduction in memory use. Mozilla has previously claimed that the upgrade slashes memory consumption by as much as 50% .

“Firefox [7] manages memory more efficiently to deliver a nimble Web browsing experience,” Mozilla said Tuesday when it launched the new edition. “Users will notice Firefox is faster at opening new tabs, clicking on menu items and buttons on websites.”

Most users will see a 20%-to-30% reduction in memory usage compared to Firefox 4, Mozilla said, but in some situations that can climb to 50%.

In an accompanying blog post on the Firefox 7 memory changes, Mozilla said that Windows users will see the most benefit.

The company also claimed that the memory diet has boosted the browser’s performance, especially in scenarios where users have opened numerous tabs and leave Firefox running for long stretches.

Firefox has long been knocked as hogging memory, criticism that prompted Mozilla to kick off the “MemShrink” project , which was designed to drive down Firefox’s memory use and close “memory leaks” — bugs that prevent memory from being released to the system when tabs are closed.

Other changes that debuted in Firefox 7 included a new hardware acceleration framework to speed up HTML5 rendering, and an opt-in tool called Telemetry that lets users send performance data to Mozilla.

Firefox 7 also patched 11 security vulnerabilities, 10 of which were rated “critical,” the company’s most serious threat rating; the sole exception was labeled “moderate.”
