Mozilla will try to plug more memory leaks in Firefox with a new, aggressive approach that relies on weekly bug triage meetings, the company said last week.

"It's become increasingly clear over the last several months that we have a pretty pressing need to deal with increases in memory usage in Firefox," said Johnny Stenback, a Finnish developer who works for Mozilla, in a message on a company mailing list last Thursday. "Since we released [Firefox] 4 (and before, too), we've seen lots of reports about Firefox memory usage being higher than in older versions, and that Firefox memory usage is growing over time."

Microsoft (17.07 percent), AVG (15.63 percent), and Symantec (14.47 percent) were found to be the top three antivirus vendors in North America, according to the latest quarterly antivirus market share report released by OPSWAT. Microsoft increased its market share from OPSWAT's previous antivirus report to surpass Symantec and become the North American leader. AVG held steady in the second position, and Symantec fell to third.

Worldwide, the top three antivirus vendors detected were Avast (12.37 percent), AVG (12.37 percent), and Avira (12.29 percent). Microsoft was fourth (11.24 percent), followed by ESET Software (9.98 percent).

After 14 years, it'd be sad if Duke Nukem Forever didn't enter Chart-Track's UK All Formats chart in the top spot. So, hail to the king, baby. L.A. Noire graciously slipped only one spot into second, despite a 54 percent drop in sales.

We knew Rockstar's crime drama had a massive premiere, becoming the UK's fastest-selling new IP, but those debut numbers must have been massive to survive several large double-digit percentage sales declines the past few weeks and yet maintain such a high ranking. Rounding out the top three: Zumba Fitness, which only saw a 2 percent decline.

One app that has grown from an iPhone hit to a worldwide phenomenon is Rovio Mobile's Angry Birds. Whether you're a fan of knocking over pigs and structures by flinging birds, or go berserk when you hear the Angry Birds theme music, you have to admit that the popularity of what was originally a simple iOS game it pretty amazing.

Now T-Mobile is capitalizing on Angry Birds fever with a clever YouTube video titled Angry Birds Live.

For 24 hours on Wednesday, 400-plus Internet companies including Google,Facebook and Microsoft teamed up for a large-scale production test of the next-gen Internet protocol, IPv6. Organized by the Internet Society to raise awareness of the need for a global transition to the new Internet protocol, the test enabled participants to gather data about possible glitches.

The Internet has been running on IPv4 for years, and the pool of available IP addresses has dried up. In February, the Internet Corporation for Assigned Names and Numbers (ICANN) allocated the last of the unused numbers into registries. IPv4 addresses are 32 bits, which allows about 4 billion under the protocol.
