TooManyTabs (free/donationware) is for the power-browser who likes to keep many Firefox tabs open at once. Instead of keeping all those tabs active, which can eat up your computer's memory, TMT creates a sort of waiting area where tabs can sit--still visible, but using no memory.

Most of the time, vendors are fudging a bit when they tout ease of use, but Muvee's Reveal 8 ($80, watermarked demo) is truly the easiest movie production utility I've ever used. It doesn't offer quite the granular control that pros or aspiring pros will desire, but there are more editing functions than a first glance will divulge. And for the average user who just wants something good-looking in a hurry, it's more than powerful enough.

Victor Rodriguez wants to know why law enforcement agencies can't stop the criminals infecting our PCs.

Believe it or not, authorities do occasionally catch cybercriminals. Just last month, British detectives arrested two suspects who may have been involved with the ZeuS/Zbot Trojan.

Do you burn CDs or DVDs of your photos, your presentation, or your playlists? If so, and if you want your disc, its case and insert to have a slick, professional look, take a look at SureThing CD Labeler Deluxe ($25, 15-day free trial).

With all due respect to the affected holiday shoppers in Northern California, yesterday's distributed denial-of-service attack on Amazon, Wal-Mart, and other sites could've been much worse.

Twitter's acquisition of Mixer Labs , a service that helps developers build location-aware applications, shows that the company hopes to make location broadcasting an important part of its service. And the microblogging service isn't alone, either: Google is getting into location-based services with its work on Google Maps and features like My Location, and Facebook recently adjusted its privacy policy to make way for opt-in location-based features.

That's why I think 2010 will be a big year for location-based services. Sure, 2010 is likely to be all about tablets and the looming showdown between Google and Microsoft , but it may also be the year when people become more comfortable with broadcasting their location to the rest of the world.

DisplayLink Inc. has disclosed plans to ship a chip that enables video to run in "SuperSpeed" USB 3.0 standard devices in the second half of 2010, which would allow its use in consumer products as early as next Christmas.

At the International Consumer Electronics Show (CES) in Las Vegas next month, the semiconductor startup plans to demonstrate a USB 3.0 device running its chip that will transmit video at up to 4.8 gigabits-per-second, USB 3.0's maximum rate, said Dennis Crespo, executive vice-president of marketing and business development at DisplayLink.

It's that time of year again: the Northern American Aerospace Defense Command (NORAD) is partnering with Google to track Santa, so all the world's good boys and girls can follow along online. This is not just an opportunity for you and your kids to see how close Santa is to your house, but it's also a chance to teach your children a little something about the world.

After months of rumors, we still know very little about Apple's tablet device -- but that could change very soon. Apple is reportedly holding a media event in San Francisco on January 26, where the company is expected to make a major product announcement.

Reader Jenny sent me this impassioned plea: "I use Google Reader to keep up on my favorite blogs and sites. I clicked something and now the subscriptions list that was on the left side of the screen has disappeared! How do I get it back? Help!"

Have no fear, Jenny: I, too, use Google Reader, and I know exactly what happened. That subscriptions list you mention is part of Reader's sidebar, which is collapsible, meaning it can scoot out of the way to provide more room for reading (hardly necessary in these days of widescreen monitors).

Ever need some information you saw a while ago--and discover that's practically impossible to find now? You can save yourself some trouble in the future with this Firefox addon.

Vonage now offers an unlimited $24.99-a-month international calling plan for iPhone and BlackBerry users, the company said Wednesday. The new "Vonage World Mobile" VoIP service competes with a $12.95-a-month service from Skype.
