Are you one of those hyper-multitaskers (aka insane weirdos) who keeps a bazillion browser tabs open at once?

Here’s something for you, and for the tab-curious: Tab Candy, a new experimental feature in Firefox that groups tabs into topical clusters to improve your workflow. It’s made entirely with JavaScript and HTML.

Firefox creative lead Aza Raskin offers this synopsis:

With one keystroke Tab Candy shows an overview of all tabs to allow you to quickly locate and switch between them. Tab Candy also lets you group tabs to organize your work flow. You can create a group for your vacation, work, recipes, games and social sites, however it makes sense to you to group tabs. When you switch to a grouped tab only the relevant tabs are shown in the tab bar, which helps you focus on what you want.

Here’s a video of Tab Candy in action.

An Introduction to Firefox’s Tab Candy from Aza Raskin on Vimeo.

Tab Candy has been kicking around as a pre-release for a while, but it’s just now getting to the point where the Mozilla folks feel it’s ready to be tested by a wider audience.

If you want to try it out, head to Raskin’s site where you can download a TabCandy-enabled build of Firefox. Note that this isn’t an extension, it’s a bleeding-edge build of Firefox with Tab Candy built in, so plan accordingly.

There’s also an FAQ, and a feedback forum you can use to get answers or submit requests.
