With our Web browsers becoming more and more like an OS -- or actually becoming an OS as with Chrome -- it's not surprising to see developers turning their eye toward features which provide a desktop-like experience. Over at Mozilla, they've been working away at TabCandy -- which offers a whole new way to manage your Firefox tabs.

TabCandy is a bit like a full-featured virtual desktop manager -- think of Web pages as applications and browser windows as desktops. Install TabCandy and a button is added to your Firefox toolbar. Click it, and you'll see a view like the one above. You can group tabs, label them, and move tabs between groups with a simple drag-and-drop.

The layout is totally customizable -- resize group boxes however you want and reposition them, and the thumbnails automatically resize and re-order themselves. You can also add a new tab to a group by clicking the icon in the bottom-left corner. Click a thumbnail, and the page zooms into the foreground.
