Mozilla has released Firefox 4 Beta 4, bringing two very interesting features to the table: Panorama (previously called Tab Candy) and Sync.
Panorama is a nifty visual tool that lets you overview all of your open tabs and group them into sets with a simple drag-and-drop interface. It’s activated via an icon at the right end of the bookmark bar, which takes you to your tab playground, where you can expand or delete your tab sets, create new ones and organize them around the canvas as you see fit.
I don’t see the need to organize my tabs in a way other than the default, but then again, I’m not an extreme tab user — I’ve seen people with 30+ tabs open at all times, and in such cases a feature like Panorama can come in handy.
