firefox: Group your tabs feature: Automatically sort by domain?

Question

I'm using Firefox 8.0 and am enjoying the Group your tabs feature:

But I'm not always good at keeping it organized. I'm trying to find a way to automatically put certain domains in certain groups. Probably through a plug-in? All the tab related plug-ins just help cluster your tabs together and don't actually work with the "Group your tabs" feature (which is why I posted the picture, to avoid ambiguity, since grouping tabs can refer to a lot of things).

Thanks

This Firefox addon doesn't exactly do that but it's the closer I know from what you wish to accomplish, be aware this an experimental addon: Mozilla Labs: Prospector - Tab Focus

An addon that reduces tab clutter by extracting your current browsing session into a new Panorama group.

You may want to vote on this bug which would help you or file a new bug requesting a way to sort by domain.
