This may not be a question as much as a feature request. But I was wondering if Firefox will ever have a way of grouping tabs (similar to grouping bookmarks in folders). I keep a lot of tabs open, such as forum topics that I refresh and watch constantly. It would help to be able to group them so they won't make the entire tab bar so long.

You could drag a tab over another to turn them into a group (and add more tabs by dragging them onto that group). One could then hover over the group to see the list of tabs in it. This would be very helpful, so I hope it may happen soon. Thank you.
