Tab Kit is a Firefox addon to make tabs radically more efficient through tab grouping, a vertical tab tree or multiple rows of tabs, and many other useful tweaks. See About for more details.

Tab Kit Support

I write Tab Kit for free in my own time, so while I read all feedback please excuse me for not being able to reply personally to every message - my time is better spent improving Tab Kit.

• If you have questions, try the FAQ (coming soon!)
• To offer or vote on suggestions go to UserVoice
• To report bugs or small tweaks use the issue tracker
• If all else fails you can post in Tab Kit's Mozillazine thread, but I'm afraid I can't guarantee a reply
