Rated 4 out of 5 stars

Tab Mix Plus does have this ability, but it does not have the ability to stop at the end of the list of tabs and not loop. Neither extension has the ability to have a hotkey that allows you to scroll between the tabs by pressing a key and NOT having to hover over the tab bars. That would make this a 5 star extension.

This review is for a previous version of the add-on (20080517).
