Future of tabs Rated 4 out of 5 stars
I think this is where the future of tabbed browsing is heading. This is a fantastic add on, and it has been considered as an included part of major firefox releases. The hibernation feature looks quite promising as well.
I have only one suggestion right now for an improvement to make to this extension. Could you make is possible to multiple select tabs so that they can be dragged and dropped into a new group at once? This goes along with the main reason I installed this add-on, which is because I wanted a way to organize my tabs when there were a lot open. It can be cumbersome clicking and dragging them one-by-one into a new group. Thank you for your high involvement and responsiveness with regard to your add-on, a definite developer plus!
It has been implemented
It has been implemented by the latest version under development.
You can select two or more tabs, and you can move it to new Group by dragging tabs to GroupBar.
For that, you need that you use it together with add-on of "Multiple Tab Handler".
