So much more useful than other tab-listing extensions I tried, and it works perfectly with Tree Style Tab

Clean & useful for bulk actions on a set of tabs, and also for just listing them all when many of them : when they get too short for their titles to be readable.
Would have given 4,5 stars if possible, because multi selection by Ctrl-click does not work. However, I also use this add-on as a nice complement to "Window Saver". So, 5 rather than 4.

Love that this app is back to the old functionality. LOVE IT. Being able to select and act on multiple tabs is essential and what makes firefox the best. 5 Stars!

It is working in Firefox 57+ :D

The tab list UI need update. It looks ugly. And it is difficult to understand that by dragging mouse multiple tab could be selected.

Dragging on tab list should invert the selection. Multiple tab should be selectable by holding shift and checking the checkbox.
