Rated 5 out of 5 stars

This add-on is well thought through. You can freely choose where you want to have that button and turn it off in context menu if not needed there. Love the solution to place it at the far left of the tab bar. Now I use Tabberwocky combined with this. Unbeatable combination and not as bloated as Tab Mix Plus.

This review is for a previous version of the add-on (3.5.1).
