Rated 5 out of 5 stars

If I am not mistaken this extension had a button that could be placed in the menu bar. This is no longer available. Now if/when I want to open a previously closed tab, I have to click on tools -> session manager -> reopen closed .. then choose which window I want to open.
Could you put the button back, Please. Makes it a LOT easier/faster.

I normally have between 8 - 14 tabs open at anyone time. So the button is very useful. Thanks.

This review is for a previous version of the add-on (0.4). 

You are mistaken Session Manager with Tab Session History (this extension).
