Rated 4 out of 5 stars

Thanks for updating Addressbook Tab. I find this much handier. Not sure why TB doesn't include it.
However, the plugin needs work. The upper right button opens a blank tab. Tools, Add-on Options opens it properly but this is less than obvious. It remembers its prior open state but moves position to prior to Lightening. It should remember its tab position too.
But I appreciate having it.

This review is for a previous version of the add-on (2.0). 

"Tools, Add-on Options opens it properly"

This is a special feature of TB from version 68.
I have pointed out this procedure specifically and clearly.
