Rated 4 out of 5 stars
Plase put the label in RIGHT-CLICK menu of the TABs, under the main labels like OPEN NEW and similar ... thanks !This review is for a previous version of the add-on (188.8.131.52-signed).
You should see Copy urls Expert menu in Tab Context Menu
If it is not there then some other addon may have been creating conflict. Write to me if you want more detailed instructions on how to resolve this. (My email address is on the right hand side as "Support E-mail")
