Rated 5 out of 5 stars

Excellent. Since 78.* version and above, the extension provides a separate button, which has to be added from the toolbar customization.

This review is for a previous version of the add-on (6.0.4). 

From up 78.* the extension provides a separate button, which has to be added to the toolbar from the toolbars customization dialog. Read the descrition on the add-on page.
