Rated 5 out of 5 stars

Love this extension, but as previous writer wrote; the close X button is missing as well for me... (25.0.1 + 1.2beta). Keep up the great work!

Edit: Installed the beta2! I can now release my deep breath :) Thanks Chris!

This review is for a previous version of the add-on (1.2beta.1-signed.1-signed). 

It should be fixed in beta2. That should show up automatically in a few hours/days or you can get it by clicking on "Version Information" and the Version 1.2beta link at the bottom of the add-ons page.
