Rated 5 out of 5 stars

Very useful tool. One request though, would you please add the ability to change the toolbar icon

This review is for a previous version of the add-on (2.7.3.1-signed). 

I don't think there's any need to add such a thing. This is what userChrome.css was created for, so you can override the browser theme, and that includes icons and such in add-ons. However, this is *not* the place for support requests, since I have no proper way to contact you. Please get in touch by email or through the listed support site; then I will be glad to help you with this. Thanks.
