Rated 2 out of 5 stars

This is an excellent extension to use with Firefox as new buttons can be added to the toolbar Customise option simply by selecting a link on the home page and installing them. However, the documentation is obscure for installing extra buttons for non-Firefox Mozilla applications such as Thunderbird, and installs from the home page automatically add the buttons to Firefox, not other applications. That is why I'm giving this a low rating for Thunderbird - it is not obvious just how to add pre-existing buttons to the application!

Laura, glad you like the extension. Sorry you had issues installing into Thunderbird. I believe we answered this question for you when you posted on the forum.

You are welcome to update the rating if you are so obliged. We will be adding that overlooked piece of documentation as time permits.
