Rated 5 out of 5 stars

This is such a time and nerve saver, especially with the popular Toolbar Buttons 1.0 extension, which adds a wagonload of extra buttons all on its own to make the dialog really confusing. Should be standard FF behaviour!

Many thanks for this excellent piece of work!

This review is for a previous version of the add-on (0.0.6.1-signed.1-signed).
