Rated 5 out of 5 stars
Problem solved. As someone else pointed out, this extension does not work with Tiny Menu for some reason. I normally use Compact Menu anyway, so I uninstalled Tiny and installed Compact instead, and this extension now works fine.This review is for a previous version of the add-on (2.8). This user has a previous review of this add-on.
Now works with Tiny Menu
Version 2.8 is compatible with Tiny Menu.
