This review is for a previous version of the add-on ( 

The most visited toolbar menu feature is already there. You just need to create a new toolbar menu of type history that sorts by visit count. Below are step by step instructions:

1. Right click the toolbar
2. Choose New Toolbar Menu from the context menu
3. Click the History tab
4. Type Most Visited as the title
5. Click the sort by visit count icon (this is the second icon from the left at the end of the Search textbox. It is half transparent so you may have trouble finding it.)
6. Save

As for the Ctrl+D shortcut, I will add an option to enable its original function in the next release.
