Rated 5 out of 5 stars

A very nice add-on. Much needed when you visit the same pages again and again.

strongest features:
1. central management of all notes
2. ability to customize the url associated with a note using wildcard-like options.

weakest feature: very limited editor

Bug: You experience odd effects when you put your mouse over a link in bookmarks toolbar while being in pages having notes.

Suggestions for further improvement:
1. Enhanced Editor.
2. Ability to add pictures as notes.

Workaround: It may be really slow to scroll down pages having notes. Disabling smooth scrolling (Tools>Options>General>Browsing) fixes the problem

This review is for a previous version of the add-on (3.0.1.1-signed.1-signed).
