Rated 5 out of 5 stars

Works great! Currently using FF 3.5.3. I have been using this add-on for about 6 months. No problems with it. I now use Google Bookmarks for everything, instead of the built-in Firefox bookmarks. I can log in on any computer and use my bookmarks. The bookmarks are stored under your Google account as a Notebook category, so they can be managed from the Google Notebook interface. I like the way an entry can be put in more than one folder. I also like the simple slash-delimited folder hierarchy. Simple but effective.

This review is for a previous version of the add-on (0.3.7).
