Rated 4 out of 5 stars

This doesn't have bookmarks synchroniztion. I have Zemanta which is much better than this one for local note taking. Switching to quickfox.

This review is for a previous version of the add-on (0.6.0.4). 

You can set up synchronization using Dropbox though ( www.dropbox.com - great tool in any case, by the way!)
