Rated 4 out of 5 stars

This addon is a great idea.
It can replace bookmarks.

There is one little annoyance - you can't middle click and open selected site in a new tab. Middle click doesn't work at all.
Other then that, I found this extension very useful and practical.
For sure will recommend it to my friends.

This review is for a previous version of the add-on (0.6.0).
