I like to use Diigo Toolbar Rated 5 out of 5 stars
Diigo toolbar is really great for daily internet users. Bookmarking, sharing, group and sidebar are best options in Diigo. I was using Delicious to get it done but Diigo is providing such a unique facility to save daily web surfing data with unique method and technology. Thanks to Diigo team!This review is for a previous version of the add-on (126.96.36.199.1-signed).
