Rated 5 out of 5 stars

Excellent! Easy to use, easy to customize, great free basic use, has tags, searchable from my devices, computers; toolbar can be toggled between full toolbar to a single icon. The most used extension on my Firefox & also Google Chrome. I highly recommend Diigo.

Diigo is Great Rated 5 out of 5 stars

Love Diigo! Figured out how to eliminate the Diigo toolbar, while keeping Diigo functional, adding viewing space on computer screen.
