This add-on fills a need I have to capture only part of a screen as opposed to the entire screen. Simple to use and very intuitive. I highly recommend this add-on.

excelent

very good

Truly great, capture selection, capture whole pages, copy to clipboard or export to pdf or jpeg.
Only thing it cannot do is capture those floating windows within windows (like for example facebook picture that you open when you click on the picture in the home page so it hovers above the home page. It would captue the homepage behind the floating windows. So for that I use prntscr)
But all else, this one is the best so far.

This Add-On works pretty good and does exactly what is advertised...it makes screenshots ;)

A nearly perfect tool for capturing images and full pages from the web. The only way to improve it would be to add a save to ebook format.

outstanding add-on. Saved me hundreds of hours in getting snapshots. Thanks. Bravo !!

Great addon with really useful options.

Wonderful add-on that helps me to document the corresponding results when doing research on the net.
