Rated 3 out of 5 stars

Great plugin, but sorry those extras serve ad's they are adware, no matter how the developer tries to describe it
Great plugin does just what it says as far as screenshots. The ability to capture a whole web page even if it does not fit on your screen is great. Annotation tools are very handy.
In Safari the adware is still on by default.
Make up your own mind, pop over to the excellent thesafemac site and read their July 14 post about what they found when it was installed.
I would give this 5 stars if the removed the crap.

This review is for a previous version of the add-on (2.4.4.1-signed).
