Does it's job but still has a few "flaw"s worth mention:- Please add better PNG compression, currently it's not very efficient- I wonder why the 'Annotate Your Screenshot' -page, that shows up after taking a screenshot of a webpage showing you the screenshot and letting you edit it, has content over the internet such as 'http://readict.com/promotion/ff/script-for-AW.js' and 'https://ssl.google-analytics.com/ga.js'

This review is for a previous version of the add-on (2.3.1).
