The FireShot add-on for Mozilla Firefox allows you to take a screen shot of either the visible area of the web page you’re viewing, or the entire page. It includes an editor to tweak the image after shooting. FireShot allows you to save the image to disk, send it by mail, open it in an external editor or just paste the shot to the clipboard.
The built-in editor is a bit too much in my opinion, weighing down the add-on, but it can be good to have in your Portable Firefox, when you don’t have your favorite image editor handy.
