Best Screen Grab Tool for Firefox

As a UI Designer, I've explored many different options for capturing screen shots of websites. One common problem in most screen grab tools is that they fail to capture the entire contents of a web page. The solution: Screengrab for Firefox. This handy little add-on allows you to snap away directly within your favorite browser. You can do a copy or a save of a selection, visible window, or the complete page/frame.

Problem solved.
