The Geekette Speaketh

I'm currently doing the mock-up of a new online system for my organization. Part of the work is to get screenshots of webpages to paste onto the use case documents. I used to have an application that could help me grab full shots of a page without having to hit the "print screen" button every so often and stitching up the images using Photoshop or GIMP. Unfortunately, it isn't free and is only available for MS Windows applications. Fortunately, I found a Firefox add-on that does exactly what I needed.
