Screengrab Add-on for Firefox 2.x

I have been using the Screengrab extension in Firefox 1.5 all the time. What it does is to save a website as an image. Everything is saved in the process which means that the image can become really big. I love it because I think it is so much easier and better to save a website as an image instead of saving the htm files with all the other elements using Save Page As.
