[Firefox only] Screengrab! is a Firefox plugin that allows you to do printscreen of the website you are currently viewing, regardless it’s a selection or the entire website (that includes those you don’t see in the lower fold). The plugin is light, and taking the fact that when it had to printscreen a website with long scrolling content, blogs for instance, it didn’t take me too long. Screengrab! outputs the screen capture in either .JPG or .PNG.

You’ll need a Firefox browser to see Screengrab! in action. Definitely a very useful tool for web designers, developers and bloggers.
