Every web designer pushes the “Print Screen” button few times a day to work on the screenshot or just to find the color codes of a specific area.
When the whole webpage screenshot is needed “Print Screen” may not be enough.
Screengrab! is a Firefox plugin which helps you to get the entire page screenshot (visible area or selected area too), copy it to clipboard or directly save it.
It saves you so much time once you get used to it. You don’t need to plan for the perfect screenshot all the time, just get the whole and play with it using your image editing software.
