Shooter

If you have been looking for a simple way to take screen grabs of webpages in their entirety, without having to use editing programs, Shooter is exactly what you need.

With this Firefox extension, you can capture an image of a whole webpage, no matter how big.

To do so, you just install the add-on, re-start the browser and click on the camera icon located at the bottom of the screen, you will then enter capture mode.

Shooter will show you the website that is currently active in the browser, and you can select the part you want to capture with the mouse, or leave it to capture the entire page.

The selected image will then be generated as a high quality PNG file, or as a JPG file in one of three different quality settings.
