Many people, especially web developers, often need to capture all or part of their screen or all of a website as an image. This can be used for uploading proof of shipment when the post office loses your package, for showing people a bug or typo on a website that needs to be fixed, or anything else. Another feature that especially benefit developers is the ability to find the dimensions of any part of your screen. Google Chrome’s Developer Tools shows you the dimensions of highlighted elements. But, if you want to manually select a part of your screen and find its dimensions, a Firefox plugin called FireShot works very well. It also allows you to take screenshots and save the image to your computer or in your clipboard, among other options.
