Using FireShot, you can capture the page’s visible portion or the entire page. You can save the output image as a PNG, GIF, JPEG, or BMP file. You can also send the image to a printer, copy it to the clipboard, add it to an email, or even edit the image with FireShot’s external editor. FireShot has lots of features, but these can be a bit overwhelming if you’re just looking for Add-on that takes screenshots.
Although FireShot works well, I have two issues with this screenshot Add-on. First, there’s a “Check PC for errors” option at the bottom of the tool’s dropdown menu. Clicking this link immediately prompts you to download RegistryBooster from Uniblue. I understand FireShot’s developer wanting to make a profit, but this is a bad way to go about it. At the very least, the link should take you to the RegistryBooster web site and not prompt you to down the application’s EXE file. Second, FireShot is only available for Windows.
