This option is used to open the image in new window. Means when you click on any image on a website then there are two three options like save image, view image etc but not always you want to save all images, in firefox I used to view the image first if it suits my requirement then save it. But when we click view image then it opens the image in the same window, which diverts your mind, so it’s better to open that image in new tab and think about it later. So if you want to see this image in new tab then this is a very helpful tool. You can find this option in the Context menu (Right-Click menu) whenever you right click on any image in the browser.
