Perhaps the most perfect google chrome plugin. There is also one for firefox. instead of zooming in one click on the photos on facebook, you can view photos on the mouse in their original size. more than one dictionary can open and close this plugin. If it is not used that much, you will regret it. so I don’t know.
Photo Zoom for Facebook, formerly FB Photo Zoom, is a simple, light-weight extension that integrates directly into Facebook so you can see the larger images of albums, profile images and more whenever you hover over an image!
