Nice pause/play button overlay on each gif on hover, much better than having to interact with a dropdown menu from the toolbar only to disable all the gifs on a page at once and only after reloading the page! Great for reducing distractions. However, it would be more accurate to say it disables or hides the gif, perhaps just overlays the page/box background color overtop the gif, since it seems to continue to play invisibly rather than actually pausing at a specific frame. Not a huge downside, though in some specific cases it might be nice to be able to pause and play from specific frames, but that might be a limitation of the filetype that would have to be overcome by a not-so-light browser extension!
