It's working perfectly for me.

The add-on worked exactly as expected. All you have to do is right-click a GIF and it saves as exactly what you want: a GIF! Before I had this extension, I had to save images, which was annoying. It was so useful, easy for me, and I'll continue to use it again. I've already been using it on Chrome for a while, so I'm glad the Firefox version is available. Thank you for this wonderful add-on!
