Excelent! Noté 5 sur 5 étoiles
Exactly the type of addon I like - very simple with intuitive, quiet, but at-hand and ergonomic UI, which does EXACTLY what it promises to do.
May be just one thing to make it ABSOLUTELY perfect - please add "one frame forward" and "one frame back" button for paused GIFs for those occasions when you want to have a close look on one particular moment inside the animation.
Thank you for the kind words - that's precisely the feeling I was aiming for. I agree that "frame forward"/"frame backward" buttons would be fantastic to have, but unfortunately the Firefox API I'm using for this doesn't provide that functionality. :(
