Maybe I'm missing something, but on the latest version of Firefox on Mac, I don't see any video controls on animated GIFs after restarting the browser. For example, this site, www.easygifanimator.net/samples.php
Yep. I see now, I'll be releasing a new version adjusting this extension info for what it's really made to work with (html webm videos, not gifs (images)). It was my mistake, original dev included gifs to its info description, but it only works on video files. Have a nice day. :)
