steps to reproduce: 1. Load https://addons-dev.allizom.org/en-US/firefox/users/edit 2. For the profile pic, upload an animated image expected behavior: We don't allow upload of animated images for icons/screenshots. Same rule should apply for user images. actual behavior: We allow users to upload animated images (even though the pic doesn't animate upon saving).
stripping the animation sounds like this is working as expected. People will update their pic if they aren't happy with it.
