Animate Images

A Firefox userscript: combine with image.animation_mode=none to play animated image formats (GIF & WebP) on click.

Supported userscript managers:

• FireMonkey (as of 2.72): yes.

• GreaseMonkey (as of 4.13): broken when using privacy.firstparty.isolate=true.

• Tampermonkey (as of 5.3.1):

  • Does not work on pages where JavaScript is disabled (e.g. with uBlock Origin).
  • Does not support @match <all_urls> in metadata block: you'll have to add a * entry to the "User includes" rules.
  • You'll also want to add a * entry to the "User domain whitelist" rules unless you fancy manually whitelisting every request to fetch an image.

• Violentmonkey (as of 2.28.0): yes.
