MDN / browserSettings.imageAnimationBehavior

A object that can be used to change the way the browser handles animated images, such as GIFs.

The underlying value is a string that can take one of three values:

  • “normal”: the default. Play animated images as normal.

  • “none”: don’t animate images at all.

  • “once”: play the animation once.

Examples

Disable animated images:

browser.browserSettings.imageAnimationBehavior.set({ value: "none" });
