Public bug reported: Firefox used to stop animations (like animated GIFs) when the escape key was pressed. This capability seems to be missing from recent versions of Firefox. Please restore it.
Currently there are some partial work-arounds by editing about:config's image.animation_mode which can have values of normal (default), once, none. However, none of those provide the functionality of being able to stop the animation on demand, whether after a fraction of a second or after a few minutes. What should happen is (barring changes to image.animation_mode) that Firefox should show the animation but then stop it if and when Escape is pressed.
