You could use Stylish and something like: * { transition-delay: 0ms !important; transition-duration: 0ms !important; animation-delay: 0ms !important; animation-duration: 0ms !important; } I believe setting delay/duration to 0ms should still fire events for the animation/transition (unlike "animation/transition: none") which should avoid breaking anything that relies on those events.
