Steps to reproduce:

Small Gif animated icons in the menu are loadet and should play on mouseover. 


Actual results:

Allready used Gif animations dont play from the begining. Insted they only show their last picture. 


Expected results:

Gif animations should start from the begining each time they are used.
Workes in Google Chrome, Safari and Edge but not in Firefox.
Endless Gif Animations as the fire should play endless as in Google Chrome, Safari and Edge.

There is a work around to load "new" gif files insted of using the onld one from the cache: onmouseover="javascript:document.images['bild'].src=image.gif?rand='+d.getTime();"
This is a truly ancient bug: bug 129986. I'm going to dupe this. Work is underway that should make it possible to fix this, but we're not there yet.

This is not a workaround I'd recommend. You're actually reloading the image *from the server* every time the user mouses over it. I would strongly consider encoding the animation as a video instead and using a <video> element.

Yes thanks but this wasnt there 12 years ago. I allways thought FF is not replaying gif animations on purpose to stop blinking advertisement but scince Adblock these days this is not an issue anymore. Yes may be the new HTML5 <video> element is better but also way more complicate. All the other browsers are doing fine with the old gifs. 

 <video width="32" height="24" autoplay>
  <source src="movie.mp4" type="video/mp4">
  <source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
