Youtube Embed: Controlos (Play/Pause and Fullscreen) does not show up in Firefox
I use the following embed code to embed a youtube video on my wordpress page:
<iframe width="100%" height="100%" src="http://www.youtube.com/embed/LjQtRr4CKcc? modestbranding=1& showinfo=0& rel=0& autohide=1& controls=1" frameborder="0" allowfullscreen></iframe>
In Chrome the controls for play/pause and fullscreen show up. However, in Firefox they don't. Still, if I know where to click, I can play/pause the video and also set it to fullscreen. So the functionality is there, but not the symbols...
Can anyone tell me what I need to change, in order to show the buttons in Firefox for embedded youtube videos?
UPDATE: interestingly, when I load the page in "private mode" of firefox, the buttons show up. UPDATE2: clearing the cache in firefox did the trick. So, obviously the issue was not the code, but my local firefox. Still, a friend of mine has the same issue, leading me to think that this is a strange issue..
It's a bug in FF44 (I read on mozilla forum). Will be fixed in v45 next month. You should embed the YouTube video with https:// not with http:// then FF will show the controls.
