Any luck?Also got this the last few days. It's annoying but haven't had a chance to try and get rid of it. On Chrome.
For real?
Does nobody else have this problem?
Is this a dream?
Any luck?
I discovered this problem at the same time you did on my own website (http://www.GoOutsideBook.com/). I fixed it by adding a parameter to the code the embeds the YouTube video (http://stackoverflow.com/questions/27723423/youtube-iframe-embed-full-screen). I'm guessing that browsers previously enabled full screen by default and now they don't - not sure why it would have changed. If I'm right, it's up to all the website owners to explicitly enable that feature, which could take a while.
