Hi - I have the same problem since a while and getting more and more site with embedded videos or link to GIF (e.g. as mentioned in other posts, connected to Twitter) not working. As well often, the same message, my browser doesn't support playing video, etc... What makes me frustrated is that, everything works like a charm when using Firefox! Here is a link to a page showing one of the problems ( Ce navigateur ne prend pas en charge la lecture vidéo) http://www.lequipe.fr/Football/Act
