After a Firefox update, somewhere in the last 3 to 4 months when it comes up on my home page, which is Bing, if the picture of the day is a short video loop, which occurs 3 to 5 times a month, the video will not play. I have activated the control that says if a picture is a video, play it but this makes no difference. I have checked this out by running Internet Explorer, which also has Bing as my home page, and the short video loops run. I have also noticed that if the picture of the day is a video loop, the picture on Firefox is a different view of the same photo that is on Internet Explorer besides also not animating. Why is this? The latest video loop on Bing was yesterday (February 11). It did not animate on Bing and is a different view of the scene.
