I am using Mozilla firefox since IE is really slow and my google chrome has too many glitches as well. Everything works great on Mozilla except that I get quite a few emails from a site called Mens Health. IN a lot of the emails - there are videos and MOST of the videos that need to be opened when I click on an exercise within the email sent to me does NOT open. I am not sure what I need to install as per plug ins or add on's to enable me to have these videos open. In the body of the email- it shows the explanation of the video with a huge blank space where the video should be and it never opens -- it just remains a huge blank space(white). Any ideas???
