On many web sites when trying to watch a video I get a message saying it is not available, but I can watch it if using Internet Explorer. How do I solve this issue?

I was able to watch videos such as CBS/60 minutes shows. Now, when I click on the video, I get a message stating that the video is unavailable. However, if I use Internet Explorer I can watch the video. Actually I can watch any video in any web site that I cannot longer watch using Firefox. Since I don't trust Internet Explorer, I wish you could find a solution to this issue, so I can continue using Firefox. Thank you

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

  • Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

"Remove Cookies" from sites causing problems:

  • Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Use Troubleshoot Mode in Firefox to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

I appreciate very much your input. I have now learned to clear the cache and remove cookies. I have also restarted Firefox in Safe mode. Unfortunately, the problem still there. Another example: I went to New York Times home page and I clicked on the 2 videos shown on the page of today's news. I get a similar message "The video you are trying to watch is currently unavailable". (I even subscribed to NYT online, but I have the same result). Then, I used the Internet Explorer browser and I can watch them both!!! very extrange thank you for looking into this...
