As of 2 days ago, can no longer open videos but instead get message "this video no longer available". However, if I use Internet Explorer I am able to open the video. Perhaps something changed in my security settings?

I have installed Firefox 6.0.

Reload web page(s) and bypass the cache.

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


You can also try to update the WMP plugin if that player is used.
