I can watch videos in IE. I don't like IE. I cant watch videos from any website using firefox. All my firefox plugins are up to date. It's just not adding up.
Sorry Firefox on Windows has been having issues with use of Flash Player 11.3
Instead of using the latest version it may at the moment be best to uninstal Flash 1l.3 and downgrade to Flas 10.3 or 11.2.
See the latest revision of Adobe Flash plugin has crashed - Prevent it from happening again and any articles linked from there.
Developersfrom Flash and Firefox have been working for a few days to find reliable fixes for these issues. (As a separate issue RealPlayer use may also cause problems)
