I am using firefox, recently when a video has been posted I cannot view it. The box says a plugin needed to display this content. what plugin? Clicking it does not give me a download option.

I don't know if this will help but I use the HTML 5 vs the Adobe video player. You can select that in Firefox.
Do you have the Apple Quicktime plug in installed on your system. 7.7.6 I think is the latest. Look in your firefox/options/applications
