Most on-line videos use Adobe Flash Player which you do <u>'''NOT'''</u> have installed. If you had installed it, you would see "Shockwave Flash" under Tools > Add-ons > Plugins. Firefox and most other browsers use a Flash plug-in while IE uses an ActiveX version of Flash. <u>'''Install/Update Adobe Flash Player for Firefox'''</u>: your ver.
