Could you check whether YouTube is serving its HTML5-based player or its Flash-based player? If you right-click the player, a short context menu should appear. If Firefox's full context menu appears, press and release the Alt key to clear that. The last line of the short menu usually indicates which player it is.

I'm going to assume HTML5 because...

On Windows 7, Firefox should show a broad range of formats in the HTML5 player. However, if certain media features are disabled, preventing decoding of MP4 video, then YouTube only offers 360p (with WebM encoding).

If you intentionally disabled Media Foundation and/or DirectShow in about:config, then perhaps you would prefer to use the Flash player on YouTube? There are a couple add-ons which can force YouTube to serve you a Flash player. Either of them will do, you don't need both:

Dear Sir,

Thank you for your help. I have installed https://addons.mozilla.org/firefox/addon/youtube-flash-player/ and I am able to change the picture quality on you tube now from 140, 240, 360 etc. Thank you for your help.

Thanks & Regards Raju Kumar
