Using Firefox 9.0.1 Some sites are being viewed as if I where using my mobile phone - for example, if I go to DirecTV.com, I see their Mobile site design.. this does not happen with IE or Chrome.

Also having sparatic issues with site style sheets not displaying correctly. Gmail.com is also not recognizing firefox as a valid browser

Tried all of the suggestions on those links and Firefox is still loading Yahoo.com and Weather.com as mobile version. In addition, Facebook claims I have an incompatible browser and will not let me view it at all.
