If I were to go and try and view the pro0ducts on http://www.mp4nation.net/catalog
I get redirected to a blank page with what you see in image on top left corner.
I realized it may be due to site not recognizing the browser properly simply due to the name on end due to me using Namoroka (1.9.2 branch nightlies behind Firefox 3.6.*) versus recognizing it as a Gecko browser http://geckoisgecko.org/
. I changed the user agent with the general.useragent.extra.firefox
preference to have Firefox instead and the site worked fine after a reload.
