I'm getting Bad Request returned now from all websites. Anybody know what I may have done wrong? After selecting "Set Preference" do you just close the about:config window? (That's what I did. I'm a newbie.) I've restarted the browser and restarted my N800 and it doesn't help. I went back to the original settings (leaving Value blank) and that worked. And tried again to make the changes to make my N800 appear as an iTouch, and again all I get is Bad Request.
