here's a good advice: forget it
simply, it's a HUGE security risk if you browse web as root. if you do it as a normal user and somebody or something cracks in, you may be safe from the very worst, but if you do it as root and somebody gets in, you're in a deep s**t. literally speaking, of course. anyway, it's a common suggestion that no-one should do nothing as root unless it's truly needed - normal users are for that, whatever it is. specially if it concerns using a network such as internet...even tough you'd be a home user with no important things on your machine, it's unwise to browse web as root. therefore, I'd say it's good you can't do it
sorry for saying you must not do it, but it just is so. why would you want to do it, anyway?
