Sounds like you logged in as a regular user, opened up a terminal program
like xterm, Eterm, Konsole, etc., and su'd (with the 'su' command or
similair) to root and tryed to start mozilla as root. This does not work
in Unix en thus Linux. In Unix de user that 'owns' the 'X' process that is
running is the Only user that can modify the X-screen, not even root can
This is a (security) feature not a bug. :)
