Linux – How to start Firefox maximized or fullscreen without any additional extensions

Install the AutoHide add-on, this will allow you to use the "-fullscreen" parameter on the command-line.

command line options can be found http://kb.mozillazine.org/Command_line_arguments and developer.mozilla.org/En/Command_Line_Options

but apparently the -console argument is windows only. Not sure if the lack of debug output launching it from a console on linux is because debug output is disabled for production compilations or some other strange reason.
