Which "mozilla" accepts options

[Ben Washington-Yule]

Hi all,

"mozilla -help" gives loads of options, the ones I'm interested in are 
-height <value> and -width <value>, but I have on my computer 
/usr/X11R6/bin/mozilla (a shell script), /usr/X11R6/lib/mozilla/mozilla 
(also a shell script) and /usr/X11R6/lib/mozilla/mozilla-bin (an 
executable), which of the "mozilla"s do I pass options to? I have tried 
all of them with little success.
