Firefox isn't, by any means, only 6K.  The script in /usr/bin is 6K, but 
it ends up firing up, eventually, firefox-bin, which is 127K and links 
into 42 different shared libraries on my centos5 box.  Some of those 
shared libs are firefox specific, as well, so they won't be in memory 
before firefox is run.

That just means even more files and more data to read into memory before 
firefox can start up properly.
