[R] start.help() and browser

[Christian Hoffmann]

Hi, when calling  help.start() I get the message

  "> sh: firefox: command not found"

and the help system is inaccessible (which is an absolute nuisance, but 
bypassable under  http://stat.ethz.ch/R-manual/R-patched/library/)

I have no idea what is broken in my system and I didn'n find any pointer 
in the archives(my search skills may be deficient..)

My sessionInfo():

Warning message:

I would appreciate help very much
