the problem is the line(s) later in the script, ie

  case $BROWSER in
    firefox*)
      $BROWSER -a firefox -remote openurl\("file://$URL",new-window\) || \
        $BROWSER "file://$URL"

when i enter that command filled out :
  
  firefox -a firefox -remote openurl\("file//<helppath>",new-window\)

i get the error described above.  if i enter :

  firefox "file:///usr/local/share/xfce4/doc/C/index.html"

i get the msg "No running windows found", but Firefox does open the dox.

why does the script call up this long command ?

 2  things seem needed to make the script failsafe:
(1) to add 'lynx' to the list of browsers (usually installed, reliable);
(2) to make any error in opening a browser cause the script
to go back & try the next one on the list; alternatively,
if  BROWSER  is not defined, it cd ask the user to name his/her preference.
