Shells are a little more flexible about executing scripts than the
kernel is. If you have a script which doesn't start with a #! line, it
will typically run okay from a shell (which will run it through
/bin/sh), but if a program execs it directly, it won't work.
Presumably netscape execs the script through /bin/sh and thus doesn't
have a problem; mozilla, on the other hand, would seem to exec the
script directly.
Bottom line: always begin a script with a #! line.
