If your distribution is built with GCC 3.3 this version may not work for you.
To view an external URL (to browse an edited file or select one Help menu entry) with Mozilla Application Suite, install this executable script in your system, for instance in the directory where mozilla lives. Edit the MOZILLA_FIVE_HOME environment variable in that script to meet your system settings. Add the following lines to your prefs.js:

user_pref("network.protocol-handler.app.http", "/path/to/the_shell_script"); user_pref("network.protocol-handler.app.https", "/path/to/the_shell_script"); user_pref("network.protocol-handler.app.ftp", "/path/to/the_shell_script"); user_pref("network.protocol-handler.app.file", "/path/to/the_shell_script");

For Mozilla Firebird, adjust that variable too and change the last line of the script to

exec $MOZILLA_FIVE_HOME/MozillaFirebird $url
