No specific configuration is required as long as the mozilla binary is in the path for the user. If Mozilla is installed in a non-standard location, then make a sym-link to the mozilla binary from /usr/bin. Same thing applies for Mozilla Firebird and Mozilla Thunderbird.

You may make the following symlink for convenience. ln -sf mozilla /usr/bin/netscape For installing various Mozilla plugins, refer to Mozdev's PluginDoc Project
