Under MacOSX several internet settings which were available under MacOS 8 and 9 are still present and are still used by most internet applications, but they are no longer accessible by the user. So if these settings get corrupt for some reason there's no way to repair these settings anymore. MisFox makes some of the most important internet settings accessible again.
MisFox will show all the file mappings settings and the protocol helpers. You can inspect these settings, but you can also edit, delete and create new items for these settings.
