We've gone ahead and started to remove the preferences that would
control what apps would be launched for external protocol and content
handling on unix. The reasoning behind this is that we are providing
a UI that lets the user accomplish this now, and the preferences
created additional code paths that complicate the code (which is
already overly complicated).
If you have any questions, concerns, or comments, please let us know.

A bug number would be most useful as a start.
It happened in Bug 385065.
