Are there Firefox extensions only hosted by Fedora that aren't available in AMO? Why can't these be made available through AMO instead? Off hand it doesn't really make sense to me that a whole separate extension signing infrastructure needs to be created.
No, but that's not really the point. One of the advantages to having extensions in Fedora proper is that it becomes much easier to produce a standard build for a company or home that has certain extensions available to all users, without all users needing to voluntarily download them from somewhere into their own Firefox profile. This can be for convenience or sometimes for compliance with a company's policies.

If you do the effort of providing a custom build you can also create a custom build of Firefox with certain signed extensions, like the Tor Browser does.
