Where did you install it from? How did you install it?

Your .desktop file for the application seems to export a mime-type that says it handles HTTP (otherwise it wouldn't show up in the list) but then doesn't list any mime-types (which returns NULL, hence the crash).
Comment 13 bztdlinux 2015-02-18 21:39:15 UTC 
The Firefox Nightly build is Mozilla's official x86_64 binary, unzipped and run locally from my local directory. It prompts to set itself as the default browser, which seems not to work properly.

This might be a bug in Firefox too, but it shouldn't crash gnome-control-center.

    info: Fix crash when application supports no mime-type
    
    It seems to be possible for Firefox Nightly to set itself up as the
    default x-scheme-handler/http without actually handling any mime-types.
    
    See https://bugzilla.redhat.com/show_bug.cgi?id=1193680
    
    https://bugzilla.gnome.org/show_bug.cgi?id=744695

You'll want to file a bug against Firefox so it adds the MimeTypes= line when creating its own .desktop file though.
