Until bug 758383 is fixed I'd like to be able to move my experiment forward. Could you create a temp mozillalabs domain for my vcap domain. You don't have to use my name suggestion (search.mozillalabs.com) you could even give me search-vcap.mozillalabs.com if that's easier. The name isn't really that important to me just that the SSL cert is valid. Currently you can't do any kind of communication between your add-on and the vcap sites because the user must approve the security exception first. Thanks!
It's going to be search-vcap.mozillalabs.com. Once DNS makes its way around, you'll have to map your app to this new url by doing something like $> vmc map search search-vcap.mozillalabs.com
