I believe that the Addon SDK (a.k.a. JetPack) has special provisions for this; See [1], section "Content Scripts." In particular, I think that if you inject a "content script" into the <browser> then the "content script" will be able to make cross-origin requests like you propose. At least, I know that the Addon SDK required an extension to the nsIPrincipal interface to support multi-origin principals for this case. I am particularly interested if this strategy would work for you and other addon developers.
