Creating XMLHttpRequest in sandbox throws error

Are you on Nightly by chance?

Nightly bug: https://bugzilla.mozilla.org/show_bug.cgi?id=741367

Good catch! I keep forgetting that I should expect such issues in Nightly (it works so well most of the time ^^). Guess I should install Aurora for testing as well.

I had stumbled upon this problem in other extensions and already had a TODO to find an existing bug or otherwise track down the culprit and file one myself. Actually quite a few extensions are affected :p
Closing this issue now as I expect this will be fixed in m-c directly. In the unlikely case the bug makes it into m-a, then we may re-evaluate that decision.

Just a quick note: It works perfectly in Aurora, and after fixing the plugin a bit more, that works perfect as well ;)
