Reliance on unsafeWindow means changes are now needed for compatibility with GM 2.0 and later. From the page:

"For stability, reliability, and security the privileged sandbox has been updated to match the new changes to unsafeWindow for the Add-on SDK. In order to write values to unsafeWindow you will need to use the new methods cloneInto(), exportFunction(), and/or createObjectIn()."

The migration to the new API is nearly complete. I'll release the update as soon as it is ready.

Thanks for your patience.
