Support browser.storage.sync.*

I know Tor browser didn't support Firefox Sync. It's okay but would you consider supporting browser.storage.sync.*?

browser.storage.local.* are working fine. browser.storage.sync.* will return nothing.

This is not my code's problem because sync. is working in Mozilla Firefox. How about treating storage.sync request as storage.local internally? (I'm not asking for enabling sync - I just want .sync to work as .local)
