Error message: InvalidStateError

Hello Slams,

Thanks for reporting that. That is very strange and we had another user report this error happening often as well. I suspect this error happens as a result of not being able to access the web storage database we use to store OneSignal-related data. In Firefox, this error occurs when visiting a OneSignal-enabled site while using Private Browsing mode. In our daily testing, we do not commonly run into this error; it only occurs in extreme edge cases or incompatible browser configs like private browsing mode. Please continue to update us if you notice any more of this!
