Addon is not opening

Hi. I’ve uploaded an addon few days ago and after mozilla approval I see that Addon is not opening (see picture below), but doing web-ext run in local it works fine. Whats wrong with the uploaded code?
Extension called: " Be12 Passvault Web Extension (Beta)".


Thank you!!

Have you checked the console for the popup page? Is the popup even loaded? See for help on where to find relevant debugging info.

Yes, I’ve checked console but the only thing I get is error occurred while processing 'sources: TypeError: can't access dead object.
