Allowing custom worker path for FF extensions?

[hleekeeper]

Is there any plan to allow the custom worker path for Firefox extensions? #217
Because of the Blob URL, we need to update the CSP settings for the extensions but we're hesitant to do that.

This made us drop the qr-scanner library and use other library for scanning QR code. Is there any plan for supporting the custom worker path in the future? We'd love to use the qr-scanner library if it doesn't require our extension CSP policy updates.
