Firefox 53 not working

[jgordor]

Since the release of firefox 53 the openUriUsingFirefox function, iframe.contentWindow.location.href = uri; don't throw any exception anymore.

failCb() is not called and successCb() transport the user to the Windows Store to open an unknown protocol (on windows 10) or nothing on windows <10 & mac.

Do you have any workaround about re-adding firefox support?

Sorry, seems that was something with the cache on the user profile, uninstalling the app keeps firefox thinking that can handle the protocol, not throwing NS_ERROR_UNKNOWN_PROTOCOL
