I have ported a Chrome FireFox extension. One of the things that does not work is receiving message from background to a options page (safari-web-extension://<id>/page.html) I dont get a error message or any details back from the promise. Any idea where this goes wrong? Background: browser.tabs.sendMessage(tab.id, { message }); Options page: browser.runtime.onMessage.addListener(message => { console.log(message); });
