In app.js
,
I am checking the serviceWorker existence in navigator object and if available then registering the SW.
if ('serviceWorker' in navigator) { navigator.serviceWorker.register('./service-worker.js', { scope: './' }) .then(function(registration) { console.log("Service Worker Registered!"); }).catch(function(err) { console.log("Service Worker not registered!", err); }); }
When trying to register SW, I receive the below error in Firefox. I also made sure the service-worker.js
file is under src directory.
Checking my about:config in Firefox (version 59.0.2) I had service worker and storage api enabled. So that shouldn’t be an issue.
PS: The same code works fine on Chrome.

Did you check the cookie setting in about:preferences#privacy, it must be ‘keep until they expire’, if you have ‘keep until I close firefox’ selected sw will not register.
