Firefox: Service Worker: SecurityError: DOMException: The Operation is insecure

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.

Solution

  • 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.
