Firefox Push Notifications: A Beginner’s Guides

Firefox (version 44+) for Windows, Mac, and Linux now lets you choose if you want to receive browser push notifications from websites if you’ve given them permission. This is similar to Web notifications, except now you can receive notifications for websites even when they’re not loaded in a tab.

This is super useful for websites like shopping (eCommerce), online retail business, news, email, weather and social networks which you might check frequently for updates.

This new marketing channel helps re-engage your site visitors without requiring them to submit their email or other contact details.

All that the user must do is subscribe to notifications from your brand when prompted. Web Push Notifications  already work on over 85% of devices.

Notifications from websites are indistinguishable from native notifications, and Vizury’s demo e-commerce site showcases a live demo where you can see this for yourself.

Much like with geolocation or webcam access, Web Push requires explicit, revocable permission before a website can show notifications to a user.

Why should you use Firefox Push Notifications?

This is what David Bryant, Vice President of Platform Engineering and Interim CTO at Mozilla has to say about desktop push notifications.

As part of Mozilla’s mission to promote openness, innovation and opportunity on the Web we not only make our own products, like Firefox, but work on technologies that will benefit the entire Web ecosystem. We do this because we want the Web to reach its full potential and grow with interoperable and consistent experiences for both users and developers. This includes experimenting with Service Workers and other technologies that enable a new design pattern known as Progressive Web Apps -a key next step in the Web Apps story”

Push notifications are one of the most valuable capabilities of native apps, and this experience is now available on the web. To get the most out of Web Push Notifications, it needs to be timely, precise, and relevant at a user level.

3 step process to start web push notifications

How does Firefox Push work?

Here is a simple 5 steps process to understand and send firefox push notifications:

1. Requesting permission

You start with asking your visitors for permission to send web notifications.

2. Registering a service worker and subscribing to push

Then you register a service worker (It is a small JavaScript program with superpowers like intercepting network requests or running even when their parent website is closed) to control the website. You basically identify your visitors here and get their device token id.

Here, you can get your visitors to subscribe for web push notifications.

It returns a Promise that resolves with a Push Subscription object. The subscription object exposes metadata about the subscription, including a unique endpoint URL on your browser vendor’s Push Service.

3. Push servers, and sending push messages

You need a server component to send push notifications. These servers should be able to handle secure request/ response and data encryption.

Whenever the website POSTs to that endpoint, the Push Service routes the message to your browser, where the appropriate Service Worker receives a push event. The Service Worker can then show a notification or take other actions.

4. The service worker, and responding to push messages

The website uses the push manager to either get an existing subscription or create a new one. So, you will also need to set up a responder to respond to push messages being received.

5. Handling premature subscription expiration

Sometimes push subscriptions to expire prematurely, without unsubscribing being called. This can happen when the server gets overloaded, or if you are offline for a long time. This is highly server-dependent, so the exact behavior is difficult to predict.

What about privacy?

Web Push works by maintaining a persistent connection to a Push Service that acts as a central relay for messages. Each browser vendor runs its own Push Service, and it’s been designed to safeguard your privacy:

1. To prevent cross-site correlations, every website receives a different, anonymous Web Push identifier for your browser.

2. To thwart eavesdropping, payloads are encrypted to a public/private keypair held only by your browser.

3. Firefox only connects to the Push Service if you have an active Web Push subscription. This could be to a website, or to a browser feature like Firefox Hello or Firefox Sync.

You’re always in control: Push notifications are opt-in, and you can revoke permission from any website at any time, either from the page info panel or from the “Notifications” section in Preferences → Content.


Web push notifications are one of the best communication channels in the entire spectrum. Chrome, Safari, and Firefox cover almost 75% of the total browser stack. Firefox push browser notifications are unique in terms of technology and deliverability.

They are prompt, relevant and very specific. With little advancement in the technology they can be personalized. For example, you can insert individual-specific information to make good use of it.

Firefox push notifications, in short, are the game-changing medium of communication.
