While Firefox is open, websites which have been granted permission can send notifications to your browser, which displays them on the screen. {for fx72}Notifications only display when you press a key on your keyboard or tap/click anywhere on the website that you are accessing. If you have not interacted with the website, then the '''Notification''' permission [[Image:Notifications icon]] icon will only display in the address bar; the actual notification will not display.{/for} You can easily allow or disable notifications and control how they appear. {for not fx70}[[Image:Fx56AllowNotifications]]{/for}{for fx70}[[Image:Fx70AllowNotifications]]{/for} __TOC__ = Upgraded Notifications = Firefox can deliver on-screen notifications even when that site is not loaded. Using the Push API, a [https://www.w3.org/TR/push-api/ W3C standard], Firefox receives a push message and can show notifications (if permitted by the user) at any time. Sites can also use Push to update data in the background even without showing you a notification. If you already gave permission to a site to send notifications, the site will also be able to use the Push API. You can choose whether or not to give permission for a specific website by following these instructions: {for not fx70} # Click the '''Site Information''' [[Image:Site Info button]] icon in the address bar to bring up the [[Control Center - manage site privacy and security controls|Control Center]] panel. # Click the arrow in the panel. # Click {button More information} in the next panel to bring up the [[Firefox Page Info window|Page Info window]]. # Click the '''Permissions''' tab. # Under {for not fx64}'''Receive Notifications'''{/for}{for fx64}'''Send Notifications'''{/for}, choose a notification option: {menu Always Ask}, {menu Allow}, or {menu Block}.

If your choices are grayed out, deselect the '''Use Default''' checkbox. {/for} Alternatively, you can: # [[Template:optionspreferences]] # Click '''Privacy & Security''' from the left pane. # Scroll to the '''Permissions''' section. # Click the {button Settings...} button to the right of '''Notifications'''. # Select '''Allow''' or '''Block''' from the '''Status''' drop-down for any of the websites. # Click the {button Save Changes} button. = What is Web Push? = Web Push is an optional feature that allows websites to send you messages even when the site is not loaded. Sites can use this feature to provide you with notifications or update data in the background. For example, you can subscribe to notifications from your favorite shopping websites that can notify you of new promotions or offers. You can subscribe to notifications from different websites. A concert site may offer you notifications for shows of your favorite band. You decide to allow that site to notify you, and a week later you get a notification that your band is on tour. You will only receive messages from sites that you have granted permission. = How does it work? = Websites can install a [https://developer.mozilla.org/docs/Web/API/Service_Worker_API Service Worker], a background web page with a limited set of functionality, that can subscribe to the push service. The website can then send a push message through Mozilla’s Web Push service to your browser, which can process that message and display a notification on your screen. ;[[Image:push notification 44]] Clicking the notification can open a website or switch to that site’s tab if loaded. = What information do I share with a website? = A website that has been granted permissions can send you push messages when the site is not loaded. A quota limits the number of push messages without an on-screen notification that websites can send you. Websites that exceed the quota will have its push messaging disabled and the user must revisit the website again to resubscribe. Web Push does not directly allow websites to determine your IP address. = What information does Firefox use to provide Web Push? = Firefox maintains an active connection to a push service in order to receive push messages as long as it is open. The connection ends when Firefox is closed. We store a randomized identifier (User Agent IDentifier or UAID) on our server for your browser, along with a random client-generated identifier for each push subscription. When you have any subscriptions, the UAID is required to allow our push service to route incoming messages to Firefox. If you don't have any active push notification subscriptions, Firefox rotates the UAID on each new connection. On Firefox for desktop, the push service is operated by Mozilla. Firefox for Android uses a combination of the Mozilla Web Push service and Google’s Cloud Messaging platform to deliver notifications to Firefox for Android. Push currently is only used by Mozilla on iOS platforms. In both cases, push messages are encrypted per the [https://tools.ietf.org/html/rfc8030 IETF spec], and only your copy of Firefox can decipher them. The encrypted messages are stored on the server until they are delivered or expire. We store your IP address for 90 days as part of this service. It is invalidated when either the IP Address or UAID is changed. We do not store information about: *the servers and/or services that have sent messages *when a particular user agent was online/active = How do I revoke Web Push permissions for a specific site? = Web Push is always opt-in in Firefox. A site cannot send you push messages without your permission. To stop a specific site from sending you push messages: # [[Template:optionspreferences]] # Click '''Privacy & Security''' from the left pane. # Scroll to the '''Permissions''' section. # Click the {button Settings…} button next to '''Notifications'''. # Select the website. # Click the {button Remove Website} button. To stop all sites from sending you push messages, follow the steps above but instead of selecting a specific site click the {button Remove All Websites} button. Websites will not be able to send you messages and will need to ask your permission to send them in the future. {note}'''To stop notifications on a specific webpage (requires a page reload):''' Click the {for not fx70}'''Site Information''' [[Image:Site Info button]] icon to bring up the [[Control Center - manage site privacy and security controls|Control Center]]{/for}{for fx70}padlock [[Image:Gray padlock - Firefox 70]] to bring up the '''Site Information''' panel{/for} for the website, find the {for not fx64}''Receive Notifications''{/for}{for fx64}''Send Notifications''{/for} permission and click the '''x''' next to ''Allowed'' to remove the permission. {/note} = How do I add Web Push to my website? = The [https://developer.mozilla.org/docs/Web/API/Push_API Push API specification] explains how to create a Service Worker and send push messages. = How do I stop Firefox asking me to allow notifications? = If a site indicates to Firefox that it wants to show notifications, by default, Firefox asks whether you want to grant permission. You can set Firefox to automatically deny permission without asking. Even after the change, you can make exceptions for sites ''you want'' to show notifications or use push features. # [[Template:optionspreferences]] # Click '''Privacy & Security''' from the left pane. # Scroll to the '''Permissions''' section. # Click the {button Settings…} button to the right of '''Notifications'''. #;[[Image:Fx59Permissions-NotificationSettings]] # Select the '''Block new requests asking to allow notifications''' checkbox. # Click the {button Save Changes} button.
