Notifications not working

Since updating to Firefox 70.0 my desktop notifications aren't working on Windows 7 PC. I used to get a notification near the Windows taskbar when I received an email or a facebook event. I've checked in Firefox options and they are definitely enabled. I've also checked on the permissions for the individual sites and notifications are definitely set to Allow. I've tried clearing the cache/cookies/data completely. I've also tried disabling notifications and then re-enabling them

teps to reproduce:

Ran a web app that posted a desktop notification.


Actual results:

The notification disappeared automatically after 2 seconds. This is the same behavior that the HTML Desktop Notifications add-on used to have; the add-on has now been fixed so that the notifications stay up.


Expected results:

The notification should remain visible until it is closed by the user or the web app. This particular web app (in development) depends on the notification remaining visible so that the user can refer to it while working in another window.

My problem is not that notifications are quickly disappearing - the problem is that they are not appearing at all !

My notifications are already set to 'Allow' for the relevant sites

Hello DavidM,

As you are talking about notifications on Windows taskbar; maybe,
for some reason, the notifications feature has been turned off in Windows' Settings - you could check to make sure :

Settings => System => Notifications & actions

Windows notifications are definitely enabled and working fine (taskbar popus eg. windows update are showing ok) but the desktop notifications i used to get from firefox are no longer appearing at all

Would you try this please :

Type in the address bar about:config and press Enter (promise to be careful, if asked)

Type in the search bar and look for the preference :

alerts.useSystemBackend

and set its value to true (default value is "false")

Then close and restart Firefox.



On the "about:config" page you could check this :

Type in the search bar notifications

And look for the preference :

dom.webnotifications.enabled

and make sure its value is set to true

Thanks, but I can confirm that both settings are set to 'True'. I've closed and restarted firefox but the problem persists

Running out of ideas .....

Maybe try to toggle some other "dom.webnotifications" preferences ?

You've already done everything in the book  :(

Hi. I know, I don't understand it either!! I've experimented by setting every one of the 'notification' options to true but it still hasn't worked. I've again cleared cache / cookies / data, restarted firefox, rebooted computer etc etc, but no good.

I don't know which email provider(s) you use, but as for Facebook; does this help (?) :

https://www.facebook.com/help/269880466696699/?helpref=hc_fnav

Probably not, as you've already tried just about everything ..... :(



I forgot to ask : do you get the desktop notifications when you use another browser ?

Is this about desktop notifications or about push notifications?

You can see all registered service workers on these pages: about:serviceworkers and about:debugging#workers You can check WebSockets via this page: about:networking#websockets See also serviceworker.txt in the profile folder.

There is a checkbox in Page Info for the current website:

  • Tools -> Page Info -> Permissions : Receive Notifications

You can check what websites you have allowed to send you messages via the Push API.

  • Options/Preferences -> Privacy & Security -> Permissions -> Notifications

Yeah, Facebook notification settings are all active. I haven't tried a different browser yet but I guess I'll need to. I usually only use Firefox though as I'm loyal to it.

The 'serviceworkers' shows that there are entries for facebook and outlook so that seems ok. there are 2 entries for outlook and on the debugging page, one of them is Running (https://outlook.live.com/mail/sw.js) and the other is Stopped (https://outlook.live.com/mail/sw_webpush.js). I've tried unregistering both of them, then restarting firefox, then opening outlook and clicking on 'allow notification' when prompted. it hasn't worked though!

1. Open Mozilla Firefox and type about:config in the addressbar and press Enter. It'll show you a warning message, click on "I accept the risk!" button.

2. Now type alerts in Search filter box and it'll show following preference in the window:

   alerts.useSystemBackend

3. If the preference value is set to true, it means Firefox will show websites notifications in Windows 10 Action Center. If the value is set to false, it means Firefox will show notifications in its own notification system.


To modify the preference, double-click on alerts.useSystemBackend preference and change its value. Alternatively, you can right-click on the preference and select Toggle option.

To enable Windows 10 Action Center support i.e. show notifications in Action Center, set the value to true.

To disable Windows 10 Action Center support i.e. show notifications in Firefox classic notification system, set the value to false.

Thanks but I've already tried that. I've tried setting it with both 'true' and 'false' but I'm still not getting the notifications. I'm on Windows 7

One of the most common reasons why iPhone notifications are not working is because Do Not Disturb is turned on. ... To turn off Do Not Disturb, open the Settings app on your iPhone and tap Do Not Disturb. Then, tap on the switch next to Do Not Disturb to turn it off.
