Websites can ask you to accept several different kinds of communications and updates:

• Desktop notifications - if allowed, the site can send notifications for Firefox to display in the lower corner of your screen until you close the last tab for a site.
• Web push notifications - if allowed, the site can send desktop notifications for Firefox to display in the lower corner of your screen even after the last tab for the site is closed (until you exit Firefox).
• Web push updates - if allowed, the site can send Firefox updates in the background, which presumably is more efficient that forcibly refreshing a page or having a script in the page keep checking for updates. This push feature is NOT a desktop notification, but Firefox may use the notification permission panel, which I hope will be changed in the future since that's a bit confusing.

Site-Specific Permissions/Blocks

If the drop-panel is not available or does not work for you, while viewing the site where you want to modify a previously given permission, you can use the Permissions panel of the Page Info dialog. To call that up, either:

• right-click (on Mac, Ctrl+click) a blank area of the page and choose View Page Info > Permissions

(menu bar) Tools menu > Page Info > Permissions click the padlock or "i" icon to the left of the site address, then the ">" icon, then More Information > Permissions

Scroll down to "Receive Notifications" and you can check the "Use default" box (so you are prompted in the future) or uncheck that box and select the permission you prefer (for example, Block).

There's no save button for this panel, changes are saved as you go.

Session Do Not Disturb

To disable all desktop notifications for the rest of your Firefox session (i.e., until you exit Firefox), you can turn on "Do Not Disturb" on the Options/Preferences page, Content panel. Either:

• Windows: "3-bar" menu button (or Tools menu) > Options, then in the left column click Content
• Mac: "3-bar" menu button (or Firefox menu) > Preferences, then in the left column click Content
• Linux: "3-bar" menu button (or Edit menu) > Preferences, then in the left column click Content
• Anyone: Type or paste about:preferences#content in the address bar and press Enter/Return (you can bookmark this for faster future access)

On the right side, under "Notifications", check the "Do not disturb me" box. This is for your current session only.

All-Site Persistent Disable

There are two different preferences for notifications, a master switch, and one which is specific to background (web push) notifications that can appear after you leave the site which sends them.

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste webno and pause while the list is filtered

(3) To disable PUSH NOTIFICATIONS, double-click the dom.webnotifications.serviceworker.enabled preference to switch its value from true to false -- sites can still generate desktop notifications while you have a tab open to the site

(4) To disable ALL NOTIFICATIONS, double-click the dom.webnotifications.enabled preference to switch its value from true to false -- this is a master switch, you won't get any desktop notifications from sites

(5) To also disable BACKGROUND UPDATES, double-click the dom.push.enabled preference to switch its value from true to false -- but that may block actually useful services from sites you trust, so I don't recommend it at this point. (Note: you need to edit the text in the filter box above the list to display this preference.)

Troubleshooting: Site-Specific Permissions Are Forgotten?

Whether you enter a site permission through a drop-panel or the Page Info dialog, Firefox should remember your choice. If you are losing site-specific permissions, one possible reason is if Firefox is set to "Clear history" when it closes on the Options/Preferences page.

If you use that setting, check to the right of it for a Settings button. Click that, and make sure that "Site Preferences" is not checked -- when that's checked, you'll lose all your Allow/Block settings every time you close Firefox.

Troubleshooting: Pages still display a permission dialog

Website scripts can display pre-permission dialogs even if Firefox ultimately won't allow the services. This is beyond the control of Firefox, but possibly could be tamped down with add-ons/extensions.

Hi,

Thank you for the very detailed reply. I have both .enabled and .serviceworker set to false. Can you elaborate on what you mean by pre-permission dialogs?

The requests I'm referring to aren't showing up as js alerts or anything- they appear to me to be the actual request to send notifications. Was I misunderstanding what the about:config settings do?

My ultimate goal is to never see any notifications- web, push, desktop, or other- for any website, or be asked if I would like to.

That Ultimate goal may have to wait until it is all figured out how to stop it.

If did what I suggested above in about:config and did as suggested when the Notifications come in then those will stop if you follow that. Take away their permissions as the come in.

There is no cure for everything yet. This one takes work on your part to do about:config and as they come in.

Check back in the future.
