Firefox 81: How to disable default browser Notification bar on New Tab Page

Back in April, Mozilla decided to know which web browser Firefox users use as their default on Windows and included a scheduled task called Firefox Browser Agent in Firefox to know about the same. Now, the company is testing a notification in Nightly where it will appear when you open the first new tab in a session and asks you to set Firefox as your default browser.

While the test is targeted for Firefox 81, right now, you can see the prompt in Firefox 82 Nightly.

To get started,

  1. Launch Nightly
  2. Open a new tab,
  3. You’ll receive a notification with a message asking to “Set Firefox as your default browser? Get fast, safe, and Private browsing whenever you use the web.”
    Set Nightly as your default browser notification Firefox new tab
    Set Nightly as your default browser notification on Firefox new tab
  4. If you don’t take any action, it will appear once in the next four sessions whenever you open a new tab.

Disabling Firefox’s default browser notification bar on New Tab Page

  1. Clicking on ‘x’ icon will close and disable the notification bar forever
  2. Or you can visit about:config and change the following pref value to false
    browser.defaultbrowser.notificationbar

If you click on “Set as default”, the Settings App opens on Windows 10 and allows you to choose and set Firefox as the default web browser

The notification bar appears only to users who don’t use Firefox as the default browser.

    I only use FF for certain tasks like banking which aren’t supported on my default browser which is Waterfox Classic.

    I have version 80 installed at the moment, but even when accessing about:config browser.defaultbrowser.notificationbar is already set to false.

    In Windows 8.1 Task Scheduler there’s no sign of the Firefox Browser Agent anywhere. Presumably that’s because I’ve elected not to send telemetry to Mozilla.
