To enable or disable pop-up notifications in Firefox, follow these steps:

1. Open Firefox and click on the menu button (three horizontal lines) at the top right corner of the browser window.
2. From the dropdown menu, select "Options" (on Windows) or "Preferences" (on macOS).
3. In the options or preferences window, click on "Privacy & Security" from the left sidebar.
4. Scroll down to the "Permissions" section and locate the "Notifications" option.
5. To enable pop-up notifications, ensure that the "Block new requests asking to allow notifications" checkbox is unchecked.
6. To disable pop-up notifications, check the "Block new requests asking to allow notifications" checkbox.
7. You can also manage individual website notifications by clicking on the "Settings" button beside the checkbox. This allows you to block or allow notifications for specific websites.

Note: The steps may slightly vary depending on the version of Firefox you are using.
