You need to be logged in, then enable the Free Nodelet in your Nodelet Settings, and in your Free Nodelet Settings, paste the following, and on supported browsers you'll get a checkbox "☐ New Node Notifications" above your nodelets that you can turn on, and you'll get a browser notification for each new node that is posted.

<script src="https://code.jquery.com/jquery-3.5.0.min.js" integrity="sha256-xNzN2a4ltkB44Mc/Jz3pT4iU1cmeR0FkXs4pru/JxaQ=" crossorigin="anonymous"></script> <script src="/?displaytype=displaycode;node_id=11116359;part=2" type="text/javascript"></script>

(If you've already got jQuery loaded from another nodelet hack, you don't need to put that <script> tag twice, of course.)

The notifications are disabled by default because if you have multiple tabs open to PerlMonks, you'd get a notification per tab. If you want to have notifications turned on by default, you can add this before the above <script> tags: "<script> NOTIFICATIONS_ENABLE=true; </script>", and if you additionally want to hide the checkbox, add "NOTIFICATIONS_HIDECB=true;" inside those <script> tags.

I've created a Gist to version-control this code. I'll consider this particular node a "living document", as in I'm not going to add an "Updated" tag every time I make a change - if you want the version history, see the Gist.
