how to block a Bing Popup?

Sometimes when I fall asleep in my easy chair I will get this random popup from Bing. I do not use Edge or Bing as internet browser or search engine. I have switched from Google Chrome to Firefox because of youtube policies. This is the popup:

" how to get help in windows 11 - å¿åº:

Then the rest of the page will show various Microsoft Help links

What is the popup? The web page randomly opens?
Odd. Id be more concerned if it popped up to “How do I get out of my easy chair”

Have you been into Firefox and removed Bing from the search settings?
What’s the home page for Firefox?

What add-ons do you have, if any?

I have a HP laptop similar to yours. I recall using Firefox, but I switched to using Chrome a very long time ago. However, I have never had the popup you describe. In chrome, I use two popup blockers (AdBlock and AdBlock+) plus a extension called Chrometana. Chrometana redirects Bing searches to something else. I don't deal with YouTube very often, so I don't know what the politics issue is.
When I do use YouTube, I have haven't had any issues.
