Firefox-Hilfeforum

When I hit cmd+l to select the URL bar, the first entry in the suggestion list is "Search with Amazon.com" with a pin icon to the left of it. I've searched all through the preferences and even about:config and any reference to Amazon is disabled. How can I get this to go away?

Hello dear Mozilla community!

I've faced an issue with search engines configuration for Firefox on macOS. I'm doing the following:

1. Removing all but one One-Click Search Engines, leaving only one engine in the list (currently my preference is DuckDuckGo): https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-41-395a2a.png or https://imgur.com/DKqvzZ9
2. When I type search request in the address bar I'm seeing nice and clean search suggestions from Search Provider of my choice: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-13-a8d46c.png or https://imgur.com/a/slivHlF
3. Close Firefox
4. (not sure what other conditions needed)
5. Open Firefox
6. When typing search request in the address bar I see that Amazon and Ebay options are back and a suggestion line "This time, search with ..." as added by firefox: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-02-4a25db.png or https://imgur.com/vjq0NCf
7. In the preference I see that those two searches (Ebay and Amazon) were automatically re-added to One-Click Search Engines: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-23-91dd1d.png or https://imgur.com/ibnlzLS

That issue is happening to me across different versions of firefox and isn't new. I've been seeing it for a few month hoping that to resolve in a newer versions. But as of right now I'm on 82.0.3 (64-bit) and the issue is still there.

It's a bit annoying as I have to my preferences literally every time I need to restart Firefox (which is especially annoying to do right after restarting FF to switch to a newer version).

Any suggestions and help is welcome!

Best regards, Serhii.
