How to Remove 'Ads by deichmann.com' Pop-ups in Firefox on Windows 10?

In my browser, I see pop-ups signed as "Ads by deichmann.com", or other pop-ups with advertisements.

I attach a scan of the frst

How can I remove it?

Download the latest version of FRST from this page https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/ scan again and include the Addition.txt log.

I downloaded the new version from the indicated address and I attach both files again

Open the system notebook and paste:
