Popups are occurring INSIDE of the Firefox window

Question

Are these pop-ins or slide-ins the fault of the web page? The site?

Answer 1

You can look at the Adblock Plus extension if you want to block content.
* Adblock Plus: https://addons.mozilla.org/firefox/addon/adblock-plus/
You need to subscribe to a Filter list (e.g. the EasyList).

Do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.
