Lately, when I'm on a website and click into an article to read, suddenly the McAfee anti-virus ad or whatever you call intrudes and takes over the browser page I'm on and won't allow me to navigate way or stop it unless I close the browser tab and/or navigate away from the page all together.

Why is this happening? Is it something in the my particular browser? If yes, how can I remove and prevent this from happening?

Is it something that is occurring on the server of the site I'm visiting? Should I notify them what is happening?

Any help and advice greatly appreciated. It is very annoying. I don't have McAfee installed and it's not a pop-up, it happens within the browser page itself.

Thank you,

Marty

You can do a malware scan, just to be sure.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can install a content blocking extension like uBlock Origin.
