I am still getting pop up windows every time I go to a new web page

What popups?

Else look under Settings and search for Popups to see the options

Thank you, but I already have pop up windows blocked and they are still happening.

Hi,

Could you please attach a screenshot of what you see?

Here is the URL of one of the pop up windows

I'd basically point you towards Troubleshoot Firefox issues caused by malware right away — if what you're saying is you go to e.g. wikipedia and click links there and you're getting random scam pages popping up that's definitely malware level at this point.

Thank you. I will do that even though I have Malwarebytes installed on my computer. I thought it was supposed to catch this kind of thing. When I run a scan it shows no problems.
