Malicious pop ups claiming to be from Mozilla firefox

Firefox Browser security

I keep getting annoying popups claiming to be from Mozilla Firefox. clicking on one takes me to a malicious website. Dismissing them only results in new ones opening. I am attaching a sample of a screen showing the popups on the right. I scanned for viruses and was told my computer is clean.

How can I stop this from happening?
