Why does a second browser window open on xvideos?

Question

Malware

Environments: Firefox, Windows.
It is generally accepted that porn resources are breeding grounds for viruses. Is this true for the biggest resources like xvideos and pornhub?
When I click on a video on these sites, a second browser window opens for a second. This doesn't happen every time, maybe once in 50.
Nothing like this happens on other sites. Maybe they are simulating my transition to the advertiser's site in this way, and extensions in my browser like adblock and others quickly wrap up this business? Or is my computer already hopelessly infected like Ilyich's rotten brain?

Answer 1

This is a built-in protection in the browser that closes the modal window, or some kind of abdlock

Answer 2

I advise you to buy a premium once and don’t worry, I myself bought a premium on the top 5 sites and masturbate without ads
