After adding and activating, I tested YouTube video immediately. There was no Ads anymore. It works very well. Thank you, the publisher of ProBlocker!

How it works Ads are stopped before
Ads are stopped before
they enter the page. ProBlocker checks each request as it happens,
matches ad and tracker domains, and cancels
them before anything downloads.
Live request path 4-step network decision
1 Request begins
You navigate to a page
Your browser begins fetching the page and all its dependencies — including calls to ad networks.
2 Live inspection
ProBlocker intercepts each request
Before any request completes, ProBlocker checks it against filter rules covering known ad and tracker domains.
3 Rule match
Ad requests are cancelled
Requests matching filter rules are cancelled. The ad server never responds. No content downloads.
4 Clean render
Page loads without ads
The page renders with ads absent — not hidden, not covered, but never loaded. Pages load faster.
