This use to work great at blocking ads on YouTube, but not now. It makes it so it says I have no internet, until I shut it off. When I turn it back on, it lets at least one ad thru. It also is blocking necessary links from working on sites like SSA, TurboTax, etc. I'm disappointed.

I have yet after years of use using Firefox ad blocker seen ad's popping up. Highly recommended. David
