I suppose it works just fine. Previously I saw Facebook ad based on my searches even when I was not using FB. I didn't see any annoying ads of such kind on Firefox Quantum.

It works!

Excellent performance!

Great extension, would like to see a similar addon but for Google.

Smart plugin that works well

Probably the add-on I have been looking for ages! Good job and keep it up!
