Love it. Updating my review. Since FF57 it works well!

Super gut

Cette extension est bien efficace car je m'en suis déjà servi auparavant. Merci.

Makes a huge difference.

Works great (using FF 57) and is easy to use. Miles better than bloated adblocker plus. Highest recommendation.

Keep things private

Nice

The Best!

Very effective at blocking unwanted ads and a few times has prevented me from accidentally visiting dangerous sites. 99% of the time it has no impact, and very easy to disable on a per site basis if necessary

Leve, eficiente, open-source, desenvolvimento constante, e muito mais, o melhor bloqueador de anúncios!

Best of the best, and actively maintained for years! Even includes an element selector, so useful!

Sometimes cryptic but still the best adblocker in town.

And I finally managed to get rid of the "Ebay Problem":

I additionally installed "umatrix" and allowed everything but "googletagservices.com", "ioam.de" and "247-inc.net" (these may vary in different countries, I'm at Ebay Germany). Now everything's fine!
