In recent weeks, this add-on (after a thorough examination by the protocol dictated at support.mozilla.org) is causing all sites to be loaded slowly.
disabling this add-on, eliminates the problem instantly.

...

all these pop up ads slow down browsing speeds. This app fixed it!

removes just as many ads as Ad-Block plus and is also immune to many ad-block detectors that ask you to disable your ad-blocker for their site

Aos brasileiros que procuram um bom adblock: não procurem mais, pois encontraste!

I WAS USING AD BLOCKER PLUS AS WELL AS FOR YOU TUBE,I REMOVED THE PLUS SINCE I THOUGHT WAS ONLY THE ADS ON YOU TUBE I HATE,1 HR LATER I KNEW ADS ARE EVERYWHERE! THIS ULTIMATE IS ULTIMATE!

Very good AdBlocker.Do the job excellent.

1. Installed
2. Went to "spiegel-online.de", need to hide the "refresh homepage"-banner
3. Clicked at the "Element blockieren" in the Adblocker menu
4. Nothing happend
5. No help, no tutorial nowhere
but 3 buttons for Facebook, Twitter, Google in the menu. I HATE such buttons of such companies everywhere.

Moreover AdBlocker Ultimate is not configurable at all.

Last but not least: Who works behind this Add-on? It looks very dubious for me.

Wonderful add-on, just block any ad that can disturb or make your experience when visiting sites or watching YT not enjoyable.

At first glance is seems to be working fine but I have serious concerns about privacy for this Addon.
Obviously it is tracking what we are viewing. Everything comes at a cost, NOTHING is free.

This is the best no ads is like no other.....

Works very well, great addon))

Very good adblocker, but since the last firefox update to version 55.0, some pages are shown after loading for a short time as raw html without css formatting.

AdBlocker Ultimate is the best blocker forever.
