Sadly, since a few days, AdBlocker Ultimate is blocking to many websites and they are not readable. I not even could read my Emails or login to important accounts!

Was very good and useful up until today 4/25/23; seems filters were updated the day prior and have since broken most sites, especially online stores

Worked very well until today. But for some reason it started breaking a lot of sites and make them unusable like for example PayPal.com. Had to deactive ADBlocker Ultimate to fix that. Hope its only temporaly and it will be fixed. until then its unusable.

Starting from today it breaks API requests on many websites making them to "freeze"

Brilliant ad blocker.... I don't see all the dross I used to see.... recommend for everyone.

More and more sites become unusable with this add-on

Was great until today - now breaks almost every site

Top Ad Blocker, very effective and easy to apply to web sites. Recommend.

Easy To Use, Works On All Websites, Not Slowing Down Firefox. In Essence, Awesome! i Recommend It!

it is exelent
