And, since uBlock Origin doesn’t allow the “good” ads that most websites rely on for financial support, it can actually hinder the ability of your favorite sites to produce the content you love. For example, some web page elements may not display correctly. Of course, blocking everything results in other problems. Also, the fact that uBlock is open-source (meaning anyone can view and contribute to its source code) means it has access to many more block lists, and these lists can be added or removed as needed.

On the web, there’s no escaping annoying ads.īut online ads aren’t just an annoyance-they also put your privacy at risk.
