What is Adblock Plus?
Adblock Plus is a free extension that allows you to customize your web experience. You can block annoying ads, disable tracking and lots more. It’s available for all major desktop browsers and for your mobile devices.

Adblock Plus is an open source project licensed under GPLv3 and subject to its Terms of Use.

How does Adblock Plus work?
Choose what you want to see when browsing the web by using filter lists to block unwanted elements, like ads or tracking.

What are filter lists?
Filter lists are sets of rules that tell your browser which elements to block. You can block as little or as much as you want. Choose from pre-made, externally maintained filter lists, or create your own (English only). Almost all pre-made filter lists are created, published and maintained by users for users under open source licenses.

Many ads have tracking built in and some may even contain malware. Because of this, Adblock Plus provides certain levels of tracking and malware protection by default. If you want, you can add additional tracking and malware filter lists to increase your protection.

Default filter lists:
The following filter lists are enabled by default when you install Adblock Plus:

Blacklisted Ads:
A filter list that blocks ads (e.g. EasyList) based on your browser’s language settings.

eyeo GmbH is not related to the EasyList project and therefore has no right to, or control over, its filter list content. Visit the EasyList Community for more information.

Acceptable Ads:
A feature that supports a better web by allowing nonintrusive, respectful ads that comply with the Acceptable Ads criteria agreed upon by the Acceptable Ads Committee.

This list is open source. Want to block all ads? No problem. Click here to learn how.

These filter lists are enabled to get you started. You can keep them, modify them, remove them and / or add other filter lists - it’s up to you.


Does Adblock Plus collect any user data?
We do not specifically collect any user data. Most of your data (e.g. what websites you visit) is never sent to our servers to begin with. Please see our Privacy Policy for more details.

How is Adblock Plus financed?
Our main source of revenue comes as part of the Acceptable Ads initiative, which is managed by an independent committee.

Implementing the Acceptable Ads criteria is part of eyeo’s (the company behind Adblock Plus) attempt to pursue a different vision of online advertising. It requires significant effort on eyeo’s side including, but not limited to, ongoing review and monitoring of the individual whitelisted ads, advising participants, and providing technical support. These services cannot be done as a hobby, or completely taken over by volunteers.

Therefore we only charge large entities a license fee so that we can offer the same whitelisting services to everyone and maintain our resources to develop the best software for our users.
