Introduction to Filter Lists

Nearly all ad blockers, including AdBlock, use rules to determine what should be blocked and hidden on web pages you visit. These rules are also known as filters, and they are provided in collections called filter lists.


The filter lists are maintained by volunteers in their spare time. With a few exceptions, the list authors are not affiliated with the developers of ad blockers. For instance, we maintain the AdBlock Custom filter list, but all the other filter lists available in AdBlock are kept up-to-date by the authors of those particular filter lists. This is why we may have to refer you to the list authors for help when a filter breaks a web page or an ad slips through a filter list. Whenever possible, the list authors will fix the filter or adjust the blocking rules and release an update to the filter list, resolving the issue for everyone.


The most widely used filter lists are available as selectable options in AdBlock's settings. While some filter lists are found in all versions of AdBlock, not all lists are available in AdBlock on every device.

Ad Blocking Filter Lists

Acceptable Ads

The Acceptable Ads filter list blocks intrusive, annoying ads while allowing ads that abide by Acceptable Ads standards. The intention is to support websites that try to be good internet citizens. You're welcome to disable it at any time. This list is enabled by default when AdBlock is installed. The optional "Only allow ads without third-party tracking" feature can be enabled when Acceptable Ads is selected.


Acceptable Ads is available in: All versions of AdBlock

“Only allow ads without third-party tracking” is available in: All desktop versions of AdBlock


Note: If you are subscribed to this list, you won’t be able to manually block Acceptable Ads. Allowlist filters such as those in the Acceptable Ads list always override blocking filters.


EasyList

EasyList is the primary list of ad-blocking filters that the majority of ad blockers use. If EasyList is disabled, AdBlock will not be able to block ads. EasyList is enabled by default when AdBlock is installed.


EasyList is available in: All versions of AdBlock



AdBlock Custom

AdBlock Custom is the custom filter list developed by AdBlock engineers. It cleans up a few troublesome filters from EasyList and other filters that impact specific sites, and blocks ad providers that EasyList doesn't address.


Available in: All desktop versions of AdBlock and AdBlock for Firefox (Android)


Anti-Circumvention

The anti-circumvention list only blocks ads that EasyList cannot block. It uses experimental features to prevent ad blocker detection and circumvention, ad reinsertion, and other malicious techniques that advertisers and publishers use to ensure ads appear. It can be thought of as a companion list to the blocking filters available in EasyList.


Available in: All desktop versions of AdBlock


Filter Lists For Non-English Languages

If you visit websites in languages other than English, you can subscribe to filter lists for those languages (otherwise, only ads in English will be blocked). In some cases, these lists are enabled by default based on your computer’s language and location settings.


Available in: All versions of AdBlock except the AdBlock for Safari Mac app


If you need a language that's not in AdBlock’s list of language filter lists, you can find other language lists on the Adblock Plus Subscriptions page or Fanboy's Regional Lists page


To subscribe to a filter list, click the "Subscribe" link on the Adblock Plus page or the "Add List" link on the Fanboy's page and click OK. The list will appear on AdBlock’s Filter Lists page under the Custom Filter Lists section.



Other Filter Lists

I Don't Care About Cookies

I Don't Care About Cookies is the filter list we use to prevent cookie warnings from websites popping up as you browse. Cookie warnings are the notifications that many websites must get from users before installing cookies, which are used for a number of things, from advertiser tracking to maintaining your login information for you. When subscribed to the I Don't Care About Cookies filter list, you will be hiding these notifications and neither allowing nor denying permission (in most cases when the notification is hidden, the website will only install cookies that are required in order for the website to function properly.) 


Available in: All desktop versions of AdBlock except the AdBlock for Safari Mac app


AdBlock Warning Removal List

The Adblock Warning Removal list hides requests to disable ad blockers on websites you visit, but does not circumvent anti-ad blocking measures.


Available in: All desktop versions of AdBlock, AdBlock for Android


Antisocial Filter List

The Antisocial filter list removes social media buttons that track your browsing activity on web pages.


Available in: All desktop versions of AdBlock, AdBlock for Firefox (Android)


Note:

1. Subscribing to this list can break some website functionality such as links to social media sites or sign-in options that rely on Facebook or other social media. 

2. If you subscribe to Fanboy's Annoyances, it’s unnecessary to subscribe to Antisocial.


Cryptocurrency Mining Protection List

The Cryptocurrency (Bitcoin) Mining Protection List will prevent devices from being used unknowingly to mine for bitcoin or any other eCurrency by cryptocurrency miners (otherwise known as cryptocurrency mining). This list is enabled by default when AdBlock is installed.


Available in: All desktop versions of AdBlock


EasyPrivacy

EasyPrivacy is an offshoot of EasyList that prevents ads from tracking your online activities by blocking the trackers advertisers use to know what sites you visit.


Available in: All desktop versions of AdBlock, AdBlock for Samsung Internet (EasyPrivacy+EasyList), AdBlock for Firefox (Android), AdBlock for iOS


Fanboy's Annoyances

Fanboy's Annoyances blocks in-page pop-ups (the kind that prompt you to subscribe to a site's newsletter or email list), social media and related widgets, and other annoying things on web pages.


Available in: All desktop versions of AdBlock, AdBlock for Firefox (Android)


Note: 

1. As with Antisocial, enabling this list can break some website functionality that relies on Facebook and social media sign-in options.

2. If you subscribe to Fanboy's Annoyances, you don’t need to also subscribe to Antisocial.


Malware Protection

Update February 2021: The Malware protection filter list is currently unavailable. We have removed the list from the menu while we look for an alternative. 


The Malware protection filter list prevents you from accessing sites that are known to host malware. When attempting to visit these sites you’ll see an error message or the site won’t display. In order to maximize your malware protection efforts, we recommend keeping this list enabled at all times.


Available in: All desktop versions of AdBlock, AdBlock for Firefox (Android)


AdBlock for Samsung Internet

A few filter lists that you can subscribe to by URL in the desktop versions of AdBlock are available as selectable options in AdBlock for Samsung Internet:

  1. Adware filters and Malware Domains help to protect you from sites known to host adware and malware
  2. I don't care about cookies and Prebake prevent you from seeing notices about cookies on websites that use them
  3. Spam404 helps to protect you from spamming websites
