Adblock Plus is a free extension that allows you to - among other things - block annoying ads, disable tracking and block domains known to spread malware.
Available for Chrome, Firefox, Internet Explorer, Maxthon, Opera, Safari and Yandex, Adblock Plus uses filters that you choose to block all unwanted elements.
Adblock Plus itself has no functionality; it doesn't block anything until you "tell" it what to block by adding external filter lists. Filter lists are essentially an extensive set of rules that tell Adblock Plus which elements of a website to block. More Info »
You can add any filter list you want. For example, block tracking or malware. You can also create your own filter lists. Almost all filters are open source, therefore many filter lists have been created by Internet users.
Filter lists enabled by default include:
An ad-blocking list selected based on your language (EasyList)
The Acceptable Ads list
These are enabled to get you started. You can remove them or add others - it's up to you.
EasyList corresponds to your browser language and is aimed at disabling ads that are considered to be intrusive by our community of users. Eyeo GmbH did not draft EasyList and therefore has no right to, or control over, its content. Visit the EasyList Community for more information.
The Acceptable Ads list displays ads that comply with the acceptable ads criteria agreed upon by our community of users. The list is maintained by Eyeo GmbH. More Info »
