Privacy Browser includes four common filter lists based on the Adblock syntax: EasyList, EasyPrivacy, Fanboy’s Annoyance List, and Fanboy’s Social Blocking List. These filter lists are processed by Privacy Browser into the following 22 sublists, which check resource requests in the order listed.
初始列表检查 URL 的开头。最终列表检查 URL 的末尾。域列表仅检查某些域。第三方列表仅在请求的根域与主 URL 的根域不同时才适用。正则表达式列表遵循正则表达式语法。 每个子列表项都有一个或多个条目。在域子列表的情况下，如果第一个条目与主 URL 的域匹配，则仅根据项目检查资源请求。
Because of limitations in Android’s WebView, and to speed up processing of requests, Privacy Browser implements a simplified interpretation of the Adblock syntax. This can sometimes lead to false positives, where resources are allowed or blocked in ways that weren’t intended by the original entry. A more detailed description of how the filter list entries are processed is available at stoutner.com.
Privacy Browser has three additional filter lists.
UltraList and
UltraPrivacy
filters ads and trackers that EasyList and EasyPrivacy do not. The third blocks all third-party requests.
A request is only considered third-party if the base domain of the request is different than the base domain of the URL.
For example, if www.website.com loads a picture from images.website.com,
this is not blocked as a third-party request because they both share the same base domain of website.com.
Blocking all third-party requests increases privacy, but this filter list is disabled by default because it breaks a large number of websites.
