Resource filter compatibility data

Build Status

It is based on the mdn-browser-compat-data JSON schema (see also docs on MDN) and is being used in rendering compatibility tables at which are based on MDN's table rendering script.

The data contained in this repository is still incomplete and may contain various inaccuracies so please take it with a grain of salt. Furthermore, Mozilla warns that the data format's structure is subject to change without notice.

Repository contents

Supported ad blocker identifiers

Further notes

  • mdn_url is used to point to the canonical documentation for a feature. In case there are multiple divergent implementations, none is specified.
  • Since most other ad blockers look for compatibility with Adblock Plus' features, the status properties (e.g. standard_track) refers to Adblock Plus' implementation.
