Reintroducing the $ping filter option · 2015-12-23 16:59 by Sebastian Noack
Historically, there has been the
$ping filter option in Adblock Plus, to limit request blocking filters to the URL given by the ping attribute on links. When such a link is clicked, the browser sends a request to that URL in the background. This technique is mostly useful for tracking. However, it has never been enabled by default in Firefox. Therefore, with Adblock Plus 2.0,
$ping got deprecated and merged into
ping HTML attribute. And it is enabled by default. Moreover, on Chrome,
<a ping> is supported by default too. And starting with Chrome 49, it’s possible to distinguish these requests from others.
Therefore, we are reintroducing the
$ping filter option (issue 3452). Starting with Adblock Plus 220.127.116.1199 for Firefox and 18.104.22.1688 for Chrome/Opera, filters using the
$ping option will only match requests that are either caused by
<a ping> or by
navigator.sendBeacon(). Note that the filter option
$other won’t match these requests anymore.
