Disable hyperlink auditing beacon
For those browsers, the network requests fired as a result of calling
navigator.sendBeacon() are sent as behind-the-scene network requests.
Caveats for browsers based on Chromium version 48 or less
Network requests created as a result of web pages using
navigator.sendBeacon() will not be blocked when the setting "Disable hyperlink auditing/beacon" is checked. This is a limitation of the chrome API prior to v49, as network requests fired as a result of calling
navigator.sendBeacon() are reported as the generic type
other by the browser.
The webRequest API was extended in Chromium 49 to support new request types, and thus the setting works fine for any browser based on Chromium 49 or higher, as there is now a specific network request type,
ping, which uBO normalizes to
beacon -- and hence can now filter correctly.
