It of, but variations of Opera, Safari and Chrome have been in the process of taking away the capability to disable a long-ignored monitoring feature called hyperlink auditing pings. This is a long-established HTML feature that’s set as an attribute — that the ping variable — which turns out a link into a URL that may be tracked advertisers or by site owners to monitor what users are clicking on. When a user follows a link set up to work like this, an HTTP POST ping is delivered without revealing that this has occurred to another URL which records this interaction. It’s only one of many ways users can be monitored, clearly, but it has long bothered privacy experts, which is the reason why third party adblockers include it by default on their block list.

Until now, an even simpler way to block those pings has been via the browser itself, which in the event of Chrome, Safari and Opera is carried out by placing a flag (in Chrome you kind chrome://flags and set hyperlink auditing to’disabled’). Notice, however, these browsers nevertheless enable hyperlink auditing by default, which means users would need to understand about this setting to alter that. It appears that very few do.
