Mozilla plans to enable Hyperlink Ping Tracking by Default in Firefox

[harlan4096]

A new Bleeping Computer report by Lawrence Abrams suggests that Mozilla plans to enable Hyperlink Ping Tracking by default in the Firefox browser.

Firefox is one of the few browsers that has the feature disabled by default, another is Brave. Most Chromium-based browsers, Google Chrome and Opera, as well as Microsoft Edge and Safari have the feature turned on by default.

The browsers that have the feature enabled already won't allow users to disable the feature anymore in coming versions. Chrome users, for example, can disable Hyperlink auditing in the browser currently on chrome://flags if they run the Stable version. Chrome users who run Beta or other development versions won't find the feature listed anymore as Google removed it from the list of available flags.

What is Ping Hyperlink Auditing?

Links, or hyperlinks, are a fundamental HTML feature that loads another resource when a user activates it.

Ping is a new attribute that can be added to links to send information to another resource. Here is an example: <a href="https://www.ghacks.net/ ping="https://www.example.com/">This</a>

When a user clicks on the Ghacks Link, Example.com is notified that the click happened. It is possible to notify one or multiple resources about the link click.

What is bad about it?

Ping is used to track link clicks. The nature of how that is done is not transparent to users who click on links, as the ping attribute is not shown and links with pings are not highlighted when a user hovers over the link in the browser.

While it is possible to check the source, it is not comfortable and unlikely that many users will do so.

Apart from privacy, at least one case has been recorded where pings were used for denial of service attacks.
