It is no secret that Mozilla makes a lot of efforts to provide users of the proprietary Firefox browser with the highest level of security when working on the Internet. It was announced today that the new Firefox 87 will automatically strip information from the URL to track certain user activity.
Browsers usually send HTTP referrers to tell the website where the user was directed from. Sites can use this information for many innocent purposes, including analytics, logging, or cache optimization. However, it is quite common for HTTP referrers to contain the user’s data. For example, they can show what content a user is viewing on the referring website and even include information about their account.

Since 2016, when the widespread abandonment of the HTTP protocol in favor of the more secure HTTPS began referrers have become less of a threat, but under certain conditions it is still possible to get quite a lot of user personal data from them. The new “strict-origin-when-cross-origin” policy introduced in Firefox 87 completely strips any personal user information from the URL making surfing the web much more anonymous and secure.
The best part is that the user doesn’t have to take any action to take advantage of the new opportunity. In Firefox 87, the new policy is applied by default.
