Mozilla Firefox removes "Do Not Track" Feature support: Here's what it means for your Privacy

[branfont]

Mozilla is removing the Do Not Track (DNT) setting from the Firefox browser. This change will take effect in version 135 and beyond, where the DNT setting will no longer be available. The change is already live and can be seen in the Nightly version.

Do Not Track (DNT) is a browser setting that allows users to signal their preference not to be tracked by websites. When enabled, it sends a special HTTP header to websites indicating the user’s choice to opt out of tracking.

According to Wikipedia, DNT was introduced in 2009 by researchers Christopher Soghoian and Sid Stamm, and Mozilla Firefox was the first browser to implement this feature.

However, as we approach 2025, with growing concerns about online privacy and data protection, Mozilla believes that DNT is no longer an effective privacy measure. Many websites ignore the DNT signal. Therefore, Mozilla has removed the DNT signal from Firefox version 135.

We verified the Nightly build’s “Website Privacy Preferences” and confirmed that the option to “Send websites a ‘Do Not Track’ request” is no longer present. This is also confirmed by the bug “Remove DNT control from about:preferences#privacy.”
