In a significant shift reflecting the evolving landscape of online privacy, Mozilla has announced the removal of the “Do Not Track” (DNT) feature from Firefox, effective with version 135. Introduced in 2009, DNT allowed users to request that websites refrain from tracking their online activities. However, the feature’s voluntary nature led to widespread non-compliance, diminishing its effectiveness.

Mozilla’s decision underscores a broader industry acknowledgement: passive requests for privacy are insufficient. Instead, active measures are necessary to protect user data. Firefox now emphasizes tools like Enhanced Tracking Protection, which automatically blocks known trackers, and the Global Privacy Control (GPC) setting, enabling users to assert their data preferences more robustly.

This move aligns with a growing trend among browsers to implement more assertive privacy protections. For instance, Apple’s Safari discontinued DNT support in 2019, citing its ineffectiveness and potential misuse of fingerprinting.

For users, this transition means relying on more proactive privacy tools. Features like Enhanced Tracking Protection and GPC offer tangible defences against unwanted tracking, moving beyond the limitations of the outdated DNT system.

Looking ahead, Mozilla’s decision may prompt other browser developers to reassess their privacy features, potentially leading to a more standardized and enforceable approach to user data protection across the web.
