Mozilla to Remove 'Do Not Track' Feature from Firefox in February 2025

The privacy setting, introduced in 2009, is being replaced by Global Privacy Control due to its ineffectiveness and misuse.

Mozilla plans to eliminate the 'Do Not Track' (DNT) feature from Firefox starting with version 135, set for release on February 4, 2025.
DNT, initially designed to signal websites not to track users, was widely ignored by websites and sometimes misused for browser fingerprinting.
Mozilla recommends users switch to the 'Tell websites not to sell or share my data' setting, which is based on the Global Privacy Control (GPC) standard.
GPC has gained more traction due to enforcement under laws like California’s Consumer Privacy Act and the EU’s General Data Protection Regulation.
Other browsers like Apple’s Safari removed DNT years ago, and Mozilla’s decision reflects a broader shift toward more enforceable privacy measures.
