Chrome and anti-fingerprinting: Why Edge, Firefox and Brave may give trackers a harder time

Google Chrome remains the world’s most-used browser, but a new privacy analysis argues it still offers limited built-in defenses against fingerprinting compared with rivals such as Microsoft Edge, Mozilla Firefox and Brave.

The report, published by privacy researcher That Privacy Guy, focuses on how browsers handle fingerprinting, a technique that can identify users by combining small signals from their device and browser setup.

Fingerprinting can draw on details like graphics rendering, installed fonts, audio processing and other system characteristics to create a profile that may persist even when users block cookies or clear browsing data.

How fingerprinting works in practice

The analysis highlights common web APIs that can be used for fingerprinting, including canvas, audio and WebGL, and argues Chrome does not meaningfully restrict or standardize the outputs by default.

Because modern browsers also manage logins, saved passwords, syncing and site permissions, privacy researchers warn that tracking at the browser level can be harder to spot than more overt threats.

What competing browsers do differently

Firefox includes an optional anti-fingerprinting approach through the resistFingerprinting setting, which aims to reduce uniqueness by standardizing certain behaviors and values exposed to websites.

Brave takes a different approach with its built-in Fingerprinting Protection, including techniques such as farbling that can randomize some outputs while keeping pages usable.

Microsoft Edge emphasizes its Tracking Prevention controls, which can limit certain trackers and related behaviors, though the effectiveness can depend on the chosen protection level and the sites a user visits.

Privacy trade-offs still shape Chrome

The report lands as Google continues to face scrutiny over web privacy changes, including its evolving approach to third-party cookies in Chrome and the broader Privacy Sandbox effort.

For users concerned about fingerprinting specifically, the practical takeaway is that switching browsers or enabling privacy-focused settings may reduce exposure, though no mainstream browser can eliminate tracking entirely.
