Firefox 140 Update: Privacy Features Chrome Won’t Copy

Firefox 140 brings a fresh wave of privacy-focused innovations that underscore Mozilla’s commitment to user security and data protection. Unlike other major browsers such as Chrome, Firefox continues to push boundaries by introducing features that prioritize your privacy without compromising performance or usability.

Prerequisites

A computer or device with Firefox installed (preferably upgraded to version 140 or later)
Basic understanding of web browsers and online privacy concepts
Optional: Familiarity with browser security settings

Key Privacy Enhancements in Firefox 140

This update focuses on several key areas that enhance privacy beyond what Chrome currently offers:

1. Enhanced Total Cookie Protection

Firefox 140 refines its Total Cookie Protection mechanism, which confines cookies to the site where they were created. This containment blocks cross-site tracking cookies that many advertisers use to follow your browsing habits across multiple websites.

2. Advanced Fingerprinting Resistance

Fingerprinting is a technique used to uniquely identify you based on your device and browser settings. Firefox 140 introduces new heuristics and restrictions that make fingerprinting efforts less reliable, helping protect you from being tracked covertly online.

3. Redesigned Privacy Dashboard

The update also brings a revamped Privacy Dashboard. This user-friendly interface allows you to see and manage what trackers Firefox blocks, providing insight and direct control to enhance your browsing privacy.

4. DNS over HTTPS (DoH) Updates

DNS over HTTPS encrypts your DNS queries, preventing third parties from snooping on the websites you visit. Firefox 140 broadens its support for DoH servers and improves fallback handling to maintain encrypted DNS queries even under network disruptions.

5. Enhanced HTTPS-Only Mode

You can now rely on an improved HTTPS-Only Mode that forces all connections to use secure HTTPS encryption by default, helping safeguard your data from interception or tampering.

How Firefox 140’s Privacy Stack Differs from Chrome

While Chrome has gradually introduced some privacy improvements, Mozilla aggressively pursues privacy-first features like Total Cookie Protection and fingerprinting resistance that Google has yet to replicate fully. Firefox’s open-source nature also makes transparency and community audits possible, increasing trust for privacy-conscious users.

Step-by-Step Guide to Enable New Privacy Features in Firefox 140

Update Firefox: First, ensure your Firefox browser is updated to version 140 or newer. Click the menu (three horizontal lines) > Help > About Firefox to check.
Open Privacy Settings: Navigate to Settings > Privacy & Security.
Enable Total Cookie Protection: Under Cookies and Site Data, select the option to restrict cross-site tracking cookies.
Turn on Fingerprinting Protection: Scroll to Enhanced Tracking Protection and select the Strict mode to maximize fingerprinting resistance.
Enable HTTPS-Only Mode: Turn on HTTPS-Only Mode in all windows to force encryption.
Configure DNS over HTTPS: Still under Privacy & Security, find the Network Settings section and enable DNS over HTTPS. Choose your preferred DoH provider.
Explore the Privacy Dashboard: Open a new tab and type about:protections to review and manage blocked trackers and cookies.

Troubleshooting Common Issues

Websites Not Loading Properly: Some sites relying on third-party cookies may malfunction with Total Cookie Protection. Temporarily disable strict cookie controls for that site via the shield icon in the address bar.
Slow Browsing: If the Privacy Dashboard or DoH causes lag, update Firefox and reset network settings. Network speed can impact encrypted DNS resolution times.
Compatibility with Extensions: Privacy extensions may overlap with Firefox’s built-in protections. Disable duplicates to avoid conflicts.
