Engine & ESR Base: It utilized the Firefox Extended Support Release (ESR) 102.9.0, which provided a stable foundation with backported security patches. Integrated Extensions:

NoScript 11.4.18: A critical component for preventing malicious scripts from executing and deanonymizing the user.

HTTPS Everywhere: Integrated to ensure connections to websites remained encrypted whenever possible. Key Features and Improvements

This release addressed several platform-specific bugs and introduced usability enhancements:

Multi-Locale Support: Continuing the trend from the 12.0 launch, this version allowed Windows users to change browser languages via the "General" settings menu without needing to download separate language-specific installers.

Security Hardening: It included fixes to prevent NoScript from being accidentally disabled and enabled network.http.referer.hideOnionSource to better protect the privacy of .onion site visits.

Platform Stability: It resolved issues within the Tor Expert Bundle for Windows, specifically a regression where tor.exe failed to output log messages to the console. Installation and System Requirements

Tor Browser 12.0.4 was distributed as a portable, self-contained .exe file that did not require administrative privileges to install or make changes to the Windows Registry.

OS Support: Compatible with Windows 10 and Windows 11 (both 32-bit and 64-bit architectures).

Hardware: Recommended at least 512 MB of RAM and a modern CPU, though performance improved significantly with hardware supporting AES-NI. New Release: Tor Browser 12.0.4
