## Description

Thorium is a web browser built from the Chromium project, designed for high performance and expanded compatibility. It utilizes aggressive compiler optimizations and CPU-specific instruction sets, such as AVX2 and SIMD, to increase page rendering and JavaScript execution speeds.

The project distinguishes itself by providing custom builds that enable modern web browsing on legacy versions of Windows and Linux. It further diverges from standard browser implementations by integrating Widevine DRM and native support for high-efficiency media formats, including HEVC and JPEG XL.

Broad capabilities cover privacy and security through telemetry reduction, fingerprinting protection, and Global Privacy Control. It also includes advanced multimedia features such as hardware-accelerated video decoding via VAAPI, real-time live caption generation, and native FTP protocol support.

Developer utilities are provided for resource management, application testing via automation drivers, and performance benchmarking for WebAssembly and JavaScript.
