Thorium

Thorium is a Chromium‑based web browser that runs on Linux, macOS, Windows, Android, and Raspberry Pi. It incorporates a series of compiler optimizations—such as SSE4.2, AVX, AES, PGO, and LLVM loop flags—to improve execution speed, delivering an 8‑38 % performance gain over standard Chromium depending on the benchmark and operating system. The project also applies patches that modify the user interface, fix bugs, and enhance privacy and security, including a toggle for dark or light mode.

The browser targets users who need a fast, cross‑platform web client and who value the ability to customize the experience through extensions and themes. Its repository supplies pre‑built packages for distributions that support .deb, and a dedicated install script automatically adds the Thorium source list and updates the software.

Beyond the core browser, Thorium’s ecosystem includes a range of community‑maintained extensions—such as a system monitor, scroll‑speed tweaker, picture‑in‑picture viewer, and resource saver—allowing users to extend functionality without leaving the browser environment.
