What is iridium.exe?

iridium.exe is the executable for the Iridium Browser, a privacy-focused Chromium-based web browser. It uses a multi-process architecture to run tabs, extensions, and internal components in separate sandboxed processes. This design improves security, stability, and privacy by isolating tasks.

Iridium uses a multi-process architecture: a browser process manages the UI, a separate renderer process handles each tab, and additional processes manage plugins, GPU acceleration, and extensions. This separation enhances security and stability by sandboxing components from the system.

Quick Fact: Iridium began as a privacy-focused Chromium fork, aiming to reduce telemetry while preserving Chrome-like performance and compatibility.
