Comparing Browser Engine Security: Chromium, Gecko, WebKit

Web browsers are our primary gateway to the internet—and a significant magnet for exploits. Attackers target browsers in search of remote code execution, credential theft, or advanced side-channel leaks. In response, modern browsers incorporate multi-process architectures, robust sandboxes, memory-safe rewrites, and rapid patch cycles. This post reviews Chromium, Gecko (Firefox), and WebKit (Safari), detailing their security models and known gaps. We’ll also focus on specialized hardened forks like Vanadium (on GrapheneOS for mobile) and Trivalent (for desktop Linux), both of which significantly enhance Chromium’s baseline security features. By contrasting these engines, we get a clearer picture of what truly modern browser security can look like—and why it matters for both mobile and desktop users. ...
