This video provides an in-depth analysis of the technical architecture and market status of the Chromium browser core. Chromium is an open-source browser project led by Google, comprising three core modules: the Blink rendering engine, the V8 JavaScript engine, and the base UI. Its total code volume reaches 40GB. Currently, over 85% of browsers on the market are built on Chromium, including mainstream products like Chrome, Edge, Brave, and Opera. The video elaborates on the technical differences between Chromium and non-Chromium browsers (such as Firefox and Safari), focusing on the impact of Google's Manifest V3 update on ad-blocking functionalities, and touching upon ecological issues arising from Chromium's dominance. It also recommends quality browser choices like Brave, Vivaldi, Waterfox, and Zen that balance privacy protection and performance, assisting users in selecting the most suitable browsing tool based on their needs.
