70% of Chrome is made using latest Chromium source. why are you changing the topic? We all know what Chrome is and what Chromium is, but you seem to not know. Chrome uses Chromium to build and MAJORITY of Google Chrome, the vast majority of code, is Chromium In September 2008 both Chromium and Chrome were 100% identical source code , not 70% like now, but 100% : > Google Chrome was introduced in September 2008, and along with its release, the Chromium source code was also made available. https://en.wikipedia.org/wiki/Chromium_(web_browser) Nearly ALL remaining existing browsers are majority of source code based on Chromium, and Chromium is of course written by Apple in 2013 (WebKit) from Safari Basically millions of lines of Safari code are in nearly all web browsers because only Apple chose to be WWW consortium fully compliant and be the only browser to pass all WWW standards tests. It was easier to give up and use apples fast source code than to fix thousands of bugs to meet WWW rules. I used NO WRONG TERMS in the post entry you are trying to criticize. The exact spelling is and was : > **Chrome source code tree is a Dumpster Fire! Chrome 89.0.4389.72, released by Google for Windows, Mac, and Linux this week, comes with a total of 47 security fixes. One exploit is critical to patch. WARNING!** That is clear and factual. Whether the bug is ALSO in chromium is unknown until binary diffs are made and leaked before next patches and uploads to Chromium itself. The bug is secret still after two whole weeks, so now its 75% likely a bug in all browsers based on WebKit or Chromium.
