I recently tested my browser with the online utility "BrowserAudit" found under...
https://browseraudit.com/
Which says...
"How secure is your browser? BrowserAudit checks that your web browser correctly implements a wide variety of security standards and features."
The online utility highlights that it was created by the "Department of Computing at Imperial College London".
OK, so here's what I did...
I compiled my browser with three different versions of the Chromium Engine, while all else being exactly the same. They were:
1. v65.0.3325.181
2. v74.0.3729.131
3. v83.0.4103.116
And here are the BrowserAudit results...
Unfortunately, it appears that the Chromium engine’s security is getting worse and worse with every release!
So much for Google and others, encouraging everyone to always upgrade to the latest version of their browser because it's “safer”!
Of course, Google isn't the only one using this junk rendering engine... there are probably three dozens browsers on the market using the same.
