How Are Current Browsers Behaving Against BrowserAudit Tests?

[Renk]

I just tested some current browser on the site browseraudit.com. I used a VM with W10 Enterprise as OS.



Here are the results I got:


Ungoogled Chromium 88
Edge 89
Brave 1.22.19 (chromium 89 (nightly))
passed: 367
skipped: 20
Warning: 16
critical: 1


TorBrowser(v 10.0.12 based on FF 78.8 ESR) standart security level
passed: 364
skipped: 26
warning: 14
critical: 0


JonDoBrowser (based on FF ESR 52)
passed: 374
skipped: 20
warning: 9
critical: 0


FF 86 hardened with ArkenFox userjs (no addons)
passed: 375
skipped: 20
warning: 9
critical: 0


Genuine FF 86 (no customisation)
passed: 376

As you can see, there isn't a lot of variety in browser engines these days...

Anyway, last time I ran BrowserAudit, most of the warnings either were largely inconsequential or couldn't be addressed without making the browser fingerprint more unique. What was that critical error for Chromium, though?
