Earlier quoted context omitted.
Fingerprinting is one of the techniques used to track you across the web. If the site is serving Google, Meta, or ads from other networks, your unique browser fingerprint is one of the tools that makes it possible to target and retarget you.
I think we’re all aware of that. Where’s the specific evidence that Chrome passed the Cloudflare DDOS protection because it gave up more private information than Firefox did?
I think the fingerprinting is a red herring. Yes, Chrome is less secure. But Chrome worked.
It's quite possible someone at the author's workplace updated their Cloudflare WAF settings and made things more strict, causing more checks. I'd even offer that a Firefox extension might be contributing.
But the argument that Chrome worked because it offered Cloudflare personal information is pretty out there ;)
