#2I mean, with that market share, popularity among open source fans... it's an easy group to target and filter oddballs.
I'm a Firefox user and I'm used to this treatment at every step of the way, no matter if it's about software, airports, opening a bank account so I can receive a salary, etc. Fundamental things everyone wants to do are being made hard to do the right way. It's always anti privacy, anti self repair, anti longevity/sustainability, anti user freedoms, anti whatever we ideally want in this world. Of course using Firefox is now suspicious.

#3I'd be curious to see if this is the case for other sites that use Cloudflare bot protection as well. There are a bunch of ways to tune the service so maybe they are just extra cautious?

#5Incredible. I just changed my user-agent whilst on the Google Chrome browser.
* Changing to Firefox immediately displayed the Cloudflare error message
* Edge had no errors
* Chrome had no errors
* Safari had no errors
Edit 2: as another user has pointed out, this is most likely a firewall rule put in place by the website operator themselves.

#6Cloudflare uses a lots of heuristics to determine whether to show their challenge. In fact getting served a challenge says more about the amount of bot traffic that the website is getting than about how bot-like you look.

#7I can’t reproduce what this article is claiming, even using a completely new profile. I’m only a size of one for this perspective though.

#8A workaround is to install the Privacy Pass extension to bypass the captchas [1] [2]
It's an open source extension available for Chrome and Firefox. It allows to privately identify you're human, and is the process of going through IETF standardisation, so hopefully someday you won't need to install an extension for it. After you complete a captcha once, you won't need to do it again for a long time.
I'm not happy about installing extensions just to view some websites, but it'll make things less painful

#9I think it's two-fold: rise of tools like curl-impersonate (https://github.com/lwthiker/curl-impersonate) and the very consistent Firefox TLS fingerprint across platforms. Unlike Chromium (where you could differentiate a Linux, Mac or Windows computer from its chiphers, and so for example challenge only Linux clients), Firefox has NSS and NSS is used everywhere the Gecko engine is used while Chromium, although has BoringSSL for modern chiphers, also uses the underlying TLS stack of the operating system (whether it's Microsoft's SChannel, Apple's SecureTransport or Linux's... NSS). The only time Chromium uses a pure BoringSSL implementation is on Android (Conscrypt).

Do you see the error when testing with Firefox, though?
Receiving a "you look like a bot" message when using Chrome configured to pretend to be Firefox isn't very surprising.
