Users want to chrome hegemony and don't care about the open web or Firefox. Its the number #1 browser on desktop even though it doesn't come with the OS. Windows comes with edge and macs come with safari. Users have to download Chrome.

All browsers so far have come and gone in popularity. Even when it seemed unimaginable.

But today everything but Firefox is Chromium.

That's a little different

Hi there, I'm the PM for Cloudflare's challenge platform. I'd love to look into what the cause of the problem is, so you don't see these difficulties. > Cloudflare detected the high frequency of requests and denials (but not their faulty loop that caused this pattern of requests, of course), and tagged my browser as suspicious. I can tell you at least that we don't penalize users for this looping behavior, so this wo…

Anecdotaly... I use Firefox and have noticed the Cloudflare interception pages verifying I'm human appearing more often recently. Usually it is all automatic and isn't a big deal, but I have noticed a increase in how often I see these the past week.

I use a VPN 99% of the time and I definitely see more cloudflare on my systems (as opposed to when I'm bored and surfing in the library) and see the "checking" screen. It does seem to be a lot better than last year though when it seemed I was getting a captcha every time I turned around

I've had the exact same problem for a while. Here are some of the sites I've been unable to access (found by searching for "just a moment" in my browser history): - https://gitlab.com/users/sign_in - https://steamdb.info/login/ - https://www.zabbix.com/forum/ - https://casetext.com/ - https://namemc.com/login - https://spinroot.com/ - https://camelcamelcamel.com/ It's really annoying and Cloudflare is apparently doin…

I see the "are you human" on there with a click, but no looping, it goes straight to the website

The amount of times Cloudflare is making me sit through their 15 to 30 second "checking your connection" page is insane. For people going through life with ADHD such as myself, the impact of all these delays and disruptions throughout the day can be severe. Despite being properly medicated this measure is absolutely debilitating and makes for a dreadful and very taxing online experience.

Cloudflare's Privacy Pass may help here: https://privacypass.github.io/

It should significantly reduce the amount of CAPTCHAs you see in a way that's not terrible for privacy.

For Safari, you can enable Private Access Tokens: https://blog.cloudflare.com/how-to-enable-private-access-tok...

Both of these mechanisms are similar to Google's web DRM proposal in that they rely on external issuers to generate tokens, but unlike Google's attempt they don't guarantee that ad blockers are disabled on pages that try to use tokens.

Sadly, the fact a given site works for you or me is no guarantee it works for someone else. These bot detection systems tend to use all manner of imprecise statistical heuristics and weird fingerprinting. Perhaps AegirLeet has a graphics card that a popular web scraper pretends to have. Maybe they're in a suspicious timezone. Maybe they've installed a font usually only found on a different operating system. Maybe I'm…

Fingerprinting is scarily accurate now, strangely. https://fingerprint.com/

yeah, starting that that invisible pixels and cookie tracking are way in the past and unless you're using something like tor (and not changing the resolution) then they know who you are. I mean you can still block ads and cookies, but I figure they really do know who you are.

This is a bit tangential to the author's point but it does seem to indicate that IPv6 is mostly pointless for human users for exactly this reason. Since it's so much easier to hide behind a new unique address, compared to IPv4, that any service such as Cloudflare would need to be extremely aggressive in blocking to meet their internal metrics and customer advertised minimum thresholds. So much so that it actually cos…

> any service such as Cloudflare would need to be extremely aggressive in blocking

Cloudflare needs an algorithm to deduce the IPv6 prefix size controlled by a given entity, but the details of that algorithm are not obvious. You are jumping to the conclusion that they must be doing a bad job because the problem is challenging.

IPv4 abuse detection is also challenging because of (e.g.) the prevalence of CGNAT with multiple users sharing an IP address.

Which problem is harder? Which solution is better? I don't know, without a lot of proprietary data and analysis.

Just yesterday I realized that I couldn't log into Paypal on Safari or Firefox, only a Chromium-based browser. We're getting deeper all the time into "this site is best viewed in Google Chrome".

I have this on Twitch. I can't log in with Firefox + fingerprint resistance. Apparently 2FA isn't strong enough for account protection, I have to let Twitch uniquely identify my computer or it won't let me log in.

I just stopped watching Twitch streams.

You're basically saying this behavior is acceptable and should be considered normal and should be expected to become the norm. If you think IPv6 is mostly pointless, I think you're unaware of the fact that a significant majority of phones already use IPv6 most of the time they're on cellular.

Last time I checked when I hotspotted my T-Mobile (US) phone, hotspot clients got only an IPv6 address, with 6to4 [edit: no, NAT64] translation used to reach IPv4 addresses.

This breaks OpenVPN, which insists on both endpoints being one or the other.
