Cloudflare has been blocking "mainstream" browsers too, if you are generous enough to consider Firefox "mainstream." The "verify you are a human" sequence gets stuck in a perpetual never-ending loop where clicking the checkbox only refreshes the page and presents the same challenge. Certain websites (most notably archive.is) have been completely inaccessible for me for years for this reason.

I'm using chrome on linux and noticed that this year cloudflare is very agressive in showing the "Verify you are a human" box. Now a lot of sites that use cloudflare show it and once you solve the challenge it shows it again after 30 minutes! What are you protecting cloudflare? Also they show those captchas when going to robots.txt... unbelievable.

Cloudflare has been even worse for me on Linux + Firefox. On a number of sites I get the "Verify" challenge and after solving it immediately get a message saying "You have been blocked" every time. Clearing cookies, disabling UBO, and other changes make no difference. Reporting the issue to them does nothing. This hostility to normal browsing behavior makes me extremely reluctant to ever use Cloudflare on any project…

Yeah, Lego and Etsy are two sites I can now only visit with safari. It sucks. Firefox on the same machine it claims I'm a bot or a crawler. (not even on linux, on a mac)

A lot of people are failing to conceive the danger that poses to the open web the fact that a lot of traffic runs through/to a few bunch of providers (namely, CloudFlare, AWS, Azure, Google Cloud, and "smaller" ones like Fastly or Akamai) who can take this kind of measures without (many) website owners knowing or giving a crap about. Google itself tried to push crap like Web Environment Integrity (WEI) so websites co…

I can easily conceive the danger. But I can directly observe the danger that's causing traffic to be so centralized - if you don't have one of those providers on your side, any adversary with a couple hundred dollars to burn can take down your website on demand. That seems like a bigger practical problem for the open web, and I don't know what the alternative solution would be. How can I know, without incurring any n…

Exactly. If you're going to bemoan centralization, which is fine, you also need to address the reason why we're going in that direction. And that's probably going to involve rethinking the naive foundational aspects of the internet.

I run a honeypot and I can say with reasonable confidence many (most?) bots and scrapers use a Chrome on Linux user-agent. It's a fairly good indication of malicious traffic. In fact I would say it probably outweighs legitimate traffic with that user agent. It's also a pretty safe assumption that Cloudflare is not run by morons, and they have access to more data than we do, by virtue of being the strip club bouncer f…

User-agent might be a useful signal but treating it as an absolute flag is sloppy. For one thing it's trivial for malicious actors to change their user-agent. Cloudflare could use many other signals to drastically cut down on false positives that block normal users, but it seems like they don't care enough to be bothered. If they cared more about technical and privacy-conscious users they would do better.

I mean, do we need to replace user agent with some kind of 'browser signing'?

Cloudflare is actually pretty upfront about which browsers they support. You can find the whole list right in their developer docs. This isn't some secret they're trying to hide from website owners or users - it's right here https://developers.cloudflare.com/waf/reference/cloudflare-c... - My guess is that there is no response because not one of the browsers you listed is supported. Think about it this way: when a fr…

Not exactly. They say: "Challenges are not supported by Microsoft Internet Explorer." Nowhere is it mentioned that internet access will be denied to visitors not using "major" browsers, as defined by Cloudflare presumably. That wouldn't sound too legal, honestly. Below that: "Visitors must enable JavaScript and cookies on their browser to be able to pass any type of challenge." These conditions are met.

> * If your visitors are using an up-to-date version of a major browser * > * they will receive the challenge correctly. *

I'm unsure what part of this isn't clear, major browsers, as long as they are up to date, are supported and should always pass challenges. Palemoon isn't a major browser, neither are the other browsers mentioned on the thread.

> * Nowhere is it mentioned that internet access will be denied to visitors not using "major" browsers *

Challenge pages is what your browser is struggling to pass, you aren't seeing a block page or a straight up denying of the connection, instead, the challenge isn't passing because whatever update CF has done, has clearly broken the compatibility with Palemoon, I seriously doubt this was on purpose. Regarding those annoying challenge pages, these aren't meant to be used 24/7 as they are genuinely annoying, if you are seeing challenge pages more often than you are on chrome, its likely that the site owner is actively is flagging your session to be challenged, they can undo this by adjusting their firewall rules.

If a site owner decides to enable challenge pages for every visitor, you should shift the blame on the site owners lack of interest in properly tunning their firewall.

Sure, but does that means that we, Linux users, can't go on the web anymore ? It's way easier for spammers and bots to move to another user agent/system than for legitimate users. So whatever causes this is not a great solution to this problem. You can do better CF

I'm a Linux user as well but I'm not sure what Cloudflare is supposed to be doing here that makes everybody happy. Removing the most obvious signals of botting because there are some real users that look like that too may be better for that individual user but that doesn't make it a good answer for legitimate users as a whole. SPAM, DoS, phishing, credential stuffing, scraping, click fraud, API abuse, and more are problems which impact real users just as extra checks and false positive blocks do.

If you really do have a better way to make all legitimate users of sites happy with bot protections then by all means there is a massive market for this. Unfortunately you're probably more like me, stuck between a rock and a hard place of being in a situation where we have no good solution and just annoyance with the way things are.

Things like "using Linux" or "having an adblocker at all" get you sent to captcha hell. Anything where you're in the minority of traffic. It's not going to change; why would it?

I have multiple blockers (Ublock Origin, Privacy Badger, Facebook Container) in Firefox and have not experienced this issue.

For what it's worth, this has been my experience as well. I've seen maybe a handful of full-page Cloudflare walls over the past year, and none have gotten me stuck in any kind of loop
