Re: Cloudflare Verification Loop issues
well, cloudflare checks seem to be working for me, but the turnstile check causes the browser serious problems at step 6 and then fails with
Security Check Failed
An unexpected error occurred with the security check.
Error: 300030 (Unknown)

It has been explained why the Turnstile Troubleshooter fails. Forget about it.

Re: Cloudflare Verification Loop issues
Might as well drop this here: lots of these Cloudflare checks infest PM with heavy scripts which don't get properly flushed from the system, and overtime pile up to cause slowness. Source: my intuition (it came to me in a daydream).

Re: Cloudflare Verification Loop issues
i'd prefer it didn't cause the browser to lock up for 5 to 10 seconds - which has not been explainedback2themoon wrote: ↑2026-04-11, 16:41It has been explained why the Turnstile Troubleshooter fails. Forget about it.

Re: Cloudflare Verification Loop issues
I am quite clearly talking about the single, dedicated page that's meant for testing alone. Do you really need THAT to work for some reason?
I can only guess that you might be talking about the standard CF check on all websites that use it. On some websites it does take longer indeed. In general, it seems slower than their previous working version, even though on some websites it remains fast. You can only blame Cloudflare for that.

Re: Cloudflare Verification Loop issues
The same lock up / freeze up happens on at least one website I use the same as the turnstile does and the effect persists so long as that website is open even after I've navigated away from the page with the check on it.
It's the only one out of maybe 5 sites I've checked since the fix was implemented, so it's 1 out of 5 for me that does this. The freeze / lock up happens while the CF check is "Verifying" and then even after I've passed the check, the browser is sluggish and periodically freezes for a few seconds every few seconds until that page is closed. The turnstile page does a similar thing.

Re: Cloudflare Verification Loop issues
It's been the way for us (devs) to check and discuss their API checks and work on getting to something we agree on. So it's not important for end users but it is important for coming to an agreed-upon feature set that is significantly difficult for bots to mimic.back2themoon wrote: ↑2026-04-12, 09:51am quite clearly talking about the single, dedicated page that's meant for testing alone.

So it does need to get solved for their scripting to work on Pale Moon without special carveouts

Re: Cloudflare Verification Loop issues
I was lucky enough to not hit this issue the past time(s) it popped up, but a small private forum I use just had to enable further protections after getting absolutely hammered with bots, and so I'm stuck in loopsville there. My sincere thanks to everyone who's attempting to deal with Cloudflare's nonsense and hopefully get things resolved.

Re: Cloudflare Verification Loop issues
Cloudflare fixed the problem on their end about a week ago, you shouldn't be having this problem right now.Top Gun wrote: ↑2026-04-18, 16:28I was lucky enough to not hit this issue the past time(s) it popped up, but a small private forum I use just had to enable further protections after getting absolutely hammered with bots, and so I'm stuck in loopsville there.

Apparently the fix didn't take for everything, or a new issue cropped up, because I was seeing that exact same looping behavior just this afternoon.andyprough wrote: ↑2026-04-18, 18:48Cloudflare fixed the problem on their end about a week ago, you shouldn't be having this problem right now.

Re: Cloudflare Verification Loop issues
Is that still on that one small forum that you reported was causing the endless loop? Could be that they have incorrect Cloudflare settings. I don't think we've seen another report like this all week in the forum by anyone on the current version of Pale Moon. You might want to try Pale Moon on that site with a clean profile and no extensions, or at least try clearing your cache and the cookies for that site.Top Gun wrote: ↑2026-04-19, 03:01Apparently the fix didn't take for everything, or a new issue cropped up, because I was seeing that exact same looping behavior just this afternoon.andyprough wrote: ↑2026-04-18, 18:48Cloudflare fixed the problem on their end about a week ago, you shouldn't be having this problem right now.

Re: Cloudflare Verification Loop issues
I'm not sure if the site changed their settings, but I stopped getting the Cloudflare verification page entirely later in the day. If it pops up again I'll try those suggestions. I don't really want to bother the site admin about it otherwise, since he's one guy hosting a site for a bunch of oldhead nerds and he's doing the best he can against the bot onslaught.andyprough wrote: ↑2026-04-19, 04:06Is that still on that one small forum that you reported was causing the endless loop?

Re: Cloudflare Verification Loop issues
I'm thinking he may have just had the Cloudflare settings wrong. Probably takes awhile to get used to the settings when a site admin first starts using it, and then finds that he has to adjust them as the complaints start rolling in from members who can't access it.Top Gun wrote: ↑2026-04-19, 05:18I'm not sure if the site changed their settings, but I stopped getting the Cloudflare verification page entirely later in the day.

I just got the same. 3 different CF challenges crash the browser completely.

Re: Cloudflare Verification Loop issues
Confirmed on Linux as well. I would say so much for them trying to have a positive relationship with us, but it's possible they've exposed an actual bug in UXP that needs to be fixed.
