Firefox 69.0.1 unable to pass site with "checking your browser before accessing" It just loop with new ID every 5 seconds.

Posted

Hey guys. I don't know what is going on but Firefox on my new gaming rig is acting weird. I tried clean install Windows but no work.

Everytime I visit site that has CloudFlare DDOS protection, I can't get pass "Checking your browser before accessing xxxxxx." like animedao.com for instance. It just loop the "Checking your browser before accessing xxxxx" with new id every 5 seconds.

I tried clean install Firefox on my secondary laptop with Shadow Defender on to see if this is Firefox issue, and on my secondary laptop with SD on and clean install Firefox allow me to pass CloudFlare DDOS protection " Checking your browser before accessing xxxxx."

But on my gaming rig, I can't get pass this. Help please.

Chrome and Edge work fine with site that has Cloudflare DDOS protection but Firefox can't get pass "Checking your browser before accessing."

What is the beep code is going on?!

On my laptop, FireFox 69.0.1 can pass checking your browser before accessing xxxx site, but on my new gaming rig can't.

Clean install Windows with only motherboard, gpu, and Windows Updates installed. I clean install FireFox with no extensions or any browser settings modified. No 3rd party AV.

Cloudflare uses a cookie based challenge. The website creates a cf_clearance cookie when the challenge is resolved and the check finishes properly.

FF at default settings can't pass browser checking on my new gaming rig. Do you have a solution for it? The browser checking will loop forever with new Ray ID every 5 seconds. I can't access the site without passing this browser check from CloudFlare.

No problem here with Firefox 69.0.1 and some standard setting changed (blocking third-party cookies), but I'm not using any content blocking extensions. It takes about 5 seconds for the challenge to finish and make the website appear. If this isn't working then you possibly have an extension or your security software interfering. If you check the page source then you will notice that a form is created and submitted for this challenge.

My Firefox 69.0.1 on my gaming desktop will never pass this browser check on any sites that have CloudFlare DDOS browser check. It will loop over and over with the new Ray ID. I don't have any extensions installed or did any changes to the browser. I just simply installed the browser then went to animedao.com or other sites with this browser check for DDOS.

On my laptop, I can access sites with browser check for DDOS fine. I also did not make any changes to the system settings on my gaming desktop at all. No 3rd party antivirus at all. This is a second install Windows with motherboard drivers, graphics card driver, and Windows Updates installed.

I have waited for more than 10 minutes on animedao to pass this browser check, and it still looping every 5 seconds.

Chrome and Edge work fine but FireFox doesn't so what sup? I don't know this is OS issue because Chrome and Edge were not affected.
