Browser Support • Re: Cloudflare Verification Loop issues

You still cannot exclude that the Cloudflare tool won't get confused, if you visit certain websites with cookies set by your extension, and other websites without such cookies, still using the exact same browser from the same location.

First of all, Cloudflare check no longer works for me on any website, so I access all websites that use Cloudflare check using the add-on "Bypass Cloudflare with Backup Browser Cookies". Therefore, there is no risk for the "Cloudflare tool" to "get confused".

Second, when I use the add-on "Bypass Cloudflare with Backup Browser Cookies" with cookies taken from Firefox, those pages open directly, without triggering Cloudflare check. This behavior is identical to a scenario where Cloudflare doesn't even exist. To prove this statement, I ran some tests ( with https://www.portablefreeware.com/ ) in which I intercepted "WebRequest" using the JavaScript file "get_all_requests_for__challenges_cloudflare_com.uc.js" placed in "chrome" folder.

get_all_requests_for__challenges_cloudflare_com.uc.js

In the first test, I used MatchPattern = https://challenges.cloudflare.com/*, and in the second test, I used MatchPattern = all_urls. The test results were written to the file "challenges_cloudflare_com__requests.txt" in the new folder "requests_for__challenges_cloudflare_com" created by JavaScript in the folder "Profiles\XXXXXXX.default".

When I used MatchPattern = https://challenges.cloudflare.com/* there were no "WebRequests", and when I used MatchPattern = all_urls there were no "WebRequests" to the Cloudflare servers.

EDIT:

Important !

If you're using a Javascript file with the .uc.js "extension" in the "chrome" folder (such as "get_all_requests_for__challenges_cloudflare_com.uc.js"), you need to copy the following CSS code into "userChrome.css" file in order for the code in that Javascript file to be activated:
