DDoS protection by Cloudflare infinite loop only on Firefox
every time that I am trying to access a website that is protected by DDoS protection from Cloudflare, I get stuck in an infinite loop of "Checking your browser before accessing" and than the page is reloading itself and i get a new Ray ID. It only happens on Firefox in other browsers I can access Cloudflare protected websites... I tried to disable my antivirus and safe mode in Firefox also tried to refresh Firefox and a new installation (tried Official release and beta release)...
I have added the Troubleshooting Information

Can you post the link before the login so others can see if they get the same results clicking on it.

This could be cookie related, so make sure that you do not block cookies. you can also check the connection settings in Options/Preferences.
Did you try a completely clean profile (a refresh can carry over issues as it imports data)?
You can create a new profile to test if your current profile is causing the problem.
See "Creating a profile":
- https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
- http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
Do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware. All these programs have free versions.
Make sure you update each program to get the latest version of their databases before doing a scan.
