Is it the same if you sign in via a separate Private Window?

Normally I'd suspect a VPN or security/antivirus software like Norton and similar to be stalling connections, but you might have some success trying these first:

  1. Start with clearing Firefox cache.
  2. If it does not help, try clearing cookies and data for the website you experience troubles with (warning: you will be logged out on this website).
  3. Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield Fx89ShieldIcon icon in the left part of the address bar. If ETP is enabled, try disabling it.
  4. If it also does not help, try running Firefox in Troubleshoot Mode. If the problem doesn't persist, please follow the steps from this article to troubleshoot further.
  5. If nothing from the above helps, try creating a new Firefox profile and check if the issue persists there. If it doesn't, you can start copying files from your old profile to the new one to identify which one causes the issue. See this article on what files to copy.
