Hi,

Here are some standard troubleshooting steps that may resolve the issue. Please fell free to skip those that you have already tried.

  1. Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield Fx89ShieldIcon icon at the left of the address bar.
    • If ETP is enabled, try disabling it.
  2. If the problem is not fixed, try clearing Firefox cache.
  3. If it does not help, also try clearing cookies and data for the website you experience troubles with (warning: you will be logged out on this website).
  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.

Looking forward to your update on how it goes!
