Hi there,

Sorry to hear that the page doesn't work as expected. In order to look for the root cause, please follow the steps below and provide us with more information to troubleshoot your issue.

  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. Does the problem persist?
  2. If the problem is not fixed, try clearing Firefox cache. Does it help?
  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). Does it help?
  4. If it also does not help, try running Firefox in Troubleshoot Mode. Does the problem persist?

Looking forward to your update!
