Oh, it requires an account... I guess I won't be able to test then, but here are some standard troubleshooting steps that may help: # Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield [[Image:Fx89ShieldIcon]] icon at the left of the address bar. #* If ETP is enabled, try disabling it. # If the problem is not fixed, try [[How to clear the Firefox cache | clearing Firefox cache]]. # If it does not help, also try [[Clear cookies and site data in Firefox | clearing cookies and data]] for the website you experience troubles with (''warning: you will be logged out on this website''). # If it also does not help, try [[Diagnose Firefox issues using Troubleshoot Mode | running Firefox in Troubleshoot Mode]]. If the problem doesn't persist, please follow the steps from [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems | this article]] to troubleshoot further.
