Hi there, Could you please share some examples of such URLs? Also, here are some standard steps that may help you: # 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. Does the problem persist? # If the problem is not fixed, try [[How to clear the Firefox cache | clearing Firefox cache]]. Does it help? # 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''). Does it help? # If it also does not help, try [[Diagnose Firefox issues using Troubleshoot Mode | running Firefox in Troubleshoot Mode]]. Does the problem persist? Looking forward to your update!
