Hello, are you able to enter those websites from other browsers?

Hi Konstantina, I was able to enter those websites using Microsoft Edge. I don't use Google Chrome any more because it was too unstable on my desktop computer.

Hello, thank you for the extra info. Here is a list of things you can do so we can define the root cause. # 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? #* If nothing from the above helps, that's a compatibility issue. Please report it on [https://webcompat.com/issues/new Webcompat], so that our team there may be able to look into it. We'd also appreciate posting a link to your report here. <!-- Some additional troubleshooting steps * What kind of ETP setting you have? To find out, go to ''about:preferences#privacy'' and let us know if you set it to Standard/Strict/Custom. '''Check if the issue is caused by Total Cookie Protection (TCP)''' <i>'''WARNING from the moderator team:''' ''Changing Firefox pref from the about:config page can sometimes break Firefox or cause strange behavior. You should only do this if you know what you're doing. Please read [[Firefox advanced customization and configuration options]] to learn more. '' </i> * Go to about:config and check if the pref “''network.cookie.cookieBehavior''” is set at 5, which means that TCP is enabled together with ETP. If the pref value is not 5, then the issue is not TCP-related. * Set the pref “''network.cookie.cookieBehavior''” to 4 and check if the issue still exists. If the issue disappears, then it is a TCP breakage. In that case, you can file a report through [https://mzl.la/anti-tracking-breakage Bugzilla] or reach out the [https://matrix.to/#/#anti-tracking:mozilla.org #anti-tracking] team on Matrix. -->

Hi Konstantina, Thank you for the quick reply and the four things to try. I've tried all four things and the problem still persists. I will report to Webcompat and link to this report. Once again thank you for the quick reply and things to try to resolve the problem. Lovell
