Hi V1cky,

One of the reasons you're getting this error message could be that the time and date setting on your system are incorrect - would you check to see if they are in Windows Settings, please  ?

If that's not the cause, then would you take a look at this article :

You can try to enable all third-party cookies temporarily to see if that has effect.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

• make sure your extensions and filters are updated to the latest version

You see the shield icon at the left end of the location/address bar in case content is blocked by Tracking Protection.

• click the shield icon for more detail and possibly disable the protection
• check the Web Console for more detail about what content is blocked by Tracking Protection
• "3-bar" menu button or Tools -> Web Developer

@Murphy Windows time settings is ok. Any suggestion on the link you said did not work Thanks for the answer

@cor-el I have my tracking protection only in private window. I switch it to never But nothing happened Add-ons are up to date. Thanks for the answer

@ V1cky,

Could you possibly give us a link to the TV website in question  ?

You're absolutely sure that Windows time setting is correct - like e.g. not PM when it should be AM  ?

Did you try to enable third-party cookies?

To see all History and Cookie settings, choose:

• Options/Preferences -> Privacy & Security -> Firefox will: "Use custom settings for history"
• https://support.mozilla.org/en-US/kb/Options+window+-+Privacy+panel

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

Thank you for that link - I works just fine for me, but that's not helping you any.

I must admit that I'm baffled : you have tried everything that's been suggested and nothing works - I'm plumb out of ideas (sorry .... ).
