Hello Mr Theo Loyla,

Would you try this please :

Reload the page : Hold down the Shift key and left-click the Reload button or press 'Ctrl + F5' or press 'Ctrl + Shift + R'

Next thing to try :
Clear the Firefox cache :
https://support.mozilla.org/en-US/kb/how-clear-firefox-cache

"Remove the cookies" from websites that cause problems :
https://support.mozilla.org/en-US/kb/delete-cookies-remove-info-websites-stored (scroll down to : "Delete cookies for a single site")


If you use extensions like Adblock Plus, NoScript, Flash Block, Ghostery, then always make sure such extensions do not block (wanted) content.

You could also check your settings here :

https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop

(if you see the shield icon next to the padlock (on that site), you could click on it and turn Enhanced Tracking Protection off)


If none of the above do the trick, then let's try Firefox in Safe Mode :

If Firefox is not running : Hold down the Shift key when starting Firefox.

If Firefox is running : 3-bar menu => ' ? ' (at the bottom of the dropdown) => 'Restart with Add-ons disabled'. Then OK the restart. A small dialog should appear. Click 'Start in Safe Mode' ( not 'Refresh' !)

See : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

And : https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems

Does any of the above work ?

Remove History For One Site

Open the History Manager <Control><Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any settings.

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required) ?

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

Firefox shows a blueish highlighted shield icon at the left end of the location/address bar in case Tracking Protection is blocking content. You can click shield icon for more detail and possibly disable the protection. You can check in the Web Console what content is blocked.


You can remove all data stored in Firefox for 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 for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for 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 for that website will be saved once again.

If that site doesn't like Firefox; there's nothing we can do .....

However, when I went searching for a solution to your problem, I came across a Google thread, where people had the same problem using Chrome ..... (but it was a few years go, though).

I'm thinking that many problems these days are caused by the corona crisis we're dealing with.
