Did you check the Inspector and Web Console for reported issues ?

I notice you have Adblock Plus installed.

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.

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

Firefox shows an highlighted shield icon at the left end of the location/address bar in case Tracking Protection is blocking content.

• click the shield icon for more details and possibly disable the protection

You can check in the Web Console what content is blocked.

I also see you still have the "hotfix-update-xpi-intermediate" extension installed to fix an issue from May 2019 with an expired intermediate certificate. You can uninstall/remove this extension as this fix is builtin in Firefox 66.0.3 and later.

Can you please say how to delete it. I didn't find any extension with that name.(

Turning off AdBlock and trecking protection didn't help.

Does this only not work on these specific websites ?

Did you check this with the Inspector and the Web Console?

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

I understood that this is an internal problem of the website. Anyway thanks for your help.)
