Safari shows only one post in Facebook

Hi,

Since around one month now, Safari shows only one post in Facebook. I do not have dashlane extension. In fact, I have only one extension, the adblock.

What I see is that the rest of the posts are loaded for a glance but they are removed immediately and only the first one remains. My account is OK from Google Chrome.

The same happens in another user of the same iMac, again with Safari. Safari does not work, Google Chrome works.

I have cleared website data. I have cleared caches. Nothing works. Any solution?
