facebook.com on safari "empty"

[redAPPLE]

hi.

i have high sierra and i just noticed this a week ago.

i opened a new tab and typed in "facebook.com".

and the website is completely empty (see atttachment).

unfortunately i got "a lot" of open tabs, that i need at the moment. i am scared, resetting safari would remove these tabs.

any idea how to fix this? i am not sure if this is a facebook issue (with high sierra), or is this happening with other websites too? do you know, if resetting safari would close all the tabs?

thanks.

How do I update my root certificates on an older version of Mac OS (e.g. El Capitan)?

I have difficulty reaching various secure web sites. They give me a certificate expired error. They work on Firefox but not Safari or Chrome. They also work on newer versions of macOS (e.g. Catalin...
