Facebook requiring login for all of their pages from desktop

This is a follow-up to this locked-up thread from 2021: https://trisquel.info/es/forum/abrowser-breaking-facebook

Summary of the thread: Do not use Facebook. If you do because of not wanting to miss some information, do it in the most protected way: no app, no login. But then, you will find that sometimes Facebook refuses to show public pages and require login. It looks like a whimsical thing, happening some days only.

It is happening again since yesterday. But not only on Abrowser, or in Trisquel - it is happening on every desktop computer. I am seeing it on Trisquel: on Abrowser, Icecat and GNOME Web browser. I am seeing it on Edge on Windows 10. And I am seeing it too on my Android smartphone when I request a desktop view.

I think kerdadit was right on the original thread, this has nothing to do with my devices - Facebook just serves pages differently.

I followed chaosmonk's advice - to replace the part of the address before ".facebook" with an "m". Pages are still served right for mobile devices, even if they served are a bit differently. Good enough.

Example: Festival Intercéltico do Morrazo
