Only get top menu when logging in into Facebook

[Veryfakebook]

Since about two weeks Facebook pages only show the top menu bar if Facebook Container is turned ON.. I can see that I have messages but can't open them. As soon as I turn Facebook Container OFF everything works normally.

• Facebook Container Version: 2.0.3
  • Operating System + Version: OSX El Capitan 10.11.6
  • Firefox Version: 71.0

Actual behavior

Facebook page opens with only top bar visible if Facebook Container is ON Facebook page opens normally if Facebook Container is OFF

Expected behavior

Facebook opens normally if Facebook Container is ON

Steps to reproduce

1. Type facebook.com in address bar and hit return
2. Turn Facebook Container either ON or OFF
3. See if only top bar shows or complete page

Notes

Is this still reproducible on the latest version of the add-on (2.1.1) and Firefox (77.0.1)?
