This behavior is observed only if "Restore previous session" is not enabled to occur automatically at startup. 1) Ubuntu 20.04.2 LTS 2) 91.0+build2-0ubuntu0.20.04.1 3) "Restore previous session" should not change window settings and appearance 4) "Restore previous session" drastically changes window settings and appearance in a very unpleasant way Steps to reproduce: 1) Don't have "Restore previous session" enabled in Settings > General > Startup 2) Browse some sites 3) Close the window and confirm your desire to close it 4) Reopen Firefox 5) Go to History and select "Restore previous session" 6) The window will break apart as a result Screenshot below.
