The sidebar would normally stay closed if you close is and close and restart Firefox. Isn't that happening to you ?

Can you attach a screenshot?

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

Also, Firefox has a "semi-retired" feature to reduce the heights of the toolbars. See: Compact mode workaround in Firefox.
