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

You can hide the "˅" in the tab bar by changing browser.tabs.tabmanager.enabled to false in about:config.

Extensions need permission to run in private windows when the browser is in private browsing mode (aka "Never Remember History"), otherwise they won't appear in the Extensions panel.
