Preferences are set custom - clear cache/copokies on exit. Doesn;t function properly and cookies are still there when started again. 53.02 worked perfectly.

Chosen solution

Can you clear these items manually without any problems?

Note that Firefox can save some session data in sessionstore.js when you close Firefox with tabs open. --- Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window

Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.

  • "3-bar" menu button -> Exit (Power button)
  • Linux: File -> Quit
  • Mac: Firefox -> Quit Firefox
  • Windows: File -> Exit
