No Saving or Restoring of Windows and Tabs, Even With All Add-ons Disabled, Unless I Restart in Safe Mode

I have posed this question under "Fix slowness, crashing, error messages and other problems," and under "Other," and have not gotten a single response. So I am trying it again here.

This is a major glitch, and I am surprised that no one else is dealing with it too! 

Is there anyone who works for Mozilla who monitors these forums who can help?
=========

After upgrading to FF 84, my previous sessions are no longer saved and restored unless I restart in Safe Mode.

- I have Restore previous session checked in Preferences.

- I have opened new windows and tabs and one by one disabled and restored every add-on that I have had enabled and quit and restarted each time, until every single add-on has been disabled, and still the previous sessions are not saved and restored.

- I have looked in the sessionstore-backups folder with each restart, and there is never any file for the previous sessions in it.

- I have cleared all my cache before quitting and restarting.

- Again, even when there are absolutely no add-ons enabled, the previous session is not saved and not restored.

- Again, only when I restart in Safe Mode is the previous session saved and restored.

What is the solution?

You may have corrupt sessionstore [v56] sessionstore.jsonlz4 file(s). Delete all sessionstore* files and the sessionstore-backups folder.

Type about:support<enter> in the address bar.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Locate the above file. Then rename or delete it. Restart Firefox.


Don't delete the files if you need to rescue any data from them, just move them out of the profile folder to some location where Firefox doesn't look for them. You can try to read out their contents using this tool: https://www.jeffersonscher.com/res/scrounger.html

Thank you.

I did all as you instructed, but when I restart FF, again, the previous session still doesn't come up, and doesn't show anywhere to let me restore it, and Recently Closed Tabs and Recently Closed Windows are grey, although these files do indeed have the previous sessions in them.

So how do I get the browser to work properly and connect with and open its Previous Sessions?

Should I completely delete it and reinstall?

Use these links to create a new profile. Use this new profile as is. Is the problem still there?

Your issue could be related to a corrupted xulstore.json file. See, for example, this article on this site: [https://support.mozilla.org/en-US/kb/.../changes-toolbars-and-window-sizes-are-not-saved]

Make sure you do not run Firefox in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).

  • Options/Preferences -> Privacy & Security
    Firefox will: "Use custom settings for history"
  • remove checkmark: [ ] "Always use Private Browsing mode"

In case you use "Clear history when Firefox closes" or otherwise clear history.

  • do not clear the Browsing History
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
  • clearing "Cookies" will remove all cookies including cookies with an allow exception you may want to keep
