Not erasing cookies/history

more options

Okay, hi- first time here. I have, as far as I know, all my preferences set correctly- clear history and cookies upon shutdown, etc yet EVERY time I reopen Firefox it's attempting to resume my last session which seems to me to be the opposite of how I have it configured so I was wondering what I also need to do to eliminate this privacy concern. Thanks in advance~

The session restore is an option. See; https://support.mozilla.org/en-US/kb/how-to-set-the-home-page

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)
  • Windows: File -> Exit
  • Mac: Firefox -> Quit Firefox
  • Linux: File -> Quit

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

  • browser.sessionstore.resume_session_once

You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.

  • rename/remove sessionstore.jsonlz4 and sessionstore.js

You may also have to rename the sessionstore-backups folder.

When sessionstore.jsonlz4 is deleted you lose pinned-tabs and open tabs and you will have to recreate them, so if necessary make a note or bookmark them. sessionstore.jsonlz4 is only present in the Firefox profile folder when Firefox is closed.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).

I also cannot remove all cookies on shutdown. I wish to ignore white list, or any other limitation, and automatically remove ALL cookies so that, on my next start-up, there is NO memory space taken up with cookies.

If necessary, I will be pleased to have all whitelist contents deleted on each shut-down.

I do want to keep browse history and have past windows open automatically. This question is only about cookies.

I have set up the HISTORY section of Setup to delete all cookies, but no joy.

I am running Firefox 97.0(64-bit) on Ubuntu-Mate 20.04.

Please tell me how I can do this automatically.
