I've set Firefox to remove cookies when I close the program. But when I close Firefox and run CCleaner, CCleaner reports removing many Firefox cookies. So Why does the Firefox feature "Keep (cookies) until I close Firefox" not work?

Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank you.

If you have installed an extension like Beef Taco or Do Not Track Plus that maintains a set of OPT-OUT cookies then you can't remove some cookies permanently.

In that case you need to uninstall the extension to remove those opt-out cookies.
