Two cookies cannot be deleted. When I delete them, close the cookie window and reopen, they reappear. How do I get rid of them?

I only keep allow a few permanent cookies on Firefox, and routinely clear most at the end of a browsing session. Recently two cookies cannot be deleted. I delete them in the cookie window, close and immediately reopen, and lo and behold, there they are again. Do I have to delete all to achieve this? Is the cookies.sqlite file corrupt?

What cookies are that?

Is that from tabs that are open?

Did you try to remove the cookies.sqlite file temporarily to check for such an issue?


There are other things that need your attention.

Your System Details List shows multiple Flash plugins.

  • Shockwave Flash 15.0 r0
  • Shockwave Flash 14.0 r0
  • Shockwave Flash 12.0 r0

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.
