I tried to delete all cookies using Tools->Options->Show Cookies->Remove All Cookies. But all deleted cookies keep coming back after few seconds. I suspect there is a malware doing this. I run into this problem in the past. It was caused by an AddOn called something like * xg.dll by Relevant Knowledge. When this add-on was removed the problem went away. But now, it comes back again.

Chosen solution

That are opt-out cookies added by the TACO extension.
You can only them if you disable or uninstall TACO.

Targeted Advertising Cookie Opt-Out (TACO): https://addons.mozilla.org/firefox/addon/11073

TACO with Abine prevents over 100 different online advertising networks (including Google, Microsoft and Yahoo) from displaying highly targeted advertisements using the detailed information on your web surfing habits. TACO disables most behavioral advertising by setting 100+ permanent, generic, non personally identifiable "opt-out" cookies directly into the browser.

Unlike other opt-out solutions, this tool will make the opt out cookies completely persistent. That is, clearing the browser's cookies will delete all other installed cookies, except these.

Thanks. I did found it yesterday. I disabled TACO a month ago because I can't logon to my account on COMCAST, but it seem it got activated again inadvertently.
