after firefox updated from v15.0.1 to v16.0.1 on Friday (10/19/12), collusion v0.22 shows 3rd party cookies being shared, and a lot of them. I have firefox in "always use private browsing mode", with cookies not allowed, in addition there are no entries in "exception" or in "show cookies". The check boxes for cookies and 3rd party cookies are NOT checked. This behavior never happened before the update! I re-installed v15.0.1, but it is still happening. Rana full sys scan with the latest Norton Security, which found nothing. Tried a few others too, so I'm semi-certain that my system is not infected. System: Acer 5251-1245 with windows 7 (current patch levels up to date). What changed with v16.0.1 update? Did Collusion change? why are 3rd party cookies being shared, and how is it doing it? Is there a way to check to see if other browsers have the same issues? e.g. chrome, explorer (yuck!), safari, etc.... I've really liked Firefox, but I am afraid to use it, especially to shop online or any financial stuff (banks, credit card payments, etc.). Maybe I was better off in blissful ignorance before installing collusion earlier this year, but I only ever saw the 3rd party cookie sharing when I had "cookies" turned on without turning on "Accept third-party cookies". Again, what changed?

Which other extensions do you have?

Sounds that you may have an extension installed like Do Not Track that includes permanent opt-out cookies.

only add-on extensions are "Collusion v0.22" and "Adblock Plus Pop-up Addon v0.4". The issue never happened until Friday 10/19/12 after the Firefox v16.0.1 update, and was noticed by me on Saturday while using the Firefox to check my work schedule (which sets only its cookie and does not share, but it did and got me worried).

Still wondering if Collusion updated too, and now I'm seeing new behavior.

I do not want to share cookies, which is why I turn them off, and never turn on "share third party cookies".

Do I need to stop using Firefox? :(
