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?
