    If I set up multiple firefox profile, and 1 profile have a flash cookie, will it affect the other profile?

    If I use private proxy with the second profile, will it leaks my real IP?

    it is better to use portable versions of Firefox each setup with a diferent IP, than diferent profiles.
    I use 2 plugins CookieKiller and BetterPrivacy (for flash cookies).
    And if you are really skeptical use a free VPN like HotspotShield for example.

    Can not post links so google it around.

    Hope this will help others.

    I use private proxies for this, but I am sure if they leak IP.

    Is there really a different between multiples firefox profile and multiple portable version of firefox?

    The new profile will be installed in different folder.

    It depends if your private proxies are anonymous proxies or transparent proxies:

    Transparent Proxies
    They do not hide information about your IP address:REMOTE_ADDR = proxy IP


    Anonymous Proxies
    All proxy servers, that hide a client's IP address in any way are called anonymous proxies.

    And you need to use a plugin to delete all your cookies.

    To answer your question, as far as I'm aware yes the flash cookie of 1 profile will affect the other profiles if you are running them simultaneously. This kind of defeats the purpose of running multiple profiles at the same time. Portable versions of Firefox are not required as each profile can be setup in a unique way, all you'll need is a plugin like BetterPrivacy to clear your flash cookies. Unfortunately running multiple profiles at the same time may leak information due to flash cookies, even if you use BetterPrivacy. You could probably keep all of your profiles opened at the same time, but you'd have to keep them on a blank page and whenever you'd switch between them, you would need to clear the flash cookies.

    BetterPrivacy is really strange.

    I install them on one profile then close firefox.

    Then I use ccleaner to clear cookies.

    There are still cookies left unclear.

    BetterPrivacy is for flash cookies, not your typical cookies. With multiple profiles you don't really need to worry about the typical txt cookies.

    If you're running on Windows, they're usually stored in this directory depending on the OS you are using: "C:\Users\~USERNAME~\AppData\Roaming\Macromedia".

    You can also take a look at CookieSwap which could be handy:
    Code:
    https://addons.mozilla.org/en-US/firefox/addon/cookieswap/

    Though if your main purpose is to be unique from the other profiles, your best bet is to stick to multiple profiles as you can customize each profile in a unique way.

    To test the uniqueness of the profile use this site:
    Code:
    https://panopticlick.eff.org/
    The more you customize your profile, i.e different plugins, etc, the more unique each one will be.
