Everyone heard of http cookies. Everyone knows that cookies can be a problem when it comes to privacy. But everyone is not aware that flash player have their own cookies mechanism.

If you go on this page you’ll see a little flash application provided by Adobe to mange your flash settings and the cookies stored by flash.

Here is how the application look like.

Yeah, but WHY does Adobe have to muck around on our own hard drives, rather than building this Block-Cookies utility into their product? Very suspicious.

Not only that, but it appears cookies STILL get placed on our computers even after going thru the hassle & privacy invasion of making setting-changes on Adobe's site.

P.S. We only learn about Flash-cookies the HARD WAY or by ACCIDENT. WHY is that?? Adobe is extremely secretive about the fact that it has COOKIES BUILT INTO Flash Player! Not fair, not nice.

  1. Even after you go (repeatedly) to the adobe/macromedia website and think you have set FlashPlayer to stop hiding these nasty secret cookies, they still appear on your hard drive.

  2. You can do a Search for them by searching for *.sol and you will find a lot of them.

  3. You can VIEW the content of some of the cookies (some are encrypted) with your Notepad or similar program.

  4. MAXA COOKIE MANAGER (Germany) will find these secret cookies (and will let you see their content), but if you want to delete them, you need to buy the Paid Version of MAXA.

  5. These cookies are NOT HARMLESS! They contain highly specific, personal info about your computer and your viewing habits. Some of them even include your computer's name and directory paths. This is way too invasive and should not be allowed--especially when done secretly behind our backs like this, by Adobe/Macromedia.

  6. If you feel these secret Adobe/Macromedia spy cookies are a violation of your privacy and personal boundaries, COMPLAIN LOUDLY to adobe & DEMAND that they provide a PATCH that allows end-users to set the parameters (ON OUR OWN HARD DRIVES without interference from Adobe!) for whether these cookies appear on our machines...

GOOD LUCK!

PS CCleaner claims that it will detect and remove these FlashPlayer cookies, but we haven't yet found which version will do that--and for which browsers.

The cookies are stored here: %APPDATA%MacromediaFlash Playermacromedia.comsupportflashplayersys\

There is a directory for each website you have visited, and even if you delete all the cookies using Adobe's flash-management tool, the directories remain showing all the "www.website.ext" places you've been.

There is a settings.sol file in this directory which contains all the options you've set using the tool, so you can't just nuke the "sys" directory and recreate it without backing up this file first and restoring it after you're done.

Batch file to nuke these cookies: :: KillFlashCookies.cmd

:: backup the settings file if exist "%temp%settings.sol" del "%temp%settings.sol" copy "%APPDATA%MacromediaFlash Playermacromedia.comsupportflashplayersyssettings.sol" "%temp%" :: nuke any existing cookies and subdirectories rd /q/s "%APPDATA%MacromediaFlash Playermacromedia.comsupportflashplayersys" md "%APPDATA%MacromediaFlash Playermacromedia.comsupportflashplayersys" copy "%temp%settings.sol" "%APPDATA%MacromediaFlash Playermacromedia.comsupportflashplayersys" :: del settings.sol from %TEMP% del "%temp%settings.sol"

I used this: https://addons.mozilla.org/en-US/firefox/addon/6623 after reading the suggestions on this site. I found all kinds of *.sol files and after installing this addon, they were all gone. It seems to work well for Firefox browsers (2.0.0.16).

thanks for giving the link to that firefox plugin. the "better privacy" firefox plugin + the maxa cookie manager lite tool were able to clean hundreds of hidden cookies off my machine.

Consider using [HTML_REMOVED]History Killer Pro[HTML_REMOVED]. "Adobe cookies" is the last menu item in the program.

BleachBit is a free/open source tool to easily delete Flash cookies and many similar privacy concerns http://bleachbit-project.appspot.com/

Using Win 7, I devised this and I can still get to both my banks and eBay. I don't know yet if other sites will still run.


Set permissions for Macromedia > Shared Objects > {random name} to Deny for SYSTEM & Administrator.

Repeat for Macromedia > macromedia > support > flashplayer > sys

Select All > Shift-Delete > Yes for both

Wake up and smell the burnt toast.

Marketing Depts and Marketeers are evil - they exploit every loophole they can find, steal any data possible, and claim they "only want to enhance the users experience"

from http://epic.org/privacy/cookies/flash.html

"Persistent Identification Element ("PIE")

United Virtualities (UV), an online marketing firm, has introduced a tracking platform that takes advantage of the relative obscurity of Flash cookies. In a press release this March, UV announced PIE, a backup ID system for cookies. Mookie Tenembaum, founder of United Virtualities, explained the reasoning behind the product, "All advertisers, websites and networks use cookies for targeted advertising, but cookies are under attack. According to current research they are being erased by 40% of users creating serious problems."

UV's press release also claims that the PIE system can restore deleted web cookies. Although there is little official information on the implementation of the PIE system, it is not likely that the cookie is actually restored. Instead, it appears that the Flash cookie acts as a redundancy. That is, the PIE system uses Flash cookies as a backup. A site interested in tracking a user would set a normal cookie and a Flash cookie. If the user erased the normal cookie, the PIE-enabled site could use the redundant Flash cookie to track the user.

To justify this tracking mechanism, UV's Tenembaum said, "The user is not proficient enough in technology to know if the cookie is good or bad, or how it works."

This practice is highly deceptive. By deleting cookies, consumers are clearly rejecting attempts to track them. Using an obscure technology to subvert these wishes is a practice that should be stopped. Cookies have many beneficial purposes and can make the end user's web experience better. Websites should be honest and up front about how they use cookies, and they should respect the decisions of those users who do not want to be tracked via cookies. "

Funny thing is about about Adobes privacy manager. You just can't block cookies. You have to manually deny cookies. So sites bombard you with 100 cookies and have to click deny each time. Not to mention; there is something like a 2 second pause between each time you hit deny cookie.

Hell, it can take 5 minutes to deny flash cookies while searching a Sunday ad paper.

So, why can't Adobe just allow people to block cookies permanently? Just sounds funny.
