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.

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.
You can do a Search for them by searching for *.sol and you will find a lot of them.
You can VIEW the content of some of the cookies (some are encrypted) with your Notepad or similar program.
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.
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.
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.
