Flash cookies, Adobe’s so called “shared objects”, store information about your visits which are not properly restricted by your browser’s privacy settings nor in private browsing. Google, Skype, Amazon, Flickr, Joost and even The New York Times all have written Flash cookies to my browser that I could not control from my browser’s own preferences. Weaknesses in earlier Flash cookies enables one website to read other website’s cookies. Hmmm, will my penchant for certain spicy food recipes at one website show up in my Amazon’s book recommendations? Possible, but not likely. Only because Amazon, I think, would not do such an evil thing, right?

Manage your Flash cookies at any time here or, control click on a Flash movie when one is being displayed and select “Settings” (Mac). It’s a web page at Macromedia’s website which accesses your Flash Player settings so you can manage them. The image on that web page is your actual Adobe Flash Player Settings Manager — interact with it.

What’s so creepy about the various Flash Player settings is the camera and microphone access. Which sleazy website might have snapped a picture of your unshaven face, in your penguin print jammies as you played an online Flash game or watched a Flash video presentation?

Here are the other tabulated settings you can manage …
