Five months after a string of lawsuits unveiled Flash's complicity in restoring zombie cookies, Adobe Systems has finally promised to do something about it. The operative word is "promised."
At its heart the trick's pretty simple. A website that wanted to maintain tenacious cookies only needed one extra step. In addition to placing a cookie on the user's PC, they also used the good services of Adobe Flash to keep a backup copy of the cookie. That way, if the user deleted a particular site's cookie, the site could rummage around in Flash's storage to see if there was a backup.
Third, Adobe promises that some day you'll be able to control Flash cookies directly from within Windows, Mac OS, and Linux. Called the Flash Player Settings Manager, the new utility's supposed to integrate with the Windows Control Panel sometime in the first half of this year. (Call me skeptical, but it could happen.) In the interim, Flash says it's improved the weird online program that it's always pushed for adjusting Flash cookie settings. I don't see any difference from the old version: It still sports a bizarre, convoluted interface that doesn't look like it's doing anything. If you want to see what Flash cookies are stored on your system, go to that weird online program and click the second icon from the right -- bet you'll be amazed.
I agree with the writer, that ridiculous Flash global settings thing is a convoluted MESS, I never could quite get the hang of it. I use the Everything search engine to clear out unwanted Flash "Zombie" cookies once a week or so.
