Re: Torbutton Documentation - Adversary Capabilities.

I would look at "about:plugins" and see what Firefox has loaded. Torbutton does a good job at stopping third party plugins, but if you specifically allow Flash and do not clear the cookie from Flash, you may have a problem.
Other than that, you have the right idea.
I don't know exactly where it is on their site, but the Flash website describes how to delete them. As was suggested in another answer, using Firefox with the addon 'BetterPrivacy' is the best way to go.
Sadly, there is no software currently available anywhere that will remove Flash Cookies. All any of these programs do at best is temporarily remove some of them. The developers of these flash cookies are very aware of all these deletion attempts, so they add a variety of codes that prevent any deletions. The programs move the cookies to several different files in the system which allows them to continuously repopulate immediately after they are removed from any of the locations. No developer of any of these deletion programs has come up with a way to find and delete these flash cookies all at the same time, and prevent them from being added again. One of the biggest culprits is Adobe with their Flash Player, along with other programs, which has always been a security risk and still is. Adobe is in cooperation with the advertising community and develops their products in cooperation with them, with features that allow advertisers to use the Adobe Flash Player to infiltrate any computer using the Flash Player and place flash cookies on any user’s system. The Adobe Flash Player therefore as a result is very vulnerable to hackers, etc. If advertisers can use it to place Flash Cookies on a user’s system, a hacker can easily place a Trojan program or any other type program on anyone’s system. The Adobe Flash Player is especially vulnerable when a user allows the Flash Player to take control of their webcam and microphone hardware. The Adobe Flash Player is FREE to the user. Adobe does not charge the user for the Flash Player; they get paid by the advertisers. That’s how Adobe makes their money for Flash Player. Even more insidious is they way Adobe provides the settings feature for Flash Player; it’s controlled by them on their site, and apparently the advertisers as well. Users who attempt to change the settings only think they are being changed. This is another way in which Adobe and the advertisers trick users. The settings will return to the original state the advertisers have programmed them for to ensure that they can continue to place Flash Cookies on a user’s system. A user can verify this by selecting the settings option, which accesses the Adobe site, then change the settings to their preferences, and then close the program. Then restart the program and access the settings again. The user will discover that the settings have been changed back to the way Adobe and the advertisers set them. There are numerous reliable sources that support these facts. Anyone who disputes them is likely a plant or part of the Adobe and advertiser ilk. Here are a couple of sites where you can verify these facts (there are many more, just do your research): http://www.wired.com/epicenter/2009/08/you-deleted-your-cookies-think-again/ http://lifehacker.com/5334984/web-sites-using-flash-instead-of-browser-cooki... It's sad that this is how unscrupulous these businesses are, but that's what greedy companies do everywhere. Ethics are not a part of any business like these. -- Facundo Andrés Bianco (Vando.)
