Seeking a program or Firefox extension that blocks flash cookies

[Ace]

You can open Flash's settings and tell it to never allow sites to store data on your computer, or be prompted to allow them to store it, but for me this setting reverts to the default (allowing all sites to save data) immediately upon browser exit, presumably because it stores the data via a cookie or some other thing that's being purged when I shut my browser. Nothing in my current setup has sufficiently granular controls to do this (I think?). The closest I've found is BetterPrivacy, which has the ability to whitelist sites, but rather than blocking flash cookies it allows you to set a timer to purge them on a user defined schedule (every 10 minutes, 30 seconds, etc.). Is there an extension or program out there that will block all non-whitelisted sites from placing flash cookies?

try -
Image and Flash Blocker
Flashblock :: Add-ons for Firefox
Flash Control :: Add-ons for Firefox

None of those seem to block flash cookie placement

Sorry to say, there are no any better addons left for firefox i guess.at least i tried flashblock with better privacy & it blocks almost flash videos/advertisement automatically to save bandwidth & placing flash cookies on my system. If u click on flash videos, advertisements, online games manually then it will store flash cookies. If u r paranoid then set " block all sites from storing information " in flash player settings which is currently working in my system without any hassel. try to disable every addons & change the flash settings again. I think it's the only way, or use portable browser in private mode in flash drive, & clean browser cache/cookies with ccleaner after closing ur browser. In flash world u can't stop flash from reaching ur computer 100%.

Better privacy is the closest. Maybe try setting the time to 0 or 1 second
