BetterPrivacy is a Firefox extension that protects against not deletable long term cookies, a new generation of Flash cookies or Super Cookie, which silently conquered the internet. This addon was made to make users aware of those hidden, never expiring objects and remove those objects on every browser exit.

Flash cookies (Local Shared Objects, LSO) are pieces of information placed on your computer by a Flash plugin, placed in central system folders and so protected from deletion. Flash is a separate application running on your system, there is no way to prevent it from storing those LSO’s on your disk. They are frequently used like standard browser cookies. Although their thread potential is much higher as of conventional cookies, only few users began to take notice of them. It is of frequent occurrence that -after a time- hundreds of those Flash-cookies reside in special folders. And they won’t be deleted – never.

With BetterPrivacy it is possible to review, protect or delete new Flash-cookies individually. Users who wish to to manage all cookies manually can disable the automatic functions. BetterPrivacy also protects against ‘DOM Storage’ long term tracking, a browser feature which has been granted by the major browser manufactures.

How does BetterPrivacy work?
BetterPrivacy finds the folder where your Flash plugin stores the LSO’s. Thus the first start of Firefox could be delayed for some seconds. Then BetterPrivacy does absolutely nothing until you close Firefox. At that time the addon will look at the LSO folder and if there are cookies existing it will show a popup. BetterPrivacy asks if you would like to delete the LSO’s at that time. You might decide to review every single LSO later at the next session. Otherwise you can choose to delete or even auto-delete on every Firefox exit.
