BetterPrivacy

BetterPrivacy is a Firefox add-on that is able to delete a special kind of cookies: Local Shared Objects in short LSO's (usually known as Flash-cookies) are placed on your computer by a Flash plug-in. LSOs are harmfull because

• they never expire
• they by default offer a storage of 100 KB (ordinary cookies: 4 KB)
• browsers are not fully aware of LSOs, LSO's often cannot be displayed or managed by browsers
• via Flash they can access and store highly specific personal and technical information (system, user name,…)
• of the ability to send the stored information to the appropriate server, without user's permission
• Flash applications do not need to be visible to the user
• there is no easy way to tell which LSO sites are tracking you
• shared folders allow cross-browser tracking, all browsers use the same LSO folder
• the company doesn't provide a user-friendly way to manage LSO's, in fact it's incredible cumbersome
• many domains and tracking companies make extensive use of LSOs
• LSOs are used to re-create data of deleted traditional cookies
