They function a lot like cookies and can be used to store session information or save a game progress. The real problem that many users have with them is that they do not know that they exist because they are not stored in the same directory as the normal browser cookies.

Adobe is providing a website with options to change Flash Cookie behavior. Users can change the storage space – default 100K – or deny access to Flash Cookies to websites that they have already visited.

It’s not a practical solution though. Objection on the other hand is a Firefox add-on that is giving access to the Flash Cookies right in the browser. It is not possible to change settings with the add-on but it provides an easy way to delete selected (or all) Flash Cookies.

The add-on provides an automatic search to find the location of the Local Shared Objects Folder on the system. It was not able to detect mine and I had to manually add it by browsing to the correct location. According to Wikipedia Flash Cookies are located in..

  • Windows: LSO files are stored typically with a “.SOL” extension, within each user’s Application Data directory, under Macromedia\Flash Player\#SharedObjects.
  • Mac OS X: For Web sites, ~/Library/Preferences/Macromedia/Flash Player. For AIR Applications, ~/Library/Preferences/[package name (ID) of your app].
  • GNU-Linux: ~/.macromedia

All Flash Cookies stored on the system are displayed once the folder has been correctly identified. A click on a Flash Cookie displays its contents. The user has the option to delete selected Flash Cookies only or all of them in one go.
