Flash Cookies and DOM storage

[43unite]

In Firefox dom.storage.enabled can be set to false. This disables dom storage.

As Graycode indicated, linking items such as ~/.macromedia/Flash_Player/#SharedObjects and ~/.macromedia/Flash_Player/macromedia.com/support/flashplayer/sys/#* to /dev/null prevents saving/storing LSOs while preserving the user's global settings.sol. Flash functions normally.

http://en.wikipedia.org/wiki/Data_sink
In Unix-like operating systems, /dev/null or the null device is a special file that discards all data written to it (but reports that the write operation succeeded), and provides no data to any process that reads from it (yielding EOF immediately).
http://en.wikipedia.org/wiki/End-of-file
End-of-File, commonly abbreviated EOF, is a condition where no more data can be read from a data source.
