Manage Flash Cookies with this widget I created: LSOManager

Because of Opera's File I/O security, you'll need to explicitly allow access to the location of these files. On first run, LSOManager will enter setup:



On Ubuntu this location is

~/.macromedia

On Windows this location might look like

C:\Documents and Settings\your username\Application Data\Macromedia

After mounting the proper location and restarting LSOManager, you'll be presented with a screen similar to this:



Here you can search, sort, delete and mark certain flash cookies/settings protected from deletion.

You can try it out here: LSOManager.wgt
