By default, clearing cache and cookies in Mozilla Firefox doesn’t remove Flash cookies stored due to use of Flash player when browsing websites.
In Linux Mint / Ubuntu, these cookies are stored in the home directory within a hidden directory, the full path for which is /home/username/.macromedia/Flash_Player/#SharedObjects.

echo "Deleting Flash cookies from current user's home directory.."
sudo rm -rf $HOME/.macromedia/Flash_Player/#SharedObjects/*/*
echo "All done"

By the way another method to delete Flash cookies and objects is through this awesome Firefox plug-in in case above post is boring :).
