There is a nice writeup on these cookies and simple (non-firefox/global) protection from such cookies at:
http://www.linuxplanet.com/linuxplanet/tutorials/6709/1/

No need to go extreme and lose most functionality by going 10000% free/open software.  You simply lose a lot of nice, desireable web functionality if you do.  At the end of the above article is a quick write about Gnash, the open/free flashplayer (though lacking a lot of functionality/compatibility) and how it handles flash cookies.
