The best solution here is not to use non-free software as a general
rule, and stay the f*** away from non-free software peddled by companies
that have their software phone home to "". IIRC, Gnash,
the GNU swf decoder/player/interpreter/whatever, does not have these
flash cookies, and if it did, you could easily disable or find a way to
purge them. 

Really, though, a Torified browser should have as few plugins as
possible, to limit anonymity attacks and the general surface area for
other exploits.
