It is possible to use gnash on the place of flashplayer with midori.
I am under Mageia 2 with midori-0.4.4 and gnash-0.8.9.
By installing these two packages, I can read no animation
gnash is intended for use in flash v10.0 or less, for 10.0 or more use lightspark (and them fallback to gnash for older versions ov flash)
