i've just solved the problem, flash plugin runs again. i'm using ubuntu 1310 64, so you'll have to translate following commands to your package system:
sudo apt-get install libnss3:i386
in short, i had to install libnss3 (that contains this libssl thing) in 32bit version. afterwards another bug occured, something with cURL, so i've solved it the same way:
sudo apt-get install curl:i386
and now all seems to work. good luck, hope it helps.
