Flash Player Install?

[rajibando]

Flash Player is pre-installed in Google Chrome and updates automatically!
You could check whether Adobe flash player is installed at http://helpx.adobe.com/flash-player.html
I don't remember which plugins Iceweasel of Knoppix7.0 contained, but the present versions have script blocking and ad-blocking plugins. Maybe they were there in 7.0 too? If they were, you could allow the scripts to run in your system by right clicking and enabling the scripts. There are a lot of options.
For installing Flash in Iceweasel you better try the above-described easy way of creating a plugin folder and just copying-pasting the libflashplayer.so in the folder. Then start Iceweasel.
I am sorry I could not be of much help. You might already have tried these avenues. Maybe my reply would even be found irrelevant when the real problems are detected.
