I switched to the official Debian contrib package that directly downloads the, now again available, 64bit flashplayer plugin.
Code:
flashplugin-nonfree 1:2.8.2
youtube works. imdb doesn't, but at least it doesn't freeze the browser/system any more.

Do a
Code:
sudo dpkg-reconfigure flashplugin-nonfree
or a
Code:
sudo update-flashplugin-nonfree --install
