Anyways, thanks for the hint, I'll try the about:config change. Sounds like something that might even be added into /etc/iceweasel/pref/iceweasel.js so it (positively) affects all users without having to mess with their individual configuration files.
Just played around with this for a bit and it seems to work:
grep -q 'lockPref("plugins.force.wmode", "transparent");'
/etc/iceweasel/pref/iceweasel.js ||
echo 'lockPref("plugins.force.wmode", "transparent");' \
/etc/iceweasel/pref/iceweasel.js
