Please note that wget http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_10.2.159.1-0natty1_i386.deb gives an error 404 (Seems to be removed from the server)
Only the second solution works :
Download http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_10.2.159.1.orig.tar.gz
Copy the iin libflashplayer.so to /usr/lib/flashplugin-installer/
Note that the problem is related to the type of cpu you have.
dpkg -l | grep -i flash

Replacing the new library with the older version helps on this type of computer.

With the most recent package Firefox did nothing when trying to open video's or Google Streetview. Chromium reported an error in libflashplayer. After replacing the new library with the older one, Firefox is working ok. Chromium gives a warning that the
flashplayer is outdated, but if you ignore this warning Chromium is working ok again.
dpkg -l | grep -i flash
