iceweasel amazon prime flash error

When trying to watch a video on Amazon Prime, I got the following error

Sorry we were unable to stream this video. This is
likely because your flash player needs to be updated.

To fix the error, install the following packages

Note:- Some of the packages might be unnecessary. But they are sufficient.

Make sure that the hal daemon is working.

Update the flashplugin

$sudo update-flashplugin-nonfree --install --verbose

Close iceweasel window.  Remove the ~/.adobe , ~/.macromedia directories

mv ~/.adobe ~/.adobe_old_deleteafter
mv ~/.macromedia ~/.macromedia_old_deleteafter

Restart iceweasel. The video (and audio) should be working now.
