Install Pepper Flash Player
Pepper Flash Player is maintained by Google, and is newer than Adobe Flash Player. Download the newest .deb package:
# wget http://ftp.uk.debian.org/debian/pool/contrib/p/pepperflashplugin-nonfree/pepperflashplugin-nonfree_1.3_amd64.deb
If the file above cannot be found, check this link for a newer version. Once you have the file, install it:
# dpkg -i pepperflashplugin-nonfree_1.3_amd64.deb
If you check the plugins section on Chromium, you should see something similar to the following:
