Since google no longer bundles its pepperflash plugin with chrome's debs (<a href="https://bugs.launchpad.net/ubuntu/+source/pepperflashplugin-nonfree/+bug/1632870">bug #1632870</a>) the recommended way to get the plugin is by installing adobe-flashplugin from the partner repository. However, since it also includes the outdated NPAPI-plugin this will result in two flash-plugins being installed to Firefox' plugin directory, due to the fact that browser-plugin-freshplayer-pepperflash and adobe-flashplugin doesn't use the same alternative link, which they should.

In /usr/lib/mozilla/plugins there's currently two links:
flash-mozilla.so -> /etc/alternatives/flash-mozilla.so (installed by browser-plugin-freshplayer-pepperflash)
flashplugin-alternative.so -> /etc/alternatives/mozilla-flashplugin (installed by adobe-flashplugin)

browser-plugin-freshplayer-pepperflash should use the same alternatives-link as the official package but with an higher priority, which would eliminate the compability issue.

Also the recommend of pepperflashplugin-nonfree should be removed and solely recommend adobe-flashplugin instead.
