1. I'm not sure it's a problem to have two versions of the Flash plugin, because one is the outdated NPAPI version:
> flashplugin-alternative.so -> /etc/alternatives/mozilla-flashplugin (installed by adobe-flashplugin)
and the other is the up-to-date PPAPI version wrapped by freshplayerplugin to look like a NPAPI plugin:
> flash-mozilla.so -> /etc/alternatives/flash-mozilla.so (installed by browser-plugin-freshplayer-pepperflash)
and I'm pretty sure that the browser uses the version with the highest version number. Still, it's messy.
2. Andrei Alin's version 0.3.6-1 of browser-plugin-freshplayer-pepperflash (ppa:nilarimogard/webupd8) fixes that issue:
> 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.
It does exactly that (thanks Andrei). However Ubuntu's version of browser-plugin-freshplayer-pepperflash comes from Debian, and adobe-flashplugin isn't available in Debian, so I wouldn't hold my breath for any compatibility issue with adobe-flashplugin to be fixed in the original Debian package.
I recommend using Andrei Alin's version of browser-plugin-freshplayer-pepperflash.
I agree with everything Niklas said. Two remarks:

and I'm pretty sure that the browser uses the version with the highest version number. Still, it's messy.
