Hi, Unfortunately, it appears that the wrong package has been build, it does not contain the /usr/lib/mozilla/plugins directory.
$ dpkg-deb -c browser-plugin-freshplayer-pepperflash_0.3.4-2_amd64.deb drwxr-xr-x root/root 0 2016-02-13 23:57 ./ drwxr-xr-x root/root 0 2016-02-13 23:57 ./usr/ drwxr-xr-x root/root 0 2016-02-13 23:57 ./usr/share/ drwxr-xr-x root/root 0 2016-02-13 23:57 ./usr/share/doc/ drwxr-xr-x root/root 0 2016-02-13 23:57 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/ -rw-r--r-- root/root 563 2016-02-13 23:50 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/changelog.Debian.gz -rw-r--r-- root/root 3850 2015-12-20 14:38 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/freshwrapper.conf.example -rw-r--r-- root/root 26210 2016-02-13 23:57 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/img-missing-pepflash.png -rw-r--r-- root/root 2651 2015-12-20 14:38 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/README.md.gz -rw-r--r-- root/root 3743 2015-12-20 14:38 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/known-issues.md -rw-r--r-- root/root 1595 2015-12-20 14:38 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/changelog.gz -rw-r--r-- root/root 23350 2016-02-13 23:50 ./usr/share/doc/browser- plugin-freshplayer-pepperflash/copyright drwxr-xr-x root/root 0 2016-02-13 23:57 ./usr/lib/ drwxr-xr-x root/root 0 2016-02-13 23:57 ./usr/lib/browser-plugin- freshplayer-pepperflash/ -rw-r--r-- root/root 1061976 2016-02-13 23:57 ./usr/lib/browser-plugin- freshplayer-pepperflash/libfreshwrapper-flashplayer.so Configuration of the package still fails because of it.
