icedtea-7-plugin no longer correctly configures plugin in firefox

[Tessa]

After upgrading from 14.04 to 14.10, applets no longer work correctly in Firefox. Looking at the icedtea-7-plugin package, it no longer installs anything into the Firefox plugin directory:

$ dpkg -L icedtea-7-plugin
/.
/usr
/usr/lib
/usr/lib/jvm
/usr/lib/jvm/java-7-openjdk-amd64
/usr/lib/jvm/java-7-openjdk-amd64/jre
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
/usr/lib/mozilla
/usr/lib/mozilla/plugins
/usr/share
/usr/share/doc
/usr/share/doc/icedtea-7-plugin
/usr/share/doc/icedtea-7-plugin/copyright
/usr/share/icedtea-web
/usr/share/doc/icedtea-7-plugin/changelog.Debian.gz

Please revert package install location behaviour to the same as 14.04, so that Java still functions correctly in Firefox when the plugin is installed.

Status changed to 'Confirmed' because the bug affects multiple users.
