@8basepairs, I have updated my system, both through the terminal (sudo apt-get update ; sudo apt-get dist-upgrade) and through Ubuntu's Update Manager. Everything is up-to-date, (including version 16.0.2 of Firefox). I still can't see any Desktop Integration in the Preferences window. I also installed the Grooveshark webapp through the Software Center, and it didn't appear in the Dash or in the Launcher, and when I visited the site I didn't get any desktop integration.
