Comment 16 for bug 1068662

I have upgraded from 12.04, and it doesn't work for me neither.

When I visited Gmail it prompted me if I wanted to install the webapp, which I chose to do, and I can find it through the Dash. But it doesn't appear in the Launcher when I launch it. And I can't manage to get any other sites (such as Twitter, Facebook, Reddit) to ask me if I want desktop integration. And when I open the preferences window in Firefox I can't find anything about desktop integration. Apparently you should be able to see this in the preferences window: http://1.bp.blogspot.com/-QxPXtxj4Wes/UGZfb4sUU4I/AAAAAAAAKas/FZc920qnAzA/s1600/webapps-firefox-exceptions.png

I installed Twitter through the terminal (unity-webapps-twitter), but I couldn't find it through Dash and I couldn't see any difference when I visited the site.

However, I have reinstalled Firefox, created new profiles, installed and removed Firefox Aurora from Mozilla's PPA, etc. So maybe I have managed to break something along the way. I'm running stock Firefox (version 16.0.1) from Ubuntu's repository now, but is there something else I should try to reinstall?
