[KUbuntu] Enable Thunderbird Notifications

Suddenly, Thunderbird stopped showing notifications in my Kubuntu installation. After trying several addons, tunning options and trying to debug the issue I ended finding the following sollution:

  1. Install libnotify in your system:
    sudo apt-get install libnotify-bin
  2. Install “Enhanced Desktop Notifications” Thunderbird add-on
  3. Done.

Now thunderbird will be using KDE Notifications.
