PomodoroFox Add-On for Firefox
PomodoroFox is a simple aid for Pomodoro Technique (http://en.wikipedia.org/wiki/Pomodoro_Technique) users. It blocks any access to a user-defined domain list, while a configurable timer is active. This timer is intended to be the pomodoro activity time, by default, 25 minutes. Timer is started by clicking a button on the toolbar. When time is out, blockings are no more applied and the user is notified.
