Extension for Firefox and Thunderbird that displays and manages lists of date-based reminders and ToDo's. ReminderFox does not seek to be a full-fledged calendar system. In fact, the target audience is anybody that simply wants to remember important dates (birthdays, anniversaries, etc) without having to run an entire calendar application.
ReminderFox helps you manage reminders, ToDo's, and other tasks. ReminderFox adds an icon to your application -- a ribbon tied into a reminder-knot. By default this is shown in the status bar, but can be changed via the options. The ribbon will show any current reminders for the day. Hovering over the ribbon will show a snapshot of your upcoming reminders and ToDo's.
Right-clicking on the ribbon will bring up a list of available context menu options. From here you can go to the ReminderFox options as well as a number of other operations.
