There's only 24 hours in a day and it doesn't seem to get any longer or shorter (last time I checked). Managing your tasks and date-related appointments are important.

Thankfully, I'm reviewing an extension this week to assist you with your time management.


ReminderFox is a Firefox extension that manages lists of date-based reminders and ToDo's all in one central location.

As stated on their site, it's not a full-featured calendar system like Outlook, but provides users with a way to track dates and time-related appointments and schedules, such as birthdays, appointments, and...oh yeah, anniversaries. Can't forget those...for health reasons.


ReminderFox is a little hefty at a little over 550K, but the time management system, I think, is worth it. After installing the extension and restarting Firefox, you'll see ReminderFox in your system tray.

ReminderFox status bar tooltip


With ReminderFox always in the status bar, you always have a quick and easy access to your to-do list or appointments. Double-clicking on the "reminder string" opens the main dialog box.

The main dialog box shows your reminders and your ToDos. You can also add your own tabs to ReminderFox for categorys. If you have a list of birthdays in the office that you need to keep track of, this would be a perfect candidate for a tabbed reminder. This is discussed more in the configuration section below.

On the bottom of the dialog box, you'll notice the "Add Reminder" button, the search bar, filter dropdown, calendar toggle, and a revert and OK button. From using ReminderFox on a daily basis, I've always had to use one of these functions at least once. As a matter of fact, I always keep the calendar on mainly because I want to believe its Outlook. ;-)

Adding a quick ToDo or reminder is really simple. The add dialogs are just as thorough as the extension, but don't let them intimidate you. If you want to set up a ToDo or reminder, these dialogs definitely have everything you are looking for.

Right-clicking on the reminder string displays the context menu with a couple of speed options so interacting with the dialogs boxes are limited to a couple of entries. Excellent speed options.

One speed feature is the Quick Alarm on that menu. When you want to set up an alarm fast, type in the important times, click OK, and you're off. As soon as the time is up, you receive a dialog box alerting you to the alarm. The dialog box is complete with a snooze button as well.

When you are in the reminder or ToDos dialog box, right-click on an entry to get details or double-click to edit the entry.


ReminderFox's configuration dialog is quite extensive and can't be covered all in one post. I'll briefly cover the amount of material in the configuration dialog box. For more detailed explanations, I will refer you to the FAQ on their site.

ReminderFox display Screen

The configuration dialog box is sectioned into the following areas:

  • Display - Where do you want ReminderFox located on the status bar and what do you want displayed when you hover over the extension icon?
  • Tooltip - When the tooltip is displayed, what format do you want to use for your reminders and ToDo's?
  • Notifications - Do you want the alert slider to notify you, or a sound to play, or both?
  • List Display - This tab allows you to select the starting day of the week, the Date and Time format, and whether you want all repeating reminders to appear or the next or previous occurrences.
  • Defaults - Here you select your default options for new reminders and set the default for the completed items in your to-do list.
  • Lists - This is where you want to set up your category tabs for birthdays or appointments as I mentioned above. However you want to organize your tabs, you have complete control over the categories.
  • File - This tab allows you to export and import your data file to a directory.
  • Network - The network tab takes the File tab to another level and allows you to send your data to network destination for sharing purposes or allow you to use multiple PC's with one reminder data file.

I firmly believe its better to have more of something than less. ReminderFox's configuration is organized in a clean, intuitive way and shows that a great deal of work went into this part of the extension.


I've been using ReminderFox since I reviewed it the first time and with every update I receive, I've never had a problem with the extension. I've never encountered any problems regarding functionality and it's stable since the day I downloaded it.

If you couple ReminderFox with a portable version of Firefox, you'll have a powerful, portable reminder system on a USB drive.

Overall, I really like the way it's set up and how everything "gels" together nicely. ReminderFox's ability to extend the interface through customization is a definite plus.

ReminderFox receives a 5 out of 5.

See ya next week.
