I am no longer making enhancements to this add-on. This is the final product.
Bug reports should be submitted to my e-mail address (see "Support E-mail" link to the right). Using the reviews to report a bug, never to return to see my reply (usually asking for more info), rarely helps.
Also, please do not use the reviews to report errors when downloading the extension. That is not a problem with the extension, but with one of the AMO download mirrors. Please e-mail me instead.
Downloading this extension places a blue alarm clock icon in your toolbar (Firefox 29+).
After installation, if the icon is not visible, click the menu button at the far right of the toolbar, then choose the Customize option at bottom of menu, then choose Exit Customize option at bottom of the menu.
Features are available via a context menu (right-click on icon). Two modes of operation are available, clock and timer.
Clock mode displays the time and/or date in the format of your locale. The format can be customized to your liking.
Timer mode has three functions:
1. Count up from zero.
2. Count down from any time (less than 24 hours). You can set as many
timers as you want.
3. Select a specific time of the day to receive a notification. You can also
specify the day (daily, weekdays, weekends or a specific day).
You can set as many notifications as you want.
