Rated 4 out of 5 stars

Cool extension that needs a "little" enhancement to be perfect : a ReminderFox Server, to share reminders between computers, like what do foxmarks for bookmarks.
here is an example : i add some events at home, i close firefox, ReminderFox sync with its server, later at work, a get notified for upcoming events. and if i use another browser, i connect to ReminderFox server to see my events in a web page. Thats all. easy :p

good luck.

This review is for a previous version of the add-on (1.7.2). 

Hi Morrocan, you can indeed share your calendar between multiple computers and versions of ReminderFox. Check out: http://reminderfox.mozdev.org/faq.html#s6

Hope that helps.
