Rated 4 out of 5 stars

A very usable "remind me - calendar style" App, and one worth installing, using as much as prudently possible and keeping over the long-term. Very usable features, few if any "stay in your face" when you don't want them to, and those that you need are very useful indeed.

Only real "negative" seen here: Versions prior to ReminderFox 2.1.5.4 MAY make Firefox version 43+ Add-On unit call "...can not be signed and is disabled..." errors, generally easily fixable by updating to version 2.1.5.4 or greater.

This review is for a previous version of the add-on (2.1.5.4).
