Review for ReminderFox by Cyril Malka
Rated 1 out of 5 stars
Totally unusable interface, numbers and dates written over each other (I believe it's the datepicker) so it is unusable. It might make Thunderbird (68.4.2) go down. Maybe interfering with other add-ons and that's the reason. I don't know. I just uninstalled it *very* quickly when I saw that.
