Exactly what I was looking for! Thanks!

I can see the events anymore after changing my background colour theme. The alerts are starting to be annoying; it should be the defualt push notifications of Mozilla, and least nut not last it was slowing down the startup of the browser. For all those reasons I just stopped using it; I prfer having the Calendar page always open.

when I first used this addon I found it very usefull. Until it started showing notification popups. There was no way to discard them, they kept coming. Apparently I should pay a contribution to get the 'delete' icon turn from grey to black and make it active. So I payed. After that the delete icon disapeared all together. So I got stuck with ongoing notification popups from events allready passed. I reinstalled several times, without result. Then I discarded the thing. I payed for 2 PCs. On both I got the same problem.

Fantastic! Even before unlocking the extra features by donating I've found this extension to be the best thought out of ANY extension I have ever used. Jason thinks like a user, not like a coder. It's obvious this software was designed for function and form FIRST, then coded to make what makes the most sense, WORK. Too many extensions and free softwares are coded without enough thought to how end users actually think and use things. When you tell them about issues they tell you you're using the software wrong. WRONG. Mr. Savard, you are a model developer all others should be required to learn from.

fantastic addon :D
An option to start the week at Monday would make it 6/5 :p

It was great until it started popping up way to frequently for no reason, and also the pop up was blank. Nothing on it. Just a white little window. I uninstalled and reinstalled but for some reason that won't fix it. I paid for this app on all of the computers here at the university...had to pay for it 5 times for each computer then 1 more time for mine. Mine is the only one experiencing this blank window error. This has helped the students so much in keeping organized and actually hearing the "CALENDAR REMINDER" notification loud and clear so they get up to check it. We never miss an appointment now. Thank you for this app. Please fix the issue.

the Best add ons!

There was a small problem. I use portable firefox 60.0.1 at home and at work. They have your extension installed. When you start the browser at work and when the notification window for past events appears, firefox closes without any error messages. And this happens if you do not have time to close the notification window manually and then not always. I do not see such problems on the PC at home. Perhaps it's worthwhile to make a timeout for displaying notifications right after firefox is enabled?

Date view and time of next event can´t be viewed simultaneously.
Time of next event: last digit is missing

TypeError: can't access dead object (js/jquery.js 307)

This is the resaon I give 3 stars. Using Firefox 59.0.2 (64-bit) on Ubuntu 16.04 LTS

I love this extension! Lets me quickly see if there's an upcoming event & clicking on it opens my calendar. That's all I need!

Перестало работать (установлена последняя версия расширения)
Показывает какую-то мешанину событий, июнь в феврале и т.п.
После нажатия кнопки "обновить" в панели расширения, вообще практически все события пропали. На весь год осталось штук пять событий
Проблема в режиме Расписание. В остальных режимах все нормально.
---
Начался февраль и расписание исправилось
Какой-то баг у вас в расписании января
---
Stop working (the latest version of the extension is installed)
It shows some hodgepodge of events, June in February, etc.
After clicking the "update" button in the extension panel, in general, almost all events disappeared. For the whole year, there are five events left
Problem in Schedule mode. In other modes, everything is fine
---
February began and the schedule was corrected
Some bug you have in the schedule of January

When I went to FF 57, I needed a replacement for Reminderfox. This product does the job. It has an option to display in list format which is what I prefer. My only quibble I that it doesn't present all of the Google Calendar options when I add an event. I have to press the button that goes to Google calendar. This is a very minor inconvenience. Google Calendar imported the Reminderfox ICS file perfectly. To get Google Calendar to work almost exactly like Reminderfox you do have to change the Google Calendar option for alarms. Keep up the good work. I will be making a donation today.

In order to add events at specific times via clicking the calendar, you have to donate money. If you try, you get a popup stating that "These dimmed out options are extra features I spent a lot of time developing. To unlock these features, contribute ANY amount in support of my work." I initially thought it was a bug until I went to the donate page, lo and behold, under the extra features "Create events by clicking in the calendar" So, in short to add events I still have to go into google calendars to add events...This entirely defeats the purpose of even having the addon.

This is a real shame because this is otherwise a very solid add-on, but the inability to add events is a game breaker for me. Especially since it was a prior feature.
