It's one of my favorite Firefox extensions for sure. The only issue I had with it is that the black font skin applies to everything but the agenda.

Can't get google tasks.

beautiful. best calendar i've ever used.

tres bon

Just what I've been looking for! Awesome! Thank you!

Awesome extension. So much useful! The only thing i needed was a custom snooze duration for Google Calendar and this gives it, plus a whole faster way of working with Calendar.

Early days but great so far. Only problem is that on the pop-up calendar, when I click on a day that has several events, they only pop up in detail for a second and then disappear.
I'm on multiple monitors if that makes a diff.

Dig it!

Doesn't Work, Keeps showing me "Network Problem" when I want to add my account.

This is such an awesome extension!

Do not work recently.

Great calendar extension, it supports Chinese lunar calendar. I love it.

Great addon. The only missing part is to display full notes for instance with video conference links when there are many people in the meeting.

Used for years with Chrome and it was awesome and kept fresh by the dev.

Simple to setup and use. Quick entry and view of appointments without having to open a new (Google) tab. Has all the functionality including reminders, multiple calendars on one calendar. Single button to open full screen mode. FAST response to issues. This is an add-on worth donating to.
