Used to work great but recently only shows mobile view of calendar :(

Edit: ThunderCal still works - https://addons.mozilla.org/en-us/thunderbird/addon/thundercal/

Now only displays mobile calendar :( Rated 3 out of 5 stars

This tab used to work great. As of relatively recently (even before the upgrade to Thunderbird 24), it started only displaying the MOBILE interface to the calendar (i.e., an agenda view with a very limited interface). Perhaps Google changed their criteria for what browsers see what view. Either way, this app should somehow force the Desktop view of the calendar.

Perfect Rated 5 out of 5 stars

Thank you! It works perfect!

Good Stuff Rated 4 out of 5 stars

Great little add-in. Works better than lightning without the bugs, simplifies the synching issue between desktop and android calenders well.

Love it but... Rated 3 out of 5 stars

Love it but I am having an issue with all event displaying. Apparently if a user that I have shared my calendar creates an event, it does not show up in Google Calendar Tab. It shows up on my Google Calendar page just fine. Please fix this problem and I will easily give you a 5 star rating.

Great add-on Rated 5 out of 5 stars

This is seriously useful. Far better than lightning. Excellent add-on, thanks

Better than Lightning Rated 4 out of 5 stars

Not as feature rich as Lightning, but not as buggy or annoying as Lightning either. Easily the most effective and reliable calendar integration available in Thunderbird.

Add Tasks Please - One More Vote Rated 4 out of 5 stars

One more vote for getting tasks to work. This is a perfect add-on for Google Calendar, but PLEASE add the tasks to the tasks pane.

Adds Convenience Rated 5 out of 5 stars

I love the convenience of this add-on because I can check email and immediately add appointments to my calendar which is than synced with my smartphone, laptop and tablet.

This user has a previous review of this add-on.

Tasks List is blank Rated 2 out of 5 stars

Before updating TB to v13.0 my tasks list was blank and now my tasks list appears but no calendar ???? Problem seems to have been that the extension option had been set to GOOGLE APPS FOR YOUR DOMAIN
<span> URL: "<a class="smarterwiki-linkify" href="https://www.google.com/tasks/android">https://www.google.com/tasks/android</a></span><br>Setting to GOOGLE CALENDAR now displays the calendar correctly and blank Task List.

Multi-calendar problem Rated 4 out of 5 stars

this add-on is fantastic and full-fills quite all (my) needs, except for a small bug: it is not possible to move from one day to another by mouse the events of the secondary calendars, this is possible only from the main/first registered calendar.

Brilliant in its simplicity Rated 5 out of 5 stars

Well done -- the calendar you use, where it's most useful. Thanks.

Was working great Rated 3 out of 5 stars

Use this add-on at work and at home, does what I need it to do when sharing calendars. Until it just stopped working, hangs on the loading screen. I have guys that have no issues using it with TB v7-9. Why mine just stopped I have no idea.

No todo list

Can use RTM as todo list Rated 5 out of 5 stars

Google task won't show, but good things is Remember The Milk has a Google Calendar Sidebar Gadget: https://www.rememberthemilk.com/services/googlecalendar/sidebar/
The RTM Sidebar Gadget can be a great replacement for Google Task. And the best thing is it shows perfectly in Google Calendar Tab.

With the help of RTM's Sidebar Gadget, this addon becomes a killer addon for GTDer. Now I can see my emails, Google Calendar and Remember The Milk in 1 place.

Awesome Rated 5 out of 5 stars

Great add-on, simple and effective! The only issue is that the Google Tasks list next to the calendar is just blank. Fortunately, the tasks are shown correctly into the calendar itself.

Doesn't display ToDo list Rated 4 out of 5 stars

Great Addon, but why doesn't it display the ToDo list right next to the calendar? There's just a white space.

This review is for a previous version of the add-on (3.8). 

Rated 4 out of 5 stars

Great fix for printing as Lighting doesn't allow you to print a daily calendar showing a full day of time. Just gives you a list of your daily appts. The printout that Google gives you for a daily calendar is what we are looking for.

For those with Thunderbird 7 issues, you can go and edit the install.rdf embedded in the install file using something like 7-zip. Change the <em:maxVersion>7.0.a1 to <em:maxVersion>7.0.* and then save and click yes to update the update archive pop up and then re-install.

This review is for a previous version of the add-on (3.8). 

Great Addon ! Rated 5 out of 5 stars

Best Google Calendar App I know. Please make sure to provide the Update for Thunderbird 7 to make this Addon perfect.
