i use this with postbox and it's a good idea ... until it just stops working. this (in concert with lightning) pulls in my calendars and i'm able to use it pretty much flawlessly for about a day after installing. then, suddenly none of my events appear on the calendar. they are all still in my google calendar. all of my calendars are still listed in the postbox calendar window, with the boxes checked, indicating i want them shown ... but the calendar itself is totally blank. if i remove and reinstall it, everything comes back. for a day. then 'poof' it's gone again.

THis add-on has been very useful for me for a couple of years...then Thunderbird updated itself to version 24.5.0 just yesterday...now this app crashes Thunderbird. I'd write another review with five stars if this developer fixes the bug, but it seems pretty useless at the moment for Windows 7 users...anyone else have this problem, or is it just me?

Great utility. What Microsoft shou'dve done for Outlook Rated 5 out of 5 stars

Since moving to the Mac universe and the iOS universe I have searched in vain for something to sync Outlook for Mac calendars across machines. Enter Thunderbird, Lighning Calendar and Provider for Google Calendar.

Works great. A bit fiddly to set up, but once done, works well. Offline functionality still a bit wonky as it seems that all data is loaded from the "cloud" on startup of T'Bird. Maybe wrong, but that's how it seems.

Now my cals on the Mac Mini, Macbook Air, iPhone and iPad are all sync'ed. No need for the basic "iCal" on the MacOS platform which is somewhat basic.

Wow - talk about BAD INSTRUCTIONS from the developer of this. . o O ( sigh )

I was correct (for the most part on my thoughts - that the instructions were seriously missing something.)

Follow the instructions from the below LINK and it will work! :D I just had my calendar get ALL my appointments and such from Google Calendar!!

https://support.mozilla.org/en-US/kb/using-lightning-google-calendar

Again - follow it carefully and it will work.

I'm still giving it a LOW RATING - because the developer should have known this from the start and/or at least LINKED us to this site.

What is the URL? Rated 1 out of 5 stars

Tried to use it. The doc said:
1 Open your Google Calendar -- OK!
2 Click on the Settings link located in the box at the right of the page. -- OK!
3 Click on the calendar you want to use with Thunderbird Lightning or Sunbird. -- I've just one ?
4 Click on either of the two XML buttons shown at the bottom. -- Never seen an XML button!

Does work... Rated 2 out of 5 stars

Does work but... completely stalls Thunderbird on startup IF connected to the internet. starting with disabled internet-connection first, than enable the net, everything works fine for me. Win 7, TB 24.3.0, Lightning 2.6.4.

doesn't work since last lightning update Rated 1 out of 5 stars

since the last lightning and thunderbird update (I am using kubuntu), thunderbird ist freezing about five seconds after start, if this plugin is activated. After deactivateing this plugin, thunderbird is working well, again.
At the Blogsite of Philipp Kewish the last entry is from 2013, September, so I think, there is no longer support for this plugin.
I am very sad about this, because the plugin was the only one, to be able to synchronisize and handle offline the google calendar.

Waiting for an upgrade to fix the "offline bug".

Fonction très utile mais ne marche pas en mode offline, car il fait buger thunderbird quand cette fonction est activée.
Bien mais en attente de ma mise à jour

Excellent tool - and it DOES work with Google 2-step auth Rated 5 out of 5 stars

I've been using this for a good year or so now and it's excellent at integrating my Google calendar with Thunderbird. Anything I add, whether it's in Thunderbird, on my phone, iPad or on the GMail website all get synced across all devices.

For the users who complain it doesn't work with 2-step verification and they have to keep entering their password... that's the point of 2 step verification, numbskulls! You need to log in to your Google account and into the security settings and set an application specific password to use! This will be given to you, a 16 digit code that you should use only for one application and can easily revoke by logging in to the same page.

Awesome tool. Many thanks to the developer! :)

It's an excellent add-on, it just needs an update because it's now broken Rated 3 out of 5 stars

I'm not sure if the mismatch is due to Lightning's latest update (Dec 2013 as of right now). I get a complete hang within 30 sec of loading Thunderbird, and it just keeps freezing.
I admire the developer's work, and since I I don't have the knowledge to do the same (or edit the extension), I'm now using the Google Calendar Tab which serves my purpose anyway. I can't do things offline but since I want to stay synced with Google Calendar (I use it on my phone, etc.) it's okay. And I'll keep an eye out to any update from this extension.

As always, when something is provided free and it's something I have no way of reproducing myself, I am truly grateful to the developer for having gone this far and all the efforts that have been put in this extension until now!

No longer works Rated 1 out of 5 stars

TB24.0.2, Lightning 2.6.4, Provider 0.25
This used to work perfectly. Now since December, Thunderbird freezes on opening and can only be opened in safety mode. Disabling Provider enables TB to work again. Come on - please fix it - clearly I am not the only one having problems..

Rated 3 out of 5 stars

Have used this add on for a number of years and loved it. Now not so much. Not all of my events sync and when I add them from Thunderbird they disappear never to be found again. I used this so I could keep up with appointments of other family members. What can be done to correct this problem as it makes no sense to use it if it will not sync all of my appointments or lose my appointments.
