If you are using the Lightning addon for Thunderbird, this addon is a must. A great way to ensure that you can access your calendar no matter where you are, but still have full control with Thunderbird.
Causing errors Rated 1 out of 5 stars
For the past couple of days this extension gives an "Unresponsive Script" error every time I load Thunderbird. The error actually says something about loading a month in Calender (Lightning) but if I disable Provider the error goes away.
Rated 1 out of 5 stars
After working for some time, this addon fails now completely.
It opens a window to ask for the google credentials everytime I start thunderbird.
For whatever reason non of the buttons nor the return key will ever submit the entered credentials. The buttons a simply dead.
After wasting hours of my lifetime to find some solution I dropped that addon.
Just what was needed Rated 4 out of 5 stars
This met my need to include subscribed (third party) calendars that were attached to my Google account. This included other users calendars and Podio.
Previously, I had been using CALDAV, but it does not give this level of granularity.
Here's how to fix the password problems Rated 5 out of 5 stars
Google changed their authentication regime. If it keeps asking for a password you need to go right-click on your calendar in the left-hand pane, delete it, and then set up again. Like so:
(1) First off, if you already have a Google Calendar set up in Thunderbird, delete it. Right-click on the calendar and select delete.
(2) Right-click on the empty space below "Calendar" in the left-hand pane.
(3) Select "New Calendar" and left-click that.
(4) Click "On the Network"
(5) Click "Next"
(6) Click "Google Calendar"
(7) Click "Next"
(8) If you already have your gmail account set up in Thunderbird as an email account, then select that gmail account from the leist you see here and click next. Otherwise, enter your full gmail account (including the part after the @ symbol).
(9) Click "Next"
(10) Google will ask for your password. Those of you without 2-step verification set up will want to read this: https://support.google.com/accounts/answer/6010255?hl=en
Those of you using 2-step verification need to read this page: https://support.google.com/accounts/answer/185833
(11) Select the calendars you have made and/or subscribe to in your Google Calendar account.
(12) Click "Next"
(13) Click "OK"
That's it, enjoy having access to your Google calendars from inside of Thunderbird/Lightning!
Keep asking for password Rated 5 out of 5 stars
I've been using this very good plugin for years but since a few days it keeps asking for my gmail password. :(
Dangerous Rated 1 out of 5 stars
The new version deleted some of the repeating events and the following synch deletes them on the server too.This user has a previous review of this add-on.
That doesn't sound good. Can you contact support?
always ask password Rated 4 out of 5 stars
every time i launch thunderbird, this plugin always ask me email and password of my gmail account, please solve it
Great product but.... Rated 4 out of 5 stars
since 1.04 I keep getting sync problems with Google Calendars - every appointment forces a dialog.
Down-graded to 1.03 which improves slightly but it's still there but not quite has annoying - still can't dismiss appointments and have to close dialog to get rid of it.
Are you working on trying to fix this problem or is this something local to my setup?
Rated 2 out of 5 stars
It is a pity, but I need to uninstall this addon. It worked fine in the past and was a really valuable tool, better than other options, but nowadays it needs for an adjustment. Multiple password requests and Thunderbird freezing problems decrease significantly the value of the addon...
multiple logins Rated 3 out of 5 stars
I'm using this add-on in an Arch Linux installation, and every time I start up Thunderbird I have to contend with at least three logins from Google. It doesn't seem to be able to remember my login information.
Became suddenly unresponsive Rated 3 out of 5 stars
This addon has been working very fine, but since a few days, it makes Thunderbird unresponsive. I tried everything: un- and re-installing the extension, Thunderbird, even moved from Linux Mint to Fedora 21 to Ubuntu 15. Always find the same behavior as soon as I add one google calendar. Something may have changed on Google side also.
Rated 4 out of 5 stars
Good but makes Thunderbird slow unresponsive and not responding very well.
I have 3 google calendars, including a shared one.
The script hangs, for instance, with the error Unresponsive Script in
Love/Hate relationship with this plugin. 1.04 Not synching properly Rated 3 out of 5 stars
1.04 simply is not working properly for me. It is not syncing all data from my Google Calendar. If I enter new entries directly on Google Calendar, it wont show up in Lightning.
Deleting the plugin, and re-installing it makes things worse. When syncing for the first time, less than half of the content on my Google Calendar will show up in Lightning.
Unfortunately, this is not the first time an update of this plugin causes problems with my Google Calendar sync.
HOW I FIXED IT: I reverted back to 1.03, and all is working fine now.
Had to reinstall the calendar, i.e., does *not* work reliably for me. Rated 3 out of 5 stars
No calendar entries in sight, so I followed the advice from a 5-star review here called "Works for me!!!". The author writes:
"I deleted the google calendar and re-added it and everything was back."
The same applies for me. But I don't share the opinion that this method means that it "works", or that it should be rated 5 stars.
If the plugin reliably shows the calendar entries and gives alarms, it *works*.
If the plugin at any time does *not* show the existing calendar entries, and/or misses to give an alarm - without warnings - it is not reliable and is frankly *not working*.
For a program to "work", it is not enough to "seem working for the time being". For software quality, there is a time perspective, there is a reliability aspect, and there can be a comparison with having a live person doing the job. Would it be accepted if a person behaved the same way, suddenly disappearing without a trace?
Apart from this, when it "works", it most often does its job quite well. Sometimes lots of old alarms come back, which is very annoying in the long run. All in all, 3 stars with lots of possibilities to reach 5! :-)
multiple password prompts Rated 3 out of 5 stars
There is very annoying bug since 2011 - a password prompt for every calendar, which makes the addon hardly usable if you have many calendars (see https://bugzilla.mozilla.org/show_bug.cgi?id=682474). Otherwise it is great extension.
How to make it work and get rid of multiple master password prompts Rated 5 out of 5 stars
There are quite a few people giving the developer of this add-on a hard time and bitching like he owed you something. Instead of complaining and insulting him, you should thank him. As far as I know he is doing this for free and I doubt that the occasional donation money will suffice for anything else than coffee.
I recently made the switch from an obsolete version of this add-on (before v. 1.0.x) to the most recent version (v. 1.0.4). The new version IS working and it is working fine. Better than the old versions, in fact. In order to make it work I did this: Completely remove all of your Google calendar subscriptions from Lightning and the stored password for your Google account. Then restart Thunderbird. Open Lightning and then File / New / Calendar / On the network / Google calendar. Then follow the instructions. A list with the available calendars of your Google account will eventually emerge and you can just choose by clicking the ones you wish to sync with Lightning. All of you haters must admit this is a lot more convenient than the old way of manually adding each calendar by clicking through a maze of settings in Gmail and then pasting in Lightning.
If you use a master password there WILL be a prompt for each of the Google calendars you have chosen to sync. This IS very annoying, but to some extent this bug has been plaguing Thunderbird for several years in various forms and it would be unfair to say that such a problem has only ever occurred with this extension. Nevertheless it is unbearable with lots of calendars. Luckily there is a solution, that the developer has already mentioned a couple of times: Install the extension Startup Master (https://addons.mozilla.org/en-us/thunderbird/addon/startupmaster). It will solve the problem and you will only be prompted for the master password once. This extension seems to delay the loading of the accounts, extensions and stuff until AFTER the master password is given by the user. This should be the default behavior in Thunderbird, but it is not. There are other extensions claiming to be able to suppress multiple master password prompts, but this is the only one I’ve tried that actually works and that won’t cripple the ability to sync the calendars.
So, all in all, here we have a guy who is dedicating his spare time to write an extension that will enable us to use Google calendars together with customizable open source software. It must be a pretty tedious and tiresome task to try to keep up with the constant changes in the Google API:s, but as far as I can see he has done a pretty good job. Google may claim that their continuous tampering is related to enhanced security, but that is probably not the entire truth. They are obviously trying to push people away from using anything else than their own browser by making it harder to employ the alternatives. Guys like the developer of this add-on are a healthy antidote to that. He’s doing a great job and he’s doing it for free. I lift my hat off for that and say thank you very much.
For anyone still longing for the old days when calendars had to be manually added, there is also hope for you. Check out post number 21 in this thread: https://bugzilla.mozilla.org/show_bug.cgi?id=682474
Works for me!!! Rated 5 out of 5 stars
v1.04 with Lightning 3.3.3 and Thunderbird 31.5.0 on Linux Mint 17.1
After updating to the current version I saw I had no calendar entries so I deleted the google calendar and re-added it and everything was back. HTH
Doesn't work anymore Rated 1 out of 5 stars
I can no longer see my calendar for google through lightening. I am running 1.0.4 on lightening 3.3.3.
Can you please provide any work around? I usually love this add on. Thank you
warning - this doesn't work with 31.5 stay on version 1.03 which works with it. Rated 2 out of 5 stars
This used to be a very good addon which was reliable. Quality and version control has slipped and stay on what you have if it works.
I will look at moving off this addon when I get the time. What a shame but enough is enough. Given two stars as in the past it was easily a 5 star :(
