multiple logins Ohodnoceno 3 z 5 hvězdiček

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 Ohodnoceno 3 z 5 hvězdiček

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.

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 Ohodnoceno 3 z 5 hvězdiček

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. Ohodnoceno 3 z 5 hvězdiček

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 Ohodnoceno 3 z 5 hvězdiček

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 Otherwise it is great extension.

How to make it work and get rid of multiple master password prompts Ohodnoceno 5 z 5 hvězdiček

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 ( 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:

Works for me!!! Ohodnoceno 5 z 5 hvězdiček

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 Ohodnoceno 1 z 5 hvězdiček

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. Ohodnoceno 2 z 5 hvězdiček

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 :(

I use Google Calendar with Lightning. The extention does not memorize some recurring events and synchronizes not well anymore. Altough when they are correctly memorised in Google portal. Please, fix this bug.

Please refrain from using the reviews for support requests. Given there have been some issues I am ok with the one or other low-star reviews, but in all of your 4 reviews you have been complaining about sync issues. Don't you think one would have done it, plus maybe contacting me via email to get your issues resolved?

Ohodnoceno 5 z 5 hvězdiček

This is probably a good product (I don't know yet, because I've just started using it) but it REALLY REALLY needs some clear, simple installation instructions. I spend an hour trying to figure out how to use this thing. (I know the provided instructions seem clear to the author of the software, but they were anything but clear to me.)


The product author was very responsive to the installation problem I had, and is probably going to take some steps to make the process clearer. In addition, I've been using the product for a while now and it has functioned flawlessly. As a result of these things, I've changed my review from 1-star to 5-stars.

Hey Harry, sorry it turns out to be so complicated. Please contact me via email so I can better understand which part is causing trouble.

Perfekte Verwaltung von Kalender und Aufgaben Ohodnoceno 5 z 5 hvězdiček

Ich benutze das Add-On jetzt schon mehrere Jahre und bin sehr zufrieden. Anfangs hatte mir noch der Support für Aufgaben gefehlt, der inzwischen auch vorhanden ist. Google Kalender laufen über das Add-On absolut stabil und ich kann meine Termine einfach verwalten. Vor ein paar Monaten gab es mal kurzfristig ein paar Probleme, da der Entwickler auf eine neue Api von Google wechseln musste, da Google ja leider regelmäßig seine Dienste ändert und das das Leben von Entwicklern alles andere als erleichtert. Aber nach ein paar Anfangsproblemen, bei denen man nicht mehr zuverlässig auf den Kalender zugreifen konnte, wurde das jetzt auch gelöst. Es ist jetzt sogar viel komfortabler, da man nicht mehr die Kalender-Adresse aus dem webbasierten Kalender in Thunderbird rüber kopieren muss, sondern direkt aus Thunderbird heraus auswählen kann, welche Kalender aus dem Google Konto angezeigt werden sollen.

finally works good Ohodnoceno 5 z 5 hvězdiček

UPDATE: It looks that installing Startupmaster (, as Philipp suggested, solved all problems. This make me think that previous problems came from unfortunate Thunderbird design, so I'm changing rate :) Thank you Philipp for solution.

I had always problems with this add-on. Few was not too annoying, like spawning many master password windows, occasionally disabling calendars, asking for Google password every Thunderbird restart. Some very annoying, like inability to dismiss event alert. But today I had to remove it because it's got crazy and has broken thunderbird (it was spawning dozens of empty windows, disabling all extensions, asking for google password every minute). That was too much.

Please try installing the Startupmaster extension in addition to the Provider.

Ohodnoceno 1 z 5 hvězdiček

I absolutely hate this product! Every single time it "upgrades" it wipes the Google application-specific password and Calendar silently stops working. I am forced to reinstall all my calendars and recreate the credential.

I'm sorry about that, but I assure you that I won't be doing these kinds of updates on a regular basis. In versions 1.0 to 1.0.3 there have been some major issues where I think its better to upgrade all users. To do so, I have to disable the API key in the Google API console, which requires a re-login.

Once things are stable, I do not need to do such upgrades and your authentication will live over an update.

Note also, that generally it should be enough to log in again once. Recreating your calendars shouldn't be required. Please contact me via email for support in case its otherwise.

Calender works perfect but tasks do not update in real time even after manually syncing them. The delay makes it hard to micro manage tasks.

Please fix since it seems to become a problem just recently. Also it seems its only for receiving updates i.e. I make a change via my mobile and sync with google, but the change doesnt appear on the provider. IF i change the task on the provider it'll sync properly and timely with google.

Has been reliable for me for a while now since the big API changes. Thank you so much for making this. It makes my life much better. Even when it wasn't working great it was at least some way to access google cals from Thunderbird. Don't let the entitled complainers get you down.
