Had the same "Requires additional items" problem as the last two reviewers. It happens because the version of Lightning in the Ubuntu repositories is too old. To fix it, firstly uninstall the package "lightning-extension" using either Synaptic or the terminal. (In Linux Mint, your system will say that a package called "mint-meta-gnome" will also be removed - it is safe to do so because it is a metapackage, i.e. it isn't a program itself, just a convenient way of installing a long list of other packages. The lightning extension is on that list, but removing it does not remove any of the other packages on that list.)

Next, install the latest version of Lightning from the Mozilla add-ons site, then install Google Provider, and you should be home and dry.

This fix is for Ubuntu and its derivatives such as Linux Mint, though I would guess that similar solutions exist for other distributions.

Mine isn't working. In the Add-ons menu, it says: "Requires additional items". That's all. I have Lightning installed. TBird is version 2.0.0.21.
My only add-ons are enigmail and lightning. Anyone have a clue what "additional item" it wants?

My system is an HP laptop (dv 1000 series) running XP sp3. My business and personal needs are fairly simple such as no invitations, attendees, etc. I have not seen the performance degraded issues reported by some.

It took me a while to figure out how to set things up, but everything has gone well after that hurdle.

If you have multiple calendars on your system, you have to be sure to make the entries within the G-calendar (my designation) as that is the only one synced to Google. Although it will pick up entries from those made in my home calendar with Thunderbird, these do not transfer to the Google calendar in the cloud, but I've merely moved over to running everything through the G-calendar as my default.

Great tool, but what I really miss is the option also to add extra calenders (without the necessity to obtain the friends-passwords), like you can do in Google Agenda.

The thing looks good and works well, although how to get the calendars to work took me a while to find! There the plugin could be inproved by having ALL the same things as google calendar so they can be used semlessly. Like the SMS notifications for example. Thanks..

I am totally beside myself with the fact that someone had the aptitude to write such a great program in concept, but failed to allow the calendars to simply sync with Google upon a keystroke instead of relying on a constant online connection to send the data back and forth between Lightning & Google.
As many others have complained, I have found that this add-on brings Thunderbird's performance down to a completely unacceptable and almost useless level.
Yes, I have checked the "experimental" caching box to be able to view calendars offline... not good enough.
Yes, I have tried making the calendars "read only", but who the heck wants that?
Make this add-on a REAL and USEFUL tool on the next revision by letting the calendars reside locally on the PC and simply sync with Google upon command. Fast, simple, useful, always available.

Maybe you want to join the Mozilla Calendar Project and help us improve performance? I can set you up with a few links to get started in development if you like

I was originally going to give the add-on only 3 stars because my thunderbird performance became so abysmal. However changing my calendars to read- only seems to have solved the problem. Hooray!
For reference, I have about ~20 recurring events per week or more, but I only have data out through May. I also have two public Google calendars imported as well (with relatively few items in each one). this is a relativity simple schedule compared to what I've often had in the past, so I'm hoping future updates will be more robust. Great product!

Works great for secondary calendars.

OK, since any answer comes from the dev I give my contribution for this question.
I've made extensive tests using both native remote calendar subscription and this extension.
The main difference (but not the only) I found, and it's fundamental, is that native subscription access the Google Calendar in read only mode, while the extension gives full write access.
It seems to works quite well

---------
As in title. Why would we have to prefer this addon instead of subscribing natively remote calendar with Lightning?
I think a clarification would be welcome

What's the advantage of using this plug-in versus natively using Google's CalDAV prototcol to access my Google calendar?

I don't get yet why one would need this plug-in ???

This review is for a previous version of the add-on (0.5.1). 

Google only recently added CalDAV access to Google Calendar. This plugin was created back in 2006/2007, where there was no other possibility than to use the API. I am also working on improving the CalDAV provider to work with Google, eventually this addon will provide any extra configuration options usually not available with CalDAV calendars (i.e adding guests and settings ACLs)

Also, Google's CalDAV support is not considered production ready, last I looked.

Ampers is an idiot.
You have to download Lighting 0.9 before it would work.

Really promising but a offline mode is clearly missing (ability to see events in the remote calendar is here but there is no way to update it or create new event in the google calendar while on the go).

Wow! This is so useful, and I've always written down everything I needed to do but then ended up elsewhere and needed remote access to my lists, sending myself emails but this is like a Godsend

Great plugin.
I saw today in google labs that Google released a Tasks application. Might be a nice to include in this plugin.

Very useful addon for all Google Agenda users.

Bidirectionnal sync work great.

Only 4 stars, because multiple agenda syncing causes a global thunderbird sloawdown every minute or so.

As a workaround, it would be interesting to be able ton configure frequency
