Please do an update for those of us using the Lunix versions. Currently 3.1.12 is not supported.

This review is for a previous version of the add-on (0.8). 

What Linux distribution are you coming from that still makes use of tb3.1.12 ? You need to look for the "Older Versions" link on the provider page, as addons.mozilla.org only allows one version to be shown at a time. Due to platform changes I can only support a few versions at a time.

Does not work in the latest Thunderbird version 3.1.12. Please upgrade as I need to view multiple calendars.

It works perfectly, and I couldn't live without this add-on. I recommend it to everyone who wants to keep their calendars synchronised.

The only thing that would complete it is support for Tasks, but I note that it's being worked on already.

Loving it! Having all in Thunderbird for me is a blessing (Gmails, Calendars) I'm just missing the Task which I know you are working on. Keep it on! Great Job!

Thanks for your super Add-on! I like it very much. Easy to use, but I have a question. Can you make the same for Zoho Calendar. I mean also a provider for Thunderbird. Zo I can use Zoho & Google calendar in Thunderbird.
I didn't saw any pm possibility, so I did it this way. Like to hear from you so i can set up an account for you.

Hi! Unfortunately I will not be creating a further extension that works with Zoho since creating a provider to perfection is a substantial amount of work. But, this doesn't mean there will be no chance! Take a look at: https://forums.zoho.com/topic/caldav-support it looks like Zoho is working on CalDAV support, which is supported natively within Lightning. Maybe you can ask them to give an update on their current status.

This addon worked very well but since a few days, it started to ask my password(s?) for each calendar. Even if I checked the remember box, it doesn't remember anything.
I make a rate of 4/5 because I used it since the beginning and I love it.

I love this addon! It can be greater if there is a sync for offline use!

I suggest/support 3 future developments :1) a real sync. - i.e. a local copy of the agenda to work off line (it might be already available ?)2) a sync. of the tasks3) a better integration of the alerts.
Edit : revised based on Philipp's answer

This review is for a previous version of the add-on (0.7.1). 

A real sync is already possible using the Experimental Cache feature of Lightning. I am working on Task Sync, bear with me. Also, the alert integration is something to be solved in Lightning itself and not in the provider. I'd appreciate if you could revise your review based on this! Thanks :)

My apology. I missed a rather important step. This works 100% FLAWLESS and I apologize for my previous review.

Works well, but stops working when Thunderbird or Lightning update (automatically in my case). Current version is not operational (when attempting to update, an error message appears, stating it is incompatible with Thunderbird 4.0) Besides, would love it to work when not-on-line (e.g. synchronizing when coming back on-line)

This review is for a previous version of the add-on (0.7.1). 

Unfortunately I cannot support every version of Thunderbird, 4.0 was never released. All stable release versions of Thunderbird are supported by this or a previous version of the provider.

Full offline sync is being worked on in Lightning and readonly offline support is available via the experimental cache feature, also in Lightning.

I'm finding this a great tool for keeping my Lightning and Android calendars in sync. It's really handy to be able to enter details either on the phone or in Lightning.

I love this add on! It syncs all of my google calendars. I've been using it for over a year now with no problems. For the other reviews that ask "why do I need this?", it allows BIDIRECTIONAL access to your google calendars. Otherwise it's just read-access only.
Love it!! ;)
