Lightning stopped working with TB 52.5.0 Rated 3 out of 5 stars

It's a great extension, but not really much good if it doesn't work. It was working fine after install on TB (on Ubuntu) but now throws a message that it is incompatible with TB 52.5.0. No other explanation and there seems to be others with the same issue.

This is just the kind of headache which stops folks moving away from Microsoft products. What a shame!

Thunderbird updates keep breaking Lightning - a fix of sorts Rated 5 out of 5 stars

I've ben using TB now for years and find it great. And I think Lightning is great too, hence the 5 stars. But everytime TB update they seem to break Lightning and that's indispensible to me. I've dozens of important reminders on there synced to my gmail account. As I write the latest TB release has broken it again. So I've downloaded TB 52.0 and turned off auto updating to get Lightning working again.
I'll have to check from time to time to see if Lighning is working on the latest TB before upgrading in future.

The most useful TB addon I've found Rated 5 out of 5 stars

Lightning is without a doubt, THE most useful addon that I have found for Thunderbird. I use it daily for scheduled appointments, and my go to calendar. My sincere thanks to the developers that maintain and enrich Lightning.

This user has 2 previous reviews of this add-on.

I am grateful that Lightning exists Rated 5 out of 5 stars

Together with Exchange EWS provider for work and SoGO Connector (CalDAV) for my personal calendar it fulfils my calendaring needs.

I like and depend on Lightning, it is quite realiable. Rated 5 out of 5 stars

A solid, feature rich calendar add on for Thunderbird. I depend on it to keep my poor (80 yr old) memory straight.
It has tasks and appointments. when a notice pops up I have a time minutes, hours, days, I can select before the notice pops up again.

I only have an issue with the Thunderbird developers who without warning removed Lightning in the last update, but do not always do this.
It was easy enough to find and reinstall it, but I should have been warned.
Lightning is just great.

Danke und Anregung Rated 5 out of 5 stars

Vielen Dank erst mal für dieses Tool. Super Arbeit.

Mir fällt es nicht auf, aber wenn es nicht da wäre, dann würd´s mir auffallen.

Eine Anregung habe ich.

Es wäre eine tolle Sache, wenn im Kalender auch terminierte Aufgaben angezeigt werden könnten.

Mich jedenfalls würde es sehr freuen und wäre für mich nochmal ein ganz fetter Pluspunkt für Thunderbird und Lightning

All day task Rated 4 out of 5 stars

One can set task date to "All day" by defining due moment, but not start moment.

However, it's strange to me that the check-button "All day" appears right after I pressed "Save and close" independent on start-finish dates specified. This check-button is invisible during editing completely. And with a blink of an eye one can see this button appears for a moment when task editor closes.

That's quite bad.

Unusable because of too many popups when using Lightning with CalDAV Rated 1 out of 5 stars

Sorry that this is kind of a rant, but my first use of Lightning for a while was quite the disappointment: When I try to sync my (ownCloud-)CalDav calendar, first, lots of notifications about past events pop up. I can click those away, so minor annoyance, but ok.

But then, apparently in a loop, messages appear about some changes being about to be synced to my server (I didn't change any of the events locally, so no idea why Lightning thinks they have changed, or changed them itself?). These messages keep on coming in a steady flow, making the program unusable. And even when I click through them (clicking the "Dont sync" option, as I didn't do any changes and therefore don't want anything to be changed, obviously), they reappare after a minute or so.

Meaning that with my CalDav calendar set up, Thunderbird becomes unusable because of reappearing popups.

I only did a quick search so far what could be the matter, but this behavior caused me to loose trust in Lightning, so I won't be using it again in the near future - why would it think my events were changed, or would change them itself? And even if there is a legitimate reason for that (which it should inform me about) why would it show a single popup for each of them? After the first one or two it should notice that it's got too many popups in the queue and just stop and ask _once_).

All day caldav tasks Rated 4 out of 5 stars

Great tool, but I can't create all day task stored in caldav server (NextCloud). Looks like all tasks need to have date AND time set. All day task has got only date.
Is there a way to do this?

Update issues Rated 1 out of 5 stars

Since Thunderbird is updated to 52.4.0 the plugin is not working anymore.

- Calendar Tab got no title
- The Calendar itself is not displaying. Seeing just a white Tab
- The Tasks-View flickers, no chance to edit anything

great Rated 5 out of 5 stars

great google integration

Worsening with age, indeed Rated 3 out of 5 stars

It is a fine idea and has a nice interface. BUT:
I have a GoogleCal with more than 2000 entries. (You may say, I shouldn't, but I do and probably many others as well. Google is apparently feeding these in time order, which means "most irrelevant first".) And I need to integrate a dozen other institutional calendars as well in my daily and weekly agenda.
This makes the plugin almost unusable, because:
* It takes too much time to download the iCal stream. Compared to the pure download time (with curl or wget), it is orders of magnitude longer. So the handling/decoding must be badly implemented.
* During download the whole application is stuck intermittently and issues a warning ("blocked script").
* There seems to be no caching of calendars.
Under these circumstances, this plugin supposes that Thunderbird is started well before (30'?) the productive work can begin.

awesome! Rated 5 out of 5 stars

been using this for long time with google integration. This addon is just perfect, i highly recommend to use this to everyone.

Thank you!

- using debian 8 and 9, 64bit - thunderbird latest and this extension latest.

Use the 5.4.2.1-candidate if you can't do without Lightning in TB 52.2.1 and can't wait Rated 4 out of 5 stars

A working candidate build is available at http://ftp.mozilla.org/pub/calendar/lightning/candidates/5.4.2.1-candidates/ just drop the appropriate xpi link in your Extensions tab in Thunderbird

No funciona en la versión 55 de Thunderbird Rated 5 out of 5 stars

Thunderbird disappears Rated 5 out of 5 stars

If you enjoy using Lightning with Thunderbird, don't allow Thunderbird to update. Lightning may not be supported, and your calendar is removed without warning!!

Rated 5 out of 5 stars

LIghtning - worse with age Rated 1 out of 5 stars

Latest Lightning a memory-leaking liability, must disable to keep Win Thunderbird process from steadily consuming increasing & obscene amounts of memory. Hard to know if add-on or Lightning<->Thunderbird interop at fault, but bottom-line is the pair are increasingly unreliable and unusable together.

Good luck! Rated 5 out of 5 stars

I have used TB and Lighting for a very long time. I'm happy, though sometimes it's not all right. Thank you to developers and I wish you a lot of luck in solving "I want it for free and immediately" requirements :)

Znakomity kalendarz Rated 5 out of 5 stars

Używam go od ponad 2 lat w firmie, gdzie panuje MS Outlook. Współpraca z Kalendarzem (z użyciem plugina Exchange EWS Provider) przebiega bezproblemowo.
