Incessant freezeup make this unuseable. Rated 1 out of 5 stars

I agree with "I Give Up". A great tool but incessant freeze up makes it entirely unuseable. Sadly that leaves Thunderbird as only an email program not a full featured personal manager.

Lightning Install tip Rated 4 out of 5 stars

To vaid problem on MAC install both Lightning and Provider Google Calendar in order to work.

Workaround Rated 1 out of 5 stars

Oddly, it seems to work when the Lighbird addon is installed & enabled, Using Lightbird means I have an insufferable popup window for my calendar instead of tab integration, but at least I have my calendar back ...

I Give Up Rated 2 out of 5 stars

Well Thunder bird updates and Lightning stops working again.

I expect it's fixable; but I've got a desktop widget that does a decent job of linking up with google calendar, so I think I'll go with that; and return Thunderbird to just being a mail client.

Incompatibilidad repentina Rated 2 out of 5 stars

Hace tiempo utilizo TB con Lightning. Siempre muy conforme, per con la última actualización de TB a la versión 47.0 lightning pasó a ser incompatible y perdí todas mis entradas de calendario. Si bien pasó ya un tiempo, parece no haber solución de momento. ¿Cuándo saldrá la versión de Lightning compatible con TB 47.0? ¡Si no fuera por lo sucedido, les daría máxima puntuación! Para mí es un complemento muy bueno, pero de momento imposible de instalar. ¡Qué pena! Ojalá haya noticias pronto . . .

Installed without warning, and breaks Thunderbird add-ons Rated 1 out of 5 stars

This add-on was added with a Thunderbird update without prompting me to approve. With the latest update of Thunderbird 45.1.1 one of my essential add-ons was broken. Thanks, Mozilla. Two hours of lifetime wasted while trying to detect the misbehaviour and repair addon functionality.

The solution was to disable Lightning. Do not (!) remove it because it might come back with the next update.

Mozilla staff: Stop giving me something I didn't ask for without prompting me.

It would have been interesting to know which add-on Lightning has broken. Lightning is now an integral part of Thunderbird and if the few UI elements it adds are really bothersome you can still disable it.

Great Product Rated 5 out of 5 stars

Have used it with dedicated CalDav Server as well as Google Calendar, no problems.

New version seams unsigned for TB 45.1.0 Rated 4 out of 5 stars

For some reason I cannot install the Lightning plugin because its not signed. Is there a plan to update the version so that it works with TB 45.1.0? That would be very nice because I use it daily. Thanks, Julian!

Calendar data to be stored on another drive Rated 4 out of 5 stars

I have used the software for a while now and I am very happy with it. Please provide an option to store the calendar data in a location selected by user (Thunderbird already has that facility). This will enable the users to save it regularly with other data. C drive is saved infrequently by most people and moving the Tbird profile to another location is too complicated.

This is already possible, although maybe not as easy as it could be. There are two options, one would be to move your whole profile to a different drive, the other would be to use an .ics file instead of the local storage backend. The former would be preferable. Ask in support for details if you need help.

"Show Calendar Week" Rated 5 out of 5 stars

Bonjour,
Où trouve-t-on la case à décocher "afficher le calendrier de la semaine"? Je ne trouve pas.
merci pour votre aide.
Cordialement

Bonjour, the options is in Preferences > Calendar > Views, right next to "start the week on".

"Show Calendar Week" must be deactivated Rated 5 out of 5 stars

"Show Calendar Week" is no more nessesary with Lightning 4.7 and causes much trouble. E.g. the grid is empty, the menu is disabled (greyed out), etc.
If its possible, the author should deactivate "Show Calendar Week" automaticly, or at least give a warning.

Calendar grid empty after upgrade to TB 45 Rated 5 out of 5 stars

I love TB and Lightning is just perfect. However, now, we are getting into trouble: Lightning 4.7 is working (calendar on the side works and shows the entries, and all calendars are named on the left), but the main window with calendar grid is and stays empty. All buttons on top are grey, so no way to synchronize or do anything else. I de-installed Lightning and re-installed it. But no help even after restart of Thunderbird. This must be urgently taken care of as it is vital for using Thunderbird. Thanks for it!

Thanks to "testbutton", this issue is solved: Unselect "show Calendar Week" in the Calendar menu. It makes the calendars appear.

not all i perfect Rated 3 out of 5 stars

. update to 45 went ok but I now cannot accept invitations directly from the email. I keep getting "No writable calendars are configured for invitations, please check the calendar properties."

I guess this is in combination with the Provider for Google Calendar? I don't think we changed anything specific in Lightning related to writable calendars and invitations, but we are happy to help out in the support section.

Relying on it for years Rated 5 out of 5 stars

Was an early adopter during the beta-testing years where it was rather flakey and have been very happy with it for years now, especially with the google calendar add-on.

Fedora 23 just automatically updated to thunderbird 45.0 + lightning 4.7 and the calendar tab came up completely broken. Mad panic / googling. Just did a manual install of the lightning 4.7 .xpi and after a restart seems to be back to working aok.

Happy you found a solution, sorry it didn't work out without glitches!

Simply Awesome! Rated 5 out of 5 stars

very useful and must have addons. Perfectly working with Thunderbird 45.
Thanks to developers :) .

From Ecstatic to Disappointed Rated 1 out of 5 stars

I've relied on Lightning for many years, since it gave me an alternative to Outlook when added to Thunderbird, and I no longer had to parallel my email gathering and calendar maintenance between Seamonkey or the two-window Thunderbird/Sunbird combo (and still have to use Outlook for some endeavours).

With today's update of both Thunderbird and Lightning, that ease (and trust) ended, since Lightning only gives me a grid. Worse, in going back (yes, that's how important my calendar is) to the previous versions of the client and calendar (where both worked together), Lightning does nothing. It won't load. Its button has disappeared, as has its integration into Thunderbird ("settings" gives me only the client's settings, with no Lightning options).

Now I'm left wondering if my calendar database(s) are okay and still usable, should I manager to get a working version of Lightning installed. I may very well go back to paper for time management. It may be old tech, but it has proved consistent and reliable.

This is not a bug report. This is a review of the latest iteration of the extension as I've experienced it. Since I use the app for time management, there is a high lever of trust that it will be there, functional and unglitched.

That trust was broken today. (Even worse, reviews of the newest version posted here were met with admonishments that they were glitch reports. The disappointed user shouldn't be made to feel guilty for posting a bad review of something that doesn't work, based on their honest experience.)

Yeah: Really not happy.

Thanks, this is the kind of review I can understand. What I was trying to say in previous answers is that I believe this isn't at all an issue with Lightning itself, but rather with the Thunderbird update process, and also something that can easily be remedied through support. As you can see, others have posted that the update worked for them without any problems at all.

I am certain your calendar database is still intact and I am sorry the update process is such a pain for you, I am glad we only do major updates every 42 weeks now. Just imagine this kind of thing happening every 6 weeks following the Firefox cycle.

When using Thunderbird 38, make sure you are using Lightning 4.0.x, when using Thunderbird 45 make sure you are using Lightning 4.7. That's about all I can say here, I am happy to help further in the support section.

Funktioniert einwandfrei.

calendar is lost ! Rated 1 out of 5 stars

after having upgraded to TB-45, calendar and tasks are no more visible ; neither in preferences.

What is wrong in the profile, knowing that on the same computer, i have created a new profile where calendar and tasks are OK ?
Thanks !

Please check with support for this issue, or try re-installing Lightning from this site.

Dumb Thunderbird Update - Part 2 Rated 3 out of 5 stars

The developers reply to "Dumb Thunderbird Update" is, at best, not accurate as of 4-25-16. Thunderbird updated via the automated update apparently does not come with an updated version of Lightning. Nor does the lightning update from here function (it's not allowed - not signed). In order to get a copy of Lightning that functions with Thunderbird 45.0 you apparently have to download the Thunderbird installer and reinstall Thunderbird. IMHO, just plain sloppy!

Update: It is possible that today I did get confused by the similarity in appearance between the add-on pages for Firefox and Thunderbird and attempted to install Lightning in Fiirefox as a response from the developer suggested. But the bottom line still is that it appears automatic updates to Thunderbird are resulting in Lightning disappearing until one or the other is reinstalled. I'm apparently not the only one seeing this phenomenon judging from the reviews I'm seeing. Nor is this the first time Lightning has disappeared on me.

FTR: Ligtning would get a considerably better rating from me if it weren't periodically disappearing.

If you are getting a message that the Lightning update is not allowed because it isn't signed, then you are likely attempting to install Lightning into Firefox. Thunderbird does not require extension signing.

I've checked the Thunderbird update files and they contain Lightning, so it must be something else. I would love to help and fix any potential issues, but I really don't want to spark any discussion here as the reviews are not meant for support issues nor bug reports.
