All day task Noté 4 sur 5 étoiles

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 Noté 1 sur 5 étoiles

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_).

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 Noté 1 sur 5 étoiles

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 google integration

Worsening with age, indeed Noté 3 sur 5 étoiles

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! Noté 5 sur 5 étoiles

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.

Thunderbird disappears Noté 5 sur 5 étoiles

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!!

LIghtning - worse with age Noté 1 sur 5 étoiles

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! Noté 5 sur 5 étoiles

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 :)

Kubuntu 16.10 + TB 52.1.1 (64-Bit) + Lightning 5.4 No Date Time Popups Noté 4 sur 5 étoiles

All software latest versions. It all seems to work except that there are no more date time popups when entering or editing an event.

Since a few months back, the core functions of lightning have been broken for me Noté 2 sur 5 étoiles

Since a few months ago, the Calendar and Tasks menu items under view have been greyed out when I have lightning installed. As a result, I can only see my events in the sidebar view, not as part of a broader calendar. I've updated thunderbird to the latest version, disabled and re-enabled lightning, removed and reinstalled lightning, and nothing has helped. I would like to rate it higher, because for quite some time it did what I needed it to do- but lacking a functional calendar view as such means the addon isn't what I need it to be.

bug Noté 3 sur 5 étoiles

I've been using lightning for many years now. It is a very nice extension however since few versions the stability of the module is very bad.
I have several calendars but some part of calendars did not appear in thunderbird even after sync....
it is boring
I don't know why but sometimes it works fine and sometimes it bugged

Unistalled in cause of losing events and poor ergonomy Noté 1 sur 5 étoiles

I am so fed up with this module, after months of trying, I uninstall it : so bugged ! I'ts been many times I find myself in front of a "new event" event, days after having reating it, and can't remember what it was ; simply because the soft forgets the title of your event, if tou type and validate too quick. A reminder that reminds you that you have a something to do, without precision, what bitter irony !

Other bug while dragging a border to extend/reduce the length of the event : my mouse gets stuck and starts moving the whole TB window instead of the border of the event.

Focus is delayed, and forgets the first characters you type when you start typing a new title.

Events that spread the whole day, instead of occupying visually the whole column of the day, appear as a tiny little box, lost in the top, making you believe your day is free.

If you create an event, name it, and open it too fast to add a description inside, the title you typed is lost and replaced by "new event"

Ergonomy sucks : never seen much shitty hour selection tool (click on a list ordered on minuter after tthe other !!!) ; unable to type directly text in the details field, when you create the event

Why the helle, when you change by keyboard the starting hour of an event, it changes automatically the ending hour too ?

No way to change quickly the attachement of an event to any calendar : you have to open it and roll the selection box inside it

When you duplicate an event, it assigns it automatically to the first calendar of your list, instead of the calendar onf the duplicated event.

So, too much meetings failed because of the lack of safety of typing ; too much ergonomy failures, manking me too regularly angry. I uninstall this bad tool, and will, as good old times, use my calendars directly in Goolgle calendar.

Thanks for taking the time to mention all the issues, I am sorry you have been experiencing issues. I'd appreciate if you could file bugs on for each separate issue. The product is "Calendar".

Duplicated fields in Event window: Date and time Noté 3 sur 5 étoiles

Just updated Thunderbird this morning. Lightning now presents duplicated "Date" and "Time" fields for start and end of any given event. NOTE: actually, I accidentally downgraded Thunderbird to version 45.7.0, and after fixed that with the correct version 52.0.1. .

Reminders steal focus == BAD Noté 3 sur 5 étoiles

I've been using TBird+Lightning for many years now. I have approx 10 calendars and Lightning's focus stealing behaviour every time it updates the reminder pane is a real killer. Time after time I've been typing away only to find that the reminder pane is up on another monitor stealing all the keystrokes. It is really obnoxious behaviour irritating enough that I am about to give up on it. Too bad because otherwise it is a pretty good calendar program.

Hi Philipp I couldn't see any other way to respond to you other than by editing my comment. Thank you for your response!
I believe no program should steal focus unless it has been authorized to do so by the user - in other words this should be a user option at least in about:config if not in the main UI.
And yes every time the calendar server is queried to refresh calendars focus is stolen and the reminder window is refreshed - been like this as long as I can remember.

Also some people may use the reminders window the way you say but I don't see why I should need to dismiss a reminder until I am ready to? I don't want to have to keep snoozing it, I want it on the screen where I can see what I still have to get through. I only snooze something when it will be hours before I can get to it.

I understand this is annoying if it is stealing focus even though no new reminders are added and we should fix that, but please also note that the reminders in the reminder window are meant to be dismissed or snoozed when they pop up. The focus stealing is on purpose, because you also don't want to have that window be hidden at the bottom and miss a reminder.
