I am running Thunderbird 141 on Windows 11. When I open the task tab, it says: "Please select a calendar that supports tasks". I have tasks on two gmail accounts. But it wont let me select either of them (or my other account).

How can I set the calendar to completely show on the screen - currently in Full Screen mode half of Sunday is off the screen, including the settings icon next to Day/Week/Multiweek/Month. My monitor is a 19" diagonal 4:3 - not a widescreen 16:9. For what it's worth the mail screen displays fine

Thanks, Marc

Ich bekomme ständig folgende Aufforderung: Authentifizierung erforderlich - Mozilla Thunderbird https://spica.t-online.de verlangt einen Benutzernamen und ein Passwort.

When moving a task from "meine Aufgaben" (my tasks) to another Gmail calendar tasklist ("AI"), a ghost entry, which cannot be completed or deleted, remains in the old Thunderbird tasklist "meine Aufgaben". Thus I have many tasks twice in different Thunderbird-calendars, but only once in Gmail.

I have TB 140.3. I;m trying to use the task function. At the bottom of the task column it says "select a writable calendar". Clicking it doesn't do anything. It won't let me set up a task. What do I do? Surprisingly there's no mention of tasks that I can find anywhere in any settings page.

(None of the topics provided when creating the question seems to "best describe" this question. So I chose one at random.)

When I create a new task, I can choose a due date. But it seems that when choosing a due date, it forces me to also choose a due time. Is it possible to add a task with a due date but no due time? Maybe something akin to the "all day event" for calendar events?

This answer says to "choose the option 'All Day Event'", but I don't have this option when creating a task (see attached screenshot).

My workaround is to choose an arbitrary time. While this works somewhat, it's unsatisfactory.

Thanks for any help.

Request Assistance: 1) I can no longer find the software version of thunderbird when I start up the software. Seems like I need to determine that first.

2) The calender pane that used to be on the right side of the screen is no longer there and I can't figure out how to restore that pane.

Thanks, Steve Rothert

Some of my calendar reminders are not appearing. At least one in particular is still showing. This is a daily reminder. Other reminders whether for a set period or just a one off do not appear.

I am using Version 140.1 on Firefox.

Hi there,

I have configured my Google Calendars in Lightning, using the Provider for Google extension. But my primary mail account is not the google mail account.

When receiving invites I get the message that no 'writable' calendar is configured. I read that you should be able to associate another mail address to an Calendar but apparently this option is not available using the Provider for Google configuration.

Any suggestions?

I have one question and a suggestion.

My question is why doesn't the alarm I set in Lightning work unless Thunderbird is open?

My suggestion is a calendar for Windows and an identical calendar for Android that sync so that I can avoid telling Google all about my life. I've worked hard to avoid Google. I use Firefox as my browser. I use DuckDuckGo as my search engine. I don't use a GMail address. I use Thunderbird to send my messages from my PC. I use an alternative navigation program on my phone and I turn off my GPS when I'm not using it. I use Dragon to talk to my phone when I'm driving instead of using Google Assistant. I use simple calendar, simple file and simple gallery instead of the Google alternatives. And I "sync" my calendars by entering the same information manually into the calendar on my phone and the calendar on my PC (Efficient Calendar Free).

But, boy, it would be sweet if I could find a non-Google calendar program that would sync across my devices. That would really be sweet.

Keep up the great work. You're not only making good products, you're protecting what little is left of our privacy, and I, for one, appreciate that.

I am trying to link to a calendar hosted on www.onlinescoutmanager.co.uk. That application supplies a URL for me to paste in to a calendar application. I successfully create the new calendar in Thunderbird (i.e. I see a message saying the calendar has been created) but no events appear. The new calendar is shown greyed-out in the Calendar List. Opening its properties I can put a tick in to 'Switch this calendar on' but on clicking OK the calendar in the list appears properly for about a second before it is greyed out again. The error console shows the following: While creating services from category 'profile-after-change', could not create service for entry 'calendar-backend-loader', contract ID 'service,@mozilla.org/calendar/backend-loader;1' Expression Search: init... Use of Mutation Events is deprecated. Use MutationObserver instead.

Two days ago, my Google calendar tab disappeared in Thunderbird and I don't know if it is possible to get it back. I manage all events and appointments from Thunderbird so am really missing it. How can I get it back.

Hi,

Yes, there is an article how to do this. But that does not work. Doing it says: - I have installed the appropriate extension - I select File =>new => Calendar => from network - I select Google calendar - I type the requested email address

Here it stops! I get a message (translated from Dutch) "You browser does not allow javascript. Please turn on javascript" The window is not from my browsers, but from Thunderbird. Kidding? How to allow javascript in Thunderburd

Win 10. TB 60.3.1. With the 60 update all events (past and future) in Calendar disappeared.

Tried uninstalling Lightning in addons manager | extensions and then resetting (in ConfigEditor): extensions.InstalledDistroAddon.{e2fda1a4-762b-4020-b5ad-a41df1933103} and then restarting but no joy... historic calendar entries do not reappear.

Hello!

I've just installed Thunderbird, specifically with the intention of using its Calendar features. I've imported several calendars from my Google account and am keeping everything synchronized bidirectionally with the Provider add-on.

My case is as follows; I have multiple events that are currently in calendar X, but I wish to move them to calendar Y. I was hoping it would have been possible to batch edit selected events (or at least have the ability to move the selected events to another calendar). But to my disappointment, there doesn't appear to be such an option (yet).

I've done my fair share of looking up this issue but to no avail. So I can't help but wonder, is there truly no way to easily do this other than editing the events one by one?

Any help/tips are appreciated, thanks in advance!

The topic for "Calendar updates issues with Thunderbird" (https://support.mozilla.org/en-US/kb/calendar-updates-issues-thunderbird) is well described, but does not work for me (Ubuntu 18.04.01 LTS, Thunderbird 60.2.1, Lightning 5.4) as I don't see a config editor? Is there a shell option to start TB's config editor? At least I could not find one via thunderbird -h. Currently Lightning is deactivated due to incompatibility. Many thanks already reading and hopefully help. Regards, Christian

Attempting to restore calendar to Thunderbird 60.2.1 running in WIN 7 Pro. The "available" Lightning add-on is incompatible with this version of TB. However I know that Lightning 6.2.2.1 is running happily in another otherwise identical installation! How do I get the file (.xpi ?) to install Lightning 6.2.2.1 ? (I see solutions for Linux folk in this quandary, but nothing for Windows?)
