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?)

My calendar has disappeared. I have years of important dates that are lost. . . say it ain't so, Mozilla! WTF. My "add-ons" show nothing installed. Are you kidding me? They broke Thunderbird?

Sorry if this is in the wrong place. Did not seem to be an obvious one for my question.

I go tired of the Outlook web client always trying to us AI to assist me. Installed Thunderbird ver 128.6.1 esr on a Ubuntu 24.04 system running Cinnamon desktop. All components are up-to-date (or should be as auto-update is on). System details at end of message.

Screens for mail and tasks are rock solid. The calendar jitters up and down rapidly small amounts. Not the entire page. Just the part where the calendar is displayed. Makes things a tad blurry and is tiring to look at.

Any ideas on how to resolve?

TIA

I'm trying to connect Thunderbird to my Mailcow server SOGo Calendar, but it does not work. It's not a typical problem, because SOGo generates for me two CalDAV links to connect this: 1. Link for signed in users (with RW access). 2. Public access link (with RO access). I want to manage my own calendar, so I need first case. Then I go to "Creating new calendar" window in thunderbird, enter public access link just to check, and calendar is connected! But it's not all. Then I go back and paste link number 1, also providing credentials info (I have tried a lot of variants, also "test@example.com:password", "test@example.com" and so on) and after pressing "Next" button I get a typical connect error like "Could not find your server, please check entered info".

I have done a lot of tests and checks, and this is a strange details, that I caught and I think it is a Thunderbird bug (I might be not right)... On my nginx reverse proxy I see such log when Thunderbird is trying to connect by my link with RW access: "my-ip-address - - [04/Jun/2025:23:39:51 +0300] "mail.example.com" "PROPFIND /SOGo/dav/test@example.com/Calendar/personal/ HTTP/1.1" 404 146 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:139.0) Gecko/20100101 Thunderbird/139.0.1" "-"". As you can see, my server returned 404 error.

You can think, that problem is on my side and my server is wrong, but please check next nginx log: "my-ip-address - test@example.com [04/Jun/2025:23:38:43 +0300] "mail.example.com" "PROPFIND /SOGo/dav/test@example.com/Calendar/personal/ HTTP/1.1" 207 125 "-" "curl/7.88.1" "-"". It is succeeded, but this is after my manual curl command like "curl -v -X PROPFIND "https://mail.example.com/SOGo/dav/test@example.com/Calendar/personal/"". You can compare two strings from nginx log that I provided and you will see the only difference is second dash in first log instead string "test@example.com" in second log. That piece of log string contains nginx variable $remote_user, and that means that Thunderbird while trying to connect my server calendar do not provide auth credentials and send request without any user that I enter to corresponding field before connect attempt.

P.S. You can ask me why do I test connection just by PROPFIND request type, because Thunderbird tries some different ways to connect too. And I will ask that: 1) Only one succeeded request, by what Thunderbird connects to my public calendar is with type PROPFIND (as I can see in nginx reverse proxy logs); 2) Other attempting ways to connect falls with same error and also do not contain any user, as I explained before.

Please give me feedback about way how I can fix that and thank you very much for your support!

import calender not working on new laptop windows 11. I have all my emails but no events show. i tried to import from your app but got an error message, I copied the calender export to a key but I still get the error message and the new calender has no events.

The time shown in the Date column for TB is 2 hrs earlier than the actual time. The TB error console also displays the wrong time.

TB 128.6.0esr on freebsd-13.4-RELEASE-p5

System time is set to and displays as MDT (US Mountain/Denver) $ date Fri Apr 18 12:29:52 MDT 2025

TB error console: Date() "Fri Apr 18 2025 10:31:04 GMT-0800 (GMT-08:00)"

about:config timezone settings: calendar.timezone.local MST calendar.timezone.recent [] calendar.timezone.useSystemTimezone true mailnews.sender.date_senders_timezone false

Mail headers show proper time in mail file: Received: from mail-yb1-f187.google.com (mail-yb1-f187.google.com [209.85.219.187]) ... for <xxx>; Fri, 18 Apr 2025 11:55:40 -0600 (MDT) Received: by mail-yb1-f187.google.com with SMTP id 3f1490d57ef6-e5740c858besf2902470276.2 ... for <xxx>; Fri, 18 Apr 2025 10:55:39 -0700 (PDT)

And display properly in the TB headers display: Date Fri, 18 Apr 2025 11:55:29 -0600

Yet TB displays 2 hrs earlier in the Date column: 09:55

How to correct? I had set the Calendar timezone manually, but it is now set as above. I tried deleting calendar.timezone.local but it is rewritten when TB exits.

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).

Hi, my Thunderbird calendar reminders are coming up 4 hours after the meeting.

Running Kubuntu. System locale/timezone OK, TBird set to use system time (though manually making it the same didn't help). HW Clock matches system time. Pacific/Auckland.

Tried exporting all my appointments and re-importing them - no change.

Steps: 1. Setup Thunderbird with a CalDAV calendar (in my case I am using Baikal as the back-end). 2. Add (and modify) a bunch of tasks and calendar events to that CalDAV calendar, using Thunderbird and any external CalDAV tool (in my case I am using Tasks.org on my phone).

Expected behavior: The tasks and calendar events would seemlessly sync between Thunderbird and Tasks.org.

Bug:

• Tasks and calendar events added on the Tasks.org do not end up in Thunderbird.
• Tasks and calendar events added on Thunderbird, however, do end up on Tasks.org as expected.
• Tasks and calendar events modified on Tasks.org are not be synchronized to Thunderbird.
• If a modified, not synced tasks or calendar event would be modified in Thunderbird, the latter prompts ```This item has recently been changed on the server. Submitting your changes will overwrite the changes made on the server.```.
• Pressing the button "Reload all calendars and synchronize changes" has no effect.
• Toggling online and offline mode has no effect.

I have run into a calendar notification bug when Thunderbird is not executing. This started about a month ago and may be due to changes in the 140esr release (I was on 128esr previously).

Suppose I set an appointment for tomorrow at 9pm and ask the calendar to notify me a day in advance. If Thunderbird is executing at 9pm on day before, this works fine. If Thunderbird is not active, the notification is never made when I open Thunderbird after 9 pm on the day before the appointment.

This problem also occurs if I Snooze the notification and do not have Thunderbird running when the snooze period is completed. If does work if Thunderbird is open at the time of Snooze completion.

I have tested this on two different computers, a desktop and notebook, both running Windows 10. Currently running Thunderbird 140.2.0esr.

I have missed two appointments when Thunderbird calendar did not warn me about them.

(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.

I have 3 Google calendars added to Thunderbird. After every startup I get a popup with the Google authorization page for every calender asking me to authorize access. I already tried removing all Calendars, cleaning the cache, resetting all calendar/google related settings in the config editor and readding teh calendars.

Is there a way to avoid the reauthorizations after each startup and have Thunderbird access permanently authorized?

There are no add-ons except Owl for Exchange (needed for my work outlook account) and Compact Headers.

Thunderbird is version 128.6.1esr on Ubuntu.

After the last update of Thunderbird the calendar will not hold the sync with Outlook calendar. I tried resetting the sync link without success.TB will flash the events from Outlook when I click the "Enable" button but not hold them. Is there a solution?

hi, I'm using the same TB Calendar setup for a while (3 years), in February 2024, calendar sync became erratic with showing under TB Calendar a warning : your agenda is temporarily unavailable, some events did not sync . but for the last couple of days, I'm unable to sync any events from my yahoo calendar towards TB calendar. the tbsync shows OK, reports no errors in log. could you help please , this is quite urgent matter for me. Thanks lot Phil

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 updated from TB 115 to 116. I had to re-enter email and calendar (to Google) connection info. Calendar does not display. Email and Contacts seem alright. Is Provider still needed?

Thunderbird version 115.12.2

How can we keep the month calendar visible in the Today Pane?

The option mentioned here seems gone: https://support.mozilla.org/en-US/questions/1420812

I successfully subscribed to an online .ics file but I found the resulting calendar entries inadequate and I want to unsubscribe but I can't figure out how to do that. I've tried searching for instructions but haven't found any.
