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.

With the new version of TB the address book has become unusable. It is not White Text on white background. I can't find any settings to reset or apply a theme or fix the colors of the text within the address book. There are many settings and themes that one could apply to the mailbox but if one can't see the address book that pretty much it useless to try to use the email.

How does one just set up the ENTIRE program to apply a theme? Or can we get a working White and Dark themes that address all Text and All backgrounds to make them legible so there are at least useful. TB has become very frustrating. Sorry to rant but before the big changes to use native Darkmode it was really good email client but like so many that try to embrace the darkmode trend (which isn't a bad idea) they are falling short of addressing the entire product.

Any help to address the color issues in the address book would be greatly appreciated.

Had to reinstall, so starting over. When I look at the Junk log, there are tons of messages listed that are not junk. How do I rescue them? and how do I make sure they are not treated as junk in the future?

Hello, I have three free.fr email addresses in Thunderbird under Windows 10. Several of my folders and subfolders, along with the corresponding messages, have disappeared. I can find their traces in my profile in the Mail folders. How can I restore them? Thank you.

Bonjour j'ai 3 adresses mail de free.fr sur Thunderbird sous Windows 10 Plusieurs de mes dossiers et sous dossiers et les messages correspondants ont disparu. Je retrouve leur trace retrouve dans le profile dans les dossiers Mails. Comment faire pour les restaurer merci

I'm getting junk mail that uses my wife name as the sender. My wife died a year ago and I do not like seeing her name being used this way. Basically, the email (fake billing) has: her name as the sender my email address real sender address (junk/spam name from gmail).

I need to have any email as she being the sender to automatically go to junk and trash.

Please, tell me how I can do this. I'm getting up there in years, so any help and a "how-to do it", I would really appreciate it very much.

I was not able to "see" any way within Thunderbird on how I can do it. BTW- the version of Thunderbird is: 128.9.1esr (64-bit) and my OS is Ubuntu 24.10

Thank you for your time.

I have been using Thunderbird since its inception. I am currently on 137.0.1 using W10 Pro with all updates as well as another DELL machine running W11 Pro with latest updates. Suddenly, on BOTH machines, the calendar popup notifications have ceased to appear. I am able to perform all other calendar functions ie: new events, edit, etc. Weird to say the least. No changes have been made to the event notifications settings. Wassup?

I thought I'd subscribe to an RSS feed using Thunderbird. I got to the add feed window but it is too big for the screen and I can't scroll down to click the enter button. Nothing I do enables it to resize, including in settings and about:config. I'm on the latest linux version.

I recently switched to a new desktop computer running windows 11.

I installed Thunderbird and copied the profile folder accross from my old PC, which was running Windows 10.

Everything appeared as expected when opeing up thunderbird on the new pc - emails, subscribed calendars etc. I can access all calendars and add / modify events etc. I can see that the Google calendars are syncing OK as events added throught Thunderbird show up on my phone when accessing the calendar directly. Reminders also appear on my phone for events added through Thunderbird on my PC, but no reminder window anywhere on my Windows desktop.

I'm wondering if this is a Thunderbird issue or if it's Windows 11 blocking the notifications.

Any help much appreciated

I've been running T-Bird v.38.8.0 on a Windows 7 computer for years. I have the server settings for my account to "Empty Trash on Exit", and it's been doing that flawlessly for years. Recently (past few days), it has failed to empty the Trash folder on shutdown. The server settings have not changed (box is still checked to empty the trash on exit). If anyone has experienced this issue, can you help me fix the problem? I would very much appeciate your help. Thank you.

When I set an event on my calendar I set a reminder for 2 days. I would always get a popup when using e-mail or calendar functions. I have a new computer with the latest version and I do not get reminders where before the new computer it worked fine. I am at a loss.

I've been using Thunderbird and its Calendar for MANY years very happily :-) My old main computer is a w7 Lap and the Thunderbird Calendar in that version has the option to set up a Reminder Notification via Email. And it still works with no problem! I just was given a used Laptop computer that I did a clean install of w11 on, and installed Thunderbird and setup the Thunderbird Calendar to my Google Calendar with NO problems! EXCEPT: I just created a New Event and a Reminder for it, and to my chagrin, there is NO option to be notified by Email anymore !!! grrrrrr  :-( Please, I beg the developers to reinstate that option ! I use that for every event that I create! eg I take MEDS and when I get the email reminder, I can delete the Email reminder to show myself that I've taken that med at that time !!!! Please advise ! THANK YOU

Since installing Thunderbird contacts are disappearing from my iphone. They've also been deleted from gmail and icloud. How do I stop thunderbird from deleting my contacts?

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.
