In reply messages, Thunderbird (macos 128.10) adds an indent to the subject line in the pane view. When the thread is very long the subject disappears because of the successive indents. Is there a way to remove these indents by default? Thanks in advance. Gérald

Hi,

Someone sends me a calendar appointment for 11th of May at 16:30-18:30 and another at 18:30:20:30. I accept these appointments. In my calendar, they correctly display at these times.

When I close and re-open Thunderbird, the first appointment is now scheduled for 12th of May, but the second is fine. When I close and re-open Thunderbird again, the second appointment is now scheduled for 12th of May as well.

The times are completely different too.

I'm using Thunderbird 138 from the Arch Linux repositories but I've also tried the Flatpak package to no avail. I've tried setting my Timezone manually and using my System timezone to no avail.

GNOME Calendar, which is also synced to my Caldav server, displays the appointments at the correct day and time. The web interface for my mail server also displays correctly.

It's only Thunderbird that screws it up time and time again.

This has been going on for years and it is driving me insane. I can't use my calendar with Thunderbird because I keep thinking my appointments are at the wrong time!

Send help.

I want to save a PDF from Thunderbird under a slightly different name from what is already existing within the directory. This would save me from repeatedly typing filenames.

For example my directory already contains "version1.pdf". I want to save an attached file as "version2.pdf". To do this I first search for "version" and highlight the file. Then I want to just change the 1 to a 2.

But the moment I highlight "version1.pdf" in the file list, the REPLACE button is greyed out. Is this intended behaviour?

TB 128.9.1esr, Ubuntu 25.04

Is there a way to disable Thunderbird’s ability to open email attachments (image attachments currently)? We’re no stranger to message spam, or how message remote content can be abused, but images can still display fraudulent content. I’m hoping the images don’t contain any other surprises. Thank you for your time.

Some months ago, my email account with Cox.net (pop.east.cox.net) was transferred to Yahoo (imap.mail.yahoo.com). I was able to keep my existing email address ([email]@cox.net) but in the process, all my pop email at Cox disappeared from Thunderbird. I haven't had time to address this till now.

I have located all the "lost" email under the Thunderbird folder in the C:/Users subfolder. All the mail can be found under C:\Users\Dinger PC\AppData\Roaming\Thunderbird\Profiles\ditb93lv.default\Mail. All the mail is in a subfolder called pop.east.cox.net and is either individual files (.msf) or located in separate folders with .sbd extension.

I tried moving the .sbd folders over to the currently active imap.mail.yahoo.com but after restarting Thunderbird several times, they still don't show up. Maybe because they are not on the yahoo server but just on my computer.

There has to be a way to recover these emails and get them into Thunderbird. Can you help?

I'm unable to send any email with Thunderbird on my new Windows 11 laptop. I've used Thunderbird for years and years on the old Windows 10 one, but it won't send anything with the new one. The version info it gives is "128.5.1esr (64-bit)". Whenever I try to send an email message, it waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username [email removed]@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings. Authentication method looks fine, but the password (Settings->Saved Passwords) is empty (?? But I entered the password when I started Thunderbird and asked it to save it).

I'm having trouble with Thunderbird on my new Windows 11 laptop. I've used Thunderbird for years and years on the old Windows 10 one, but can't get it to work right on the new one. The version info it gives is "128.4.4esr (64-bit)"

Specifically two problems. (1) Every time it starts it asks for my yahoo server's password. Even though I check the box asking it to remember it, it doesn't. Under Settings->Privacy&Security (under Passwords)->Saved Passwords, the list is empty. (2) Second problem (may be same as first, but in a different form) Whenever I try to send an email message, it fails. It waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username [email removed]@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings (which I have done, and all looks OK).

Thanks Bill Marshall, [email removed]@verizon.net

When setting up Thunderbird, I did not see the radio tick box for removing mail from the server. What will happen now that I have removed about 10000 pieces of email from my local account on my computer's hard drive?

I have more questions, but would rather ask one at a time.

I have an older computer and email ([email removed]@hotmail.com) works OK on it. I also have a newer computer and its email stops at 9 Sept. How do I get newer emails on my newer computer?

This morning, my Thunderbird email stopped working although it was working fine a few hours earlier. The following is the error message: "Sending of password for user lepitzki@telusplanet.net did not succeed. Mail server pop.gmail.com responded: [AUTH] Username and password not accepted." After trying to find a solution at telus.com, my internet provider, I finally spoke to a real person (after nearly an hour on hold) who informed me that the recent google gmail update now prohibits third party email services, such as Outlook or Thunderbird, from connecting to Telus gmail email. And, that there is no work around or solution and that a supervisor could not offer anything further. I have been using Thunderbird for telus email for decades, I weathered the storm when Telus email moved to using the gmail platform, and I have many, many folders and subfolders. The Thunderbird third party platform allows permanent offline archiving of emails, which I require for my work. Is Thunderbird aware of this major issue caused by an update via Google? Will there be a Thunderbird solution or workaround? Thanks for your consideration. Dr. Dwayne Lepitzki, Banff, Alberta, Canada

I've followed Thunderbird setup according to "Automatic Conversion of Google mail accounts to OAuth 2.0 Authentication" (https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20) The failure is described in my initial post below:

Mozilla Support - Signin, and use of Thunderbird https://support.mozilla.org/en-US/questions/1484529#answer-1729438

LarryGad post (Reply to Ashley LambertonQuestion owner): I get the same screenshot Ashley posted above. But...clicking Allow doesn't download my Gmail messages. And clicking the link, Account Permissions, just produces a blank window. An idiosyncrasy is I'm the domain administrator for a "Free Legacy Edition of G Suite for personal use".

This paragraph may not be relevant to the above issue. I did stumble across the Account settings link (https://myaccount.google.com/general-light?pli=1) which contains the line: 'Connected accounts View and manage your accounts from other services' Clicking the 'View ...' link goes to https://profiles.google.com/connectedaccounts and displays the message: "404. That’s an error. The requested URL was not found on this server. That’s all we know." Highlighting the 'View ...' link shows https://profiles.google.com/connectedaccounts?authuser=0

Thanks in advance.

Can you please help me in composing a message, specifically, changing the line spacing? As I type, I may choose a different font which may require me to choose a different line spacing, either bigger or smaller for readability and aesthetic purposes. Thanks!

Guys, I am on TB 128.6.0esr (64-bit) and I am using TB since Netscape era (25 years now).

Since last update, when I try to forward an email in my Sent box, it produces a blank window with only the subject filled-in. No content, no attachments.

I tried Repair to the box but it's still the same.

The problem happens with all recent mails but not with all older mails. For example, some older mails, sent e.g. one year ago, or more, when clicking forward, behave as expected, with content and attachments. Other ones, however, do not work and open as blank windows, as I explained.

It works always with "Forward as Attachment", but this is NOT what I want.

Has anyone faced this problem? Do you have any suggestions? Should I file a bug?

Please advise.

Thanks, Nick

WHY is reading my email SOOOOOO EXASPERITING????

Headers are HUGE but the main thing, the text body, can only be read one line at a time!

You really do not seem to have the concept of what your users are going through!

There is no way to fix that on our end!

Smaller text size would just make what we need to see and read too small to read! Why not a separate butten to show all they jumplk loodinge header test?

This really miserable to work with. Or try to work with it. The eamil headers would still take over and hide what we need. You think WE are worried about fixing spam that way? It's taken over by the time you try to see what is going on!

WHY IN YOUR CRUEL HEARTS DO YOU NOT ALLOW US TO GO BACK TO WHAT VERSIONS DID WORK WHEN PEOPLE LOVED THUNDERBIRD?

Thunderbird 138.0 x64 will NOT check folders for emails/messages OR deleted emails/messages (other than the INBOX folders) unless I FORCE it to by clicking through EACH folder, INDIVIDUALLY. And sometimes even THAT fails to see or note existing emails/messages sent previously OR saved for future reference. Yet I can WATCH it display processes as they work through various folders at the bottom of the "Home" page. Won't show any "changes of or to", DRAFTS, SENT, TRASH or any of my added folders such as ARCHIVE or SAVED EMAILS although my "email providers" (Spectrum, Gmail) show every email/message available in every folder.

What's actually going on? I don't understand and I ask for help here, please.

Oh, and Thunderbird MOBILE is even worse. If it's NOT at it's "polling time" (every 15 minutes or whatever) it doesn't get new messages unless or until I go to the "HOME" page and tap the "Check Now" (rotating arrow) Icon. Any help here?

Thanks for any help, other than "take a long walk off a short pier".

duplicate of /questions/1509913 thread in Thunderbird for Android section

I miss one thing from the regular Android mail app. The possibilty to set a time periode for mail checking. Like check each hour from 09:00 to 23:00. (to make it NOT check for mail at night)

How do I turn on the format text toolbar/menu in Thunderbird 128.9.1 running on Ubuntu 24? When I compose a new message, this menu doesn't seem to be available. I've tried using automatic and HTML only in Settings -> Composition -> sending format. In View -> Toolbars I no longer have a format text option (as I did with TB running on Win10)

Thanks.
