All was well until about six months ago. When I try to connect to my provider TB won't connect. BUT. At other times it will connect then every few minutes will try to connect again - then again .... I get this message "Connection to the server mail.comcast.net timed out". Then I get this message each time it fails "Login to server mail.comcast.net with username 170834000 failed". It keeps asking me to input my password even though everything is working appropriately. Then at other times it says it doesn't connect but it has connected and it still continues to ask me for a password.

I have uninstalled TB and reinstalled it thinking that would fix it - it didn't. I have changed my password - again to no avail. I let TB choose where to put things and configure each item appropriately. I don't try to get in the way of what works.

Comcast is apparently getting out of the email business and asking everyone to move over to their chosen substitute (Yahoo.mail) and I have not chosen to migrate at this point. Maybe that's the problem. This is the message I get each time I log into Comcast.net:

"A better email experience is now available for you

You're invited to upgrade your email account to Yahoo Mail, so you can enjoy a more user-friendly experience. Your email address, messages, folders, and contacts will not change.

With Yahoo Mail, you'll enjoy enhanced security, a built-in calendar that's easy to use, AI-powered inbox organization, and a top-rated mobile app for easy access on the go."

I am not aware of any changes in the settings from before when it was working well and now when it seems to be erratic.

I am not terribly computer savvy, but I'm usually able to trouble shoot and fix the issues that confront me. This time I'm out of my league! I need help.

Thank you for helping me.

Environment:

• Thunderbird 153.0.2 (aarch64)
• MacBook Air, M4, Tahoe 26.5.1

When I try to create or rename an Inbox subfolder in Thunderbird it all seems’’ to work (no error message), but after pressing “Rename” or Create” nothing happens.

Thought I found a workaround: Created a “Temporary” subfolder in “Local Folders” and “moved it" to the Inbox. And it showed up there. (But it was still in the “Local Folders”!). Tried moving a (Spam) email into the Temporary folder under the Local Folders, that worked. Tried moving a (Spam) email into the Temporary folder under the Inbox—it just disappeared! It was no longer in the Spam folder, but did not end up in (either) Temporary folder.

The default font I have been using in replying to messages used to be in the same as what was designated in the Composition settings. Now, with the EnhancedReplyHeaders extension, the default font is always "Variable Width," no matter what I do with the Composition settings. What do I need to do, to have the default Reply font be the same as that specified in the Composition settings? Thanks,

Host OS Failure Subject: App Freeze/Crash on Log Export – System Logcat Daemon Failure (MT6765 Platform) Device Info: MediaTek MT6765 | Android 13+ (Based on OnBackInvokedCallback logs) Package: net.thunderbird.android (com.fsck.k9)

Description When attempting to debug synchronization issues in Thunderbird for Android, the application freezes or crashes immediately upon tapping Export logs. Real-time log monitoring reveals that this is not an internal application crash, but a cascading failure triggered when Thunderbird invokes the native Android dumpstate framework on a device with severe system partition corruption. Steps to Reproduce

  1. Navigate to Settings > General settings > Debugging.
  2. Toggle on Enable debug logging and replicate the primary mail issue.
  3. Return to the Debugging menu and tap Export logs.

Expected Behavior The app packages local IMAP/POP3 commands and synchronization records into an exportable text file.

Actual Behavior

The app freezes. The underlying Android logging engine (logd) is completely dead, preventing the file generation tool from completing its routine. Diagnostic Log Excerpts The system-wide dumpstate utility explicitly fails to capture data because the device's logging directories are missing or corrupted:

logcat: Logcat read failure: No such file or directory

command 'logcat -L -b all...' failed: exit code 1

Furthermore, critical Hardware Abstraction Layers (HALs) return null pointers, suffocating UI threads when input fields are called:

Warning: Skipping "android.frameworks.displayservice... (null) 08-04 19:19:37.807 17942 17942 I InputMethodManager: invalidateInput

Developer Note

This issue is entirely environmental and not a flaw in the Thunderbird application codebase. Thunderbird successfully renders its interface (MessageHomeActivity), but when it commands the OS to compile diagnostic logs, the host device's broken firmware crashes the calling process.

when I try and add my microsoft outlook account, it redirects to a webpage, which after saying yes a few times with an already signed in session, redirects to localhost 44645. localhost 44645 notably does not seemingly direct to anything, and thunderbird does not change. clicking "continue" re opens the microsoft webpage How should i connect my outlook account? system details; ``` OS: Linux Mint 22.3 x86_64 Host: ThinkPad L14 Gen 2a Kernel: 6.14.0-37-generic Uptime: 7 hours, 40 mins Packages: 2177 (dpkg) Shell: bash 5.2.21 Resolution: 1920x1080 DE: Cinnamon 6.6.4 WM: Mutter (Muffin) WM Theme: Mint-Y-Dark-Aqua (Mint-Y) Theme: Mint-Y-Aqua [GTK2/3] Icons: Mint-Y-Sand [GTK2/3] Terminal: gnome-terminal CPU: AMD Ryzen 7 PRO 5850U with Radeon Graphics (16) @ 4.508GHz GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series Memory: 14803MiB ```

For a few days now I have not been able to print pdf files from within Thunderbird.

I am using 154.0b2 (64-bit) Beta version, but had the same problem with the previous version.

If I try and print the pdf it creates the file but the file is blank. This happens when printing to a physical printer or printing to PDF on the computer. The file is created but no content can be seen.

Workaround is to download the PDF and then print it from another app but it is annoying and did not do this previously.

Printing email content from Thunderbird works fine, to physical printers or to PDF files.

Any help would be greatly appreciated.

Some of my emails have had the original correspondent's name changed to random one. The email contains the original information. Example: AJ Ket... changed to Kaiser. Please assist. Thank you.

My name is Barrie Johnson. I have been a Mozilla Thunderbird user for my e-mail services for many years. In the past couple of days I have been getting messages from Google telling me that my e-mail provider - i.e. Mozilla Thunderbird - will not allow Google to access it, with the result that I cannot get to a current version of my Inbox and there is no trace of my calendar details. Can you please help me?

Hi, I use gmail and yahoo as my onlline emails. Gmail is primary and Yahoo is secondary. I'm frequently prompted to login to Yahoo. (via pop up) New to me. I reimaged my laptop recently. Did I forget something either w/in TB or Windows? I;ve relooked at all my szettinngs. Nothibng seems amiss. Thanks for your help!

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!

I'm trying to resolve password issues. I fear that I might lose access in T-bird as I have through my browser.

T-Bird presently works to receive e-mail at two addresses: [redacted]@pacbell.net and at [redacted]@pacbell.net. It won't let me send email from [redacted]@pacbell.net.

None of my "they did work in the past" passwords allow me to log in with yahoo or AT&T

I want to use the same p- words with t-bird and yahoo and AT&T

Hi!

I have configured a EWS email account that requires manual configuration (I need to pass the override Office365 settings with application ID, tenand ID,...). When I select manual config I can configure the EWS server settings OK and the receiving part works OK. The problem is the outgoing server is not created OK (it is imap with password setup). I need to use the same EWS to send the email, imap is not allowed in the account. And I cannot configure the account to use EWS as the outgoing server. The outgoing server cannot be EWS and I need to setup one. So I'm in a loop.

For what I have read, thunderbird can send the email using EWS (https://support.mozilla.org/en-US/kb/thunderbird-and-exchange), but my feeling is that using manual setup (which I need to do to configure this account) breaks something internally and the outgoing is separated from the EWS receiving part. And I cannot configure back to use the internal EWS configuration in the receiving server part.

Can I do something to send emails using the same EWS configuration? What does the automatic setup to use the EWS configuration? Is there any bug for this situation?

Thanks in advance!

After updating to 153.0.1esr(aarch64). the SEND button has disappeared. There's no way to send an email. (I can receive emails.) I am a Mac mini M2 Pro. OS 26.4.1

I cannot find a link to download a previous release of Thuderbird, which was working fine until this update.

Thunderbird just updated and the next time I opened it all of the folders I created and the emails I'm storing within them are missing. I found my profile as directed. I'm not sure if I have a backup of it. I've included the screenshot as you ask for. I know that those folders and emails are there as I was playing around with the the 3 lines > View and when I moved between the different choices I saw my folders/emails are all in there.

Any assistance you can provide is appreciated!

How can i get new messages in a thread to move the thread to the top? (I have descending order selected) I miss new incoming replies when they sorted weeks or months ago by the original email date.
