I have been using Thunderbird for years and am on version 152.0.1

I also regularly use the Mail Merge add-on and this has worked great. However, just come to use it and it has put 80 messages into my Outbox but I cannot get them to send!

I hit the "Send Unsent Messages" and nothing happens.

Very frustrating and would be very happy if someone can help identify the problem!

I am using Linux Mint Cinnamon 21.3 and Thunderbird POP3 email. I have 10 email accounts.

What I have noticed is the Thunderbird 128 series startup email check and/or "get all messages" is quite slow compared to previous versions.

Thunderbird 102.15.1 took only 4 seconds to check 10 email accounts, Thunderbird 115.18.0 took 5 seconds, but Thunderbird 128 and 136 series takes 15 seconds. All of these have used the same user profiles.

There is no antivirus software active. All messages are deleted from all accounts. No messages to download and checking for messages is still slow.

I have tried the Betterbird 128 series, a fork of Thunderbird, and it too behaves the same. Betterbird 115 series work fine, just like the Thunderbird 115 series.

Is this slowness in the 128 and 136 series by design?

I am running Thunderbird on a new Windows 11 laptop. When I download new messages and try and open them my laptop locks up. Anyone else have this problem? Thanks Dave

I am running Thunderbird 140.13.0esr (64-bit) in Windows 11 25H2. I received an e-mail message that has a JPEG attachment. When I open the attachment, the image is opened with the MS Photo app. But in that app I cannot rotate the image. If I save the attachment on my disk and then open it with the MS Photo app, I am able to rotate the image. I am wondering why the instance of the Photo app invoked by Thunderbird does not allow rotation. Note that in the -Thunderbird uploaded image, the rotate icon at the top left is greyed out (and not available). Thanks.

I have not being able to add this 4 account to thunderbird: hotmail.co.uk/ live.co.uk/btinternet.com/gmail.com. I keep getting error either cannot connect to server or username and password wrong. I have managed to add two accounts successfully. I don't quiet understand what is happening with this new 153.0.1 version. I has it working before I had to reinstall windows 11 PRO. Could you help me please! Thank you! Best regards, Jairo Goncalves

I have a rather intriguing issue with the message editor which isn't a problem but puzzles me.

I monitor a number of email accounts. When compiling a message using one particular sending account the line spacing in the editor is reduced, as in the second attached image. If I use any of the other accounts it is correct, as in the first image . In each case the line spacing of the message that is actually sent is correct.

It's obviously not a big issue, but I'm struggling to understand how the editor can change depending on the sender account. Any ideas?

I apologize for the subject line, but there is no better way to describe the problem....

I've been using Thunderbird for a few months now and it has mostly worked well. Then this afternoon I was reading my mail in the Unified Inbox and I noticed something very odd. I had a number of emails showing in the header list with the same "From" and various subject lines. On the face of it, that wouldn't describe any weird behavior except that I noticed the subject lines absolutely didn't match the "From" information.

As I would go to read these emails, the email itself would be correct in the preview pane -- including showing the correct sender name and email -- but the "From" information in the header list pane would still be wrong.

I'm sorry that I can't post a screenshot to make this more clear because there is just too much personal information on screen. But these emails are from several different senders, received by several different email accounts. Everything is correct except that the "From" shown in the header pane is wrong. This is very obvious to me because I normally run entirely in the Unified Inbox with the emails sorted by the "From" information

One example is an email that is actually from "U.S. Department of Veterans Affairs <do-not-reply@notifications.va.gov>" which Thunderbird displays correctly in the preview pane (where I usually read my emails) and if I open the email itself, but the header pane says this email is From "Prepper-co <joshua@prepper-co.com>"

Another example is an email that is actually from "USPS Customer Support <uspscustomersupport@usps.gov>" but the header pane says it is from "Rainier Arms <sales@rainierarms.com" < p></sales@rainierarms.com">

These two examples were received in different email accounts that aren't even on the same server. I have other emails from these same senders that are shown correctly

I found this problem while using 150.0 (64-bit), which said 150.0.1 was available, so I restarted Thunderbird and it updated to 150.0.1 (64-bit) but the problem is the same.

========================================

A few days ago the left (file) pane went from

- InBox
- Drafts
- Sent
- Junk
- Spam
- Trash

to

- InBox
- Drafts
- Sent
- Spam
- Spam
- Trash

I attempted to change the first "Spam" back to the original "Junk"; didn't work. Have no clue why TBird decided to change the file names on its own.

Any information/direction(s) about how to correct this back to the original?

Thank you / appreciated. Nels

I have been shifting my email platform from Comcast to the new Yahoo platform. This has worked for my iPhone and for my Thunderbird app on my iMac. But NOTHING works for this on my MacBook Air. My gmail is fine, but the only way I can get to my new Yahoo platform is to sign in via the web browser. Thunderbird will not configure for the MacBook Air, and I've tried 10-15 different things already (not an expert by any means). I have all the proper settings. I have reinstalled Thunderbird on the latter machine.

I've downloaded Thunderbird in office PC and on PC at home. Almost I working in office PC or web mail but when I open Thunderbird at home, all my email lost in web mail and it's happened for such times. Is it a setting problem?! or, if it will be happen if using Android version ?! Thank you for your kindly assist!

thunderbrd version 153.0.1 64bit windows11 Spamfilter problem

my contacts are all in the personal address book convinced they get filtered as NOT SPAM, recently some addresses out of my adressbook get filtered anyway - weird an expert told me to setup a whitelist as a subfolder: I did but same prob... as far I know the address book works like a whitelist anyway, no success also not long ago thunderbird had an update - and it feels since the dodgy filtering started. Using thunbderbird for ages - never had that prob ever - till recent

Is there any known solution please ? Thanks & regards Jochen

Recently it's a daily occurrence that I must enter the password for my SMTP server. I always check "Use Password Manager to remember this password" but it doesn't help. The next day I'll have to go through this again.

I power on my machine multiple times each day, and I use Thunderbird each time. It doesn't happen each time. It seems to happen only the first time I use Thunderbird each day. This is new behavior. Before it would happen now and then, now it's daily.

I don't have a Primary Password. No need for it.

If you need to see the message I can send it to you, but I'm not attaching it right now because it shows my email address and the smtp destination. Maybe I'm being too careful.

Hello everyone.

Lately a get my emails from greek senders like in the screenshot, not everyone, but most of them. I tried many things like, changing mime variable from false to true, removing addons, repair folder, repair font to no avail. I also disabled antivirus. The questios marks are also in the "ctrl+U" screen and the fonts looks utf-8 as normal in the header. They look normal online or the yahoo mail app in iOS. Anyong knows how to fix this?

Thanks in regard.

Last week I deleted about 600 emails from the inbox, leaving about 500. I shut down the computer for 5 days then rebooted. TB seemed to start up ok. I deleted the remaining 500 emails. Emptied the trash folder. Tried to pull new emails to the inbox. I usually receive 100 - 200 emails per day but could not receive any this time.

I can see that there has been a reply or a messages was forwarded and when I right click for the menu "Open" may not even appear at times. When it does appear "Open in Conversation" is not always presented as an option even though there has clearly been conversation as I can locate reply's in the Sent folder. Sometimes it's there but when selected it opens a tab that only shows the email and none of the conversations. It's hit and miss and I can find no rhyme or reason. Any help would be greatly appreciated. Also, I would love to Testflight Thunderbird on Apple. Thanks, Sue

This happens regardless of whether message is moved to trash or junk folder. My concern are this also marks spam, phishing and/or malicious emails read which allows read receipt to be sent when enabled. I don't want to be forced to use remove immediately or disable read receipt option to ensure these messages are deleted unread.
