I'm using Win 11 and ver 140.3.1esr (64 bit)

Thunderbird works perfectly except for just one thing. Every time I write any email it freezes after about 2 minutes. If it's a short email, it gets sent. If it's longer, before I can get to the end, the program freezes, and I have to use Task Manager to stop it. No problem receiving and reading emails. This started about a month ago.

I use Bitdefender, but it still happens with that off. Windows is up to date. Any ideas why this is happening? Thanks.

Why for about the last week has Thunderbird been crashing when drafting a message? Often it saves a portion of the in-progress drafting, but not always. What is the fix?

This is an issue that cropped up with the last update to T-bird. It retrieves and displays emails as well as it always has, but now when composing an email reply, T-bird completely locks up, can't shut it down by any means other than using Task Manager and killing the process. Before killing it, though I expanded T-bird's processes, and it listed five instances, one of which read "Not responding." When this happens, the cooling fan in the laptop kicks into high gear, until shortly after I kill T-bird.

Needless to say, this is intensely annoying and inconvenient. I belong to an extremely busy recovery group, and email is my primary contact with them, so this makes things a royal pain. I've had to resort to hitting "Respond" to open a new email, then firing up the text editor to compose the reply, then cut/paste that in and send it. Workable, but really... it *was* working fine, and now it isn't, and I haven't changed a thing, Windows hasn't updated, no new apps or anything... it just stopped working.

I've tried a number of suggested fixes, such as removing all add-ons (removed, not disabled) and themes, creating a new account (which worked okay for about a week, then it too started locking up). About the only thing I haven't tried yet is uninstalling T-bird and re-installing it, which I'll do if I absolutely have to, but I'd rather not go through the hassle of rebuilding everything if there's any other way to fix this.

Is there any kind of information or file/s I can provide that someone may be able to make some sense of? I'd REALLY appreciate it. I've used T-bird since I had internet access (back when Alta Vista was still a thing), and I love it - - no other email app offers the breadth of features that T-bird does, even paid apps. I'd truly HATE to have to switch to something else over this!!

Thunderbird has worked fine for me for years on my Windows 10 Pro machine. The computer works perfectly otherwise--and has a large amount of RAM. But a few weeks ago, Thunderbird started freezing (stops responding) at some point while I'm writing a message.

What happens is that I'll start to write an e-mail message in Thunderbird, and at some random point (from a few seconds to a few minutes) it will stop adding what I'm typing, and soon the text that it was showing grays out. It will then say Thunderbird has stopped responding, and I have no other choice than to close Thunderbird. I have no way of saving or recovering the message I had been typing--very frustrating!

As a partial work-around, I found that if I click on "Save" every time I add a little more to the message I'm trying to write, then at least when I restart Thunderbird I can go to Drafts and recover the message (as it was the last time I clicked "Save").

Thunderbird still works fine for all other functions (reading received messages, etc.). It only has the stopping responding problem randomly when I'm trying to write a message. It can happen while I'm typing--or during a pause between writing sentences. And the timing of the problem is very random and variable (from almost immediate to a few minutes). I tried running Thunderbird in Safe mode, but the problem was the same...

I always keep up with Thunderbird updates. Currently, I'm using version 140.1.1esr.

Can you give me any help with a solution? This problem is maddening!

Thank you,

Vincent Andrunas

In recent weeks, Thunderbird often hangs when I'm replying to another email and have written a sentence or two. It never recovers, and I have to close the program from Windows.

It doesn't always do this. On a few occasions, if I wait a while, close Thunderbird from Windows, and restart it, the partial is in the Drafts folder.

I'm running Windows 11 24H2, but I've been on 24H2 since December, and this problem is more recent.

Great, so I fix one problem, only to be confronted with a shiny brand NEW problem.

Version 141.0

Fixed the "T-bird lockup" when composing emails, so that's no longer an issue - - YAY.

Now, Tbird refuses to save drafts. I had it set to every minute while I was having issues with lockups; now, I'm seeing a "can't save draft' popup every minute. I mean really... I haven't changed ONE thing in the machine other than changing that "0" to a "1" in "about:settings." Is there something about that particular fix that could cause this "save no drafts" issue?

Don't have a clue where to even begin, since it cites either network issues OR file-access issues, and I fail to see why either would suddenly be an issue where it wasn't prior to fixing the lockups.

Anyone have any pointers where to start looking? I keep seeing reference to Tbird "logs," but have no idea where to find those. Seems a reasonable place to start (after all, it's the first thing I look at when my 3D printer goes nuts!)

Hi,

I'm trying to move Thunderbird from my Windows 10 laptop to one where I just installed Linux (Zorin Pro 17.3). I followed the instructions here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I installed Thunderbird 140.4.0 esr, which is the latest version. Both laptops now have that version installed.

But when I open TB on the Linux computer, and close the Account Setup window, and go to the Troubleshooting screen, next to "Profile Directory" it says "Open Directory", but when I click on that, nothing happens. So how can I paste my TB profile? Do I have to start a new profile first, and then copy over that?

I installed TB from the "Software" area, which I believe is a Flatpak. I'm very new to Linux, so just fumbling around here. There were 3 options of Thunderbird. I installed the one that had the most information and seemed most up to date. That was confusing.

I would LOVE some help on this.

Thanks!

in the last couple of days thunderbird has stopped showing emails from one particular account. Inbox is only showing messages up to yesterday, and all mail is only showing to the day before (?). The messages are on the proton webmail inbox ok, and are received by the proton mail app on my phone. I have not changed any settings, and it worked perfectly before now

my email is not synced to my phone or my other computer on my new Win11 computer . Yahoo is but not Thunderbird . I have to mark as read or delete messages that have been read on other devices when I get to this Win 11 machine . Thanks ! Ken

Hello, Here is what I consider a new bug in TB. It goes this way: While I am reading a message in the message pane of the standard window (not in its own window), if messages arrive (with a small ding for me), the message pane I am reading goes BLANK and the message I was reading is deselected. I have to reselect the message I am reading and scroll down to where I was. This behavior is very annoying and did not exists in previous versions.

I hope this helps. Thank you , Alain Damlamian

Hi, lot of years ago I have changed TB to use maildir ibstead of mbox for new accounts, Now I met some filtering issue I can't fix and it is proabely caused by maildir.

So I'd like to set TB to use mbox with new accounts instead of maildir.

Some additional info: TB 144.0.1 (64 bit), win 10 pro, I have 4 mbox accounts and one maildir account.

There is no need to export / import / keep data existing on maildir account. I can remove it with no pain. I just want to setup TB to create new accounts as mbox again.

Any help will be appreciated.

TIA

Everthing was fine but last night it stopped sending emails saying verification failed for my email address. I installed this on my phone yesterday and imported info from desktop version

Is there a way to make the “Today” tile stand out more clearly in the calendar month view? The currently selected day is displayed with a light gray background and stands out, but the actual day is only modestly marked by the day number. With many entries in the calendar, it is therefore difficult to recognize. I would therefore like to see a user-selectable background for the current day.

Not exactly , when I delete a message on my other computer or my phone they are not deleted on my Win 11 computer . My phone and Win7 computer seem act as if they are connected , my win 11 computer doesn't know that emails were read or deleted on the other system . Yahoo email seems to work across all , just not Thunderbird .

I added two accounts to my Thunderbird installation, mine and my wife's. Both show the same one Profile folder in Help > Troubleshooting. But when I backup these huge folders (Local and Roaming) by copying them, only my email address seems to be present in file and subfolder names, not my wife's. Is her account not there in my Profile? Why? Can I get it in there?

There is an mystery icon like an orange dot that appears alongside certain messages in the message list. I have attached a picture. Can anyone explain what it indicates.

I can tell you that it is NOT any of the following.

• Unread message indicator (these are shown in bold and have a green dot in another column)
• Junk mail indicator
• Threading indicator

All suggestions gratefully received.

When I try to add a new Mail Account, the "Looking up configuration" step hangs indefinitely. I have to force a hard exit to reopen the app. I was able to add my hotmail account without issue, but now that I'm trying to add @yahoo.co.uk , it just freezes up. Thx

Windows 10, newest Thunderbird.
