Thunderbird causes my machine to 'hang' from time to time, often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding" I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

I use easeus backup to save my thunderbird email profiles and i hope emails. I want to find a single email within the backup. I can access a dated backup no problem. issue is how do i read the thunderbird files... in folder profiles... to pop.gmail folder, where i hope the emails actually reside.

I’ve tried all versions of Thunderbird on my 2020 M1 Mac, and even though I log in correctly, it doesn’t load emails from my account. I used to use Thunderbird normally because I needed it, but I haven’t used it for two months, and now I see that it doesn’t work when I try to connect to my email. It connects to my email normally, but the problem is that when I click on “Inbox,” there's nothing there, and when I click “Fetch Mail” to try loading it again, a message pops up at the bottom saying everything is fine, but in the end, I still don't have those emails. What kind of error is this?

Before I recently (& reluctantly) upgraded to TB 140.8.1esr, I used to be able to paste the following in the Error Console to get a URI for an email message (or template) that I wanted to access from my calendaring app (EccoPro -- yeah, I know, one of those "from my dying hands" things, but it has never been equaled much less surpassed, just choked in the cradle by MS Office).

var hdr = gFolderDisplay.selectedMessage; alert(hdr.folder.getUriForMsg(hdr));

I would highlight the message I wanted to use, hit Shft-Ctrl -J, and paste that in the console.

I would get a notice with something like this which I could copy

"mailbox-message://nobody@Local%20Folders/Templates#10"

I could then put a clickable link in my calendaring app to run

"C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -mail "mailbox-message://nobody@Local%20Folders/Templates#10"

That message would open. Then I could hit Ctrl-E to edit it, paste as needed, and send .

This worked very well. I did not come up with it. I struck gold with Google and just copied it. With something similar to AutoHotKey I was able to automate it.

Now those URI codes no longer launch at all, and I cannot get new ones because when I paste

var hdr = gFolderDisplay.selectedMessage; alert(hdr.folder.getUriForMsg(hdr));

into Error Console I get

Uncaught ReferenceError: gFolderDisplay is not defined
   <anonymous> debugger eval code:1
   getEvalResult resource://devtools/server/actors/webconsole/eval-with-debugger.js:306

   evaluateJSAsync resource://devtools/server/actors/webconsole.js:788
   makeInfallible resource://devtools/shared/ThreadSafeDevToolsUtils.js:103

If I had known what I was doing in the first place, I might be able to adapt to this version of Thunderbird. Something obviously changed in how the Error Console operates or something.

Does anyone know anything about what command could generate a message URI so I could open it from another app using the command line?

Good morning . . . I have recently switched from an old Windows 10 machine to a new macmini, and have switched my Office 365 account over to it. Simply stated, Outlook is not working, and I have no desire to continue with it. Will Thunderbird suit my needs? Will it allow me to import my old contacts and emails, both from my Windows machine and the new MacOutlook?

Hi I am having problems signing into or adding my tpg account email address through both outlook and thunderbird. My address and passwords are correct and I have used the settings in both email programs as listed by the messaging company. The error message I am getting is that on thunder bird it cannot find the settings for my emaill account and on outlook it cant find the settings. I have had ongoing issues with my tpg account, this one is a pop3, since the messaging co took over the emails when tpg moved them to there. Issues are that i get very sporadic emails ie one week working the next nothing for long periods of time. I can successfully add gmail accounts to thunderbird and outlook without problems but the tpg one is my issue. I can get tpg emails through the gmail app on my phone with pop 3 settings but nothing on thunderbird. I have contacted the messaging co for help but other than settings they cannot help and suggested coming to thunderbird for help. I prefer to use thunderbird as my email program to have everything on one would be great again. Can anyone offer advice or assistance I would greatfully appreciate it

Please help! I have not received emails on thunderbird for a week. I have had to go through my web browser. I received messages that thunderbird is temporarily unavailable. What is the problem? How can I resolve this issue? Thank you very much!!

Inkommande mail kommer upp först då jag kört reparera-funktionen, men måste göra det varje gång. Bilagor kan inte öppnas av dem jag mailat till. Har provat skicka bilagorna i både text- och PDF-form.

Hi, I'm tring to rearrange the order of my email accounts in the left hand pane. The FAQ says sandwich icon -> account settings -> move them around in the desired order. This looks OK in the account settings list when I do that, but when I close it, the accounts order is as before, and this order shows up again when I re-open the account settings list. Is there any way to make this "stick"? Do I need to click some hidden Confirm button? Many thanks in advance!

I own two computers running MacOS 10.15.7 Catalina and have Thunderbird installed on both. Until rather recently, the Thunderbird version was 140.8.1. Then I noted that it was impossible to send e-mails, and soon discovered that the cause was outdated server settings. They could not handle office365, so I installed Thunderbird 148.01 and changed to settings that should be able to do so. This worked very well on one of the computers, the one which has a fast (SSD) hard drive, but not on the other that has a slow (non-SSD) drive. The error message that I get with the slow computer is, surprisingly, the same as I got with the older Thunderbird. But I suspect that the real cause is some kind of timed-out process.

If any of you could explain what happens and tell me what to do, I would be very happy. Maybe I should choose a Thunderbird version somehere between 140 and 148?

Thunderbird does not recognize my CenturyLink login password. This started yesterday. I can access my CenturyLink web mail. Have deleted my TB account and set up a new TB account without success. Have confirmed the account settings, etc. Assistance would be appreciated.

It seems lately that when I simply open a calendar entry to see what the contents are, then close it without making any changes, it sends an update to all those involved that something changed (as seen in the picture).

Also, when I accept an invite event and tell it not to send a response, it always does. This has been happening for as long as I can remember, and I cannot figure out a way to stop it, no matter what I do.

Anyone have any ideas for either of these issues?

I m using Linux Thunderbird 140.8.0esr Some emails have long unwrapped lines, how can i force a wrap boundary? e.g always wrap at 80 chrs or better yet, wrap to fit the viewing window

Hi there,

This one almost gave me a heart attack, naturally. It's pretty simple to reproduce:

1. Start a new reply to an existing email from someone. 2. Write for a while, stop. Thunderbird will save the message by uploading it to the IMAP server. 3. Open Gmail with the web or mobile app. The message will appear in the reply thread, without a "draft" label, as if it was sent to the recipient. 4. Edit the email again. Send. 5. Thunderbird will delete previous version. This is visible in the Gmail web client as "X deleted messages in this conversation." label and that's how I discovered it.

The recipient _appears_ to only see the latest version, but that's still kinda scary because it seemed like the draft was sent without the user clicking "Send".

Thanks!
