After automatic updating to Thunderbird 140esr under MacOS 12.7.5 Thunderbird will not connect to provider. Same happens with installation of version 150. Same happens under Mac OS Tahoo. I can't make a new profile because of this. What can I do to solve the problem ?

When I try to open Thunderbird it keeps giving me a message that it is trying trouble install a new helper tool and asks for my password. I do so, hit the Install Helper button, and then nothing ever happens. I get a spinning beach ball and it never opens no long how I wait. I would be very grateful for any suggestions or advice on what to do.

Thunderbird causes my machine to 'hang' from time to time,

1. 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.

2. 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"

3. 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.

4. 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.

1) Sometimes you need to saven a print screen of the email the way it arrived. You do that by making a print screen form the email in the viewer. This is not only compact, but holds data one needs as proof of how and when the e-mail arrived. When you do that on the dat the email arrived or was sent, you can see the time, but not the date. So you have to remember to make a print screen the next day. Because only than you can see a date. Is it possible to show a date of today when an incoming or sent email is viewed in the viewer. 2) Sometimes you want to convert an email to an agenda item next week or so. When you do that, you cab see the full text of the email appearing in the agenda item, but not the date you received or sent this email. That is unpractical. Can you fix this?

After several automatic upgrades of Thunderbird to version 150.0, I all of a sudden can't connect with the pop3 server provided by my ISP.

Troubleshooting information is as follows:

I've never had a problem before but suddenly I'm getting an error when I try to log into one of my accounts telling me "The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded [AUTH] invalid credentials. Why is this happening now?

I have 4 other accounts on Thunderbird and this is the only one that has started giving me problems.

I recently created a Google Workspace account. There, I have a user profile with a custom email address. I've set up the new account in Thunderbird, and it is working as expected. If I send a message from my "external" account to the workspace account, it arrives, and I'm able to reply back.

One feature of Google Workspace is what they call "alternate email" addresses. They sort of work as an alias for the native address. I have created one such alternate. If I send a message from my external account to the alias, it arrives correctly in the workspace account. However, when I reply from the workspace account, it does not go back to the originating address, but instead it is addressed back to the alias. If I repeat the experiment from the Gmail web interface, it replies to the correct address.

I've downloaded all the headers, and the Return-Path tag is correct. I can provide the full header if needed.

It feels like there is an invisible forwarding action to get from the alias to the workspace account, and that the reply action is incorrectly finding the interim alias. But that doesn't really seem to be what I see in the headers - although I'm probably not the most expert reader of those.

And it isn't necessarily a Thunderbird issue. I can see that there could be something going on with Google. But this is a good place to start...  :-)

Using Thunderbird forever, on my PC and also on my Android. On my PC sending messages stopped working "suddenly". (That means I did not change anything in Thunderbird. Windows related settings - who knows.)

__________________ Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.ionos.de failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again. __________________

I have checked the SMTP server settings again, but it didn't solve the problem. I have changed my password of my e-mail account to anew one, reinstalled Thunderbird and recreated my account, but without anything changing. Receiving works, sending does not. Tried to install Outlook (sorry, just temporarily, I hope :) ) and there everything works just fine.

Maybe some Windows Firewall setting? Didn't find anything that seems to prevent Thunderbird from sending thou. Do you have any idea?

I wish to move away from MS outlook. I have installed Thunderbird desktop email client to my Imac apple desk top computer. When I run the installation software and input my gmail account details the system responds with an error "Authentication error". can you please help me to reconfigure the set up to resolve this problem. Kind regards Terry Davies.

Since April 9, 6:14 PM CDT, most folders (e.g., Drafts, Templates, Sent) on my primary laptop in my primary POP email account, [edited]@bdcusa.com, have disappeared; and ALL SUBfolders in my Inbox have disappeared. Over 185,000 emails have vanished overnight!

On my primary laptop, I'm using Thunderbird 149.0.1 (64-bit) on the release update channel, still running 64-bit Windows 10 Professional, and have nothing backed up to the cloud.

Fortunately, on my secondary laptop, I'm using Thunderbird 115.18.0 (32-bit) on the esr update channel, running 32-bit Windows 7 Professional. I say, "fortunately," because ALL folders and emails are still there, so I know they haven't been vaporized!

How do I return all folders and emails for this email account to visibility and access on my primary laptop? Detailed directions appreciated.

A few weeks ago, my Thunderbird went very, very slow. It has from time to time crashed. Now this happens whenever I start a new email. If I downloaded Firefox, would that help?

So I have Thunderbird set to autosave every 5 mins.

I was drafting an email, where I had written quite a lot of text (as a reply) and for some reason my text went missing and there was no undo in edits

So I quit and went to drafts, nothing there.

I checked and autosave is on for 5 mins.

hit reply again. typed in some text, set a timer for 12 mins, quit.

Again, no save.

So why is "Auto Save ever " x mins not working?

I have tried using both a zip and unzip folders along with a backup folder for moving an export of the calendar. I export file is larger than 2GB and i find no way to make it smaller. or i can not find a way to export a pure csv file. All the above fails on import. please advise

Hello, I use Thunderbird 140.10.0esr, installed as Flathub flatpak on Fedora Linux Kinoite. I just found out I have a folder in /home/<user>/.var/app/org.mozilla.Thunderbird/.thunderbird/1tniiwpw.default-release-1/storage/default/ called https+++www.googletagmanager.com. I wonder why I have this and what it does in the Thunderbird settings. It has something to do with Google's LLC, but I don't want to be part of that. I removed the folder completely and hope it won't come back, but I wonder. Who can tell me something more about this folder? Thanks.

I had a gmail email in my Thunderbird, during setup I had to get permission from gmail to connect using google api. All was good. I have since deleted the account from Thunderbird, restarted app and pc many many times and yet no matter what i do , thunderbird continuously brings up a message "Verify its you, Google need to verify its yo" like its still tryijng to connect. I have tried everyhting all suggestions on the internet and it still asks me as if the act was still attached. Its SO annoying as it pops up all the time. Please help me get rid of this
