When I downloaded the Thunderbird app to my new laptop and opened it, it already had a fortnight's worth of recent messages in the Inbox, plus many of my Sent messages. However, the remainder of the Inbox, dating back to 2010, was not there, neither were my address books. Why didn't a clean copy of the app download so I can import my Profiles? In addition, my old laptop uses POP incoming, but the new laptop seems to be configured to IMAP. Is this a problem, and if so, which should I choose for the new laptop?

I recently lost Internet and waiting for new provider 12/6. I get msg " pls enter your Primary Password on Thunderbird. The one I've had for years fails and new choice through the Mozilla help reset area fails too.....is reset dependent on broadband/Internet? I have inet on phone but CANNOT transfer usage to desktop!!! ? help?

New computer Ubuntu 24.04 Mate, older Ubuntu 22.04 Cinnamon. Following support transfer directions (open Thunderbird on new PC, close it, paste a copy of older .thunderbird from USB stick to .thunderbird on new, over write), when I open Thunderbird no accounts are shown only the create account screen. I find no update path for older Thunderbird. New PC came with 128 esr but I found a tarball of 115 .18.0, installed it and followed transfer directions with the same results. Seems like the esr version uses a profile ending with esr and ignores my older one. What are my options for transferring 20 years of significant messages? The hard way might be to identify the account specific files in my older profile and copy them into the new esr profile...

Since yesterday Thunderbird cannot download messages.

It says "Downloading 1 of 4 messages" and attempts for a while, then stops. No messages are downloaded.

one of our email addresses was hacked so we changed the password on that one email account but now we have a pop up window every time we open thunderbird asking to enter the password for two of our addresses. The system won't accept the original password nor the new one. It keeps saying it failed so I can't get into my account passwords screen to see what is going on. We are getting our emails. just that darn window keeps popping up every time. we can send emails too.

Yesterday sometime I accidentally deleted my calendar program and it's a killer I need it bad and if I can't get it I need a simple easy to use replacement it's not asking me a hundred questions just because I want to keep somebody's phone number but what I really want to do is try and find the program a little more before I give up where do deleted products go?

Am unable to receive messages from Gmail over the past 2-3 days. Email from other sources are fine. Our Email provider here in Oz is 'The Messaging Co'. They don't respond to our queries. thanks in advance. Confused

Hi all

I have my sent mail going into my Inbox be default, so that I can see entire threads in context. It's set that way in Copies & Folders in each of my email accounts. However, I frequently find sent emails in the Sent Mail folder.

Can anyone offer an idea of why, and how to fix it?

Thanks Edwin

On both MAC and PC versions. I recently installed a new SSL certificate on one of our company servers. It works on most email applications without issue (Apple Mail, Outlook etc.) - but Thunderbird is complaining about the certificate. The certificate is coming from: sectigo.com

The error is: unknown identity The certificate is not trusted because it hasn't been verified as issued by a trusted authority using a secure signature.

If I confirm the default exception - it uses port: 443 - instead of ports 995 and 465.

A certificate exception has to be deployed by adding network.security.ports.banned.override to the configure editor. Adding a string of 995 and then 465 to make the exceptions. It doesn't always work....

I have used multiple online scanners and they all give green lights on the certificate. Any help appreciated... I have no idea where to go from here.

Hi everyone.

Hoping someone may be able to help. I see that other users are able to fully highlight the events in calendar. I seem to be only able to highlight 2/3's (see image)

Thanks in advance

The inbox on my default email account (cfgait@gmail.com) was showing that I have new messages. The total was not highlighted in its usual blue but since I'm colorblind, I can't tell you what the color is. Obviously, something is out of sync. The mail tool thinks I have new messages (which, in fact I did because I checked them using the Chrome browser) but the mail tool could not or would not display them. This seems to have started happening ever since I downloaded the latest 128.12.0esr (64-bit) release (esr). I deleted my account and added it back in. Unfortunately, I also lost all of my email rules. What can I do to recover?

Have just installed TB for the first time (replacing WLM) and am very happy with it. My only problem is that the option to open with a blank page is not working despite leaving the checkbox unchecked. I've tried checking and unchecking but it makes no difference, it always opens with the full setup options displayed. Is there another way to have TB open with a blank page?

Sometime in the past year or two, ONE of my four accounts started starring (putting the yellow star) on ALL emails I sent from that account.

This is not happening in the other accounts, including an account from the same university email system. If I send an email from the affected account (cischair) it is starred when viewed in cischair but not in the other account I sent it to (suthers). If I send an email from the other account, suthers, to cischair, it is not started in either account but my reply from cischair to suthers will be starred, again only when viewed in cischair, not in suthers.

It's very annoying to have to uncheck the stars on everything I send, and makes them useless.

Of course, I have looked in Account Settings for something that turns this on and off, and have not found anything.

Could you tell me where this might be set, or perhaps inadvertently by some keystroke combination (the bane of usability)?

Thanks - Dan

I was searching for an email that I had just deleted and discovered that the Trash folder connected to my inbox was empty. The one connected to my Local folders, however, was not. I cannot find a setting that would instruct Thunderbird on how long to save emails in the Trash folder and am sure I did not accidentally change anything. Any idea how to fix this?

I'm aware of the many caveats regarding use of 'Repair Folder'. It's widely known that the results are...inconsistent, to put it charitably. Nevertheless...

I keep vast quantities of messages in local folders. For some of those folders, I manually archive the contents annually, by creating a new folder with the name of the year ("2025"), then dragging messages from the existing folder to the new folder. This sometimes works. More often than not though, it fails in one way or another. Sometimes I drag them across, a handful of them show up in the new folder, but then the rest just sit there in the old folder, in selected state, but with no activity taking place. Sometimes merely selecting smaller 'chunks' of messages to drag across will work. In others, such as last night, even that didn't work.

I then invoked 'Repair Folder' in a vain attempt at recovery; sometimes that will clear the issue. However, when I did this, what happened is that the chunk of messages that were selected wound up having all their date fields (in the display) reset to near the epoch - January 20, 1970. When I view the message source, the dates are correct.

I'm unable to find a way to recover from this.

Any advice would be appreciated.

Windows 10 Pro 22H2 Thunderbird 128.11.1esr (64bit)

I use Thunderbird for several yahoo email addresses that I have. Yesterday the one account wasn't transferring over from yahoo so I deleted it and then reinitiated it (POP server setting). I've done this before with another email address I have and it worked, but things must have been set up differently this time as it no longer showed any of my older emails (apparently only showed what was still present at Yahoo's site). My understanding is that my old emails would still be saved on my computer (Windows 10), and I went through the steps on Thunderbird to get to where the stuff is on my computer but when I open any of what appear to be the stored emails, everything is coded in such a way that it's near impossible to read. I'm hoping I can somehow transfer them back to Thunderbird somewhere or, if not, open the file so I can at least read them easily. The Local Folders file that's currently on Thunderbird for some reason has stuff from another email address I have (I believe that one is imap and not POP). I'm very uncomputer savvy, so any help I can get would be greatly appreciated so I don't mess things up more. Thank you

I have an 8 year old PC that I have been using Thunderbird on its entire life. I have 5 email accounts (from my own website if that matters) on it for personal use that have tons of information.

I bought a new computer and have not been able to move my old data to it. The old computer uses Windows 10 with Thunderbird Version 115.5.2 (32 bit). The new computer uses Windows 11 and I have tried several Thunderbird versions with the current one being 128.12 0esr (32 bit). I have added one of my email accounts to my new computer, but it contains none of my previous data (emails, contacts, directories, etc.), just a bare bones account that only receives new email.

I have repeatedly tried to move my entire source computer setup and data going through all of the described steps including copying the previous Thunderbird folder to a flash drive. I then follow the directions for copying and pasting my source data into the new computer's "roaming" section. It goes through all the steps including asking if I want to overwrite existing files. I have almost 14,000 files and as the process continues, I can see file names being added just as I would expect.

After everything is complete, when I restart Thunderbird, the only access I have is once again to the bare bones new email account. There is no data, nothing at all, from my source computer.

Help please, this has gotten beyond frustrating.

Has anyone had this problem where the headers download but you CANNOT see the contents of the email? If so, has anyone found a solution to being able to see the contents. Centurylink email support is a joke.

GOAL: I am trying to get off of Centurylink but I have lots (OVER 20 years) of important (health and support group related) emails (thousands) that I would like to retain the full contents to and move the mail to my live.com account. I figured out how to set up the other account on Thunderbird already but can not get the full email on my primary Centurylink (Q.COM) account to download. I think I configured the download options correctly but am not sure. See attached.

Thanks in advance!

I have 2 accounts in TB. In one of them Thunderbird has a folder named 'Junkmail' but on the server the folder is called 'Spam.' Thunderbird is not allowing me to rename the folder.

Any reason for the discrepancy?
