Hi, after upgrading the programs to version 115.10.1 after restarting, all folders in the folder panel disappeared. I still have all accounts visible in the account settings. I attach a screenshot.

I follow someone instructions: Menu icon > Help > More Troubleshooting Information Under 'Application Basics' - Profile Folder - click on 'Open Folder' A new window opens showing contents of your 'profile name' folder Exit Thunderbird now - this is important Scroll down - delete all of the following files.

   folderCache.json
   folderTree.json
   session.json
   xulstore.json 

Start Thunderbird With no results. Thank you for any help.

Hello. I am a registered Thunderbird donor. I was using Nebula 128 with no problems on a desktop computer with Windows 10. (The computer will not allow upgrades to Windows 11). All windows updates are installed properly. After updating yesterday to Nebula 130.b03 I can no longer send emails directly from Windows desktop explorer using the send to email recipient right click function (it does nothing) or from within an Office app (Excel and Powerpoint say there is a problem with the mail client and to restart the mail client, (which I have done multiple times). Word shows a Mapi error, which I include a picture of.

From within the app, I can send and receive emails with no problems, on my different accounts, but this lack of functionality is really aggravating. I would love to be able to rollback to 128, (not sure how to do so or if it's possible, and also if it wouldn't automatically update me back to 130)... or would also have to wait and see if the next update whenever that is fixes the problem.

I have obviously restarted both the computer and Thunderbird several times, with no luck. Tried running Thunderbird in troubleshooting mode, but had the same result.

Any help will be greatly appreciated. John

Running Thunderbird 128.1.1esr (64-bit) for Linux Mint (mint-001 - 1.0) on a Linux Mint 22 Wilma system. When I click Message Filters and then Filter Log, I do not actually see the filter log, only a check box to enable it, which is already checked" - same as https://support.mozilla.org/kn/questions/1438189 I noticed it today and, as I normally check the filterlog on my primary (POP3) account about once a week, it would appear to have only started happening recently. I checked the filterlog.html files for all of my accounts - they all looked OK. Went through TB Clear Log, Close for all of them, quit TB, reload TB, same as before. filterlogs not showing. Cleared 'Enable the Filter Log', quit TB, deleted filterlogs from profiles, reload TB, enabled filterlogs, quit TB, filterlogs had been recreated in profiles by TB. Reload TB, moved some filtered mails back to inbox, ran filters again, they had been moved from inbox to deleted, showed when filterlog.html viewed in Firefox but still not showing in TB via Message Filters and Filter Log. All help greatly appreciated.

I've installed Thunderbird 128.1.1 but it stalls on startup looking for a pw for a gmail I no longer have access to. This account was deleted 6 months ago. Today, I found one item in the account list under Local Files which I deleted. The problem persists.

All of a sudden my main inbox is not showing all my mail. The other mailboxes work fine. I don't know if I accidentally changed a setting. Can someone help, please? It's my main email.

Even if a new one comes in, it disappears. Some are in my all mail, but not all.

Please help. I am waiting for mail that is very important.

Thanks in advance, Leslie

Hello, I use TB intensely, and I have donated for its use. A week ago it automatically upgraded to esr, and since then, my search function has been essentially disabled. When I search the inbox or the all files, the program freezes for 10 minutes after I enter the first letter. It works fine when I search the sent messages. The software seems to prioritize message downloads and may be searching my google mail server rather than the downloaded messages. I tried without internet, and the delay is the same. I have windows 10. My husband's laptop remained in version 115, and it works fine. Please fix this bug urgently. I would greatly appreciate your help.

Here is a very strange problem: 1. all my notifications about interac are attributed to only one person: INTERAC e-Transfer: A money transfer from X has been automatically deposited. Under correspondents I have Y, no matter what X is. 2. When I do a global search for INTERAC, all notifications show up, but attributed to Z, different from X and Y. Further, Z only sent me an interac transfer once, maybe 10 years ago. Indeed, if I global search for Z, none of the interac notifications show up. 3. this is ONLY on Thunderbird, not at the server.

Any ideas?

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods."

I have installed Thunderbird version 128.1.1 esr (64 bit). The download button as not appearing. I removed the application & reinstalled. Still the download button is not appearing. Kindly help . I wish to have the button which I am used to. The screen shot is attached.

Hi. My windows 10 PC failed to boot a few days ago and after a long period of trying to salvage it, I wound up having to reset the Windows OS on it (Go figure) and that of course resulted in the loss of all of my 3rd party software and applications.

I have since restored the PC and and the My Thunderbird email software. I did have a backup of my profile of sorts from a few months ago when I was forced to migrate email ISP companies from Cox Communications to Yahoo when Cox left the email industry last spring. I say 'of sorts' because I only kept the file structure from the actual profile down vice from Thunderbird down. And even if I had done that, it wouldn't work well since I copied out the profile before the switch to Yahoo, so the email accounts have the old Cox server info not the current Yahoo ones.

I have come to terms with the email loss and I did take the opportunity to switch from POP3 to IMAP something I have been meaning to do for a while now. And I was able to copy over the Local Folders , so it's not all gloom and doom. But what I really need to get is the address book. I have tired to import it using the "import from another Thunderbird Installation" but that ended with an error condition. Is it possible to copy the address book from one profile to another?

Oh and one last thing, Thank you for the ISP configuration data base that T'bird used to auto-configure the IMAP server setups. It made life much easier.

Thanks for any help. Respectfully Mark B.

I use Greek letters Omega (Ω) and mu (μ) in electronics discussion, where the Greek Omega (Ω) is the symbol for "ohms" of electrical resistance to the flow of current, and Greek mu (μ) stands in for "micro" or millionths of an ampere of current (1μA is 1/1000,000th of an ampere of current flow).

I sent an email to others and my email account on which I use Thunderbird Mail (version 115.13.0 on Linux Mint). I artfully spelled in all caps the word "Communicator," using the Ω sign in the place of "O" and the μ sign in the place of a "U." I received the word with this spelling: "C?MM?NICATOR"

Checking in Firefox on my Gmail account's Sent folder, I found the Greek letters in good order. Firefox can use UTF-8 encoding.

I found a solved thread on the Stack Exchange. Look under Tools • Options, as it is in Windows, but in Linux that's Edit • Preferences • Display. I have neither Options nor Preferences in this version of Thunderbird, nor can I find anything about setting encoding in Edit • Settings. I should set encoding from Western to UTF-8 on both incoming and outgoing mail to see foreign characters.

Some info about my installations of Firefox and Thunderbird here: In order to not lose my profile when I need to reinstall Linux for whatever reason, I have both Profiles stored on an outboard disk that is treated as a permanent disk on the system. This move also gives the profiles room to expand as needed

Linux Mint 21.3 Cinnamon 64-bit MintBox Mini 2 Pro by CompuLab No longer on Amazon, but info here at the Linux Mint store .

So I ask, "Where to from here?"

This is a new Dell Precision 3260 with Windows 11 and a 1st time install of Thunderbird 128.1.1esr (64-bit)

By default Write, Reply, Forward are missing which may or may not be correct.

However the "View"->"Toolbars" ->"Customize" page shows all the buttons available but when any one is selected it cannot be dragged or saved, it's as if the customize option has been disabled.

Also the blue Save icon is always greyed-out.

Any help much appreciated. Thank you

I have been using Thunderbird for IMAP email for more than a decade. I have only two folders that contain emails on the server, Inbox and Sent. All the sent emails are there going back to 2009. I periodically move Inbox emails to local folders, but the emails from 2021 to now are still on the server. I see the headers for all of them in Thunderbird, but when I click on the header of an email from between mid-2022 and a few weeks ago, the result is blank. However, when I use my provider's Control Panel to read these emails, the texts and attachments are there, and I can read them. How can I restore my ability to read these emails in Thunderbird? I am hoping there is some simple setting…

Thanks for any help.

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.

While using Thunderbird, it mysteriously stopped connecting to Yahoo Mail. This happens every few years and I think it's related to Oauth2 credentials.

I generated a new secure mail key and copied it into Thunderbird but that didn't work. So then I checked online, and one of the steps in the Thunderbird instructions is: "Select 'Server Settings' for mail account; Set incoming server 'Authentication Method' to 'Oauth2'; Click on 'OK' ". But Oauth2 isn't one of the options. The choices are normal password, encrypted password, Kerberos/GSSAPI, and NTLM.

I'm using POP. Tbird version 115.11.1.

I am unable to send or receive emails after Xfinity upgraded our package. Whenever I try to use my email, the computer keeps asking me for a new password. I would like this issue resolved. Tks, Jim :-)

from membership in several mailing lists, I receive eMails in duplicate (where "duplicate" means identical in sender, date/time, subject and contents) in my inbox.

Is there any way to select (and delete) such duplicates?
