After updating my Thunderbird mail application from version 128 to 140, the shortcut icon for composing a message is no longer responsive and I cannot create a new message from it. I can no longer create a new message without right-clicking on a sent email and using “Edit as New Message (E)”. How can I get back to being able to create a message from the message creation shortcut?

I cannot send emails and always get the same error message, no matter what steps I have taken. This has been the situation for nearly 48 hours. During this time I have undertaken the following steps, as advised by Thunderbird (TB)/ Optus and Google (not in order).

Checked SMTP server settings (many times), Re-booted the Router, Uninstalled and reinstalled TB, Changed the number of Server Connections to Cache from 5, down to 1 (as suggested by the TB Notification), Tried sending a test message to my other email address on several occasions, but got the same error message. I have checked my Webmail account and can send and receive from and to my email accounts from within webmail.

As required in the TB help file, The following information is provided: SMTP settings (attached). Mail Provider is Optusnet. ISP is Firefox. Antivirus is Trend Micro Maximum Security Version 17.9. OS (details attached).

If I have neglected any required info please ask. Any assistance would be greatly appreciated.

Thank you. Flin

I'd like my search results to include messages where the search item is in the Sender or Subject but it appears to find only words in the body. Is there a way to include this? btw, the window pane on the left shows a filter but I don't know how it got there or how to delete it. Is this relevant? Is there documentation on how to use the search feature to specify folders, binary searches, etc? Thanks

Hello,

My Thunderbird 128.12.0esr (64-bit) was working fine. It no longer displays any messages except the latest ones. They are filtered, they disappear into their folders, I can only see them directly on the email server. I also have version 140.3.0esr (64-bit), but it asks me to create my accounts from scratch. (Mozilla Thunderbird Flatpak en-USthunderbird-flatpak - 1.0 release notes).

Thanks for your help!

Bonjour, Depuis quelques temps j'ai un soucis d'envoi avec ma boite mail. J'ai deux adresses mails : davangel49@orange. et gaecterrien49@orange.fr Avec l'adresse privée, je peux envoyer et recevoir sans problème Avec l'adresse pro (gaecterrien49@orange.fr), je peux seulement recevoir des messages mais pas envoyer. J'ai une message d'erreur qui s'affiche et qui me dit "mail rejeté. Identifiant et adresse mail appartenant à deux utilisateurs différents".

J'ai contacté Orange également. Le problème a bien été réglé de leur coté (je peux envoyer un mail et le recevoir de ma boite mail Orange sur gaecterrien49@orange.fr mais pas à partir de Thunderbird. Pouvez-vous m'aider à régler ce problème? D'avance merci A. TERRIEN

i cannot get Gmail configured in Thunderbird. ive deleted it and re tried countless times but is keeps saying wrong credentials. ive followed all the guides and done everything . what is NOT happening , is Thunderbird does not open a browser to sign in with google. why?

Enough is enough—every update brings problems, crucial add-ons stop working, and now drag and drop attachments have stopped working. It's really inconvenient. Maybe it's time to stop this nonsense and implement paid subscriptions or purchases, but in a way that makes everything work.

Hello, Apparently, when changing the name of the .thunderbird folder, to hide it, Thunderbird 140.3.0esr (64 bits) continues to exhibit messages. I do not find where they are located. Any idea? Thanks SG

Recently when I have opened Thunderbird I have found that there are no emails at all in any of the folders, and the message says "No Emails found" although the count shows that there are nine. This is the same for all my email accounts. If I open help and go through the troubleshoot they all come back. Its not the ad-on's, as when I disable them the Emails still do not show. The version of thunderbird that i am using is145.0 (64 bit).

Help please.

Drag and Drop attachments to the desktop stopped working again with Thunderbird 145. Steps to reproduce: You receive a mail with an attachment. You drag an attached file from this message and drop it onto the desktop of your Mac to download it. The attached file is not saved to the desktop (or any other folder I tried). This is on MacOS 26.1 MacMini M4. Please fix asap.

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

I'm using a Windows 11 laptop with a 14" laptop with a 1920 x 1200 resolution. I'm using Thunderbird to access 5 email accounts, calendars and cardBook. I'm looking for suggestions and tips about the best layout to maximise the display of my email information with the minimum of scrolling.

Thank you.

Running Linux Mint 22.2 Cinnamon and it has just updated Thunderbird to V140.5.0esr. Reopening TB all my carefully crafted layout has disappeared. I can only see one account with favourite folders underneath. I can't see the Sent Mail folders or the Personal folders which I rely on heavily, nor any of the other accounts. This has totally messed up my day.

I have the Folder Page View Switcher in, that was working after the upgrade but I innocently changed a setting on it, and it disappeared. I cannot find anything to bring it back.

Can I revert to a last good set up?

Please help.

Hi!

I have recently installed Thunderbird (version 145.0 (64-bit) on my PC (I have Windows 10) and have configured my IMAP account without any real issues.

Except from one thing:

Among my email folders (rather much in the bottom of the folder structure) I see a bunch of "weak" folders (see attached image) – with the name in a greyish tone rather than the normal black. None of them contains any emails (in other words empty), but they seem to be copies of random existing folders as well as previously deleted folders. They all have the same prefix – ”INBOX”

When I right click on them I can delete them, but as soon as I restart Thunderbird (and/or the computer) they reappear.

I have already tried the following: 1. Going to Settings -->Account Settings --> Server settings and ticking the box Clean the Inbox at closing. That didn’t solve the problem either. 2. Right click on them and going to Properties and tried Repair folder. Nothing happens. (I might not have the right terms/vocabulation since I have the Swedish version of Thunderbird.)

My questions regarding this matter:

1. Why do these folders appear in the first place? 2. Is there a way to get rid of them?

Thanks in advance.

I have read what is posted on adding a folder in Thunderbird.

The problem I am experiencing is that when I select the main account and add a folder it keeps placing the folder as a sub folder of the in box not a folder or sub-folder of itself.

I am perplexed.

Thank you for your help!

Something changed. I’ve tried to set up my old AOL email account multiple times using different default browsers, and the setup typically fails. Using Edge, I get “Edge: Too Many Requests” . Using Firefox, I get “Waiting for authorization in login popup…” and then the old rotating arrow. After about a minute delay, the Account Hub reports “Authentication error.” The Thunderbird Account Hub reports the outgoing server settings test good. I’ve changed my AOL email password, and have an AOL application password ready to use, but never get asked. I’ve turned off two-step verification in AOL, but same Thunderbird behavior. I’ve got multiple computers, and this issue is the same on all. I’ve had no problem adding a Gmail and SBCGlobal.net account. Thunderbird is 144.0.1 (64-bit) release. Windows 11 Home, version 25H2. I really don't want to give up Thunderbird, but I need this account badly.

In the past, when I had replies on emails I sent, they always came back as a separate email even though the subject line was the same (since it's a reply). This was with my old email server that was a POP3 setup. Anyway, when I created a POP3 Gmail account, now I noticed that the emails that are a reply get stacked like subdirectories in your filing system. That is, my original message is the first tab, then each subsequent reply is in a new tab so I could have 5 or more stacked tabs. The problem I have is that even though the latest reply might be the newest in date, when I'm in the main email menu showing all the emails I've received, this particular email is at the top of the list because the latest reply is the newest email, however the original date stamp is showing when I created that email rather than the date stamp of the newest reply.

Is there a way in the settings or something to have each reply as a separate email like I did with my old server? Or is this some kind of quirk because of the way Gmail does POP3? The reason I opted for POP3 is because I wanted the emails stored locally on my PC and I could delete all emails from the Gmail server rather than using the synchronizing method of IMAP where all my PCs would have the same emails (using POP3 I could have different emails stored on each PC as I could delete some on one PC while having them exist on another one). Thanks in advance for any suggestions you may offer!

I'm just getting set up with Thunderbird. I used to use Postbox, and imported my Postbox profile into Thunderbird, which overall worked great – it got all my local email folders, and brought in my Apple email account, and so forth. The only wrinkle I've noticed so far is that it also created an account named "server7.invalid" that I can't delete. If I go to Account Settings, for "server7.invalid" it states "The following is a special account. There are no identities associated with it." The only items underneath it are "Spam Settings" and "Disk Space". There is no red Delete button for it, the way there is for my two real (IMAP) email accounts. Viewed on the Mail tab, it appears to contain only "Trash" and "Outbox", and both of those are empty. This weird invalid account doesn't seem to be doing any harm, but of course it is ugly and I just want it to go away. Help?

Hello,

I have to add the Password every time I open Thunderbird because I removed the Password myself after I read this:

<<<< ThundaMike Mozilla Staff 7/28/25, 9:15 PM more options Sounds like you are almost there.

Building off what @david said above, try this:

In Thunderbird, go to Settings > Privacy & Security.

Scroll down to the Passwords section and click Saved Passwords….

Find your email account in the list and remove the saved password.

Restart Thunderbird.

When prompted, enter your new password. >>>

My doing this it removed the .twc password Log In totally in that Settings. I do not see the "my twc.com" in the settings of Tools, Privacy & Security, then Saved Passwords in the list, I only see the Hotmail account settings I have in Thunderbird. Removing it like ThundaMike wrote really removed all the TWC Password and Information.

Can someone help me restoring or re-enter my Mozilla Thunderbird info back into Tools, Privacy & Security, then Saved Passwords so I do not have to type in the Password every time I open Thunderbird.

Thank you so much for your time and efforts I truly appreciate it.
