I cannot send from my default e-mail account. I get error message: Sending of the message failed. Connection to outgoing server ( SMTP ) smtp.broadband.rogers.com was lost in middle of transaction. What is wrong?

Hi all, After receiving emails I select a group and hit delete. The emails turn grey but dont delete . I have to pick them one by one a second time in order for them to delete. This has just started in the last few days. Is there a setting I'm missing? I just want the emails to all delete the first time I hit the delete button. Any help appreciated Dan

Hi Thunderbird Support Team,

I recently installed the latest version of Thunderbird in a Hyper-V virtual machine and encountered the following message: " Approval required Mozilla Thunderbird This app requires your admin's approval to: Read and write access to mailboxes via IMAP. Read and write access to mailboxes via POP.

Allows the app to have the same access to mailboxes as the signed-in user via POP protocol.

This is a permission requested to access your data in xx Send emails from mailboxes using SMTP AUTH. Maintain access to data you have given it access to View users' basic profile"

This was functioning with the previous version of Thunderbird, but now my IT team requires additional information about what the app is trying to do with our Office 365 environment. The approval process is crucial because some apps may introduce security risks or seek extensive access to our Office 365 resources.

Could you please provide more detailed information on the permissions requested and the specific changes in this version compared to previous versions? This will help in getting the necessary approval from our IT team.

Thank you for your assistance.

Best regards, Jenny

I am having trouble connecting to Earthlink.net to download my email. I can send out email but not receive them. Apparently, the imap is missing for some reason. Thanks

For several months, I have not been able to create, delete, or rename local folders. I am running 128.3.2esr (64-bit). How can I resolve this? Here is a capture of the error console for a single attempt to rename a local folder: NotFoundError: No such JSProcessActor 'BrowserToolboxDevToolsProcess' Uncaught NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsISpamSettings.spamFolderURI]

First noticed that the Help About screen says "Unable to check for updates due to internal error. Updates available at https://www.thunderbird.net/"

Then trying to view Settings to change automatic update, it will not display. Account settings will display, not general Thunderbird Settings.

Tried to reinstall Thunderbird but did not fix the problem.

I use the latest version of Thunderbird on MacOS Sonoma 14.6.1. I have had a strange login/security issue twice in the past two weeks.

First activity in the morning about 10 days ago I noticed Thunderbird displaying many "Unable to get email, password incorrect messages" stacked on top of each other. Other native email clients on my other Apple devices were also unable to retrieve email. I contacted the email provider and they said the account was sending spam and they had blocked the account. They could offer no other information, such as whether the account had been hacked or password changed. After going through their security protocols they were able to restore the account and I changed the account password, from a reasonably strong 6 random characters to very strong 16 random characters with multifactor authentication enabled. After restarting Thunderbird, it was not possible to set the client password and get the client to function. I restored the profile from an older backup, copied the current mail folders into it, started Thunderbird, set the email password, and it started functioning again.

Today, about ten days later, first activity in the morning again found Thunderbird in the above state with numerous stacked password incorrect messages. However, this time email is functioning on my other devices, and I was able to login normally to my email provider's administration system. Perhaps the timing was such that the provider had not yet detected an issue and frozen the account.

This would lead me to believe that something on my Mac or associated with Thunderbird was responsible for the issues I am having. Multiple scans of the computer with Malewarebytes finds no viruses on the system. All help is appreciated.

Hi. Using Posteo with Thunderbird, Windows 10.

Twice now an email has simply vanished when all I did was left-click on the email in the left side pane email list, i.e. the Subject line heading. Each time it is an email sent to my Posteo email address, not anything synced.

I did not click on Delete or anything else.

I have searched every folder for the missing emails, they are nowhere to be found. They are not in the Deleted items folder or any other folder.

This is a recent problem, in the last few weeks.

I checked on my Posteo webmail, and there is no sign of the emails there either - so they have vanished from both. Inexplicably.

Has anyone got any suggestions as to what is happening, why, and if there is a way of retrieving the emails? Thanks.

I have just had my Thunderbird account downloaded to a new computer. The previous set up on my desk top was faulty. There are still some corrupted emails (OK) but I can't delete anything using the dustbin icon and the system cant access the deleted file.

I'm getting "server authenticated but not connected since thunderbird update Version 128.3.2esr connecting to my Microsoft365 account through GoDaddy. Windows 10. I disabled the IPV6 setting which solved the issue in other releases, however the error persists. Any help would be appreciated.

Thunderbird stopped working and crashes at startup. It fails also in safemode. Any idea?

I am struggling to increase the very small text size viewed in both send/receive emails ... I am guessing the view size is no more that point 6. All other screen text is good and my composition texts are set at 14. Reading various posts has not resolved my problem eg https://support.mozilla.org/en-US/questions/1442091

I know that I can adjust view per email but there must be a global setting. Any help appreciated.

How to change hover color in New Email Windows for email address link for screenshots: Screenshot

Thunderbird version 128.3.1 In the new message window when I move my cursor over the email address list my Windows titlebar orange color shows up as half transparent. When I click on an address it uses my light blue color I use in the main window for hover and selected. #52aaff

Question: How to change the hover color in the new email window to match what I have in the main window?

In the main window the hover and selected color solution is this in my: userChrome.css file.:

/* Folder Pane - hover color, once a row is clicked on it will either display the Windows Titlebar color you choose if you do not specify a color here then the hover color will continue on any other row you hover over. light blue specified */

.container:hover {

 background-color: #52aaff !important;
 border: 0px solid #000000 !important;}

/* Folder Pane - light blue specified */ li.selected > .container {

 color: black !important;
 background-color: #52aaff !important;
 border: 0px solid #000000 !important;}

My email was working earlier today. Now - WHENEVER I click on "get mail" is does NOTHING. No messages at the bottom saying "retrieving" etc. I completely ignores the request.

 1) I turned of Norton - no change.
 2) I restarted computer - no change.
 3) I tried a different email client (browser based) - works fine.
 4) I am not running a VPN (verified by ISP call).
 5) ISP says "it's on your end (your client is the problem)".
 6) I reinstalled latest version - no change.

 What's next?  Thanks for any help you can provide/suggest.  If replying by email please send to

jimbetz@jimbetz.com and not this gmail account (never use it).

I am using Thunderbird on Windows 11 and I have foolishly allowed it to update itself to release 128.1.0.esr without checking the bug reports first. Now it turns out that this release removed the possibility to search the calendar for past events, which is absolutely essential for me. There is a Bugzilla entry for this but it is bogged down in discussions about who needs which date ranges to search in and how many instances to show for recurring events, so I don't expect a solution any time soon. How can I revert Thunderbird to the last release which still has that functionality? I have regular backups of my userprofile folder in case it helps.

I am using the latest version of Thunderbird 128.3.3esr 64-bit on my Windows 11 Laptop.

I have just discovered to my dismay that I am no longer sending Return Receipts to my received emails. I know that in the past that I always did! My Global Settings for Return Receipts have not changed. Any suggestions or advice would be much appreciated.

I was trying to create a unified folder for all my 10 different email addresses to display the messages received today. I couldn't figure out how to create one, so I set the criteria in the Templates Unified Folder and then I renamed that folder to "Today's Inbox". As soon as I hit ok, it disappeared, never to be seen again. So now, I don't have my Templates Unified folder, which I never used, nor do I have the Today's Inbox Unified Folder. So how do I create a Unified folder?

Installed latest version of TB and want to migrate account settings and messages from Postbox to Thunderbird. I used the TB import tool and selected the active Postbox profile to import. All three accounts were imported. All the emails in one account were imported. In the case of the other two accounts, one of which is active and one is inactive, TB only imported the message headers only, not the contents.

I then found a migration app from a software company that was supposedly designed specifically to migrate Postbox accounts and messages to TB. When I ran the app, I got the exact same results as when I did it manually.

Any ideas on why the message content is missing on all emails in the two other accounts? The account settings are unchanged from Postbox.

Thanks!
