Thunderbird Community Forum

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.

In Thunderbird's Settings under "Language & fonts, Choose the languages used to display menus, messages, and notifications from Thunderbird" I have selected Danish and English. Now I would like to remove English, because my folder pane is displayed in English, even though I have selected Danish as the first language (I am from Denmark). But I cannot remove English in Settings, only move Danish or English up or down. I cannot click on the Remove check mark, neither for Danish nor English. Does anyone know why?

I have an email account with BlueHost, which also hosts my web domain. A couple weeks ago I stopped receiving emails and contacted BlueHost tech support. The agent had no clue why I wasn't receiving email. She said "Can you please click on acocunt actions and remove the account and re-addd it. [sic]" I did that, and I was again able to receive emails. But then all my old emails -- sent and received -- had disappeared. BlueHost was able to restore my Inbox emails back to May 19, but was not able to recover any Sent emails. I have a backup of my Thunderbird directory from April, but would like to recover all of my old emails, which apparently still exist because my current Thunderbird Profiles directory contains files corresponding to deleted email folders. For example, my Inbox had a subfolder -- call it ABC -- that was deleted and is no longer visible in my Inbox, but I can find files ABC (no extension) and ABC.msf in my Inbox.sbd folder. My Sent.sbd folder also contains files ABC and ABC.msf. These folders are in C:\Users\aaa\AppData\Roaming\Thunderbird\Profiles\aaa.default\Mail\mail.aaa.com (with "aaa" representing my personal identifiers). mail.aaa.com contains files Inbox, Inbox.msf, Sent, and Sent.msf, which seem to contain my old emails. (Inbox is 132,151 KB and Sent is 289,829 KB, and the file dates are from a couple weeks ago, when I removed and re-added the email account.)

Is there a way that I can recover the old emails?

I am trying to install an add-on to enable the transfer of large email attachments but, having tried to install a "selected" Filelink add-on, I receive a message that it cannot be installed as it is not validated by Mozilla. Please advise which add-on is accepted. Thank you.

I want each email I receive on a separate line in my inbox. Currently emails from the same address are being kept in the same location in the inbox. I have tried to uncheck threading but this does not help. This behavior results in my not seeing a new email from the same address as the previous ones which are still in my inbox.

I am trying to install Thunderbird on a computer with windows 10 pro but install gives a message cannot install require a minimum of windows 10 but I do have that. what can I do please. Regards Neil.

Why is this folder SO LARGE !!! C:\Users\xxxx\AppData\Roaming\Thunderbird\Profiles\6v2ccsvd.default-release\ImapMail

On my PC, it is over 3.5GB !

How can I minimize it !

I have a lot (96, to be exact) of filters set up to send most emails to a particular folder. I recently had to change the name of my incoming IMAP server, and now all of my filters don't work. I get an error message when an email comes in that should be handled by a filter, the email is left in my Inbox, and that filter is set to Disabled. I then have to edit it and re-select the destination folder and re-enable it. What's going on here? Is there a way to fix this, short of manually editing each of the 96 filters?

I don't see this addressed recently and the fixes from previous versions don't work. Using Thunderbird 140.5.0esr (64-bit) on Mac OS Monterey 12.7.6. Since T-bird updated I have not been able to change font colors or highlight font any outgoing email and I can't see colors in my incoming emails. I can copy and paste incoming emails into a word document and the color formatting shows up. If I write an email in a word document, change the color then copy and paste this into an outgoing email it reverts to black font. I can change bold/italic/underline.

I disabled my two extensions and tried again - no change either sending or viewing received colors

Under Settings > Composition > HTML Style "Use reader’s default colors" is checked and under > Sending Style "Both HTML and Plain Text" are checked

I'm missing something here but can't figure it out!

My e-mail provider has done the annual update of security and provided a new e-mail cert; however, Thunderbird no longer successfully updates it.

Thunderbid gets to the point of confirming the security exception; however, does not proceed.

This is using ThunderBird 140.4.0esr (64-bit) from Ubuntu Snap, on Ubuntu LTS 24.04.3.

I get this message when I email to people on Yahoo, comast.net and others. MAILER-DAEMON <postmaster@earthlink-vadesecure.net> yesterday

Hi, I use Firefox and would like to migrate over from Gmail to Thunderbird. I'm getting fedd up with Google trying to overpower me with everything.

Q1, if I download and install T/Bird will it run my gmail and icloud emails

Q2, will I have to e mail everyone to say not to use Gmail, they must now address me at T/Bird?

Q3, How easy is it to empower T/Bird to control my 2 mail accounts?

Cheers,

Colin

I can't send Free-online emails on Thunderbird/Macbook, although I can receive them (see Error notification attached). I checked the Outgoing server settings in the Accounts settings which seem right (relay.free-online.net). This has been happening for about a week. Thanks for your help.

Hi, I am Div, and I have a large number of EML files which I want to send to Thunderbird. Can anyone tell me the best ways?? I know the manual method, but it didn't work out for me because I want my files to be imported safely in bulk, as it is my daily work. I want a reliable solution. Will be really thankful if someone suggests a safe and quick solution.

Hi

I am using the latest TB build, 144.0.1and have only the British dictionary as an extension, no themes.

Occasionally TB will hang when launched and the Windows event viewer will show this....(added image)_

The friendly xml log within the event viewer...

AppName thunderbird.exe

 AppVersion 144.0.1.0 
 ProcessId 0x6234 
 StartTime 0x1dc51956edcf231 
 TerminationTime 5 
 ExeFileName C:\Program Files\Mozilla Thunderbird\thunderbird.exe 
 ReportId f3ad169f-c629-4357-85ae-7db29d0541f1 
 PackageFullName  
 PackageRelativeAppId  

HangType Cross-process

as noted, this only happens when the email client is launched and will not happen each time. I have tried without the dictionary, as it is so random it can take a while to occur, but that does not seem to make a difference.

I am using Windows 11 25h2

Thanks

Email problem. Old Lenovo Desktop, Window 8.0 (I know, I know, but it's my wife's and all she uses it for is email and utube recipes, and she's used to it). I use it for some banking, mainly because the printer is on it. Tbird 115.18.0 (32 bit) -says it's up to date AVG antivirus free

Email through yahoo. It worked fine until, going by the last date it linked email, 10/30/25 at 06:45AM MST When I tried to download new messages Sunday 11/2, it failed.

It pops up a new window "Enter credentials for bababarb@yahoo.com on imap.mail.yahoo.com" In the address window is "https://login.yahoo.com/?src=thunderbird&client_id=(about a zillion characters) Then, in the message window is "Edge: Too many requests"

So, I did the troubleshooting as in Help article. I logged in on the webmail, signed in with the password, and was able to see the messages, many from after the 30th (she gets a ton of sorta spam).

Looking under Account setting> server settings, I find that the security is set to SSL/TLS and Authentication is set to OAuth2. Incidentally, these were set automatically when I set this to a yahoo.com address.

So, I try setting the Authentication to Password and request mail. I get a popup asking for the password. I enter it (the same password I used on webmail) and it replies "Login to server imap.mail.yahoo.com with username bababarb@yahoo.com failed."

Following suggestions on the help article, I got to Settings, and check "saved passwords". Then, again following the suggestions, I remove the yahoo password entry. According to the article, the next login attempt should ask for a password. It does not. I just get the "too many requests" popup. What the hell, I go back and remove the SMTP password, too. Same result.

Anybody else having this issue? Any suggestions?
