Thunderbird Community Forum

People are not receiving my emails. I am receiving other peoples emails. I am using Linux Mint 22 and Thunderbird 140.11.1esr. If I send an email and look in the sent folder, it shows that it has been sent. If I log into my Bell Webmail portal and check the sent folder there, it shows that the email has been sent. But no one gets my emails. If I send an email from my Bell Webmail portal, people receive that email. I have re-installed Thunderbird and allowed Thunderbird to autofil the incoming and outgoing server information after entering my user name and password. No change. I have contacted Bell my internet provider and they have told me that because I can send from the Webmail portal and not from my Desktop, it is a Thunderbird problem. It seems that this problem may have start just after Thunderbird received an update about 2-4 weeks ago. It has been around a month since the last time I had a back and forth email exchange. Searching the forum has been difficult to find an issue similar to mine. Any help would be appreciated. Robert

I am trying to set up my t-online.de account on Thunderbird, so far without success. A message appears: Thunderbird failed to find the settings for your email account. I don't know where I am going wrong.

None of your "topics" addresses my issue at all. Where is your user manual? I'm trying to figure out how your "retention" works. Also how to get a message filter to run on a specific folder daily.

Thanks, Saroj Gilbert

I had a great Thunderbird Emoji add-on that is no longer supported. This.

https://services.addons.thunderbird.net/en-US/thunderbird/addon/emojiaddin/

It no longer works on updated Thunderbird, and shows it hasn't been updated since 2022. I'm on Thunderbird 140.11 on my Linux Mint. The image the plugin inserts in message bodies is broken. Is there another/similar add-on?

Hello, I use Thunderbird to manage several email accounts, one on them is not active anymore but I still want to be able to access the emails stored in my thunderbird directory tree, so I keep it active. And the fact is that every day this account tries to access a remote server that does not exists anymore to retrieve email that can not be retrieve, and every day I am asked for a password that cannot work. But the fact is that I did deactivate all options to read remote emails for this account, so that behavior is odd and I am not able to find a way around it. Any idea what to do not to be bother anymore ?

Thanks in advance for your help :-)

I've successfully connected to a hosted Exchange server through EWS and NTLM authentication (kudos BTW). But there is a problem - often during operations against EWS I'm presented with "Login to account XXX failed" "Login to server YYY with account XXX failed". I can ignore it (cancel) and it will work for seconds or minutes but eventually reappear. Sometimes it's very frequent, sometimes is here and there. TL;DR; connection works, I can read directories and e-mails.

From looking at development tools I see these scenarios: 1. POST requests return 200 always (no messsage of course) 2. Eventually a POST would return 401. Then Thunderbird issues a GET, it returns 401 as well but response includes header WWW-Authenticate: NTLM XXXXXX. Then another GET is issued containing header "Authorization" with the value from previous response. This time it gets 200 and continues without POST requests without a dialog. 3. Sometimes there are more POST requests with 401 (I assume in parallel) before a GET is issued and then I see a dialog. Sometimes it recovers (regardless of whether I cancel or retry), sometimes gets stuck with 401 with dialog reappearing each time it tries something. This case it's similar in sense that thunderbird issues GET with 401 and WWW-Authenticate header, issues another GET with Authenticate header but still gets 401.

If I had to guess I'd say the problem happens when POST requests are issued in parallel, not sequentially. OTOH it might be a problem at the server, but it isn't very likely.

I use Thunderbird 140.11.1esr with Ubuntu 24.04. I also use LibreOffice 26.2.

When using LibreOffice, if I want to delete a number of contiguous characters, I put the cursor at the start of the characters I want to delete, press the delete key and hold it. Holding down the delete key means that delete works its way through all the characters I want to delete.

When using Thunderbird, if I want to delete a number of emails, pressing down and holding the delete key doesn't result in the deletion of a number of emails. Instead, I have to keep pressing delete again and again.

Is there some setting in Thunderbird that I can change that will result in delete automatically working its way through all the emails I want to delete?

Thanks,

Leslie

I have been using Thunderbird calendar synced to gmail a/c on Linux Mint for many years and have been able to send reminder notifications by email. Recently I had to unsubscribe my calendar and reinstall to clear a fault and the notification by email function has disappeared from Thunderbird event notifications. Can you tell me how to restore that function?

Version 140.11.1esr

My Yahoo account on Thunderbird sees no email found.

My eMail Providers: Yahoo, AOL, Gmail.

AOL and Gmail(2 accounts) work fine. Only Yahoo doesn't respond. As you can see in the attached screen shot, it shows a "No Messages Found" message.

I have tried everything listed in the support page.

I'm sure it is something simple but I can't see it.

To get some information out of the way before reading: my verbose step-by-step is listed below, followed by a summary without the trouble shooting steps. I have read the information about managing profiles when running multiple release channels, but found it a little confusing. If I can improve the formatting here, please let me know and I will edit my post to be more clear.

I am leaving the troubleshooting steps in the event that I did something wrong here.

My questions are primarily: 1. is there a more straightforward way to do this? 2. are there any additional steps to follow after successfully getting both a Release channel installation and a Beta channel installation as far as profile management?

The problem, with step-by-step troubleshooting steps to solve I have Thunderbird Release installed on Linux Mint system-wide, following the instructions here: https://support.mozilla.org/en-US/kb/installing-thunderbird-linux#w_system-thunderbird-installation

Now I take note of the fact that beta must be installed in a different directory: "It is possible to have multiple channels of Thunderbird installed, and even run them simultaneously. Each must be installed in a different installation directory, which will force multiple Thunderbird data profiles to be used in order to protect and keep your data separated."

• ...so although I have an `/opt/thunderbird/` directory, I rename the downloaded extracted tarball `thunderbird-beta/` and move that directory to `/opt`

I move on to Step 4 from the article linked, creating a symlink.

• what I used to install Release: `sudo ln -s /opt/thunderbird/thunderbird /usr/local/bin/thunderbird`
• what I used today to install Beta: `sudo ln -s /opt/thunderbird-beta/thunderbird /usr/local/bin/thunderbird-beta`

Everything works from here as far as me being able to click on the `thunderbird-beta` executable in `/usr/local/bin` and get into the Beta application with a fresh program.

Here is the step I'm unsure of, and where I run into issues.

In Step 5 of the linked article, when I installed release: "Download a copy of the desktop file": `wget https://raw.githubusercontent.com/mozilla/sumo-kb/main/installing-thunderbird-linux/thunderbird.desktop -P /usr/local/share/applications`

...gives me a launcher in `/usr/local/share/applications`. I can edit this in a text editor to point to a different icon etc if need be, but when installing release this is obviously already configured.

So when I install beta, I don't want two of the same icons representing different Thunderbird channels, because my assumption is that will cause issues. So instead of downloading this file again, I copy the file I downloaded with `wget` when installing release, and instead of naming it `thunderbird.desktop` I name it `thunderbird-beta.desktop`

• I then edit this file in a text editor to point to the Beta icon in `/opt/thunderbird-beta/chrome/icons/default/default256.png`
• But the resulting file indicates "there was a problem launching the application" and when reopening the file in a text editor, I notice none of my changes have persisted and it's blank.

...I can confirm through a file manager that the icon at `/opt/thunderbird-beta/chrome/icons/default` is a visually different icon with "Beta" added to the bottom of the icon.

So this launcher in `/usr/local/share/applications` is the step I'm having trouble with.

Troubleshooting steps:

• I delete the previously edited `thunderbird-beta.desktop` file, and I rerun the `wget` command to download another copy of `thunderbird.desktop`, this time using the `-o` flag so that the resulting name is `thunderbird-beta.desktop` again. I again edit this with a text editor and point the icon field to `/opt/thunderbird-beta/chrome/icons/default/default256.png`

For some reason, this works: allows me to save my changes and the icon of `thunderbird-beta.desktop` successfully changes to the Beta icon. By default, with no other changes, clicking this successfully launches Thunderbird, but of course it launches my Release version, so I change the Exec parameter to point to the Beta executable in `/usr/local/bin`

And now I get my desired results: start menu entry, separate icon, and launching the Beta release.

So my primary questions again are: 1. I notice that simply running the Beta application once uses the same `.thunderbird` directory that Release uses, and creates its own profile folder, which seems ideal to me. Verifying that this is the expected and preferred behavior? 2. I'm confused about the support article for profile management when running multiple release channels. Do I want to re-add all of my accounts to Beta from inside the application, therefore having two copies of my mail and profiles on my computer?

An address book that I was using for years suddenly stopped working. It was called 'nachbarn'. I had to rename it to 'nachbarn@here', and it worked again. This is on Linux, and a week ago I have been using this list with its old name. But in betwen I changed my account from POP3 to IMAP, which may have contributed. Since there are plenty of complaints on the Internet, I'd suggest to change the plausi check for the address field, so that the address must either contain an '@' or be the name of a list or address book?

Thanks a lot!

My email provider provides "Disposable Email Addresses" - aliases which still direct mail to my inbox but don't expose my primary email to any web sites etc. I provide them to. It's very handy for registering for mailing lists, product vendors etc. since if one gets leaked, it's no big deal. I can drop the email again, but at least I know who was responsible for leaking it (I still get spam to my old Myspace account). My problem is that I'll occasionally have a need to reply such an email, and by default my From: address is my primary email address, not the one in the To: header. This is confusing to the recipient (since it's from some unknown email) and also exposes my email unintentionally. Is there any way to configure Thunderbird to always reply using the To: address? If there are multiple To: or CC: addresses, it could perhaps be specified with a wildcard matching any of my aliases. I can do it with Identities, I know, but I have to set that up before replying and I frequently forget.

Hi, I can receive emails (via satellite internet) but not send. I logged on to my email provider and I can send emails from there but not from here. any ideas?????

I'm reading the question Thread's broken sorting makes it completely unusable and I have to agree that order of messages within thread is not the best one - ascending. For example, I am subscribed to a forum messages and I'm getting all the notifications for a topic to a thread. Currently I have like 85 messages in a thread and to see the newest one I have to scroll all the way down each time - scrolling 85 messages is a lot and it is getting worse because the number of messages keeps growing. After I've seen the newest message, I have to scroll all the way up to close the thread. (or am I missing something - perhaps some shortcuts?)

But I guess for some such ordering is obviously fine. Hence, I guess, an option how to sort threads might come handy. Perhaps even having a default sort order and an override per thread?

PS. funnily enough, I'll have the same issue with notifications for this question :)

I use Thunderbird on dark mode, so by default, unformatted text (where I haven't explicitly set text color) appears as white text on a black background in my compose window. The same unformatted text, when sent to someone viewing it in light mode, appears as black on white to them and remains readable. When I use white text in my compose window, it looks identical to me, but remains white when sent and is thus unreadable white-on-white to those using light mode. Is there something in the composition window that indicates whether I'm typing with formatted or unformatted text? (No, the color selector tool does not do this. When typing unformatted text, it displays the last selected colors, regardless of whether they are being used.)

If there's no way to distinguish this, could someone please add a UI element for it?

thunderbird refuses to connect with my email account. it says, either the name is wrong or the passwort, or the settings. name and pssword is proofed, so its the settings. where can i find them, and what is to do ?

I use vertical view. Hate threading so that's turned off. I use a medium to large message pane. Recently been having issues with column visibility. Not sure if this is new or whether it's that I've come to a Linux client from a Windows one and there's a setting I missed when I set up the client.

Essentially dragging the column divider doesn't work properly (for me). The columns always seem to auto adjust width. Similarly if I resize the message pane the columns don't remain fixed they auto adjust.

I don't find this helpful. I prefer to set up the columns to display the amount I want/need in subject and From and I truncate the date to simply not display time.

How do I set column widths to remain where I put them? Or is this function now lost.

I recently obtained a digital certificate for use with S/MIME. I followed the process laid out in

https://support.mozilla.org/en-US/kb/instructions-smime-certificate-using-csr

to generate my key pair, create a CSR, submit it to a CA, download the resulting certificate file, and import it into Thunderbird. I also imported the intermediate certificate showed as the issuer for my cert, which in turn appears to be signed by one of the certs trusted by default in Thunderbird.

Having done that, I see the certificate showing up under "your certificates" in the Certificate Manager, with a "not before" date in the past and a "not after" date in the future. So everything appears to look correct, but when I try to send a signed email I get the following error message as a pop-up:

"Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired."

And if I look at the console in developer tools I see:

"mailnews.send: NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgComposeSecure.beginCryptoEncapsulation]

I can't make sense of the error message, since the certificate appears under "your certificates" in the certificate manager, and it does not appear to be expired. Can anyone suggest how to determine the root cause and fix it? Does it matter that the certificate is for a non-default identify I've added for the account in Thunderbird? Does it matter if the "common name" in the certificate doesn't match the "Your Name" field in Thunderbird? Any pointers on what to check would be appreciated.
