Cannot insert underlined hyperlink nor clipart into email using version 138.0 64 bit

Thunderbird makes it so difficult to fix settings anymore.

The config editor is a mess and unbelievable to understand what options are available and how to use them for anything speicifc.

Whenever a new message is received, which should go to the Local Folders\Inbox, instead a previous email from 2 days ago is always shown. I have recreated new emply Inbox and Inbox.msf files, but to no effect. Any suggestions on how to fix this?

Hello Team Thunderbird You are doing a great job. I use thunderbird regularly.

I wish to contribute through donations.

Can you have UPI payment option in India? I will be donating regularly with that option.

Yours Sincerely

Hi,

I'm experiencing issues with threaded view in Thunderbird (version 139.0.2 on Windows). Some threads do not display all messages -only a few emails are shown (e.g. 2 out of 8), and others are missing from the thread view even though they are present on the server. Rightclicking a message and selecting "Open message in new tab" sometimes works (but still doesn't show all messages), and sometimes it doesn't open a new tab at all. the missing messages do exist on the server, and I can find them using Ctrl + Shift + F , but they do not show up in the thread, nor do they appear via Global Search, even though the global index has finished building.

I have tried the following: -Right-click folder > Properties > Repair folder -Deleted and rebuilt global-messages-db.sqlite (global search database) -Reduced IMAP mailbox size from 140GB to 110GB -Waited for reindexing to complete

But the problem persists. It seems that Thunderbird either doesn’t associate all related messages with the same thread, or skips them entirely in display and search.

What can i do to fix it? Thanks in advance

Hi all

I have my sent mail going into my Inbox be default, so that I can see entire threads in context. It's set that way in Copies & Folders in each of my email accounts. However, I frequently find sent emails in the Sent Mail folder.

Can anyone offer an idea of why, and how to fix it?

Thanks Edwin

When I downloaded the Thunderbird app to my new laptop and opened it, it already had a fortnight's worth of recent messages in the Inbox, plus many of my Sent messages. However, the remainder of the Inbox, dating back to 2010, was not there, neither were my address books. Why didn't a clean copy of the app download so I can import my Profiles? In addition, my old laptop uses POP incoming, but the new laptop seems to be configured to IMAP. Is this a problem, and if so, which should I choose for the new laptop?

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

Hello everyone,

I recently saw Mozilla announce that the Pocket service will be discontinued on July 8, 2025, entering an export-only mode, with user data permanently deleted after October 8, 2025.

I’m very concerned about its future. The shutdown of Pocket really hit hard, and it makes me worry: could Thunderbird face a similar fate? Especially now that Mozilla seems to be focusing its efforts more on Firefox and AI browser development, I’d like to ask the community and official team a few questions:

1. What is the current organizational structure around Thunderbird’s development and maintenance? I understand that since 2020, Thunderbird has been placed under MZLA Technologies—an independent, wholly‑owned subsidiary of the Mozilla Foundation—and is managed by the Thunderbird Council. Does this mean Thunderbird operates under a fundamentally different model from Pocket?

2. Is there any possibility of Thunderbird being discontinued, divested, or “down‑scaled” in the future? Does Mozilla have any plans to shrink Thunderbird or shift strategy in a way similar to Pocket?

3. What is Thunderbird’s planned roadmap and how are resources being allocated? From what I’ve seen, Thunderbird is undergoing UI redevelopment (Supernova), monthly releases, mobile client initiatives, and new Pro services like Thundermail, Appointment, and Send. Does this reflect Mozilla’s confidence in its future?

4. How can users and community members show support or express concerns? If we want to help ensure Thunderbird’s continued health and growth, what steps can we take to encourage Mozilla to allocate more resources?

When I search Messages (Ctrl+Shift+F) there used to be an option to select "Body" Contains [a text string]. But it's disappeared. The body of my emails IS downloaded and 'Keep messages in all folders for this account on this computer' IS checked in the Sync. and Storage section of Tools/Account Settings. So how can I get the ability to search the body back?

Tag names can be changed via message > tag > manage tags. But how can I change the tag ID ?

Let's say for example, I want to change the tag ID "unreplied" to "needsreply".

steps:

1. in user.js: change user_pref("mailnews.tags.unreplied.tag", "unreplied"); to user_pref("mailnews.tags.needsreply.tag", "needsreply");


2. search&replace all instances of regexp ^X-Mozilla-Keys:[^\r\n]+unreplied in all .eml files


3. Some tags are not stored as "X-Mozilla-Keys" inside the .eml file but elsewhere ( https://forums.mozillazine.org/viewtopic.php?t=3123346 ). How can I replace "unreplied" with "needsreply" there? (If I don't do this, messages previously tagged as "unreplied" won't have the "needsreply" tag after step 1.)

Hi, I am feeling pretty stupid, as I have been using Thunderbird for years on my PC. Now, on my laptop I can't find where to compose a new email. The new email button is not anywhere to be found, and up until today there was something that I could click on to "create a new email" in the top RH corner, but that is gone as well.

HELP

thanks in advance Graeme

when i oppened tbird on windows 10, it showed a page to obly my for a donation. i had made a donation short ago, but eventhough, i just made another one time donation. when i open tbird again, i can not get out of the donation page. what should i do please???????

Not sure what has changed, but I have a lot of sub-folders in my email handler, I've set up filters and generally, the incoming mail get through the filters and ends up in the correct sub-folders, but today, I've been trying to add one sub and it fails. No message, no error. Just no sub-folder creation. Did an update do this to me? And others?

My desktop computer died, so I needed to copy all my data files from backup (which worked fine) and then install all the apps that I regularly run on my laptop. When I installed Thunderbird, I got the latest Release 139.02. It behaves very differently from what I think is called the "Classic View" that was running on my Desktop. I REALLY hate it, but can't figure out how to set the Thunderbird parameters to do that. My problems include:

-- Overview of Thunderbird "Views". I can't find any documentation that explains [a] the various viewing options that Thunderbird offers and [b] EXACTLY how to set them.

-- Release Notes. I haven't found any release notes to explain when/why a major change to view was done.

-- Periodically, even for same release, Thunderbird CHANGES my parameter settings. Most annoying is changing the General Message-List settings to "Show Only Display Names For People in My Address Book". I live in a retirement community where many husbands & wives share the same Email address. With this setting, Thunderbird shows the name associate with the first message I received from this Email address. So the heading doesn't show which person actually sent it (although I can make a good guess when Thunderbird is telling me it came from a dead person. [g]

Is there ANY way I can get Release 139.0.2 to display messages the way I've been seeing them for at least 10 years? I REALLY need help. (If I can't get Thunderbird to behave the way I want, seem like I might as well switch to reading/writing messages directly from Google Gmail web site. It's equally lacking in documentation, but I suppose that eventually I could figure it out.)

Thanks in advance for any help anybody can offer.GMail, I'd seriously consider switch to using Gmail directly without Thunderbird.)

I have an 8 year old PC that I have been using Thunderbird on its entire life. I have 5 email accounts (from my own website if that matters) on it for personal use that have tons of information.

I bought a new computer and have not been able to move my old data to it. The old computer uses Windows 10 with Thunderbird Version 115.5.2 (32 bit). The new computer uses Windows 11 and I have tried several Thunderbird versions with the current one being 128.12 0esr (32 bit). I have added one of my email accounts to my new computer, but it contains none of my previous data (emails, contacts, directories, etc.), just a bare bones account that only receives new email.

I have repeatedly tried to move my entire source computer setup and data going through all of the described steps including copying the previous Thunderbird folder to a flash drive. I then follow the directions for copying and pasting my source data into the new computer's "roaming" section. It goes through all the steps including asking if I want to overwrite existing files. I have almost 14,000 files and as the process continues, I can see file names being added just as I would expect.

After everything is complete, when I restart Thunderbird, the only access I have is once again to the bare bones new email account. There is no data, nothing at all, from my source computer.

Help please, this has gotten beyond frustrating.

Ich kann keine Nachrichten mehr erhalten und und kann auch nichts mehr absenden. Es wird immer wieder ein Passwort bzw. neues Passwort verlangt, das war all die Jahre nicht. Auch ein Passwort wird nicht angenommen. Hab schon alles ausprobiert.

I'm aware of the many caveats regarding use of 'Repair Folder'. It's widely known that the results are...inconsistent, to put it charitably. Nevertheless...

I keep vast quantities of messages in local folders. For some of those folders, I manually archive the contents annually, by creating a new folder with the name of the year ("2025"), then dragging messages from the existing folder to the new folder. This sometimes works. More often than not though, it fails in one way or another. Sometimes I drag them across, a handful of them show up in the new folder, but then the rest just sit there in the old folder, in selected state, but with no activity taking place. Sometimes merely selecting smaller 'chunks' of messages to drag across will work. In others, such as last night, even that didn't work.

I then invoked 'Repair Folder' in a vain attempt at recovery; sometimes that will clear the issue. However, when I did this, what happened is that the chunk of messages that were selected wound up having all their date fields (in the display) reset to near the epoch - January 20, 1970. When I view the message source, the dates are correct.

I'm unable to find a way to recover from this.

Any advice would be appreciated.

Hi everyone.

Hoping someone may be able to help. I see that other users are able to fully highlight the events in calendar. I seem to be only able to highlight 2/3's (see image)

Thanks in advance
