Thunderbird Community Forum

My computer suddenly started the above error message for multiple programs. The local computer shop was able to sort out what appeared to be the root cause and that recovered some things but I still needed to reinstall a number of programs.

The program I am terrified of reinstalling is Thunderbird. All my emails on five email accounts since 2011 are stored in TB and I naturally do not want to lose any of them.

The major problems are the computer is running Win7 Enterprise and I am 82 years old so I am prone to needing things spelt out in greater detail than many others.

Can anyone provide a way to reset the program permissions (preferable) or identify the best way to reinstall and still access all my historic emails?

Thank you

Hi, I have used "takeout" years before but not one of these.

Can I keep folder integrity using one of these? And how if not obvious.

Quota is high.

Thanks

My emails were all working (accounts were setup fine). Then, recently, when I opened Thunderbird, the main area (where my messages are displayed) is empty. If I choose another folder, still empty. BUT, the folders all say that there are messages in them (see the attached screenshot)

I have tried the following... 1. Opening Thunderbird in Troublshooting mode: This works, and the messages appear. But I don't want to have to open troubleshooting mode every time. 2. I have ZERO extensions installed, so asking to disable them obviously wont do anything. 3. I have tried to repair the folders (I have tried to repair the default inbox folder, and then tried to repair them all ... nothing worked). 4. I have backed up my thunderbird files, and tried reinstalling Thunderbird. Still didn't work. 5. I tried these three steps ... https://www.mboxtooutlook.org/blog/thunderbird-inbox-missing-emails.html Didn't work either.

Any other suggestions?

I have an existing account on my old computer. When I put Thunderbird on my new computer, it downloaded thousands of old emails but would not open new mail. I uninstalled and reinstalled and it still won't show new mail.

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?

Hello,

After today's Thunderbird update for Windows 11, over half of the folders in the local folder are no longer displayed. However, the folders are present in the backup folder on an external hard drive.

What's causing this?

Have been trying to set up some pop3 yahoo mail accounts on a new computer. I have used automatic configuration. I have used manual configuration using the data from my old computer. I have checked the configuration settings on both Yahoo and Thunderbird sites. In all instances Thunderbird verifies the account is valid, but the next window asks for my yahoo username and password. I cannot get passed this stage. I have tried entering my yahoo password and I have also tried the app generated password from Yahoo, all I get is a Yahoo "something went wrong" message. Interestingly I did manage to get one of the accounts to work yesterday, but I must have tried no end of different permutations and I have no idea which one eventually worked.

Starting Feb 8, 2026 my yahoo accounts no longer work in Thunderbird. I have accessed these for over a dozen years using Thunderbird. In addition, when I open Thunderbird at all I end up getting endless loops of yahoo login messages. The mechanisms in the messages do not work at all. I have received no Yahoo mail since that date. To troubleshoot the issue I tried logging into the accounts directly through Yahoo. Broken, with no access at all to any help resource from Yahoo. Although Yahoo seems to be keeping mum on the problems, there is spotty information online that Yahoo servers were breached a few days ago. One report claimed that user data for about a billion accounts was compromised. I suppose that may explain why my accounts no longer work anywhere- neither from Yahoo itself nor within Thunderbird. Is there a way to disable the incapacitating yahoo popups pending any larger solution to this?

I use both Gmail and Thunderbird. I can see both in Thunderbird on my PC. I would like to sync my TB address book with Google contacts. I searched a good while on-line and find information about adding a CardDAV Address book. However the instructions mention steps that simply are not available on Thunderbird on my PC. I have the latest version of TB (140.7.1esr (64-bit)). The first step says to "open the Address book, select File>New> CardDAV address book". That is not a choice. Anything in Mozilla support is several years old.

So is this possible or not?

I can't seem to find the way to set or adjust (vertical) line-spacing in the body of the message. The lines "collapse" on each other. (see the attachment) I have unchecked the "Use paragraph format..." checkbox. Can't adjust it with the small / large "T" controls on the formatting bar; and I haven't found any setting (or combination of settings) to control or adjust this attribute. FWIW, it happens both when I paste-in text and when I type-in the text. Suggestions?

I'm presently running TB 147.1esr on a Windows 11 system. I have archived mail by years (2020, 2021, etc.) on an IMAP server and I have defined a Local Folders entry. I want to move some archived years off the server onto the local folders. What is the best way to do this? I searched for documentation, but couldn't find an article on that subject.
