After new installation I want to use my profile of the former installation. In principle I followed the procedure of the article "An einem anderen Ort wiederherstellen". After that when starting thunderbird it always asks me to create a new account.

Does anyone know what is missing?

bonjour, depuis quelques jours il m'est impossible d'attacher une pièce jointe à mes envois de message avec THUNDERBIRD... bouton "joindre" inopérant.. bug constaté sur mes deux ordinateurs (bureau et portable) équipés de: - Windows 11 - Thunderbird 157.0.1 Merci Cordialement Jean

Bonjour, A la maison, je suis sur iMac M4, pour le sérieux et sous Linux Mint pour respirer dans le monde du libre. Sur Mon iMac,j'ai bien la dernière version d'installée: 153.04.0 esr

Sur ma messagerie Thunderbird, je n'arrive par à joindre un fichier (PJ) dans un message départ. - Quand je clic sur "Ajouter une pièce jointe", aucune fenêtre ne s'ouvre (Finder)

Quand je suis sous Linux, tout fonctionne bien.

Cordialement

I'm using Thunderbird on Ubuntu 24 and have some messages in some mailboxes that have lost their headers. I'm trying to fix them.

Early (1980's command line mail & mailx) mbox files were pure text with messages delimited by a blank line followed by a line starting with 'From ' (or possibly 'From: '). When I open a Thunderbird mbox file in 'vi' it is 'converted', or so it says. I'm wondering what this 'conversion' is and why it's needed.

Please could someone tell me what the strict rule that delimits messages in a Thunderbird mbox file is, and what is it that 'vi' cannot handle that requires 'conversion'?

Thanks

Dear Thunderbird Support Team,

We are experiencing a problem with the attachment feature in Thunderbird following a recent system update on our computer.

Since the update, the Attach option in emails no longer works, preventing us from attaching files to our outgoing messages. We use this feature very frequently in our daily work, as we regularly send documents by email, so this issue is causing significant difficulties for us.

Could you please help us resolve this problem? We would appreciate any guidance or troubleshooting steps you could provide.

Thank you in advance for your time and assistance. We look forward to hearing from you.

Kind regards, Exterra

I no longer have a right click menu available for photos in an email. There is only the option to zoom in or back out. My screen does not match what directions Google has to offer to fix the bug.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

Hi Despite I make reminders (I get the bell symbol for the event) for events in calendar, I don't receive alarms any more. If I have Thunderbird open at the time for the alarm, I might get an alarm. If I then postpone the event I don't receive the new alarm. I have had Thunderbird and calendar for several years and it has worked without any problems, I would receive alarms occured for the time I didn't have Thunderbird open, when I opened Thunderbird. I did get the alarms, also when I postponed an event. But for long it hasn't worked. I can't rely on the calendar not receiving alarms/reminders. I have tried to delete/remove Thunderbird and install again, that didn't help. I hope someone can help me, please. Answers in Danish are welcome. Best Joyanna

I'm not sure how to make a feature request, but here is one. Can it be made easier to sort message filters alphabetically? I currently have over two hundred of them, because each site I sign up for gets a unique email alias, and I set up associated filters for them (each goes into a dedicated folder in my Inbox). It's a pain to manually sort them in the list.

Hello,

I urgently need technical assistance with a serious issue involving Mozilla Thunderbird and my professional certified email account (Aruba PEC, Italy).

I have been using Thunderbird to manage my professional email correspondence for several years.

I organize processed emails into yearly folders (2024, 2025, 2026, etc.), located under my email account in Thunderbird, not under Local Folders.

Today, October 13, 2026, I discovered that all emails dated January through September 2026 have disappeared from my "2026" folder.

Only emails from October 2026 remain.

The missing messages include professional correspondence, certified email delivery receipts, acceptance receipts, and potentially legally significant communications.

What I have verified so far:

The "2026" folder exists both in Thunderbird and in Aruba Webmail.

Both display the same remaining emails from October.

The Trash folder is empty.

The 2024 and 2025 folders still contain their messages.

Thunderbird's retention settings are configured to "Don't delete any messages."

The "2026" folder inherits the account's retention settings.

I did not knowingly delete or move these messages.

Aruba customer support informed me that they cannot restore the missing emails.

I checked Windows Previous Versions and OneDrive, but no backup was found.

I located the local Thunderbird mailbox file named "2026" in the profile's ImapMail directory. It is approximately 3 MB.

Inspection of a copy of this file did not reveal message headers from before October 2026.

I could not find another larger copy of this mailbox file in the Thunderbird profile.

I occasionally remove unused folders under "Local Folders", but I do not recall deleting any folder containing these messages. The affected "2026" folder is located under the IMAP email account.

My questions are:

Could Thunderbird have deleted or moved these messages automatically despite the retention settings?

Could IMAP synchronization, folder corruption, message filters, or compaction explain this situation?

Are there any additional Thunderbird files, caches, databases, or recovery methods worth investigating?

Is there any way to identify when or how the messages were deleted?

What steps should I take to prevent further data loss?

I have preserved a backup copy of my Thunderbird profile and would prefer not to perform potentially destructive operations.

This is particularly serious because the missing messages are part of my professional and legally relevant correspondence.

Any technical guidance would be greatly appreciated.

Thank you very much for your help.

Hi I have four IMAP email accounts configured in Thunderbird. Three get email from my servers the fourth from Google mail.

I am finding that one of the accounts emails are also ending up in Google mail, the other two are functioning normally.

I have checked for email forwarding etc and cannot find anything.

I removed the account, leaving the Gmail account alone, from my mobile and the phenomenon stops till I fire up the PC.

Anyone got any ideas?

Since yesterdayevening I am experiencing problems with connecting to imap.one.com with all four of my accounts in Thunderbird 157.0.1 (64-bits). It says something like "Connecting to the server at imap.one.com with username XX@XX.XX failed" (translated to English) Mailsystem at one.com (webmail) and in my Android (Bluemail-app) works fine. I tried to fill in the right passwords, even changed a password and tried the new one, but still no effect.

Settings: Servertype: POP-mailserver Servername: imap.one.com Port: 995 Username: emailadress

Connectionsecurity SSL/TLS Authenticationmetod: Normal password

I use the release-update-channel (if that is usefull info?)

What can be wrong?

Hello! I'm having a problem where a specific tag keeps un-applying itself. I have a number of filters that look for specific words in emails, and tag them accordingly -- all of my other filters are working just fine, but one specific one has decided to stop working. It has exactly the same settings as the other ones, and when I manually run the filter, it correctly applies the right tag.

But, minutes later, the tag will un-apply itself, and I cannot figure out why. For some reason, an older message is staying correctly tagged with that filter, but newer ones un-apply the tag. This same filter and tag used to work just fine. Other tags on emails from the same source work fine, too.

Hi, my mozilla has just stopped dowloading messages to my laptop. Oddly, any messages sent seem to be received, and a test to my phone to myself verifies. Any suggestions please I would be most grateful for!

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.

I have 5 Gmail accounts they r all configured the same I automatically let thunderbird install two but none of the other three will not connect i have tried everything i can think of but to no avail
