I have spent 3 hours trying to figure this out. Nothing works for me.

Authentication always fails yet when I log into Outlook it always works.

I turned off using the new hub and was able to setup my email account but it told me OWL was not active (or something about OWL).

Godaddy is my provider.

What am I not doing correctly?

When I let thunderbird compress the inbox and other folders, the not read flags on all new emails get reset as if I have read all of the new emails. Compressing the inbox and other folders should have no effect on the flags showing a message has not yet been read. That only makes sense. The not read flags getting reset started happening several versions before 145.

Thunderbird Version 140.7.1esr, Build ID 20260123195141 User Agent Mozilla/5.0 (X11; Linux x86_64; rv:140.0) Gecko/20100101 OS Linux 6.1.0-33-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.133-1 (2025-04-10) OS Theme Xfce / Adwaita Application Binary /usr/lib/thunderbird/thunderbird-bin

Having a problem with an ATT POP account. TB stopped getting mail. After a minute and a half or so (wish it would time-out faster), I get a pop-up box in the top right of the screen that states: "Connection to server inbound.att.net timed out" and then quickly goes away.

Deleted passwords and cannot see where to create them again, as it never prompts me for new ones.

Thanks.

I quite often get this message, though it tends not to be a problem later "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox"

One of the solutions seems to be Compact a File. How do I do this?

Bonjour, Lorsque je me connecte, j'ai un message que me dit : User is authenticated but not connected et ceci sur toutes mes boites mails. De plus, suite à un changement d'ordinateur mes mots de passe sont visibles aves des chiffres et des lettres "1//03csgEnBPtxsaCgYIARAAGAMSNwF-L9IrjQQom22l5sXSkYLP1h4BvsYHGmRYh43NZEdtoe " Je ne peux pas voir mes mots de passe enregistrés Je ne peux donc pas me connecter à mes boites mails car les mots de passe ne sont pas valides A savoir que je suis sur certaines boites mail sur @outlook.com (anciennement dbmail)

Pourriez-vous m'aider à débloquer le problème car je suis très embêtée Par avance merci et bonne soirée PS : Si je supprime l'application et que je l'installe de nouveau, vais-je perdre tout l'historique (dossiers, agendas, contacts, etc ...)

Is there a fix or workaround?

Mozilla, in their infinite wisdom, sent me a note about something new in firefox, by displaying it in a new instance of Firefox.

It wasn’t until I closed my normal session, that I realised a new instance of firefox was also running, and shut it down on.

In shutting the new instance down after my usual session, it overwrote all my normal tab settings🤬

Q1. Are my normal tab settings recoverable? Q2. Why did Mozilla think it a good idea to open a new instance of Firefox to send me information, rather than simply open a new tab.

NB This is in Windows 11

We have been using the Brother MFC-J6940DW iPrint&Scan Attach to email successfully with Thunderbird. It creates a new email and attaches the scanned item to it. Recently it stopped working. Nothing happens and there is no error message. We have run all Windows updates. We have uninstalled and reinstalled the Brother drivers, uninstalled and reinstalled Thunderbird, downgraded Thunderbird to v 143 and 140 from current 144 version. We have confirmed Thunderbird is default mail app and verified in registry that Mozilla Thunderbird is default in HKEY_CURRENT_USER|Software\Clients\mail > (Default) value = Mozilla Thunderbird and HKEY_LOCAL_MACHINEISOFTWARE\Clients\Mail > (Default) Value = Mozilla Thunderbird. We have made sure the Firewall talks nice to the Brother Utilities and the ports are ok for Public and Private. Brother tech support says as long as we can do a normal scan that it must be Thunderbird or Windows. Does anyone have any thoughts or other troubleshooting ideas? Thanks in advance. -- Sue

This is the 3rd time I have had to post this. I am getting very frustrated. I DO NOT want the search engine within my address bar. Nothing anyone from you "community" helped to disable the search engine in my address bar. Opera, Edge, Chrome, the user can disable the search engine in the address bar. Why is Firefox so different? And difficult?

For some time the feature to use color in text has not worked. I deleted and re-installed Thunderbird but no change. I cannot change the font color when typing an email, and making changes in the settings has no effect, either.

I have my "signature" saved as an HTML in color, and it also will only display in black.

Any articles and solutions posted seem to be for people using Macs or some other kind of computer. I have Windows 11 for a Lenovo Idea Pad 5. Thank you in advance for any and all guidance you can offer.

every download gets stopped with "This file contains a virus or malware", have to click on the file, then click "allow download" every time!

I check the file with my antivirus and it finds NOTHING!

Hello everybody, I have 5 accounts managed with Thunderbird. They are named provider, provider-1 up to provider-4. I don't know, which Thunderbird-Account belongs to which Provider-Account. Is there any possibility to find out, which Thunderbird-Account belongs to which Provider-Account and to save one of these 5 Thunderbird-Accounts on disk?

Why did retrieving messages suddenly stop. It was working yesterday and I made no changes to anything. I can send successfully. I am using Shaw/Rogers Pop server.

Why does "test connection to server" fail?

I noticed I cannot log on to amazon.ca or shaw.ca anymore on firefox, why?
