I am unhappy with version 150 of Thunderbird. In earlier versions, I was able to access the full range of emojis when writing an email. That is no longer possible; I can now only access a few. The integration of add-ons with Thunderbird isn’t working properly. After adding the German dictionary, Thunderbird froze; after adding ImportExport Tools, Thunderbird not only crashed but also wouldn’t start up again.

I start to make a new email message. I start typing in the recipient's email. Auto-complete finishes the address but misspells it. The recipient's email in all the address lists have it correctly. I recently saw the light and came over from Outlook. I imported my Outlook address list. It was correct in Outlook. Newest version of Thunderbird. thunderbird-MSIX - 1.0

Tags summary display has disappeared.

I can search for tags, but the convenient "tags folder" is gone. Please help.

Tried in safe mode with add-ons and toolbars/controls disabled. Error console is empty when assigning or removing tags.

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

I have everything I need from my old machine except my e-mail filters. If I copy the whole profile I will lose all of the sent messages and saved messages I have generated since I got Thunderbird up and running on my new machine.

I use the filters in Thunderbird a lot, so I am familiar with the setup. I need to automatically forward a message to my wife if it comes in from a specific email address. I cannot see a way to do this. Is it possible?

Version 140.10.2esr | Released May 8, 2026 I get this message every time: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Thank you, George Correia

Firstly, both laptops are working well. While one is still behaving quite normal, I am unable to install Mozilla Thunderbird on the other after having done a reset .. The "HUB" will NOT except my personal details i.e. email address & PW which I've used for years. I'll leave it at that for now ..

I am a long time Thunderbird user and set up a monthly donation. I no longer have access to that Email account and I need to stop the donation. The Donor portal won't work because it requires me to access my original email account.

Running Thunderbird 128.14.0esr (64-bit) via 64 bit Win11 Pro v. 25H2 on a Dell Inspiron 16 plus, Core i7-12700H @ 2.3 GHz, 24 MB cache, 40 Gb RAM, 877 Gb free on a 1.8 Tb Crucial T710 NVMe SSD drive. Integrated Intel Iris Xe graphics using 20 Gb shared RAM.

I have 5 email accounts (AOL = Yahoo, Yahoo, GMail, Verizon = Yahoo & MSN) each with a distinct IMAP server description. I also had my daughter's AOL account in the same TB profile.

On 5/9/2026, I foolishly entered my credentials in an AOL request for verification of her account (to allow TB access). As result, my jawarters@aol.com account and her jmwarters@aol.com account somehow became linked. Her email account in TB now contained only messages which were duplicated in my email account.

I deleted her existing jmwarters@aol.com mailbox and attempted to recreate it in Account Settings. Despite entering distinct IMAP settings (user name = jawarters@aol.com, imap.aol.com, port 993 and user name = jmwarters@aol.com, imap.aol.com, port 993) and having distinct SMTP settings with the user name in the Description, the recreated account again downloaded my emails into her TB account. The same happened when I opened TB on my desktop.

Interestingly, TB for Android v. 18 kept both accounts separate. I attach a copy of the TB Android k9s settings file which shows the same IMAP and SMTP settings as the laptop / desktop TB.

Help solve my self-imposed problem! Jim W

How could I have multiple email signatures for one account, like: - One very simple with name and email - One with company name, adresse, email, LinkedIn link.. - One blank

Email will not send. Message-- "Sending of the message failed. An error occurred while sending mail. The mail server responded: Email rejected. Please verify that your email address is correct in your account settings and try again." I am not sending to another person but testing with my personal email. Thank you.

I will preface this with no I do not have a backup - which is my fault. However I did not expect my account to be nuked into oblivion with no explanation.

As per the title, all my emails are gone. My local folders are devoid of anything I can use and am hoping that everything may be on a server somewhere. This is years of emails, important correspondence, bank information, business, etc. The ONLY thing I can think of is when I download the TB app for android and sync'd it using the QR on the desktop version of thunderbird. I then checked stuff the next day and everything was gone barring emails from that day, all folders, everything was gone. Is there no way to recover this?

• I am able to convert emails to tasks in Gmail
• I am able to flag emails in outlook to be read into Microsoft To Do
• I can tag emails in Thunderbird but then what?
• I have not seen an extension for this

I have MCI and i need to get tasks organized including todo items in email and calendar apps. Any help would be welcomed.

When I open Thunderbird email on my computer, it loads in my emails. These come from my Hostgator email server. The date and time of the emails show as the current date and time, not the actual date and time that the emails were received on the Hostgator server. For example, if an email was actually received on Hostgator 3 days ago at 5 pm. When I open Thunderbird at 9 am today, the date and time received will show today at 9 am. And nothing that I can see on the email that I have on my computer shows the actual receipt date. I have tried some things on my own, and I have chatted with AI and made some changes to what's showing on the headers. But nothing has worked to resolve the issue.

I use Thunderbird to store loacally some email from gmail and delete it from the online server.

Until october last year it was working flawless, to day I need to read an old email and I discovered that locally since october of some email is only stored the subject and somtime I only have the ticker that increase in the stored email email, but there is either not title or subject. I didn't change any setting in my computer or in the antivirus,, the only thing is that I perform the update of thunderbird as usual. Is it possible to recover these emails or they are gone forever?

Best regards
