Thunderbird Community Forum

I use a number of add-ons to help me out. Unfortunately, the following add-ons aren't working right now: Quicktext, Send Later, TbSync (where and how do I integrate it into Thunderbird?). When sending an email, I have to go through “File” > “Send”—there’s no button for it. The VBA call to send a generated email truncates the string, so the attachment isn’t included.

I’m sure some add-ons will be updated. But this is hitting me hard right now.

My recollection is that prior to a recent automatic update to Thunderbird 140.12.1esr (64-bit) when I had a message composition window open, there were "SEND" button and possibly a "SEND LATER" button (to the left of the addressee and cc addresses in addition to the keyboard shortcuts (CTRL ENTER and CTRL SHIFT ENTER).

Following the update, there is no longer anything to the left of the addressee information. I have checked the toolbar menus, and there do not appear to be any button options. I can still send messages, but the lack of the buttons is a hindrance.

After updating to 153.0.1esr(aarch64). the SEND button has disappeared. There's no way to send an email. (I can receive emails.) I am a Mac mini M2 Pro. OS 26.4.1

I cannot find a link to download a previous release of Thuderbird, which was working fine until this update.

My brokerage firm states that it cannot notify me via email for conformation transaction. How do I add this firm's domain to my address book so that its emails will be received my me?

I am encountering a message of "The installation seems to be incomplete. Please check your hardware and disk setup and/or re-install." when trying to run Thunderbird.

This first occurred on a system that had been working for a while. An update may have been installed.

Here's what I've tried. -

Uninstall Thunderbird (along with Firefox and Mozilla Maintenance.) Checked for Program Files/Mozilla folder (all were removed). Run SFC / Scannow Run CHKDSK Installed pending Windows update. Restarted the System Renamed (essentially removed) Profiles folder Turned antivirus software off Downloaded and installed the latest version of Firefox, then Thunderbird. Launched Thunderbird. Still received the same error..

Any ideas on how to resolve the issue?

My Mac last night lost thunderbird (and numerous others things) and it's setting itself up again. I get an error that smpt already exists and I can't go any further! What's going on? Using Comcast Mail.

I have followed the instructions that several people give to transfer my existing Thunderbird installation to a new computer where I have just installed Thunderbird. That is I copied the Thunderbird folder and put it in the Roaming folded found in %appdata%. Both computers are on Windows 11. When I open the new Thunderbird, it does not recognise it. Furthermore, in Help>Troubleshooting information>Profile folder when I click to open the folder, it looks for a folder that is not in my previous Thunderbird installation: qr19mupe.default-release instead of the one that came with my imported Thunderbird folder. Has this happened to anybody and found the solution? Can anybody help please?

Bonjour, Je vous promets que je vous fais un don dès que vous aurez mis fin à votre publicité mensongère à propos des Dossier récents : ils ne sont jamais triés par ordre alphabétique, quelque soit le paramétrage demandé.

I have a new PC. I have added five email accounts, three different hosts, with some difficulty. Thunderbird finds the details for others but then refuses with the message Authentication error. Unable to log in at server. Probably wrong configuration, username or password.

I added Thunderbird by copying from my old PC. The hosts for those not yet added are the same as those added.

When I am on my thunderbird email page and switch to page where I used to find my address book. Now all I see is an option to create a new address book. What happened to my old address book? screen shot.HEIC. screen shot.HEIC.pdf

How do I fix this Sending of message failed. An error occurred while sending mail. Th mail server responded Policy -MFRM53 Relay Denied-unauthoruzed. Please verify that your email address is correct in your account settings and try again What should I do

Your last update included a Yahoo signup splash screen. Please remove it in the next update. It is annoying and does not serve any purpose other than ccnect me to Yahoo web mail. If I wanted to use that service, I sign in for it. I am content with using Thunderbird. Or at least give me the option of removing it myself. Thanks.

I have an email account on Thunderbird that I no longer use that I want to delete that account. I can very easily add an account to Thunderbird, but I can't seem to find any way to delete one. Is it even possible to delete an account?

I have been using Thunerbird for many years. Lin fixed a problem with an f8 toggle issue last week but I had 2 downloads for thunderbird in my desktop I tried to open 1 of them and it said there was a file it could not open. I opened the other one and it asks for my password. I keep 2 notebooks with my passwords but I can't find one for thunderbird. I tried to do a restore in windows 11 but the restore point from weeks ago said it could not complete because of an open vpn or some other file. There are no earlier restore points because I had a new ssd and some memory upgrades. Is there a way to recover that password? Probably no problem if I opened it from the tray but I was working on a printer problem at the time and had the desktop open. Thank you

Since some time my standard number of print copies in Thunderbird has changed from 1 into 2. I have to adapt this number each time I print. How can I change this back?

I spend the last hour or so in sheer panic and doubting my sanitiy as an email I was just reading disappeared from every mailbox I have here (I have 8 mailboxes in Thunderbird) . Also for whatever reason search is missing from the title bar.

The email was "archived" by Thunderbird inthe "Local Folders" I never use local folders as local folders is silly in 2026 imo. I have my own mailserver which is perfectly save and backuped and stuf I don't need yet another location were mail can hide.

Anyway that was a bit of a rant. This would not have happend if this sille ¨Local Folders" didn´t exist at all. But I seem unable to get rid of it.

How do I remove ¨Local Folders" from Thunderbird?

hello everybody thank you for your help i have a connection problem between thunderbird (ubuntu 26.04) and my email provider mail.fr. When i open thunderbird the following message appears "unable to connect to imap mail.fr".

But I have a second computer also under linux 26.04 which has no problem. The installation is the same, automatic.

So I don't understand why this connection is not made. I checked the passwords, the connection timeout, I redid the thunderbird installation, I recreated the email account mail.fr...

I don't understand. If anyone has an idea, a tip, I'm all for it. The problem does not come from mail.fr, because I access my emails on their site without any problem.

thank you in advance for your help jmb
