This is answering Toad Hall and Mapenzi, who discussed my problem with the disappearance of the opportunity to put a copy of a message into a specific folder.

This facility was (and is) available on my MacBook, running TB 113. It has disappeared in this version (153). After a long time preoccupied with too many other things, I have now looked at my Add-ons lists in both versions. See attached screen shots. I think this explains my problem. But it doesn't *solve* it, as there is no suitable Add-on available. Perhaps, Mapenzi, you could ask your mate if he's willing to update the Add-on?

Mapenzi: it looked as though your screen shot of a blank message (in French) included an option for 'Copie à'. Is this standard in French HTML? (I can't persuade my TB to compose am HTML message to check, at the moment.)

Je vois que 'Mapenzi' est un mot Swahili pour 'amour'. Vrai?

Ok, so my Thunderbird updated this week to a new version, which I don't like very much but that's besides the point. Anyway, I always leave Thunderbird open (24/7) and I have a notification sound to let me know when mail comes in that I have been using for well over a decade now, but as of this last update my Thunderbird no longer plays that sound at all. I have tried every fix I could find online (ie: checking if its muted in volume mixer, making sure the default/proper sound source is selected, changing the drive for the custom notification sound, you name it I tried it) and NOTHING works. Even trying to use just the basic default notification sound doesn't work at all anymore. I have even gone to the length of completely reinstall Thunderbird itself but the problem persists.

When I click PLAY in the settings it plays the sound just fine, any sound I select, so I KNOW the sound is perfectly fine...it's Thunderbird itself that seems to be broken. It just will not play ANY notification sounds all of a sudden.

I need an email client open, and I absolutely NEED the notification sound. I have been using Thunderbird for like 15 yrs, I really really don't want to have to switch to a new client over something like this, but like I said I NEED that notification sound and if I can't get it working again I'll have no choice.

can anyone help PLEASE?!?! I'm desperate!

Hello,

I hope you are doing well.

I have another issue with Thunderbird. It labels many legitimate emails as spam, and they stay in my inbox.

How can I search for and find these messages in order to remove the spam label?

Thank you in advance!

Hello,

I hope you're doing well.

I noticed that in Thunderbird, my Yahoo account has both a Bulk and a Junk Spam folder. My Yahoo account online and in the app only shows one Spam folder for all such messages.

How can I ensure that I only have a single Spam folder, as is normal? I want to keep mail organization as simple as possible.

Thanks in advance!

Hi, I have Thunderbird installed and have been using it to do my email on a self hosted server and to connect to a google calendar account. This has been working for years, but now I'm finding when I accept a meeting invitation via email, its not being put through to the Google Calendar. I've reset the google calendar link a few time (deleted and created again from scratch). Its using the caldav interface to Google calendar. I'm also seeing this random message pop up (see uploaded image) - but there is no details on what to do. Anybody have any clues?

When I try to send a email from my secondary account I get the following error: A unique identity matching the from address was not found. Message will be sent using the current From field and settings Identity. In other words my main account sends a message to my secondary account. When I try to use secondary account I get the error message. The secondary account does not work now.

I have Thunderbird on laptop. I make changes to a contact in the address book and they seem to be made. When I close Thunderbird and restart it, all changes are lost and are back to what the contact information was before. This has to be fixed.

Evidently Thunderbird updated to 157.0.1 (64-bit) on October 1. If I select a reminder, from the list of reminders in the reminder screen, I will get the attached screenshot. I use to get a screen where I could delete the reminder. This screen has three dots. If I click on that there is an option to delete, but it does not work. The best I can do is delete it from the calendar.

I use to get the screenshot that shows selecting the event in the calendar.

Why does the "Delete" not work when I select the event from the reminder screen?

Was this a mistake, am I doing something wrong, or is this a new feature?

I cannot use the attach button to attach files to outgoing emails. Alt+Shift+A does not respond either. I am running Thunderbird from the "Thunderbird Setup 157.0.1" installer. I am able to drag and drop but that method is rather unwieldy. I recently upgraded Windows 11 to version 26H2.157.

Thunderbird is downloading new messages but failing to display them.

Other functionality remains active, ie I can see and open messages, delete all the contents of folders, compose and send messages, but when the software downloads new messages they simply do not display and cannot be accessed.

Not sure if it's relevant, but the message INBOX count appears to be stuck at the number 59, although more messages than that have been downloaded.

Bizarrely this is the message displayed whenever I now open the Thunderbird application (it was there when the problem first appeared and returns everytime). Out of desperation I even made a donation in the hope it would release the messages!

Thank you in advance, Steve Davidson

I used to be able to 'click' an email link,.. and the page would auto open in chrome,.. with a message at the top of the screen informing me this was happening. For some reason I must now use right button, and open in browser,.. in order to open the email link provided. s/w as follows:- Name Thunderbird Version 156.0 Build ID 20260915113124 Distribution ID ubuntu-snap-build User Agent Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:156.0) Gecko/20100101 Thunderbird/156.0 OS Linux 7.0.0-34-generic #34-Ubuntu SMP PREEMPT_DYNAMIC Wed Sep 2 14:29:37 UTC 2026 OS Theme Yaru-yellow / Adwaita Application Binary /snap/thunderbird/1259/usr/lib/thunderbird/thunderbird-bin

I have tried deleting the handler.json file but this does not fix or resolve the issue. My current Files & Attachments,.. has just a pdf entry,... set to preview in Thunderbird,.. and this duly open pdf's in a TB tab.

I have found the config editor settings,... for network.protocol-handler.external.http and network.protocol-handler.external.https and can verify they are set to true

But I still cannot just click on an email link,.. and have it open in my default browser.... Can anyone offer some options as to what i am doing looking where,.. wrong. Many Tx

For a few weeks now we have been unable to send emails through tbaytel server via Thunderbird. We get SMTP error. This happened after recent upgrades to Mozilla. Any idea when a fix will be out?

For a few days I'm having trouble with Asana mails (notification mails informing me about replies, comments, etc).

Clicking on the mail to view it freezes Thunderbird for a good 5 seconds while one CPU core spins at 100%. This only happens with Asana mails (or at least I haven't found any other problematic senders).

I guess it's a problem with validation or parsing of the mail's HTML content. But I don't know how to debug this.

I can't pinpoint exactly when it started happening, but it was around the time I've switched to the [new snap release track](https://support.mozilla.org/en-US/kb/channel-choices-thunderbird-snap-and-flatpak#w_snap-channel-changes-in-2026). But since this happens with Snap and Flatpak I think the culprit may be the 153.0 update.

Things I've tried:

• Clearing cache and msf files.
• Troubleshooting mode with add-ons disabled.
• Reinstallation. Creating new profile + importing old data.
• Switching from Snap to Flatpak
• Switching Message Body display to Plan Text or Simple HTML.
• Disabling HW acceleration.
• Checking console for suspicious output.

Anything I can do to create handle the problem or collect information for a proper bug report?

I have a filter setup to forward certain emails to another account. It has been working fine for years. Suddenly today I am getting an error message about not being able to contact the smtp server. If I manually forward the email to that same address it goes fine.
