Forum zgromaźeństwa Thunderbird

Starting in mid November 2025, my subfolder - named Apps, disappeared from my folder structure. I've used this for many years without an incident. It remains on my structure when I open my email via a web browser, but is absent from Thunderbird.

What changed? Is there something now forbidden about the name?

As I have message filters created to sort all my emails, it is a real problem now with Thunderbird. I would be grateful if someone can enlighten me on how to solve this issue. Jerry

Have TB on my laptop (146.0.1 (64-bit) on Win11) all set up the way I want it. Would like to "clone" those settings/profiles to my desktop. AI site said, "Copy profiles folder and profiles.ini to the new machine." Didn't work. Asking me to set up from scratch. Laptop is on "standard" edition, think desktop is on beta. Is that the problem? What do I need to do?

I'm using Thunderbird 140.6.0esr under 64-bit LMDE (Linux Mint Debian Edition) v6.0, fully up to date with patches.

Last night, Thunderbird was working justfine when I switched the PC off. This morning, when I try to collect mail, I get a dialog box with the message

Unable to write the e-mail to the mailbox. Make sure the file system allows you write privileges and you have enough disk space to copy the mailbox.

I have multiple Terabytes free on the drive, and I have gone through a full file listing and checked all the file attributes. Yes, I have write access.

Just to be sure, I ran a chown against the entire ~/thunderbird directory (~/.thunderbird is a logical link) so I own ~/thunderbird and everything beneath.

I also ran a fsck on the drive, and fsck gave it a clean bill of health - no errors reported. This was just a normal fsck, not including a badblocks check, although I did run badblocks against the drive when I got it new, about two months ago.

I am out of ideas. I suppose I could try running TB with a sudo, but I'm not really happy with doing that routinely.

Does anybody have any ideas? . Thanks,

Brian.

for some reason a few random emails will come to my iphone, but not Thunderbird on my Windows 10 PC. Not in spam, not anywhere but on my phone. Anyone else having this issue?

I've always experience occasional TB crashes. According to my log history there was 1 in July, 3 in Aug, 2 in Sep, 2 in Oct, and 6 in Nov. I never really paid attention since the reboot was quick. But now in December I am losing work and it is a major problem. I've had 30 crashes in Dec and 21 in the past week. I have only 3 add ons and they have not changed, and a Copernic connector. I disable the Copernic connector and it didn't help. I have the same 140.6 on my Surface Go with the same add ons, except for Copernic and it runs fine. On both PCs I use Malewarebytes and WinDef. I have put exclusions for them in their setups. Even with MBAM completely disabled I've still had crashes.

I cleared the Cache and no help. I've even had occasional crashes in Troubleshooting mode. Here are my last 5 crash IDs

bp-070bf941-4e8b-41a3-8b84-3e3440251224 bp-a936f7c2-9ee3-4c38-b304-dab830251224 bp-8be9cf9e-8f2f-49bb-95cf-47e780251224 bp-12f8fc2c-c505-40f0-8c67-44b730251224 bp-9013fb78-086c-4327-9de8-62db30251223

Interestingly I’m also experiencing crashes with Firefox, especially ChatGPT. I cleared the ChatGPT history and that helped but did not solve the problem. I cleared the Firefox cache and in troubleshoot mode still have issues.

Otherwise my win11 PC seems to be working fine. I’ve run chkdsk and all is ok. Also scannow is ok.

Is my next step a profile rebuild?

I use a private email server (mail.ragan.us. I have set up Thunderbird on Linux Mint 22 with the same email server settings I use on Outlook in Win 10 and Apple Mail on IOS 26 which both work fine. I created the account in Thunderbird and it showed success. When I try to get mail for gary@ragan.us,Thunderbird shows connected to mail.ragan.us, but will not download mail from that server. Any suggestions? Thanks.

Steps to reproduce the problems:

Perform a Global Search (ctrl + K). Search for any string. Just make sure there is at least one search result. > Click "Show results as list". > Right-click on the search result in the Message List Pane. (Please see the footnote.) > The pop-up context menu has two problems:

(1) There are redundant dividers. (Please see the first attached image.)

(2) Hover the mouse over "Tag". The pop-up submenu of "Tag" is incomplete. The menu includes "New Tag" and "Manage Tags". However, "Remove All Tags", "Important", "Work", "Personal", "To Do" and "Later" are missing. (Please see the second attached image.)

---

These problems (redundant dividers and incomplete submenu) also occur in Troubleshoot Mode.

---

These problems only occur after using Global Search and clicking "Show results as list".

If I right-click a message in the Message List Pane of a regular folder (such as the "Inbox" folder or "Templates" folder), the pop-up context menu displays correctly: There are no redundant dividers, and the submenu of "Tag" is complete. (Please see the third attached image.)

Operating system: Windows 10.

Versions of Thunderbird: 140.3.1esr (32-bit) and 140.6.0esr (32-bit). Previously I was using 140.3.1esr (32-bit), and currently I am using 140.6.0esr (32-bit). Both versions have the same problems.

Footnote: When I right-click on the search result in the Message List Pane, the following error messages display in the Error Console (please see the fourth attached image):

Uncaught NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgDBView.getThreadContainingIndex]        mailCommon.js:647

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.

my thunderbird freezes at the point of checking mails. when i try to update it, it opens a new application completely and doesn't update my present one. i also can't find the location of the app or the data. pls help!!!

Thunderbird 140.6.0esr (64-bit) does not highlight the open message in the list. There is no indication of which message in the list I'm currently viewing, the it used to be. I like to have that instant recognition.

Bonjour,

J'envoie, depuis une mailing liste d'OVH, un mail présentant l'aspect suivant : une image encadrée (cf: PJ) Lorsque je le réceptionne avec Thunderbird, seule l'image apparait (cf: PJ)

Le code source de cette dernière montre que le code html du cadrage est présent. Un réglage bloque la lecture de l'html ?

Que se passe-t-il ? Merci de votre aide.

1. I am getting Mozilla Thunderbird ESR notices pop up when I log on to my PC (W11). I checked my Thunderbird version and I have 146.0.1 and I am on the release channel so why am I getting these notices ? 2. Recently I noticed that when I try to move e-mail messages to a specific folder, I right click on the message and get the prompt Move To and then Recent Destinations where the problem exists. The list of Recent Destinations used to be in alphabetical order and now it is sorted by most recent destination time. This slows me down considerably. Please revert. Thanks !!

1 How can the list "recent folders" in the icon "store in" be sorted alphabetically? (sorry, my version of Thunderbird speaks German) It used to be alphabetically, but now is sorted chronologically.

2 I cordially suggest to add a function exactly like this one, but with item at my own disposal (maybe the favorite folders).

Thanks, Martin

I am using an email server that currently is using certificates that have expired. That problem is being worked on. In the meantime, whenever I access the server to open a folder, I get a pop-up notification telling me that the certificate has expired. I go ahead and confirm the security exception and check the box to permanently store the exception. Trouble is this ISN'T being persisted, when I open a different folder I have to go through this process again in order to access my emails in that folder.

Me thinks you got a bug in your software Kemosabe!
