Environment: Windows 10 22H2, Thunderbird 128.0.1esr 64-bit on two different PC's, "A" and "B".

Scenario and steps to reproduce:

(1) On "A", installed extension "remove duplicate messages" (version compatible with Tbird 128). Works fine. Profile on this PC is D:\Alice\Thunderbird\Main.

(2) Completely get out of Thunderbird on "A".

(3) On "B", launch Thunderbird accessing the same profile residing on "A" as mounted drive, "Q:\Alice\Thunderbird\Main". Mail, calendar, etc work fine. However, the extension is not available (No "Remove Duplicates" on context menu or Tools menu). On Tools :: Extensions and Themes, extension shows up with a blank (empty) icon.

(4) On "B", disable the extension, close the "Extensions and Themes" tab and completely get out of Thunderbird. Re-launch Thunderbird, go to Tools :: Extensions and Themes, and the icon has reappeared. After re-enabling the extension, it is active and works flawlessly.

(5) Then, completely get out of Thunderbird on "B".

(6) On "A", launch Thunderbird. It now exhibits the same behaviour for the extension: it is not available, and the icon is blank. Performing the same steps as in step (4) above restores the extension to its working state. And, you have probably guessed by now, it is no longer working on "B" !

Just to make sure this is not specific to this particular extension ("remove duplicate messages"), I installed another extension ("Quicktext"), and it behaves exactly the same (either singly, or with "remove duplicate messages" still installed).

So, it seems that you cannot use extensions from the same profile accessed via two different paths, one PC accessing it via a local drive and another accessing it via a mounted drive. I want to re-interate, before someone asks, that Thunderbird is completely down on one PC before I try to access the profile on the other PC.

Has anyone seen this behaviour on Tbird 128 ?

Thanks.

Since that last update (128.0) I can hardly tell the difference between read and unread messages. Particularly when there are just a few messages of the same kind with no basis for comparison. I've looked through previous threads and found some solutions that involve modifying scripts. I had ChatGpt help me with the maneuver , but it didn't change anything. I would also be satisfied with another font in the headline or another background color - just something that ensure sure I do not miss an important mail in the stack.

I want to export from Thunderbird messages to Yahoo, or import from Thunderbird messages into Yahoo. Thunderbird is on Win 10 Chrome desktop and Yahoo is on 10 Gen iPad latest ios. Both are on the same home network.

I also would like to know how to delete the Thunderbird Account and reinstall it and keep the messages currently on it.

Thank You

Hi, I'm running into the issue where I have a public certificate issued to security@companyname.tld as they don't issue a separate one for most employees, but Thunderbird won't let me use it for sending (I think it's used when replying?) it to firstnamelastname@companyname.tld

Is there a way around this?

Hi,

I have been using Thunderbird happily for a long time, most recently version 115.13.0 on my Ubuntu 22.04 partition. Recently I installed Ubuntu 24.04 on another partition, including Thunderbird 128.0esr, now installed as a snap package (it's a recent change in Ubuntu; instead of apt package previously).

The new Thunderbird correctly reads my emails (imap) but it cannot send emails, save drafts or mark emails as read on the server. So I have Thunderbird 115 on the old partition working perfectly, but Thunderbird 128 not working on the same GMail account (I also have the same problem with another non-GMail account). I checked the smtp settings carefully, they are identical between the two versions.

It's possible I made a mistake, but I'm at a loss about what is wrong. How can I diagnose and solve this problem?

(I know that I could reinstall Thunderbird with the apt package, but I assume that the snap package should work too and I would like to understand the cause)

I'd be grateful for any advice

after i have suddenly upgrade to newest version my autocount can't send the mail by mapi system integration in software. i use that program is inside autocount called 'send by email (Ms Outlook compatible)'.

it appear error msg failed to send msg.

how i can solve it.i have try downgraded to old version and set default apps in default apps windows also can't.

thunderbird 115.13.0 how do i see my all folders with ALL of the emails? When i go to unified folders sent/inbox it flips the most recent email to the bottom, how do i flip it back, are there any videos, anywhere, that i could watch and learn from????? i can save us both a lot of tme if i could watch a video on how to do this? thank you...b³

for example: also how do i make a directed screen shot of a page? as opposed to the whole page?

Once again, since my husband suddenly passed 13 December 2024, I cannot send or receive email via my intoknow.com account.

Previously, it was somehow "repaired." Please, i need this account to stay active.

Having downloaded TB version 128, the details for TbSync via add-on manager states that it is not compatible with this version. My questions, as a first timer with TB are:

1. Can I still go ahead and use TbSync with version 128? I need it to get contacts and calendar from Outlook.com

2. Will the planned native support in 128 for Exchange ActiveSync allow for easy switch from TbSync?

3. I thought I would download TB 115 which TbSync works with, but all download buttons seem to point to 128 and I can't for the life of me find the actual download link for TB 115.

Thank you. Sep

After an update a few months ago, all installations of thunderbird always open the calendar tab when the program starts. Previously, calendar tab only opened if I opened it (or maybe if it was left open when last shut down, idr now, sorry). This is only a nuisance, having to close the tab each time I start tbird.

I didn't post about this immediately, as I figured others would experience the same issue (or related) and devs would fix the problem. But it has been several months now and this does get to be annoying. I know that merely clicking a close button shouldn't be that big a deal, but I don't understand why this would become the default; moreover, why there doesn't seem to be any way to disable the calendar or at least modify this new behavior.

I've been using tbird for at least a decade and found it to be reasonably simple to use. I use the calendar function, but only for some installations. I would appreciate being able to change the behavior of the startup or maybe just disable calendar altogether where it isn't needed.

Thanks.

I've been using Thunderbird for my email for many years with no problems at all that I can remember, but all of a sudden, just in the last couple days it has become very, very sluggish to respond to clicks and commands. So far as I can know, I've not done anything that should have caused this to happen. Any ideas and/or suggestions?

From my inbox I normally highlight any emails I want to send to trash and press the DEL key. This morning when I tried to move these across I got a message advising that if I continue it would remove all files from my trash folder. My server settings are move them to nominated folder - see attached. How can I delete from the inbox and transfer to the trash?

The second problem I encounter is whenever I attempt to log into my Thunderbird account I am directed to go through the "Create an account" process as if I don't have an existing account???

'Have enabled and disabled. restarted, both times. Tried troubleshooting mode, and cleared the cache. Could not find the setting in the config screen. Not sure I was looking for the right thing, anyway. Your help will be greatly appreciated. John Looze

I am currently on Ver 115.12.2 (32-bit), but I've had this problem over several versions. I recently downgraded from the 64bit version (for a different reason), it had the same issue.

Old messages in the Inbox are listed twice, including those that have been read. New incoming messages are not duplicated, messages where I've deleted the duplicates are not again duped. Messages that get filtered to or moved to folders are not duped. Old messages that are in folders are not duped.

I have several email accounts in TB, and I only see this on my most active- of course! I have compacted all folders many times and rebuilt the Global Database with no effect. I tried opening in Troubleshooting mode and they are still duplicated. It is a POP account.

Last night all my messages current not received and saved and received disappeared. at one time my pharmacy came up but when I got out and went back in they disappeared, I did try to empty basket on junk mail but couldn.t
