Thunderbird Community Forum

Hello,

I am using Thunderbird on my arm64 Linux machines (Raspberry Pi 4 and 5 and my Odroid C2) and I want Thunderbird to send the correct platform information in the User-Agent line. After enabling Thunderbird to sent the full User-Agent line the following information is currently sent:

User agent:Mozilla/5.0 (X11; Linux x86_64; rv:140.0) Gecko/20100101 Firefox/140.0 Thunderbird/140.9.0

Everything is correct except for 'x86_64'. I would like to have sent the actual 'arm64' information because I'm proud using my small ARM64 machines as workstations and as a replacement for classic PCs and I do want to have this information distributed with every mail I am sending with Thunderbird.

Is there an easy way to get the correct information about my arm64 machines into the User agent line?

I am happy for any advice and help.

Kind regards,

     Roland

Settings have been set to move Spam to my spam folder. Although Spam is identified it does not get moved to my Spam folder. It used to happen but an upgrade a while back seemed to stop it happening. I have tried undoing and re-doing settings to no avail. Can someone help please?

Thunderbird Filelink uses end-to-end encryption and files are only encrypted/decrypted locally but unless the code running on your system is reviewed and validated you don't really know what it does. I would think that every time recipients click on the link and use the web interface to download a file, their browser is sent a script that does the decoding. Similarly, if you use the web interface of a Send instance to send a file, your browser is sent a script for encoding.

If the above is correct, how do we know these scripts are always the open source scripts that have been independently validated? Isn't it conceivable that a Send instance may send you a customized script for encryption/decryption that compromises encryption? This could be done with selected targets to avoid attracting attention too.

Using an iMac running vs. 140.9.0esr(aarch64) "up to date", emails addressed to "***@shaw.ca" I receive error reports that says "Server shaw.ca returned" "message reached max retries". Example: Email was sent at 04/01 13:31 and the error msg was dated 04/02 02:16:11. This is not a one-off trial; similar errors are obtained with different "@shaw.ca" addresses.

Using Thunderbird vs. 149.0.1 (aarch64) on a Mac Pro, running on the same local network and same telco connection as the iMac, messages to "***@shaw.ca" are processed in normal time without error msg.

The other day previews of messages quit working in Local Folders>Inbox. New messages will show the preview, but not any of the older messages. The preview area is just blank. I drew an arrow to the preview area.

Hello,

Windows 11 - Thunderbird 148.0

In received message bodies previous replies are blank. If I select and drag an area in the desired reply the content of the reply magically appears. I've attached two images of this behavior. What setting may be causing this?

On 4-2-26, TB stopped downloading messages from / and uploading messages to, gmail.com

I've checked my Server Settings, and they all LOOK correct: Password, OAUTH2 Password), Connection Security (SSL/TSL)

I CAN access my gmail account via my Web Browser; my messages ARE THERE

I am trying to export multiple messages that were sent to me encrypted with my pgp key as .eml files that contain the unencrypted message without needing to be decrypted. When using the default save function and ImportExportToolsNG on both server messages and locally stored messages, the .eml files exported just contain the encrypted pgp message block. Is this possible or will I have to manually decrypt each message?

Hi there! I cannot get Thunderbird to work with the SMTP-server of my new Outlook account. I checked and double-checked the server specifications, the password, tried OAuth2 as well as login with password. I checked that SMTP is activated in my Outlook settings. Checked Thunderbird and my MacOS for updates as well, of course. I even created a new profile in Thunderbird. The result is still always: "authentification failed". Can someone help? Thanx...

Hello, It's getting very frustrating some time hotmail folder/emails are there ans other times not, then some times it will start a downloading all messages folders as if it a new set-up. I have follower all info I can find but it just stays the same.

Kind regards Chris

Suddenly Thunderbird is trying to access a non existing icloud email account. I have never used icloud and no such account is listed in Thunderbird. Yet it keeps asking for the required password. Again, no such account, or password have ever been given to Thunderbird. Trying to disable icloud goes nowhere as it doesn't recognize any passwords. 115.18

Hallo, die Kontakte im Adressbuch werden mit Carddav zu meinem Mailaccount (IONOS) nur teilweise syncronisiert. Die Syncronisation endet bei 1000 Einträgen, ist das so gewollt oder kann ich dies ändern? Fehlermeldungen gibt es dazu keine. Die betrifft die Thunderbird un Linux Ubuntu. Ich Thunderbird Windows 11 funktioniert alles.

Liebe Grüße Peter

Hi,

Can you please have a look at the following problem: I decided to re-index my mails. after I realized that the search results did structurally not contain any messages from 2026. I deleted the global-messages-db.sqlite. However, this did not lead to the desired result. After processing some folders, I can see in Activity Manager that the indexing stands still after having processed about 20% of the "Sent Mail" folder of a gmail account. I waited more than 12 hours, but the number of indexed messages did not increase. The file size of the global-messages-db.sqlite at this moment is only 2.3 KB, while the original database was more that 300 MB large.

I already tried the following without success:

1. restarted TB
2. deleted the database for the second time
3. restarted my PC
4. repaired said "Sent Mail" folder

I am running Thunderbird 140.9.0esr on Windows 11.

Many thanks in advance for your replies.

Thomas

accounts@firefox.com　から以下のメールが届きました。 認証しないといけないと思いますが、やり方を教えてください

A couple of weeks ago you created a Mozilla account, but never confirmed it. For your security, we will delete the account if not verified in the next 24 hours.

I have followed all the other recommendations with, no luck. I am on Windows 11 and use Eset virus software. Thunderbird is not listed as running it Task Manager, and there is no Profile.lock (think that was what it was called) in the profile directory, and I have deleted the existing profiles and recreated it. I have uninstalled and reinstall Thunderbird, and I have rebooted my computer. I am frustrated and concerned I will loose saved emails and my address book! Help.

Hi, I am hoping that the community can help me find an answer to this. I have two computers that I use for work. The one in the office has TB running all the time and before I leave for the weekend/vacation I would close TB, copy the profile folder to a USB (or copy it to cloud) and then paste the profile folder on my work laptop (at home). While all the settings get copied (local folders structure, addons etc.) as I use IMAP, it downloads all the mail on the new system regardless. I thought that it should have the latest mail downloaded as part of the profile folder, is that not the case? The bigger issue is that none of the Completed Tasks Lists, Templates, etc. get updated. It still shows all the older stuff on the work laptop and no updates carry over from the PC (at work). Going through the profile folder I see multiple copies of the files prefs.js, folderCache.json, global-messages-db.sqlite appended as: prefs-computername.js and folderCache-computername.json etc. (The computername is the name of the PC - office/laptop) The profile name is the same between the two computers. TB is only started after the profile is copied locally. TB version is the same between systems. I am left scratching my head why somethings are copied but not others. Hoping that the community can help me here. Thanks!

So I have a couple of accounts that do this and not on others (Same domain and server) When the messages come through they are doubled like they are on a thread, but the same exact message. All settings in Thunderbird and the server email config are the same for all addresses,. I have three out of ten that do this for some odd reason.
