Thunderbird version 147.0.1 does not send email. I use Windows 11 Pro with all updates current. I can receive but cannot send (reply to) emails. I have not changed any email settings. What is the solution?

Thunderbird 140.7.0esr allows me to e-mail my OpenPGP public key to myself, but it doesn't seem to have any way for me to get access to my private key. I was wondering how to export keys? Thanks!

A website I have accessed many times before now redirects me to an italian site. Is this because of the beta translation? I'd like to be able to go to the real site. mecaforpeace.org

We are a fatcow.com user, I know the company has been bought out by another company, but outlook stopped working. They no longer support outlook 2010, so I switched to Thunderbird. I get all my new messages fine, but it errors trying to send new messages. Error message has been uploaded.

thx

I have smtp.gmail.com set up as my outgoing server (port 465, username = my gmail address, Authentication = OAuth2, connection security = SSL/TLS, also tried STARTTLS with port 587). There doesn't appear to be any way to set the password in the "Outgoing Server (SMTP) Settings", even when I click "Edit". Nor can I add a password to the "Edit/Privacy&Security/Saved Passwords" dialog box (which allows you to see existing passwords or remove them, but not add any).

When I try to send an email, the "Sending Message" dialog box pops up, and after a few seconds a second box pops labeled "Login to account 'smtp.gmai.com' failed". This box has three buttons: "Enter New Password", Cancel and Retry. Clicking on the "Enter New Password" button does not offer me the chance to enter a new password--instead, it immediately takes me back to the "Sending Message" box, which then immediately takes me back to the "Login...failed" box. There is never an opportunity to enter the password!

TBird 140.7.0esr, Thunderbird for Linux Mint. Mint version 22.3.

Sending works ok if I choose a different SMTP server.

Hi All, I have been sending emails through Android Thunderbird, but they aren't being synced to the server, so I can't see them anywhere else. I've set the Sent folder to sync (as well as the Inbox). Pressing the sync button just spins the indicator, but doesn't actually sync. When I try to move or copy messages, an error comes up saying that messages can't be copied or moved that aren't synconised. How can all my messages (sent, inbox, everything) be synced so that I can see them everywhere? I've just turned on sync debugging, will see the results soon.

I am trying to find a way to restore the previous tabs that I had open. All the standard restore procedures out of the History button or elsewhere are not working due to the account change. Here's the background and scenario: Original account created 1 month ago on old Linux PC New PC purchased and Ubuntu Linux 24.04 installed Firefox installed and configured, bookmarks imported from .html file. No sync account was ever signed in to. Open a crapload of tabs that I wanted/needed to interact with (yes, I need a better task management system) Finally decide to log into sync account, successful sign-in Close browser for PC restart. Upon restart, all configurations from 1 month ago on old Linux PC are present, and no previously-opened tabs come back. Restore session/restore tabs/restore browser all are greyed out, no data to access in history anywhere. Signed out of account, closed browser window and restarted. Still displaying config from old sync account even when not logged in (different theme, toolbar settings)

I am unable to locate any files in the pathway Home/snap/firefox/common/.mozilla/firefox that clearly indicate multiple profiles; there is only one distinct profile folder present. I haven't cleared cache or anything, trying to not touch it more. Is it possible to restore or even see the URLs of those tabs from my session prior to logging in to my sync profile?

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

Lately my Firefox app window will just randomly close while I'm using it. I notice most often on Facebook, but that's because it's the most often used page.

When I reopen the app, it's like I just opened it, not like it got minimized.

What's wrong with it? I have it updated to current version, as well as I've run malware and virus scans to see if it's my phone. Nothing found.

Hi, my Gmail account on Tbird is failing to copy sent emails to the sent box. The email hangs with "connecting to Imap Gmail" and then "your email was sent but a copy could not be placed in your sent box". I have re-downloaded Tbird, deleted and re-connected to Gmail but the problem persists. I have tried the fixes mentioned on this forum in 2024 (e.g. changing the destination folder as suggested, changing threads to "all") but nothing seems to work. Help!!

Untill last night i could conect with that site https://imtw.ru and its sub forums without eny problem . Today when i press the link i recieve a message that the connection is rejected "Failure to secure connection". As you van see it has the https:// infront and i repeat i was able to connect last night. What may be wrong?

TBird Version: 140.7.1esr

Since yesterday I can no longer click through with hyperlinks inside an email message.

I don't understand this.

I have already tried all the troubleshooting items to no avail.

To my mind, a change was made to TBird's functionality and this is stopping the click-through to the default browser and the opening of the page linked.

Ich bin langjähriger Firefox-Nutzer und habe bereits mehrere Troubleshooting-Schritte durchgeführt. Trotzdem benötige ich konkrete Unterstützung für dieses spezifische Problem.

PROBLEM KURZ: Ich habe ~1.625 Lesezeichen auf meinem Android-Tablet (Gerät D). Diese Lesezeichen syncen NICHT zu meinen anderen Geräten (Windows 11 + 2x Android). Alle anderen Geräte bleiben leer – keine Lesezeichen vorhanden.

GERÄTE-SETUP: - Gerät A: Huawei Notebook, Windows 11, Firefox (neues Profil „CleanSync") - Gerät B: Android-Handy, Firefox - Gerät C: Android-Handy, Firefox - Gerät D: Samsung Tablet SM-X200, Android 14, Firefox (QUELLE der Lesezeichen!)

SYNC-KONTO: - E-Mail: deviation@nickname.berlin.de (Neu erstellt, alte Kontos gelöscht) - Alle 4 Geräte angemeldet + Sync aktiviert - Sync-Einstellungen: „Lesezeichen" ist überall CHECKED ✓

WAS ICH SCHON VERSUCHT HABE: 1. Firefox-Cache auf allen Geräten gelöscht (A/B/C/D) 2. Firefox-Daten auf Android B/C geleert 3. Alte Sync-Kontos server-seitig gelöscht (via accounts.firefox.com) 4. Neues Konto erstellt + sukzessiv alle Geräte angemeldet 5. WARTEN: 2+ Stunden gewartet → Keine Änderung

SYMPTOM: - Gerät D: 1.625 Lesezeichen LOKAL sichtbar ✓ - Gerät A/B/C: 0 Lesezeichen (komplett leer) ✗ - Sync-Status A/B/C: Zeigt „Sync enabled" + letzte Sync vor X Min - → Aber Lesezeichen kommen NICHT an

VERMUTUNG: Lesezeichen von Gerät D laden NICHT auf Mozilla-Server → andere Geräte können nicht syncen

LOGS VERFÜGBAR: - Gerät A: `about:sync-log` (kann Screenshots bereitstellen) - Alle Geräte: Sync-Einstellungen-Screenshots

ZWEI FRAGEN: 1. Diagnose: Was kann ich konkret testen, um zu debuggen, warum Lesezeichen von Android D nicht syncen? (Bitte KEINE Verweise auf FAQ – ich benötige individuelle Anweisungen für dieses spezifische Problem.)

2. Fallback-Option: Gibt es eine Möglichkeit, die 1.625 Lesezeichen von Android D OHNE Sync zu sichern/exportieren (z. B. Datei, SQL-Export, Cloud-Backup)? Ich könnte sie dann manuell auf die anderen Geräte importieren.

Danke im Voraus! 🙏

I am do not get sound using audio recorded with akamai player with Fire Fox browser. I tried the same link using Edge browser and the audio works.

I have tried clearing the cache, but still no sound.

How do I resolve this issue using Fire Fox as my default browser? Is there an audio extension that is needed?

When I try to upload a file from my mobile device, the file doesn't appear. Uploads from Google Drive are displayed, but I can't select the file. I was able to upload images to this page. What could be the reason?

The Thunderbird password I've used for YEARS (and is stored in "Saved Passwords") no longer works. I have two laptops with the same password, and they both ceased (on the same day) allowing downloads (or sending) of emails. This occurs on both my laptops -- one has TB version 115.10.1 w/ Windows 10, and the other has 140.5.0esr w/ Windows 11. It also occurs on my iPhone when trying to access the mail server.

Could the problem be the mail server itself?
