I received a spam message this morning that had a "Disposition-Notification-To" (aka Read Receipt) line that had MY email address on it. I honestly don't know why a spammer would do this - but that's not the issue. I have Read Receipts disabled, but Thunderbird generated an email (to me) and sent it to my mail host. This seems like a bug. Even if the Read Receipt has my email address on it (making it mostly harmless), Thunderbird shouldn't have generated the message. Or am I missing something? Thanks.

I'm using Firefox for Android version 152.0.1 (Build #2016167575) on a Galaxy S24 Plus phone running Android 16.

Firefox is set as the default browser. It always opens whenever a task requires a browser. But when I try to open an HTML file by tapping or long pressing it, the dialog window that opens doesn't show Firefox as an option. Screenshot_#1_20260624.jpg

I have checked the settings in "Apps that can open links", all apps there show "In other app" In "Default apps", Firefox is under "Browser app". Screenshot_#2_20260624.jpg

What do I need to do so Firefox is either the default app for HTML files or at least shows up in the "Dialog window"? Screenshot_#1_20260624.jpg

Thank you!

The email address box does not accept the email address and comes up with an error message. The only way to send an email is to use a different browser ie Google. Emails are still received as normal on Firefox / BT mail

After Fire Fox does an upgrade for the next 3 to 4 days I cannot connect to web sites that circle just keeps spinning. Sometimes after about 20 to 30 minutes it might connect but then all I get is blank pages. Unfortunately I'm stuck with windows 10 for a while longer. Have tried most of the solutions refreshed 4 times and even reinstalled 3 times but doesn't change anything. Any ideas? Thanks

I update Thunderbird/linux to v.130 over a year ago, implementing oath2 with gmail. I do NOT want to do more updates because with each previous update I lose desired capabilities; I did this update only because of gmail's authorization requirements.

Worked fine for a while and then I started getting "authorization error" messages and could no longer access this account with Thunderbird. I have over 20gb of stored messages on my computer and do not want to do anything that will jeopardize this -- I generally delete all messages at the server. Google is of no help other than suggesting deleting and then somehow restarting the account. No. Someone suggested switching the account from oauth2 to password and then switching back again, but I am reluctant to do anything that might lose my messages. I can backup the entire profile, of course, but that just gets me back to where I was.

I went through the reauthorization process with gmail, including getting the 6-digit code, but the error still exists. I've been forwarding mail in this account to another account, but I'd rather go back to the REAL account. Help!

I have discovered Major problem with Firefox which affects the use of my btinternet.com email account . Since the recent update I am no longer able to add the contact name to a new email which I wish to compose automatically from my contacts (I am required to type it in full. I can still do it, with the shortcut of typing in the first 3 letters, when using other browsers such as Google or Edge or the Outlook muti mail account service but generally prefer Firefox. If this situation prevails I will ditch Firefox as speed of communication and addressing is of the essence to me. Are Firefox aware and are they correcting things?

Could any settings have been altered by the update - which contribute to my problem?

When I select one (or more) people from my email contacts in the dropdown list of BT Mail, the address(es) appear as "invalid" or "illegal" in the "To:" field. This has only happened since the last update to Firefox. This does not hapen with other browsers, so why should I be forced to change, just to send emails? It is a real PAIN. Having done a bit of research, it appears that there is Javascript issue. When can I expect a patch? I have enjoyed everything Firefox gives me, but this issue is giving me cause to consider moving

I keep getting prompt with this message stating the current config is set to block cookies (attached screenshot) and is occurring every interval. I had updated the app yesterday, some how after restarting the computer, it's popping up with the message.

Thunderbird 170.7 My son's email address has changed. When I write to him, the old email address appears by default. I cannot delete it from the address book, and I can't change it or edit the address book entry. If I am not careful, my message gets sent to the old address. Nothing seems to work in correcting the problem. Any help will be greatly appreciated. John

Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

Despite having receiving an invite (an email titled-Your Smart Window invitation is waiting) to try the Smart Window, on click, I land on a screen for joining the waitlist.

Wondering if I'm alone facing this or it is just another bug.

Best wishes,

When I open the sentmail folder, I want the receiptants name (email address) to show in the list of emails sent instead of my name (email address). How do I resolve this?

Hello,

I am experiencing a severe issue with the macOS system print dialog handling in Thunderbird, which started immediately after updating to version 152.

Environment

   * OS: macOS Tahoe 15.5.1 (26.5.1)
   * Hardware: Apple M4 (Silicon)
   * Thunderbird Version: 152 (Issue present) / 151 (Works perfectly)

Description of the problem: When I use the native macOS system print dialog within Thunderbird and select either "Open in Preview", Instead of opening the Preview app Thunderbird bypasses the command and immediately sends the document directly to the default physical printer. The same happens with "Save as PDF", the file-saving dialog is first presented, but after entering the filename the document is also sends to the default physical printer rather than being saved.

Steps to reproduce:

  * Open an email in Thunderbird v152.
  * Select Print...
  * in the Print Dialog window, select "Print using the system dialog" 
  * The system print dialog is opened
  * Click the PDF dropdown and select "Open in Preview" or "Save as PDF".

  Result: The document is instantly printed on the physical printer instead of performing the macOS system action.

Steps taken:

  * Tested with Thunderbird v151: The macOS system print dialog works perfectly as intended.
  * Upgraded to v152: The issue appears immediately and consistently.
  * All other applications (Safari, Chrome, Microsoft products, Apple Mail) work correctly 

This seems to be a serious regression in how Thunderbird v152 handles native macOS print system events and dialog actions on Apple Silicon / macOS Tahoe.

Any help or a fix for this would be greatly appreciated.

Best regards, Michel

I got notifications that I needed to update my email. I tried to follow the directions but after it was uninstalled, nothing else happened and now it's gone and I have nothing. I do not know what to do and am panicked because it's the only way I have to contact many people and it's really important to me.

Hi everyone,

My antivirus as quarantined 2 files from my TB profile:

• d:\internet profiles\thunderbird\profiles\z3rq1w7t.default\prefs.js
• d:\internet profiles\thunderbird\profiles\z3rq1w7t.default\virtualfolders.dat

I asked the antivirus to restore them, but the damage is done. TB has lost track of everything I’d stored over the years, including my email accounts, emails, preferences, etc. It’s like a fresh install.

But I can see that my profile still contains about 5 bg of data. So everything’s there, but it seems it no longer knows how to access it.

As you can see, my profile isn’t buried in the depths of Windows; it’s on my D drive. Perhaps I just need to ‘reconnect’ TB to the correct profile, but I don’t know how to do that anymore…

Any help would be greatly appreciated.

Thanks in advance. Guy

Guten Tag,

Ich hoffe Ihr könnt mir helfen.

Ich benutze Thundebird das erste mal und würde gerne wissen wo meine gelöschten Mails hin verschoben werden wenn wie auf dem angehängten Bild keine Einstellung vorgenommen wurde standardmäßig. Werden die Mails dann direkt gelöscht aus der kompletten Mail-Adresse oder bleiben diese irgendwo gespeichert?

Die Gelöschten Mails sind im Mail Konto nicht mehr auffindbar.

Viele Grüße
