Suddenly since Friday 21.08.2026 morning every single person in our company started to call the IT department that their Thunderbird client is printing out blank pages (white pages) instead of attachments from emails.

What is happening -> Employee gets email with PDF attachment -> clicks to open it in thunderbird print preview -> prints -> blank page comes out.

What works -> Downloading the PDF and printing it. Opening the PDF in any other browser than Thunderbird and printing it.

No settings or updates were changed and it's a big issue affecting multiple computers.

What I tried doing -> Trying different printer (No fix), Resetting print settings in thunderbird (No fix). Trying other PDF attachments from older emails (No fix). Looking at print settings in windows (Which I didn't change since it only doesnt work in Thunderbird).

Problem is that on thunderbird in my office, This doesn't happen. We have the same versions and settings.

I tried opening the error console while opening the PDF and on computers where it doesnt work it shows me an error with along the lines of "This document is open in compability mode due to **** header <doctype html>" Something like that but i would have to check again.

I don't get this error on my personal PC.

When I try to print a PDF attachment it comes out as a blank sheet. This used to work OK. The print preview is fine. I have altered the settings to open PDFs in acrobat as a workaround. Any help appreciated.

Something seems to have changed recently with the PDF rendering in Thunderbird. I received an email with a PDF file attached. When I view it on the screen it looks fine, but when printing it out from within Thunderbird part of the top of the first page missing; it looks like part of the image is behind a white rectangle.

When I save the file and print it using Acrobat Reader it renders fine.

I don't know what to make of this behavior, but it does seem to be new and there is a difference between how the file is printed from Thunderbird as opposed to printing using Adobe Reader.

Thunderbird 152.0.1 on Windows 11 PC.

I have been using Thunderbird for years with no problems. However recently, Thunderbird very often simply stops responding. Sometimes it just hangs up and sometimes the program bar at the top displays "Mozilla Thunderbird (Not Responding)". If I try to wait for it to respond, it literally hangs for several minutes before it begins to respond again, and often, it simply never starts responding again. It has simply gotten to the point where Thunderbird is practically unusable. All my other application software continues to work with no problems. It's just Thumderbird.

The version number in this submission may not be correct. I can't provide the real version number because of the hangups.

Any suggestions?

Since 3rd September 2026 Thunderbird opens a system integration window and then goes to not responding. I cannot access my emails through this software at all at the moment as there's no way past his pop up. Version 153.1.1, Windows 11 Home.

Starting today (September 3), ALL of my received emails are being put into the Spam folder instead of the Inbox.

FYI, I have been running Thunderbird (TB) for years and have not recently set up any new filters.

I'm currently running Thunderbird 64-bit version 155.0 under Windows 11 Home version 25H2. I am also running Bitdefender Total Security, but I have turned off its Antispam function, both under my usual Standard User account and the Admin account.

I have tried:

1. Going into TB Settings|Privacy & Security|Spam and clicking on "Reset Training Data." 2. After closing TB, I deleted the training.dat file in my TB profile folder and restarted TB. 3. Right-clicked on my Inbox and Spam folders and clicked on "Repair Folder." 4. Exited TB, copied my profile folder to an external HD, uninstalled TB and reinstalled TB after downloading from the official download site. 5. Rebooted my PC.

None of these approaches has worked to solve my problem.

Thanks for any help you can give.

For some reason all my emails contained in the inbox keep moving to the trash box by themselves. I have to manually move them back to the inbox. This includes read and unread messages. anyone know how to stop this? V 152.0 64 bit.

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

All of the incoming messages are going to Trash. This includes messages I have not indicated as trash. I get no new messages to my inbox. Started today, 09/04/2026.

For years I have been using Thunderbird and supporting with donations and one of the important uses is being able to preview .pdf files and then quickly highlight and copy information from the pdf such as an invoice number so I can paste it into another document.

Now I can not do this - Why?

I am running 154.0 (64-bit) on Windows 11 - not that this should matter - clearly the issue is the update has chanced how .pdf's can be accessed.

Other issue is printing the pdf only prints a blank page

Incredibly frustrating - what is the issue and how do I fix it?

I installed Thunderbird on my new laptop, then imported the profile from my old laptop

The main screen has, under "Inbox", folders for Drafts, Sent, Trash, Archive and Spam, which are being used by the program

Folders for Drafts, Sent and Trash also appear under "Local Folders" (along with Outbox) and these aren't being used by the program.

How do I get rid of these duplicate folders? "Spam" had a delete option, so that was easy, but the others don't.

I tried the two suggestions for a previous "Duplicates" question but they didn't resolve things.

Thank you

Logged into Thunderbird this morning. On current version. Noticed that the local trash folder had emails in it. I have not changed any of the multiple account setting. Send some test emails fro 2 accounts and they ended up in the local folder trash. What has happened. I want this redirection to stop. What other demons have been created by the current update. HOW CAN i fix this problem?

I downloaded the version on the site but I can't get it to accept my password all I get each time is this at the top of the box

Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI]

Just how am I supposed to understand what that means. I would be grateful for any help you can give I've been using Thunderbird for over 25 years without any problems, I had to reinstall Windows and now I've got this problem.

Hello All, all of a sudden I cannot send emails anymore. I do receive emails though. I have 4 accounts and none works. I went to account settings > outgoing ... all my accounts are set to SSL/TLS and below OAuth2. What goes into the Username field ... the email address or just my name? When I send a test email to myself the send window keeps going and going .. never sends BTW ... in Server Settings I have the same Authentication and Security as in Outgoing. Please help - I'm not getting anywhere. Also ... what goes into "Manage Identities"? ... just the specific email? or all four?

Thanks

Hello; I have been using Mozilla Thunderbird for many years on my PC and was wondering if I can start using my account on my Ipad or Iphone as yet?

I can print e-mail, but not the attachmnet since yesterday. So I contacted HP-support, but it is not the printer. The last attachment I printed was before the last update of thunderbird. What can i do?

I had Thunderbird on my Windows 10 computer. I bought a new Windows 11 computer and downloaded Thunderbird. When I try to set up my email account, I provide my full name (not my Thunderbird user name) and email address. The next screen has the message "Configuration found in Mozilla ISPDB ". I clicked on IMAP and hit continue. The next screen I type in my password for my Spectrum mail account. I have confirmed that the password works went I log onto the Spectrum website. The next screen has the Authentication error "Unable to log in at server. Probably wrong configuration, username or password.". I've also tried using my Thunderbird user name and Password instead of my full name and Spectrum password with the same results. I know my Thunderbird user name is correct but I can't be 100% sure that my Thunderbird password is correct.

I'm not sure if this matters but my email has the has the extension ----@socal.rr.com. This was assigned to me by my original email provider, which was Time Warner Cable. Spectrum bought Time Warner Cable a few years ago and I think Spectrum uses a different extension.

I have Win11, Thunderbird Windows MSIX packagethunderbird-MSIX - 1.0, and several accounts (The box below won't take anything past "Thunderbird Window.")

I'm looking for some way to make a different ring either for one of the accounts or for certain domains or for a subfolder -- any way that I'll know when something comes in from specific domains. The special ring(s) can be for each of the two domains or both of them. Can that be done?

Yesterday I had to change my Spectrum email - I have an old road runner email address and swapped over to spectrum.net server from the old server. In this process I had to update my password to access the server.

When I updated per the instructions from Spectrum I was able to do a normal download into my Thunderbird inbox. This triggered me having to input the new password. I did check the box to update the password and save it. After the one time download I cannot get Thunderbird to download emails. I can send emails with no problems but cannot download. No way can I get a download - it does not on initialization, at the set time nor with the manual request.

Spectrum is no help - their web mail works and it's my problem. I realize this is an old system, legacy and all that - anybody got a magic fix?

Any idea on how I messed this up?

Thanks.
