Thunderbird Community Forum

When I attempt to write/ reply/ reply all/ forward, the toolbar at top shows only the slanted pen symbol and "Write -- nothing below. So no "Send" button. The full toolbar that I am trying to recover is attached which I copied from a second computer. When I write click that "Write" bar at the top, noting in the drop down menu had any effect. Help/About says I am "up to date" running 153.1.0esr (64 bit)

This is the message I get when I try to send a message. Sending of the message failed. An error occurred while sending mail. The mail server responded: <budguinn@charter.net> sender rejected. Please verify that your email address is correct in your account settings and try again.

I have included a screen shot of my server settings.

Windows 11 Sending, but not receiving e-mails in two OAuth addresses (one university account, one personalised domain gmail) Can't find 'Incoming Server Settings' to check if they are correct Have selected "manual configuration flow" and restarted Thunderbird

Hi, I just installed Thunderbird on a new computer and was super happy about how easy the setup has become for multiple e-mail addresses - however, I have two addresses where I can send, but not recieve e-mails. One is a university e-mail and one a personalised domain gmail - I used both without trouble in Thunderbird on my previous computer. They are both OAuth and the Outgoing Server Settings are correct, but I cannot find where to adjust Incoming Server settings. I've selected "manual configuration flow" and restarted Thunderbird, but still can't see anything new. Where do I find Incoming Server settings now? Thank you for your help,

I am trying to run Thunderbird on my laptop. I currently have it on my PC and my Phone. I just installed Thunderbird on my laptop and zipped my profile (60GB). I tried to open the zip file to make sure it was good. I could not open it, so i did not transfer it. I was looking for an easy way to get all my email accounts and passwords onto my Laptop. I would appreciate any help. Thanks! Kelly

Thunderbird not connecting to server. It says timds out and an error occurred connecting to mobile.charter.net. I can neither send or receive emails. This started 8/20/2026

Hi, Hoping I can get some help here, I couldn't find an answer in the search topics.

I have lost a few local subfolders. First the subfolders lost the emails contained in them and then the subfolders themselves disappeared.

I renamed the main folder just removing the year from the folder name and not long after that the above happened.

I have tried the following:

• Searching the help topics • Searching the forum • Closing reopening Thunderbird • I removed .msf files and restarted Thunderbird

I am not sure what I can do now.

Thanks in advance for any help.

With the new meadow update when either replying to a message or selecting new message there is no command menu bar to send save as draft etc.... tried several of the commands an setting changes but nothing seems to work - can do cntrl+enter to send and that s about it....

Ok small issue but annoying, I'm using a desktop install of thunderbird,and upto the last few days it has worked fine,I was using a custom sound file to inform of new emails and that was working fine,but yesterday I noticed that no sound was being played when a new email arrived,I've changed it back to default and that is not working either.

Anyone any ideas why it's not working or how to get it back to a working basis?

In the last month or 2, when I delete an email it does not show in the trash folder. I can wait from 5 minutes to even the next time I reboot my puter to finally see it it trash. Sometimes it sends it to the all mail or important folder instead of trash. And if I delete from there, it still takes tons of time to end up in the trash folder...if it even gets there. This seems to be getting worse by the day. I have clicked repair folder, no change, I have cleared Thunderbird's cache, no change. It's also now taking way too much time to load an email that contains a picture. This happens with at least 3 of these gmails. I'm at a loss here and extremely frustrated and about to change these gmails from imap to pop. win10 and TB is up to date. But it doesn't compact folders as much as it used to either. 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.

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.

We are facing a critical printing issue with Thunderbird 154.0 (64-bit).

Emails are not printing from Thunderbird and are coming out as completely blank pages. However, the same email/file prints perfectly when saved to a folder and printed from there. This confirms that the printer is working properly and the issue is specifically with Thunderbird.

The problem is affecting multiple systems in our office as well as our Ahmedabad branch, which is seriously impacting our daily work.

This issue requires immediate attention. Please investigate and provide a solution/workaround at the earliest.

I've found out that on both Linux and Windows since the last update (154.0), the PDFs printed directly from the Thunderbird PDF viewer, prints out blank PDF.

To recreate this, open a PDF attachment in an email, simple double click on it, in the top right corner on the tool bar, press the little printer icon, choose either "Save as PDF" or print to the actual printer, in both cases, you will get one blank PDF page.

Is it possible to import to, or display email messages, in Thunderbird, which are stored in a Becky Internet Mail program folder (https://www.rimarts.co.jp/becky.htm), please?

Thanks
