Forum der Gemeinschaft Thunderbird

Greetings,

I've lost the ability to receive e-mail, Suddenly Thunderbird just quits on me with no warning. Apparently I can still send mail but cannot receive. This is the second time this has happened to me in as many months. How do I fix it? How do I prevent it?

Thanx

Dear Support Team,

I am facing a recurring issue with the Attachment button in the Thunderbird Desktop application for the past few days.

When I click the Attachment button while composing an email, it does not respond or open the file selection window. However, I am able to attach files successfully by using drag and drop.

After some troubleshooting, I found that deleting the mail.compose.attach.dir preference from the Thunderbird Config Editor resolves the issue temporarily. Once I delete this preference, the Attachment button starts working normally again.

However, after some time, the same issue reappears, and I have to repeat the process of deleting mail.compose.attach.dir from the Config Editor.

Could you please advise on a permanent solution to prevent this issue from recurring? I would appreciate it if you could also let me know whether this is a known Thunderbird issue and if there is any recommended configuration change, update, or fix available.

Thank you for your assistance.

Have been receiving alert notification that my hawaiiantel..net account is temporarily unavailable. My email messages to that account are not being received and I'm unable to move email messages to the inbox of that account. Have been receiving these alerts for the past 3-4 days. is there a way to resolve this problem?

I have Thunderbird installed on Windows 11 along with Norton 360. Today, my connection to the AT&T e-mail server suddenly disconnected and I immediately got a pop-up notification that Norton detected a problem with a security certificate. When I inspected the details, it indicated that the certificate for inbound.att.net had expired (the range of valid dates on the certificate actually listed the current date as the last valid date). After several infuriating calls with AT&T support and Norton support, I figured out that simply disabling Norton e-mail protection allowed me to access my e-mail account.

Multiple web searches on similar issues suggested that since Thunderbird has its own certificate storage, fixing the problem involves locating the Norton certificate file and importing it using Thunderbird's certificate manager. Unfortunately, that solution appears to be applicable for first-time Thunderbird installation, and I when I tried it I was informed that the certificate was already installed. Another web search suggested that I should go to the Authorities tab and remove the entry for "Norton Email Protection". Unfortunately, the entry that I found was for "Norton Web/Mail Shield", which according to at least one source is not the same thing, so I am afraid to remove it.

So my question is has anyone else encountered this same problem, and is the correct approach to remove the Norton Web/Mail Shield authority before importing Norton's certificate file?

Thunderbird told me that I had to give the password of one of my email adresses again. So I added it but it did not work, so I changed my adress' password online and tried again, still nothing ; so I deleted my address from thunderbird and tried to ass it again but it still doesn't work

I checked all the previous infos, IMAPetc, everything is correct except in the end when I add the password (which is correct because I can access my email adress on the website with it), it does not work

I tried all the solutions I could find, like deactivating the "account hub" option, or getting rid of my antivirus, but nothing works...

when composing outbound email message ATTACH key is at top right hand corner of screen. If attachment is required and ATTCH key is clicked choice of File(s) or Webpage shows. If File(s) option is clicked Home -File Explorer comes up from which required file can be selected. This function has recently ceased to work. How can I reactivate the ATTACH function? Please assist, thank you, Chris

I am requesting that the update team consider providing an option for larger and permanent scroll bars. The current small, disappearing scroll bars require more accurate placement of the cursor than is easy and sometimes results in false signals to Thunderbird to scroll as you try to center the cursor. I know I spend several seconds messing with it each time I want to scroll up or down or just go to the next line as I'm reading. This may be a request to accommodate the elder community, who often has less fine motor control in their hands.

I can't get an attachment to an email message. When I select the 'attach' button, nothing happens. I recently cloned my C: drive and am concerned that something didn't get cloned properly

This morning I started getting this popup in lower right part of my screen every minute :

Mozilla ESR Thunderbird Connection to server inbound.att.net has been reset

It continues over and over as TB tries to get new messages.

Also, AVG Free antivirus is telling me it has identified a site certification problem. LOCATION: inbound.att.net (POP) Process: thunderbird.exe Detected by: Email Shield

In TB Help it says I'm currently on the esr uipdate channel .....whatever that means Whats the issue here? Can anyone help?

I received an email and when I responded to that I need to attach a document. I was unable to attach it. I went to another email and it also would not attach any document???

Just recently, the "Attach" button in the top right corner of emails in Thunderbird has stopped working. You can click it but it will not open a window to select a file to attach. Similarly, the yellow reminder bar will not allow attachments to be selected.

However, it is still possible to attach a file by dragging and dropping from an open older in Windows Explorer.

The version of Thunderbird I am running is Thunderbird 153.4.0esr (64-bit) [showing as up to date] running on OS Windows 11 Home Version 25H2.

I tried removing the button and then reinstating it (a fix suggested online) but this had no affect. I also checked in properties that the Run as Administrator box was not ticked.

Another fix suggested on line was to rename the file xulstore.json as xulstore.json.old, but this did not solve the problem either.

Any help in solving this problem would be appreciated. Thanks.

My eMail has worked fine for many years - until this morning.

 When I first tried to "get messages", I got a response, "connection to inbound.att.net server reset".
 I restarted Thunderbird, and then the computer (Windows 11), and when I tried again, I got, ""inbound.att.net (POP) .. certificate revoked".
 I can login to my ATT webmail, but I can't download eMail to my computer via Thunderbird.

... In my attempt to upload this question, I looked for the TB Version, but it said to update Thunderbird. I did so, not it is back to telling me "connection...reset"

 Please help!

Thunderbird (153.4.0esr (64-bit) ) does not display or let the user change its printer setting before launching print preview from the print command. If Thunderbird is set to choose a missing printer, it gets stuck trying to contact the missing device in order to prepare a print preview. It seems to be stuck forever, it does not seem to time out. There is no cancel button. If you close the document tab, you can permanently lose the document if it is a draft email, unless the email service saves it in a trash folder. The printer setting can be cleared if the user manages to learn how to display and clear the troubleshooting information.

Thunderbird needs to display the printer setting and permit the user to change it before launching the print preview operation. It needs to display a cancel button during the print preview operation.

Hi, I have Thunderbird installed and have been using it to do my email on a self hosted server and to connect to a google calendar account. This has been working for years, but now I'm finding when I accept a meeting invitation via email, its not being put through to the Google Calendar. I've reset the google calendar link a few time (deleted and created again from scratch). Its using the caldav interface to Google calendar. I'm also seeing this random message pop up (see uploaded image) - but there is no details on what to do. Anybody have any clues?
