Thunderbird Support Forum

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it.

It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

I am using TBird v115.10.1 and I need to be able to EXPORT my contacts to an Excel .CSV file. My version of TBird does not offer any customisation of the Export function.

if I schedule a meeting locally for 9am some attendees receive the meeting scheduled at 8am (1 hour earlier than actual). I have checked my thunderbird date and time settings and they are correct. The attendees claim their settings are correct but between the 2 systems (Thunderbird and Outlook) there is an hour discrepancy. This is causing clients to miss my meetings. Please assist.

For past 24 hours only, I have been unable to open email attachments. v115.7.0, however last update was 31/01 and has worked perfectly until now. Still use Windows 10.

Double clicking on attachments does nothing, other than popup software option for formats without specified defaults. Either way, no indication that attachment is opening.

"Save as" is saving attachment document to target folder, however trying to open these errors, suggesting document is corrupted or in incorrect format.

Have tried restarting system to no effect; likewise error continuing in troubleshoot mode. Cannot see any obvious settings that would impact this, nor have I consciously altered any of these.

I'm certain this may be an easy fix, or my own error, but this is eluding me.

Hi, I have had Thunderbird on my Windows 10 laptop successfully for many years. Today I added a new email account, but then Thunderbird kept losing connection. I thought I'd try uninstalling and re-installing it, but now I get the message that it can't be installed on my laptop. Anyone know how I can get round this?

bij het importeren van adressen is het misgelopen. Er waren een 90 tal adressen en na de bewerking vermeldt het systeem een 2700 adressen. de teksten waren niet leesbaar: alle letters dooreen. Die kan ik nu niet verwijderen

After updating to TB 115.5.2, we keep getting the following error message when we try to send or forward an email: Sending of the message failed. An error occurred while sending mail. The server is not responded. No such domain at this location. Please check message recipient "xxxxx@gmail.com" and try again. I get this error on all emails we try to send. We get this same error on my spouse's computer also that we use Thunderbird with. I have already checked settings with my ISP and the POP settings are correct. We can use other mail servers such as outlook.com and gmail.com using Thunderbird. ISP is cis broadband. have checked firewall, have uninstalled Thunderbird and re-installed without solution to problem. ISP has checked port to make sure it is not blocked.

incoming emails do not seem to be effected.

Hello, It's there any option/setting in mozilla thunderbird for drag and drop emails to local drive folder and save them under another filename that the standard "Subject" name? I don't know if i'm clearly enough, that's why i want to make a briefly description of the operation i want and the way the emails i want to appear in my folder. I drag and drop an email to my folder and this email has the filename represented by the "Subject" of that email. Can i change the way emails are saved ? Or can i drag and drop emails from one sender in separate folder ?

Back in 2015 someone asked about the fact that emails are not marked "as read" once opened but I don't think the answer was ever fully given. They were told: "This option has always been available and I use it. via Menu Bar Tools > Options > Advanced > Reading & Display or via menu icon menu icon > Options > Options > Advanced > Reading & Display select: 'automatically mark messages as read' Select: 'Immediately on display' click on OK When you select/left click an email in the list, it will auto open and display in the Message Pane below the list. If you use double click, it will auto open in a new tab or window depending upon what you selected. In bth instances the message will be immediately marked as read." Here's my problem with that .... I don't use the "Message Pane", I don't like it. I have my incoming messages set at "table view" and they are all just listed down the page by date. I don't want to see what's in the email until I actually open it....but, once I open it and read it when I close out of it the email still stays BOLD in the list....this didn't used to happen, once I read the email the BOLD went away. When I use the "automatically mark message as read immediately on display" then new emails are not in BOLD so I can't tell if they've been read or not. Bottom line, is there a way to have messages marked "read" AFTER they are opened WITHOUT using the message pane??

I had a huge problem with M Outlook. In addition it has locked me out of my Office 365 package and I'm not getting help or support. Luckily I had backup completed before the problem. I changed to Thunderbird (using pop3), which I find very good. The back up is approx 8 GB but with many duplicates which I need to clean up. When I click import it seems to limit the file size to 2 GB. How can I import this backup file into Thunderbird to enable me to access the emails, clean up the many many duplicates and reduce the size? I await help, Thanks in advance

I had emptied my spam and junk folders but unfortunately I had marked up one email address as such which I need to undue, but I can't find where the list is. Where do I find it please?

Most of my emails are going to trash, once in a while I may get one in my inbox, not very often. I now just go to trash for my emails, I am not very tech good but have tried and my son also tried, but we couldn't fix it, we probably may it worse. So I am coping by using trash as my inbox. I know this is not a permanent solution and would very much like to know what I did wrong and get it fixed so I won;t screw it up again. Thank you for your time.

I can't open my Excel attachments in ThunderBird.

Is there a setting I need to open. The one I use by default only gives me word, wordpad options. or choose my own, which is still word and wordpad.

Thanks for any help.
