I've got a Fastmail account, and have set up CardDav according to Fastmail's guide to get set up with Thunderbird.

Once my contacts synced, I was unable to see my contact lists in the Thunderbird contacts sidebar, nor can I add a list (the button is greyed out). Is this a known issue? Is it Fastmail specific, or a CardDav thing?

Running macOS 14.3, Thunderbird 115.9.0

I am an e-mail packrat.... I have a pop e-mail but keep years and years worth of old e-mails (inbound and outbound) some with big attachments. My backup for the few e-mail accounts I have within my profile is approx 13 gigs. I've moved machines... and currently running Ventura on my imac.

I have to force-quit all the time to get my e-mail working again. It hangs-up.... sometimes will recover... but then... I type a few words or maybe sentences... and back to HANGING-UP again. Sometimes after a Force-Quit... it will behave for awhile. Other times... it takes 4-5-6 force quits in a row to get the program working again. Been having these issues for months... and have taken out all the add-ons etc.... HELP... pulling my hair out! Thanks

An IMAP mail system is configured on a server running Debian 12. While there are never any problems via webmail, reception and sending work occasionally via Thunderbird 115.9. Even in "Troubleshooting Mode" it doesn't work. The server has good hardware characteristics and there are no applications that can slow it down, nor do I think it is a firewall problem or incorrect parameters otherwise it would never work. The error is related to timeout reaching the server. What can I check to find out where the problem is?

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.

Hello

Yesterday there was update in Thunderbird and went well. But today, Thunderbird suddenly asking for credentials and then it went totally blank as in screenshot. There is nothing at all. But incoming mails are still showing up in windows notification and it can be opened as new tab of Thunderbird. I have been searching the possible cause and solution from forum and internet, but no luck. Can someone please help me about this ?

About 3-4 days ago, images no longer appeared inline and there isn't a button to show images, just an empty box. My T'bird is set to auto update, so not sure if an update caused this? Not sure if it's related, but at the same time, my rss feeds stopped due to "invalid security certificates." I did not make any changes to previous settings. Thanks for any suggestions!

Yesterday my Thunderbird was sending but NOT saving sent messages. I was receiving all messages. Today, however, I CANNOT RECEIVE or SEND messages. I have used Thunderbird on this computer for years . . . what has happened?

I would appreciate your help. Win Dawson

A while ago, I had to work offline so I had TB download my Gmail account messages. Now I no longer want these messages to be stored locally, because the Thunderbird folder is up to 10Gb, so I unchecked the box in Synchronization for 'Keep messages in all folders for this account on this computer'. I was hoping the TB would subsequently purge the offline folders, but apparently not. Is there a way to clean out the folders without affecting my online Gmail folders as in Inbox and Sent folders?

I am asked to get a new password from my mail server (AOL) every day when trying to send messages. Have to log on to AOL, ask for app password, enter at Thunderbird. DAILY!

how can i stop thunderbird from interacting with windows defender anti virus scan? when ever i download or delete emails i get a few seconds of "not responding " and the whole computer is non responsive. i used to be able to turn off real time scan in security and it would work for a day and then windows would enable it again. now since the last upgrade windows isnt allowing me that option any more. solutions?

Thunderbird on my top of the range Win11 laptop was working perfectly until it self-updated to 115.10.1 a couple of days ago. Accessing messages already in the various folder is fast as usual. Unfortunately anything like deleting, downloading a new message is excruciatingly slow : several seconds to click and delete in the inbox. Several seconds to access a message just downloaded. The first time it happened I had a whole bunch of messages deleted because the I kept clicking when I saw no action. It seems to me like it has problem updating the messages in the inbox. Very painful for something that was working so well.

I'm trying to use Thunderbird to access my work emails directly. They use Outlook Office 365, which I can use the webmail version of just fine, but a year ago they upgraded to Oauth2 and MFA and for the life of me I cannot get any version of Thunderbord to work with it anymore. I can send an email, but I can access any email on the server. Weirder still is the error console message suggest the program thinks I cancelled my password entry;

"Loading failed for the <script> with source “chrome://global/content/netError.js”. neterror:128:4

NS_ERROR_ABORT: User canceled primary password entry"

I received the new version, Version 115.10.1, and the next morning I have emails going to other folders, 1261 junk files that had already been received over maybe the past week or so all received again AND not filtered to the junk folder but rather to the inbox. 2 emails moved from inbox to another folder. Train wreck.

Hi,

Just updated to TB 115.10.1 and right on update it now fails to show the most recent emails in the inbox, They are there as I can scroll up to them but it no longer does that on it's own when opening and downloading the latest.

Any suggestions to get it back to normal operating condition?

Yesterday, whenever I tried to open Thunderbird I got a This app will not open on your PC Windows error, and Word and Excel would not work. Apparently I had some Windows 10 problems which I was able to repair with Windows Resource Protection. Thunderbird now runs, but all 2000 of my Inbox messages do not appear. If I open my Mail folder in my Profile, I see the four folders inbound.att.net, inbound.att-1.net, inbound.att-2.net, and inbound.att-3.net The size of each of these inbound Mail folders is 5MB, 9.8GB, 38MB and 20MB. So, all of the missing Inbox emails are in the inbound.att-1.net folder but they don't show up. I tried deleting the .msf file. That didn't help.

Does anyone have any suggestions?

My Thunderbird email on my PC will only open intermittently in the last few days. Re-starting my computer sometimes helps, but only temporarily. There are no error messages- just nothing happens. I am still able to access email on other devices - just not on PC - which I use a lot. I'd be grateful for ideas of how to fix this. Thank you, Pam Rycroft

Whenever I open my Thunderbird email application .. its constantly asking me to re enter all the passwords for the email accounts I have within the app .. I even select to save the password but its constantly asking me to enter it than i enter it and a minute later again it loses sync with the server and i have to re enter it again and again for each email I have linked within the app
