Thunderbird Support Forum

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

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.

My wife and I each have our own Thunderbird accounts. They were created a long time ago, at different times. I’m pretty sure that they were not set up identically. She has recently experienced a problem: the number of new emails downloaded (as shown in the lower left corner of the screen) doesn’t match with the number of new and unread emails listed in the Inbox (the emails shown in boldface). Something else, though I think related: In the upper left corner of the screen, on the same line as the word Inbox, is a small circle with a number inside. I think that number gives the number of unread emails in the Inbox. Her number shows 20 but the actual number (boldface) is 15. Is this a serious problem? Is it a problem at all? If so, how to fix it? Thanks.

When receiving emails they appear as normal but in the background is another email of a couple of pages which has sender and receiver details at the top then lines of letters making no sense for the rest of the message.

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 have set up my own domain guytec.org using Namecheap. The alias for email is tguy. I have pointed this new email to my gmail address. I can receive emails into my thunderbird Gmail box from tguy@guytec.org. I want to write emails with sent from tguy@guytec.org showing? How??

Since installing Ubuntu 23.10 on my new desktop pc, Thunderbird is failing to see the account details in .thunderbird I copied all the files from my backup into a new account directory (/home/cfi/.thunderbird/y4xyxmli.default), a technique that has worked many times in the past, but not this time. Previously, thunderbird has simply taken the settings from the backed up files and used those to connect to my organisation's mail server. Any ideas? How can I force Thunderbird to read the old account settings?

Many thanks.

Dzień Dobry

Poczta Thunderbird nie ściągą nowych wiadomości, usuwane teraz stare, wracają do folderów głównych. Przy odbieraniu wiadomości pojawia się komunikat jak na zdjęciu. Ostatnia wiadomość pobrano ok. 100razy.

Hi. When replying to an e-mail, Thunderbird has started to place to input cursor in the TO field instead of the message text field (in this case it should be before the answered text).

Any ideas? BR Johnny

When I delete an email, it usually goes to the trash, so I can find it again. Now the emails are deleted permanently and disappear. How can I keep my emails in the trash? Sincerely Helle

Using 115.10.1 and POP on Windows 10 Pro (v. 22H2) with just the Windows built-in virus protection enabled (but App or Browser Control is disabled). Platform seems stable, no evidence of nefarious services noted in task manager.

Realized the emails in InBox from a couple of days ago (and going back decades) were blank or had mismatched headers to content. Figured an index problem. Ran the Repair under 'InBox' folder Properties, and only a few of the most recent emails remain - all duplicates of which I had sorted into other folders.

All the other folders are fine - just my InBox got wiped! Looked in the Thunderbird folder under profiles and saw the above captioned with a time-stamp that captures the approximate time this went down - occum's razor. I did not initiate any update to Thunderbird.

Walking on eggshells and very nervous, we're talking thousands of emails, what is the recommended recovery of the InBox (after I attempt to backup what I have left). Thanks!

Every few days, the index pane of some folder gets corrupted. Repair (right-click, Properties, Repair Folder) fixes it. Then a few days later this repeats, with a different folder. I have three IMAP accounts and this occurs on more than one of them.

Any suggestion for finding and fixing the underlying problem?

I am attempting to transition to Thunderbird. I have become quickly familiar with the HTML/CSS underlying the UI, and with the older userChrome.css structure for personal customization.

However, I can not figure out how to change the default background color of the message composition window -- which exists in a separate window from the main message viewer window -- from #2a2a2e to basic white.

Cracking open a copy of omni.ja in the app package, the only ID that I can find that seem to possibly be relevant is #messageArea, found in the following .css files:

chrome/classic/skin/classic/messenger/messageQuotes.css chrome/classic/skin/classic/messenger/shared/editorContent.css chrome/classic/skin/classic/messenger/shared/messengercompose.css

I have tried to override the default #2a2a2e color of the message composition area in my userChrome.css file, but to no success. (By contrast, it was easy to change the background color of the message viewing area with #messagePane)

I have tried the obvious step of changing the background color to white in the color settings option. Even after multiple app restarts, this setting does not affect the dark grey default background of the composition window.

Is there a name to this window div and a class or ID that i could access and customize through my userChrome.css file?

Thanks!
