Trying to connect to my AOL mail account on a laptop w/ win 10 & thunderbird returns the message not a valid certificate. AOL support said change the password to reset the account, which I did. Now all I get is " Host contacted, sending login info " & it the server connection times out. I can log into my AOL account with firefox. Any help will be greatly appreciated !!

Since updating Thunderbird 64 bit to v147.0.2, then to v148.0 (1st March 2026, just now), requesting the display of 'Unified Folders' (in Folder Modes) does not populate the unified Inbox with messages from any of my eight registered email inbox sources. The individual inboxes with their contents can be displayed below, but not in the unified Inbox.

Since being introduced several versions ago, I have found this feature very useful when checking my various received emails, and it is frustrating to be without it.

Can anyone suggest what I may or may not be doing to get this feature to work any more? I have been all through Settings, but cannot find anything relevant to this problem.

Cheers, Sam

I am trying to re-install Thunderbird on my wife's old Gateway desktop. I downloaded version 115.18.0 and tried to install it, but get a message saying it can't be installed because my OS is 32 bit. I thought the SuperNova would work for both 64 and 32 bit OS platforms. (It does work on my Toshiba laptop, which is a 64 bit Win 7 machine.) If this version of Thunderbird will not work, what about the last version that will. It was installed years ago. Thanks, Peter

I am installing Tbird on a Windows 10 instance that I am recovering from backup. There is a default profile that contains a folder for a user in an IMAP domain that no longer exists. Tbird won't start and just spins with a message about a missing IMAP user.

I copied the profile to another backup folder. And then uninstalled and re-installed TB. The "AppData > Roaming > Thunderbird > Profiles" folder(s) are still there but empty. When I start TB it says: "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." The old email is not important now. Should I delete more folders in AppData, or what should I do next?

Thunderbird 143.0.1 eclipse.

Quite recently I noticed that, in the list of folders, I see 2 "Junk" folders.

On looking at the properties for 1 Junk folder the location is shown as "imap://*********%40gmail.com@imap.gmail.com/Junk",

but properties for the other shown as Junk locates as "imap://*********%40gmail.com@imap.gmail.com/Spam".

I've tried renaming that folder in Thunderbird to Spam but the change doesn't take effect.

What went wrong, and more importantly how can I rename it to see it as "Spam"?

tnx.

For the last few days my Unified Inbox which is fed by three of my email accounts stopped displaying incoming emails in the Unified Inbox folder. I am running Thunderbird Desktop version 140.2.1esr | Released September 2, 2025 on a Win 11 PC. The incoming emails show up in their Thunderbird accounts OK in their own Thunderbird Inboxes but they no longer also show up in my Unified Inbox. I did not change any setttings that I know of but the Unified Inbox just stopper working properly.

I have gone to the Unified Inbox's Properties and deselected each individual inbox and then selected them and no change. I deleted the cach and no change. The Unifed Inbox is set to "Match all messages."

I am guessing it is a bug in the latest Thunderbird update but perhaps someone can offer a fix I have not tried yet. Thank you!

I want to access an Outlook.com email. It has 2-step verification. It also says I may be missing a domain name before the email. Not sure what that is. DomainName/myemailname@outlook.com.

Updated to 148.0 this morning and now none of my google calendars are population the calendar. I am clueless as to why. Tried deleting them and re-adding them in - Not working. If this can't be fixed I am done with Thunderbird. Kind of sick of everything breaking with updates with no warnings.

A "send later" button came up one morning instead of the usual "send" button. When I clicked on the write button to see where the "send" button was, several choices came up but when I clicked on the "write" choice I lost the other choices and now can't get back to the original write button and still no "send" button appears anywhere on the menu. I can save messages to Draft but still can't actually send them. I can still receive emails, just can't send them! Help!

Updating my Address Book in Thunderbird v148. The darned thing does not permit two people to have the same email address or phone number - pain in the "A" to say the least !

Okay, I currently have two issues going on, both repercussions from transferring Thunderbird to my new computer. I'll limit this post to one issue!

My transfer to the new computer was not taking; followed instructions but no profiles were loading. I thought that perhaps this was due to my initial problematic installation of T-bird decades ago, where I eventually wound up with a choose-user-profile panel that worked fine with its default setting...so I lived with that easily (see image). Thinking that this was causing the inability to load profiles on the new machine, I tested whether I could delete the never-used profiles in that panel. After just one deletion, that resulted in the "Couldn't load XPCOM" error described here: https://support.mozilla.org/en-US/questions/1360766 Following the instructions on that page to do a repair installation (to the letter), starting T-bird now results in the attached "profile missing or inaccessible" message.

Please advise: Am I doomed?

Thanks for any honest advice. (yes, my Thunderbird installation is big: seven or eight addresses, many local folders, a large history and archives.)

Issue

Thunderbird fails to wrap long lines of HTML-formatted text that is wrapped in a <pre> tag. This behavior is consistent in both the email viewer when viewing received emails, as well as in the email composer when writing an email containing preformatted text.

What I tried

1. Make all settings of config editor that contain the word wrap as true 2. make a userContent.css stylesheet within the chrome directory within the profile directory.

Question

How do I post the offending HTML code (and the CSS file I tried) on this forum?

How do I force Thunderbird to wrap preformatted text?

I've been using color settings in userChrome.css to set the colors for the threads and folder panes... I obtained these settings from a discussion in the Thunderbird Beta mailing list, back in 2023. Here are my current settings:

root {

 /* Force BG in unthemed folder */
 --foldertree-background: #A99B92 !important;
 /* Force BG in threads */
 --tree-view-bg: #A99B92 !important;
 /* Force black text in threads */
 --tree-view-color: #000 !important;

} /* Position Menu Bar above Unified Toolbar */

1. toolbar-menubar { order: -1 !important;}

However, after the most recent beta update, the tree-view settings are no longer working, and I'm stuck once again with the ghastly Bright White background... see the attached image; note that the foldertree setting is still working though...

What do I need to do, to get this code working again? or is this a bug in the current beta?

Hi, I just noticed that my computer has been infected by a trojan called "HEUR:Trojan.VBS.SAgent.gen", and I can't remove it via Kapersky...The trojan is found in the inbox file in Thunderbird. So it's not a file that I can remove (it's all code). Kapersky stated that these two files are the source of the Trojan (they are not found as an e-mail attachment in my inbox, it's all code in the inbox file in Thunderbird):

P000009384:Emirates_Marble-pdf.gz and P000009384:Emirates_Marble-pdf.vbs

So I'm simply wondering how I should go about to remove this trojan from my computer?
