The qr code displayed in the account transfer email from thunderbird is bigger than my pc screen. Snapping a picture with phone camera not possible. I employ visual accessibilities on pc as I am elderly and have tried to get emails to appear smaller. Cannot get entire qr image on screen.

I was locked out from yahoo completely but managed to reconnect with their web client today but Thunderbird still doesn't work. my connection is POP with my ports set as: inbound.att.net 995 outbound.att.net 465 when I test the connection under settings in Thunderbird reports: Successfully established a secure connection to inbound.att.net:995. Successfully established a secure connection to outbound.att.net:465. I was at Version 146.0.1 so I upgraded to 148 with no difference

Verwalte über Thunderbird mehrere Mailadressen, jedoch läßt sich keine dieser Mailadressen öffnen. Es kommt ständig die Mitteilunbg , 'Keine Nachricht gefunden' . Bei Neustart kommt die Mitteilung Thunderbird wird bereits ausgeführt, und dann erneute 'Keine Nachricht gefunden ' ... !???

I deleted my Thunderbird account and created a new one on the same computer. I used a Profile saved on my external hard drive. The address book info was replicated. The hierarchy of folders and their emails were not replicated in the left hand pane. Is there a way to retrieve those folders with their content? Please, I am not super techno-savvy, so take me step by step. Thank you.

My friend Ken has been using Thunderbird successfully for a long time. in the last 2 weeks, yahoo popups have shown up that prevent Thunderbird email usage. How do we get rid of them?

For the last two days, every time I start Thunderbird, a pop-up requests me to log in into Google Calendar. I have followed what little advice I can find:

• Unsubscribed/deleted all calendars
• Deleted all Gmail Accounts
• Deleted all saved passwords, and re-entered them only for my current email accounts.

How do I get rid of this irritating and unnecessary pop-up? I have updated to v128.14 but the problem persists.

Thanks in advance.

I receive the following error message: Not enough disk space to download new messages. Try deleting old mail, emptying the Trash, and compacting your mail folders and then try again.

I get the message when I want to download new emails. The suggestions to fix the problem DO NOT WORK. I cannot compact, the Trash is empty and I know there is GB's of space on my C: drive, which contains all Windows software. What to do?

Can I use thunderbird with multiple accounts on multiple PC's and stay synchronised?

I have two PC's i want to set up - it seems like i have to create a new account for a second PC rather than pick up the account set up from the first PC.

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 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?

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.)

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?

How can I get the "send" button back in my menu. I am not offline. I am receiving messages and can write and save messages to draft but there is no SEND button in my menu anywhere to enable me to send messages out.
