How do I migrate the old Thunderbird profile to the new Thunderbird? Background: Up until mid-Jan 2024 I was using Thunderbird on Windows 7. In mid-Jan I did a "clean" install of Windows and installed Thunderbird. Due to a corrupted Windows installation, I had to do another "clean" install of Windows 10 Pro. Today I installed Thunderbird version 115.9.0. Everything went well. However, I don't have access to my old - pre-mid Jan profile - which has e-mails and contacts I need to access. Here's my setup: Thunderbird installed in D:\Thunderbird New Thunderbird profile is in M:\Thunderbird Old Thunderbird profile is in M:\Thunderbird-OLD

How do I migrate/import the old messages, address book/contacts, and find out which extension I had installed?

Thanks.

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

I have been working fine with Thunderbird, but today it won't start up. It asks my master password, but then it doesn't show the screen with my email accounts / emails.. In task manager I have two lines with Thunderbird, but no activity. I tried to re install (without uninstall as I don't want to lose my emails), but that didn't change anything. Not sure what I can do.

How does one enable calendars in Thunderbird version 115.8.0? When I click the calendar icon on the left of the page, I get a calendar displayed but it has a message highlighted in yellow that says: "All calendars are currently disabled. Enable an existing calendar or add a new one to create or add events."

I cannot find anything in settings or elsewhere to enable calendars.

TIA

When doing somethings in Thunderbird, like setting up or changing message filters, a new window appears on the screen with the options. However this window (and others like it) are often bigger than the screen size. (I use an old 1280x1024 screen as I am sight impaired, but even ona full size screen this can happen.)

The problem is that these windows are not adjustable in size. If the button you require is off thee screen. it is not possible to click on it. This makes configuration very hard, especially if it is the Submit button.

Is there any easy solution? There are many times when this can happen and adjusting the default text size at the system level does not help. When the window displayed is too large and you cannot shrink it or move it enough to display the buttons you want.

Thanks for any help.

My office is running Thunderbird 115. I recently changed the password. This seemed to work OK. But on restarting TB I found the new password had not been stored. The Password Manager display is empty, so I cannot edit anything, nor can I insert a new entry into the Manager. I want to store the current password. How do I do this?

Everytime Thunderbird is executed a separate and new instance of the 'Thunderbird Privacy Notice' tab is opened. If the tab is not closed it will re-appear when Thunderbird is opened at a later point along with another 'Thunderbird Privacy Notice' tab. In other words, there can be multiple tabs of the Privacy Notice unless it is closed upon every instantiation of Thunderbird. How does one prevent this tab from replicating itself upon every startup? Thanks in advance for any assistance.

I have used Thunderbird for many years without a issue. But as of a couple days ago I have been getting errors when I open Thunderbird. 1) It always ask me to login even after I save the password to always login. 2) I get this message: "Login to server imap.comcast.net with username caulkerguy@comcast.net failed." 3) Then I get this error message "Alert from account caulkerguy@comcast.net 1014." I have checked all my Server settings and all are correct as per your online settings. I have searched the web and have not found any fixes. Are there any fixes or work arounds? I would hate to stop using Thunderbird as I really like it! I have included 2 screenshots.Thanks for any and all help! Mike: caulkerguy@comcast.net or caulkerguy@gmail.com

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

I really am getting fed-up with Thunderbird which is getting increasingly user unfriendly and more and more geekified, e.g. the enforced belief on users that every user wants threading. To add to the gneral irritation, half a dozen emails have suddenly vanished from the folder they had been moved to.

Here's what happened.

1. The emails were moved from the iinbox to the folder.

2. They were unthreaded.

3. They then disappeared.

A search has not found them and opening and checking all folders has not found them.

So, two questions:

1, Where are they?

2. How do I get them back?

I have 6 email accounts and only 1 is a live.com email. That is the only account that keeps popping up a password error when I open Thunderbird. All settings are same same, full username with @live.com, SSL/TLS,norm pass and so on. Some days no issue grabbing emails ( no password prob ) then starts having issues, and I never changed anything. Any recommendations to resolve?

Upon reopening Thunderbird mail today, I find that the latest update does not allow emails to be opened in a new window with one-click. Clicking on an email launches the message in a new tab instead of a window. Why create a new issue like this? DUMB . . . please fix.

When composing a new message (in other words, not replying to a message) I want them to always show the default email address, the one corresponding to the top account. The field "Outgoing Server (SMTP)" shows (Default), and ordinarily it works fine, but occasionally it will use one of the other email addresses. In reading your responses to other questions I've seen that the default address is only used when TB can't figure out which address to use. Is there some way I can tell TB to ALWAYS use the default address when composing a new message?

I wish to try K-9 Mail on my Android - eventually I want Thunderbird. When I start K-9 it offers me "IMPORT SETTINGS" and then says CHOOSE FILE. What file(s) do I need to bring over from my Thunderbird profile to get 1. the address book(s) and 2. the email account data?

My newly updated Thunderbird has had the "Get new messages" and "Write" buttons replaced with a cloud symbol and a "New message" button. These are not as intuitive as the old ones and in the case of "New message" seemed more likely to be the new "Get new messages" button - but it isn't. Is there a way to restore the old buttons which were clear in their meaning, or at least to customise the new buttons with their old function text? I've tried playing around with the customising button options but apart from being able to add a Get messages button to the very top bar (where I would never think to look for functions other than to minimise or close the window) I cant see how to replace the new and confusing buttons or add some helpful text to the cloud symbol button. Thanks
