When I print my emails and sometime view them I appear to have multiple lines of programme text (see attached) The text is also very small. Being new to Thunderbird can you tell me what settings I have wrong.

I use 128.7.1esr (64-bit) on Windows 11 23H2. OS Name Microsoft Windows 11 Home Version 10.0.22631 Build 22631 I use two monitors: Monitor 1 is physically straight in front of me, and Monitor 2 is to the left, so in Settings > System > Display the box on the right is numbered 1, and the box on the left is numbered 2.

Since the latest TB update, each time I switch on the PC in the morning, TB (and FF) open on Monitor 2, even though I closed them down on Monitor 1 the previous night. This behaviour used to happen occasionally, now it seems to happen every time. Also, occasionally during the day, the TB Reminders window will jump to Monitor 2 while it's minimised.

I suppose the first question is - is this a TB/FF problem or a Windows problem? I'm thinking it must be a TB/FF problem, because this behaviour only seems to be happening with them.

Any suggestions would be welcome.

I'm trying to restore my Thunderbird mailboxes from my old (essentially dead) computer's backup to a new computer. My first attempt failed. I need to understand what went wrong and how to correct it.

I installed Thunderbird on the new computer and used Profile Manager to create a profile in the location where I want to keep it (in the Documents folder, to simplify backup). Then I found the place where the mailboxes were kept and copied my old mailboxes there from the backup.

Then I started Thunderbird. Instead of displaying my old Inbox and a list of mailboxes, it displayed a screen that prompted me to define my email account. OK, that's fair; if the account information wasn't in the files I copied, Thunderbird would have to do that. After I defined the accounts (there are three), I quit and restarted Thunderbird, and it displayed my Inbox and mailboxes.

But not quite as I expected. I expected to see the mail that was on the old computer when I last backed it up. Then I planned to download mail to get everything that came in after that. Instead I found that Thunderbird had erased everything I copied over, then downloaded the new mail without me asking it to.

Now what? The new mail is still on the server, so I can repeat the whole process if I have to. First, though, I need to understand what went wrong.

Owing to a price rise in MS Office, I had been looking to move to free software. Unfortunately for email this isn't working. I have downloaded Thunderbird and have tried to transfer my Outlook data there. I started two weeks ago and on average believe the process has been running a few hours a day, for much of the time when I look occupying 0% of CPU capacity, and most of the time not rising above 1%. The import has been stuck at 33% for that time, which I assume means that it imported Accounts and Settings or Address Books quickly and is taking a very long time to import Mail Messages. (It imported the couple of month's worth on webmail quite quickly.) Likely this is owing to the size of the Outlook file, 5 GB. Does this essentially make the transfer impossible? For how large a file could Thunderbird do a successful import?

Hi,

I set up my email accounts using POP3. I now realize I should have set them up using IMAP. Since I originally set things up using POP3, all my emails have been downloaded to my computer, and have been deleted from my provider's server. I have now created a new email account using IMAP. Is there a way to import the emails from the POP3 Thunderbird folder, into my newly created IMAP folder?

I have a custom email that I use for work and I was not able to get it working on Thunderbird. When I add the email/password, it detects the settings and then says it cannot confirm the password.

To workaround this, I only add the email, and then when it detects settings, it asks me to input the password. And when I do that, it adds the account and attempts to read my incoming STMP server. I get an error that it times out. And when I try to send emails, it says it cannot access the outgoing STMP.

I use cpanel and when I access my email via roundcube, it shows me my messages. I have cloudflare set up via namecheap with the correct DNS records. My other email clients (gmail/outlook) work fine. I have reinstalled thunderbird so Im not sure what else I can do

I have an e-mail account at work that goes through gmail. So how do I set up Thunderbird to access it? I have tried many times.

Let's say I have the following:

Full Name: Billy Budd E-mail address: [edited] @acme.com password: [edited]

I access this account though gmail. So how do I set up this account in Thunderbird so I can get all those e-mails and attachments on my local computer?

Thanks in advance.

Hello helpful community, Yesterday after first updating my mac ios, I updated Thunderbird (as directed) on my macbook pro and discovered that my local folders are gone. I now have version 128.7.0esr. I have read other conversations here about this problem but they are WAY over my head, and seem to do with PCs. Can you help me restore my local folders with instructions I can hopefully understand? Thank you!

I am receiving e-mails minus any graphics, such as those in 'WHICH' magazine articles or other advertising messages. Have I accedentally deleted or altered a setting somewhere?

Have attahed a screenshot of an advert from a company IJT Direct re a printer as an example.

Hello, I did just make a clean reinstallation of Thunderbird and while going through the setting I have notices that at Passwords / Save Passwords / `Show Passwords` my Account Passwords can be access with less effort.

My question now is, why is this even a feature?

In my mind, this should be by default off. Or at least informed me at the first account setup that my passwords are visible in the Settings, and if I want to set up a Master Password as well.

Is there an option to have the Button `Show Password` disable? Or if a Master Password have to be, then set it for only access `Show Password` but not for the login in to Thunderbird.

How do i change the highlight color of line items in my inbox? I just installed the program on a new computer. It is showing a pink color in my INBOX and want to change to blue. Thank you

I am looking at my email. I open one message into a tab on day 1. I leave the tab open. I do this again for two days. I now have three tables open. They are in the order:

Inbox day1msg day2msg day3msg

So, the message I opened most recently is ... farthest away? Is this intuitive to someone? Can I reverse the sort order here so that the messages I have most recently interacted with are most visible to me?

I want:

Inbox day3msg day2msg day1msg

I have looked for a config name and in the forums here, but am not seeing it. I am not sure what it would be called. Perhaps "tab order". But it is not message order and that is what _all_ of the posts are about.

Hello! After the reboot, crash, etc, the inbox index is not build, until I click the inbox. And until the index is not build, there is no incoming mail. But after there is a index, it will not downloading the mails in which i received while the index was down. I use pop3 for the google (I tried imap, but there will some issue with that (I think the two fact account), so i failed back to pop3) So after the restart the thunderbird, I losing all email until i click the inbox, force it to rebuild the index.

Is there any help for that?

thanx

To: Support personnel or Manu Andino Thank you for your help this morning on restoring the Thunderbird email server. It did crash again this afternoon 3/3/25 in the middle of writing/responding to an email. Any help you can give is appreciated. Thank you- Paul Behrmann

I’ve got a minor but annoying Quick Filter button issue which just cropped up today out of nowhere, and haven’t been able to find an exact match for all these symptoms in any other problem reports.

Toggling my Quick Filter button works as expected, picking up the individual active filter buttons. However, in some instances of launching TB its on/off status indicator always displays as active regardless of individual filter button status. Weirder still, in other cases it always displays as inactive. It’s an intermittent problem, which always persists in one way or the other.

Further details:

- Problem is also present in safe mode, with the single plugin I use (CardBook) disabled.

- General display settings are “Theme Simple” and “Variant Normal” (not “Dark”).

- There are no automatic filters configured in “Tools > Message Filters”.

- Individual filter buttons are all working properly, including correct status indicators.

- Running current TB version (128.7.0esr 64-bit) on Windows 10 with all OS patches up to date.

An example:

Image 1: “Show only unread messages” button is active, and the Quick Filter button also displays as such (both indicators are correct).

Image 2: All individual filter buttons are inactive, yet the Quick Filter button still indicates a filter is active.

I’m stumped, thanks in advance for any help!

For some reason, I am getting message that the Certificate for server is not valid (etc.). I can not get or send my emails as of this morning. Is there something I can do to resolve this issue?

My Macbook Pro has been crashing - sometimes Firefox, sometimes Thunderbird -sometimes multiple times/day. I've saved many of the crash reports in case they might help someone know how to fix this. An Apple tech person diagnosed my memory was broken, so I just got a new logic board and reinstalled all my data from my Time Machine backup. Then a message popped up that Thunderbird was damaged and should be put in the trash. Around the same time i replied to an email from someone at Thunderbird donor who was responding to a question i had about a small donation i tried to make - i explained i was having trouble with Thunderbird. At that time, i could see the Thunderbird icon in my task bar. When talking with someone from Apple support this evening who was helping me answer a couple of questions, including about a new "mail" icon that showed up in my task bar, I mentioned that i'd like to learn how to back up or archive my emails in Thunderbird. That's when i saw that the Thunderbird icon - had disappeared. The Apple support person and i searched all over my computer for the Thunderbird app, but couldn't find it. I'm really nervous. I have over 300,000 emails I've been wanting to learn how to archive - or something. I don't want to delete most of them. I hope someone can help me find everything. Thank you.
