It seems that US English is the default dictionary on Thunderbird. I'd like to uninstall it so that the Canadian English dictionary is the default one.

How do I rid myself of the US dictionary?

Thank you in advance for any assistance you may render.

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

I am on 140.7.1esr (64-bit). My sub-folders under Inbox is not sorted alphabetically. I do not see any option to re-sort at the pop-up menu after I right-click at the account name. Does this mean the version I am on does not have this feature?

Win 11, v.153.0 Firefox (default), v.153.0 T'bird.

Lately, when there's a link in an email and I click on the link, it takes me to a Firefox browser that's not my normal one - this new one doesn't have my settings, saved passwords, or home screen default, etc.

What happened and how can I fix it? Or must I wait for another update? (It just now updated to 153.0 and the problem still exists)

It is quite annoying.

Thanks.

Trying to send 3 different emails. Hit send and get: 1) Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. 2) Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. 3) Your draft message was not copied to your drafts folder (Drafts) due to network or file access errors. How can I get these problems fixed?

Thunderbird indicates that I'm not using a primary password and when I ask to see the password for my gmail account it asks for a PIN. I have no record of a PIN for Thunderbird. I'm instructed to go to setting>accounts to change the PIN. but cannot find it: settings>account settings lead me nowhere.

I've used Thunderbird for years. computer crashed and I'm trying to install Thunderbird on my new PC. Thunderbird cannot find account. I've checked with my provider several times and all settings are correct. Any ideas? I've also downloaded installed and uninstalled 5 times today with the same result.

I have a consistent issue where moving a folder with its emails to a subfolder makes it so I can't see the contents of the emails. It also causes the same thing on all other folders.

Repairing folders doesn't seem to fix it. Closing then restarting TBird fixes it. Is there some other way to do this?

Thunderbird keeps asking for my passwords for my email account and that of my husband. Despite being on the phone for 90 minutes with Virgin Media and giving them remote control of my computer, the problem is still there, even though it did work for 5 minutes whilst the Virgin operative was on my screen. He signed off and when I looked at my Thunderbird accounts soon after, the problem was back again. All the settings and passwords are definitely correct, so why does it keep asking for passwords every few seconds? Retry, enter new password, cancel. I even made a £10 donation to Thunderbird yesterday, in hope. I am so frustrated because my husband has Parkinson's and I need our emails to work. What on earth is causing this problem or has Thunderbird itself crashed out of existence ?????????????????

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

For the second time today, I lost the entire body of a rather detailed email I was composing for two different glitches. When I started to reconstruct the first I was hitting cntl-S frequently. I relaxed a little for the second and was about to save, but I got a message about the attachment from my drive that I was forwarding, and the entire body was again lost.

From the posts I've read, it appears I'm not alone. Unclear what triggers the saving of a draft, but is there a way to increase the frequency? Between the two I lost today, I wasted over an hour and lost some of the original thinking.

I searched the setting help, but didn't find anything.

Thanks! Bob

I find now that Thunderbird requires Earthlink's password each time an email is sent. Earlier it required it once a day. I am on Windows 11 using Earthlink.net for provider.

Hello, I created a first account for Mailo email (no problem).

I created a second account for Orange email, but when I get to the contact and calendar search stage, it just keeps spinning (see attached Orange 1). Clicking "ignore" opens a window (see Orange 2). If I click "continue," the account is created and seems to work, but...? Indeed, both Mailo and Orange use IMAP port 993. For the past few days, I've been trying to get this account set up properly, but I haven't found anything specific online.

I've repeated the process several times, even uninstalling and reinstalling Thunderbird, but nothing has changed. I'm starting to get confused. I even think I deleted both accounts and started the setup process with the Orange one, but it's doing the same thing even though there's no other account. I should mention that the POP/IMAP option is enabled in Orange email.

Problem Initiating New Calendar in Thunderbird 140.12.1esr. Currently sharing calendar information between two accounts, both from Google calendar. Syncing between Google and Thunderbird has been working smoothly. Recently added KC Chiefs schedule to Google calendar. The KC Chiefs schedule displays correctly in Google, but does not display in Thunderbird. Attempts to add the Chiefs schedule directly to Thunderbird using the indicated (Google) 'Integrated Calendar' links fails. How do I obtain an .ics file to add this to my Thunderbird. Additional thoughts, my system is Linux Mint, and I am currently operating behind a VPN. Thanks,

"connection to server pop.mail.yahoo.com timed out" I have been getting this message in the activity manager for about a week now. When I click get messages, it says down loading message 1 of 1, but nothing happens.

Whenever I start Thunderbird, I get multiple (2 or 3) connection reset errors for random CalDAV calendars. When I sync the calendars, there are no errors reported and the exclamation mark on the effected calendars goes away and 153 and they are refreshed.

How can I solve this?

Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.
