I have 2 hotmail accounts - one gets mail as normal the other stopped on 28 April. Checked and settings are same for both except actual email address name. Till 28 April both worked normally. Haven't tried either starting another account for the problem name or deleting existing as don't want to lose anything. Haven't updated to latest version for same reason. How to fix please?? Cheers and thanks

Hello all,

Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.

Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk

The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.

The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.

The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.

Messages in all of the other folders are visible.

At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).

I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).

I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.

Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.

I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.

Thanks in advance.

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

Hello I seem to have lost the ability to choose whether my bookmarks toolbar displays icons and text or icons only. At present I have icons plus 4 letters of text fading out. I want to return to icons only. How do I do this? Regards

I've asked this before to no response. I JUST did a new search and found a users solution that I just tried to no avail. Which was to add the Provider for Google Calendar Extension, then unsubscribe and resubscribe to my Calendars! The old W7 version of the Calendar had the ability to have a Reminder EMAILED to oneself! That option with the new W11 version has disappeared! Can someone please ask the Coders to re include this option! THANK YOU! I 'LIVE" by this option! My Iphone 3rd party Calendar thankfully still has this option! But I would LOVE to have this back on my W11 Laptop in the Thunderbird Calendar!

I get an app popping up many times per day

It wants me to load Firefox

already have and use Firefox

How can I stop this very annoying request to load firefox?

Is there a bug in the code for v152? I need to connect to a ms office 365 email account with requires OAuth

The create new account process does not work, because it forces you to go through the whole (manual) process which then fails because you cannot select the Oauth option from Authentication method dropdown box - because its not there !.

This URL with the process to add OAuth: https://www.bing.com/search?pglt=419&q=setting+OAuth+in+thunderbird&cvid=22ed20c67b3843d58ddbc136bed2f174&gs_lcrp=EgRlZGdlKgYIABBFGDkyBggAEEUYOTIGCAEQABhAMgYIAhAAGEAyBggDEAAYQNIBCTExMjgyajBqN6gCCLACAQ&FORM=ANNTA1&PC=ASTS

fails at Step 2 because it does not let you complete to then go to Step 3 - because the account is never created !

How do I fix this ? thanks

I have had quite a bit of difficulty getting Firefox VPN working. I just now got it working because of an article I found on Gizmodo.

Setting browser.ipprotection.enabled to true fixed the problem of the VPN button not showing up immediately.

I am just wondering if there is a way this could have been done through normal Firefox settings, whether this could be added to the Firefox help documents on this subject (I could not find them, but it already may be there.), and whether this could have any other harmful security effects since I got this from a non-Mozilla source.

Thank You!

Something seems to have changed recently with the PDF rendering in Thunderbird. I received an email with a PDF file attached. When I view it on the screen it looks fine, but when printing it out from within Thunderbird part of the top of the first page missing; it looks like part of the image is behind a white rectangle.

When I save the file and print it using Acrobat Reader it renders fine.

I don't know what to make of this behavior, but it does seem to be new and there is a difference between how the file is printed from Thunderbird as opposed to printing using Adobe Reader.

Thunderbird 152.0.1 on Windows 11 PC.

PRELUDE: I have Thunderbird (TB) Version 152.0.1 (64-bit)

I have 45+ email addresses, some at various different domains, 8 (was 10 yesterday) Email accounts with Shaw that was taken over by Rogers. It's been a nightmare. I now have TB working almost as it should, and am use to but, one account has issue.

I tried to format this so it's easy to follow, but more formatting is not available so please see the pictures attached. Pics are self explanatory, but in case, pic 1 shows 3 accounts. The address with issues is the middle address (fake-two (faketwo@there.xy). The other 2, fake-one and fake-three have all their folders.

ANSWERS to possible questions: I used a outside mail to send/receive to/from fake-two. It receives and sends Email.

I just installed the latest version of Firefox. Now the reload button has gone from the toolbar.

When I click on customize toolbar it is not there either so I can't add it back.

Can someone please tell me how to get his back?

I've tried resetting and that didn't make a difference.

Around July 2nd I opened FireFox to find that the text on whatever screen I was on is spaced in an ineligible form. It seems to be the correct spelling, just jumbled together. I've tried adjusting the fonts, browser acceleration, to no avail. It's becoming difficult to read, and it has only been affecting the desktop browser. It works just fine on my Mac and phone, but not my windows computer. It is the only application that does this. I've updated my drivers and all.
