As per the picture, when sending an email, the menubar 'partly' appears. Yes, if you press <Alt>, it shows normally, but when it's supposed to be hidden, it's still there...

Thanks.

Thunderbird 153 in Linux Mint 22.1 XFCE.

I use Waterfox installed via flatpak as my default browser. Unfortunately Thunderbird's Oauth2 verification pages don't open correctly in that browser, due to some of the browser add-ons I have installed in Waterfox.

I also have Firefox and Chromium installed. I want Thunderbird to always ask which browser to use before it opens a link. I followed instructions I found in multiple places on the internet:

• Open config editor
• Set network.protocol-handler.warn-external.http and network.protocol-handler.warn-external.https to true
• Restart Thunderbird
• Click a https (or http) link in an email: Waterfox opens
• Settings-General-Files & Attachments: There is now an Action dropdown for https (or http) with options 'Always ask', 'Use Web Browser (default)', 'Use other...' and 'Delete Action'. The current selection is 'Use Web Browser (default).
• Change Action to 'Always ask'
• Restart Thunderbird
• Click a https (or http) link in an email: Waterfox opens again, even though 'Always ask' is still the selected action.
• Restart Thunderbird.
• Settings-General-Files&Attachments: The https (or http) action has now changed back to 'Use Web Browser (default)'

How do I get Thunderbird 153 to ask which browser to open for a web link?

I just added two new email accounts to my Thunderbird installation, which has been working with three accounts flawlessly for years. All my accounts are POP/SMTP.

Both the new emails are Google Workspace accounts for an in-home business. One uses (my) name@(domain) as the account name, the other uses info@(domain). The account using my name works fine, sending and receiving. But the info@ account does not display a Sent folder, and will not send messages. It looks as if it does, but they never show up. I checked the Account Settings and the two new ones are set up identically, and just like the other accounts that have been working just fine. Any ideas? Many thanks in advance.

I added two new email accounts to my Thunderbird installation (140.12.1esr (64-bit) under Windows 10), and am able to receive and send mail just fine. But the T-bird Search utility doesn't work for those accounts. I can do a Search for an email address, subject, etc. that's showing on my screen for those accounts, but the Search utility comes up empty. Search does work for three other accounts, however. Any ideas?

When I trash an email, I can no longer view the attachments in the trash file, though the email itself remains until the setting for trash deletion has been reached. Since I have a gmail email address I can still view the attachments via the website for gmail. Does the attachment disappear on Thunderbird because of a setting - or is this a "feature" of Thunderbird?

Linux Mint 22.3, Cinnamon Thunderbird 153.0 esr

clicking on 'get messages' produces no response. zero. Nothing happens. two email accounts are affected.

Consistently Reproducible.

Each time I open TBird, I get a message at the bottom left of the screen telling me that TBird has deleted X number of messages. I do not want TBird to ever delete any messages. How do I turn this automatic delete function off?

Since I updated Thunderbird to 153.0 on Thursday, I've noticed that every time I start Tbird, I get several notifications about authentication errors for the servers to which its trying to fetch mail. The list varies each time, but frequent offenders are Gmail, Comcast, and Yahoo, and occasionally Apple and Microsoft (outlook.office365.com server).

I did not see this issue prior to the update. Sure, once in a great while (< 1x/month), a single server would throw such an error, but now, it's every time I start Tbird.

All the accounts are accessed via IMAP, and those that support or require OAuth2 are so configured.

If I go to the mailbox a little while later, I don't get any errors--this seems to be limited to startup.

I check 15 mailboxes, though many get very little email.

A search from Bugzilla's home page shows three similar reports, none newer that 3.5 years ago. (I can't delve deeper, as my credentials apparently expired and the signup confirmation email has not arrived yet).

Is anyone else experiencing this? Is there a log of such events (or a way to create one)? ...thanks!

What I want to do is to is export just the headers of emails on IMAP folders with an Excel VBA macro so that I can write filters to import into Thunderbird for deletion of old new letters and things of that nature, keeping only the important emails.

Knowing the message filter file format would also be nice considering that I can then just mass edit the filters without needing to recreate them each pass.

My daughter added email to my phone. Now I can not send any emails on my computer or phone! I still get my emails on Thunderbird but can't send any and have no idea what my password is or where it might be stored on my computer. It isn't saved on my Firefox. I do make annual contributions to Mozilla.Len@sawisch.com

Essentially, I’m wondering if thunderbird can be used to store old emails on a hard drive. I am wondering because I would like to be able to access them without the ability to use the internet because it would be on an old computer with no WiFi card or Ethernet capabilities. I would like to be able to store all of these emails with as little connected to the internet as possible.

Recently it's a daily occurrence that I must enter the password for my SMTP server. I always check "Use Password Manager to remember this password" but it doesn't help. The next day I'll have to go through this again.

I power on my machine multiple times each day, and I use Thunderbird each time. It doesn't happen each time. It seems to happen only the first time I use Thunderbird each day. This is new behavior. Before it would happen now and then, now it's daily.

I don't have a Primary Password. No need for it.

If you need to see the message I can send it to you, but I'm not attaching it right now because it shows my email address and the smtp destination. Maybe I'm being too careful.

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

my thunderbird freezes at the point of checking mails. when i try to update it, it opens a new application completely and doesn't update my present one. i also can't find the location of the app or the data. pls help!!!

I'm trying to dump Windows and move to Linux and I need to migrate my existing mail. The Export tool says it exports accounts, messages, address books, and settings. I've done this and have my Linux Mint Thunderbird installation up and running. The problem is the only "messages" it exports is the Inbox. Not "Sent" or any of the other 25 folders I've created to organize my mail. Is there ANY tool available that will export everything and then import it into a new installation?

I for sure don't want to have to dual boot just to do email. If I can't accomplish a complete cut-over, I'll abandon Linux and stick with Windows (ugh!).

I'm actually using Mint right now and I would need to go back to Windows to get that version number. Suffice it to say, as of yesterday, it was up to date with the latest Windows version.

Steps to reproduce:

Open Thunderbird. Account settings: Check "Check for new messages every 10 minutes". Keep Thunderbird running forever.

Actual results:

Sometimes Thunderbird stops checking messages for no reason. No checks are done for many days.

Expected results:

It should always check messages every 10 minutes, keep checking forever.

I was asked to post this here in https://bugzilla.mozilla.org/show_bug.cgi?id=2057745

I successfully linked / synced the thunderbird calendar with the iCloud calendar. Calendar entries manually entered in iCloud or iPhone calendar are successfully synced and are visible in the thunderbird mail. The other way round, syncing the existing entries in the Thunderbird calendar does not work. They do not appear in the iCloud or iPhone calendar. Searching the internet, the specific Thunderbird or Apple help-sites did not provide an obvious solution for this problem. I went through all (or nearly all) recommendations given by Apple, no success to sync from Thunderbird to iCloud.

Any suggestion what to modify or adjust
