Hi. I have removed the eng-US dictionary via settings, which informs me my only dictionaries are UK English and Welsh as I live in Wales and use the eng-UK as default. However, the email spell check keeps defaulting to US. How do I stop this from happening as it is very annoying and the dictionary needs to be reset to UK every use.

I have downloaded an update from Thunderbird about a week ago, and since then I have been unable to send emails. when trying, a box appears that tells me i MUST ENABLE AUTHENTICATION TO USE THE EMAIL SERVER? My provider ,SLINGSHOT.CO.NZ cant seem to help at this stage. I did find while searching Thunderbird that the recent down load w as not completed,why, I dont know. But I desperately need Thunderbird to get my outward mail operating. Thank you, J. Tresidder c/o-email. --johnnyripper@slingshot.co.nz.

I can't move messages to my local folders: thunderbird only offers me the trash. These folders were created in ORANGE messaging but are clearly visible in thunderbird

I have not changed my email accounts or my Google & Microsoft usernames or passwords. A few days ago when I started Thunderbird, two Google pop-ups arrive reading "Mozilla Thunderbird Email wants to access your Google Account" demanding that I deny or allow it. Why might this be happening and how do I stop it? This does not occur with other email apps such as Outlook for Windows.

NYU has used gmail combined with shibboleth MFA for over a decade. When there's a password change, TB opens a window using it's own browser (n.b.: this is different than the browser used when clicking on a link) and you go from there. This morning I did my yearly password change and now, after the initial accounts.goole window, when I get redirected to the shibboleth window, I get a 403 error. I also get a warning about invalid certificate. I tried pressing the "Get Certificate" button, but nothing happens.

A few thing to note: - I run TB (128.5.2) on a Mac Sequoia - no issues when logging into NYU using Firefox or Chrome or Safari. - I cleared the TB cache and cookies. - I created a new TB profile and tried starting from scratch. - I restarted TB with add-ons disabled

Nothing seems to solve the problem. Unfortunately NYU's IT can provide only limited help with 3rd party apps like TB.

I really depend on using TB, been using since the first release and have add-ons that I use on a regular basis.

Thanks,

I just upgraded my desktop pc from Windows 10 to 11, and before the upgrade I used the Tools Export function to export my complete Thunderbird profile, so I could import it after the upgrade. Unfortunately the export file cannot be read on my upgraded pc using the Import function - Thunderbird gives me error messages every time, that suggest the exported folder might be corrupted or invalid.

My IMAP emails are fine, as I have set those accounts up from scratch and the folders have now populated with all the emails - the problem is all my filed emails, dating back many years, which were all stored manually in a filing system under Local Folders.

I tried manually copying across the individual files from the extracted back-up folder into my live Thunderbird profile and then reopened Thunderbird...which worked to some extent...as in, all the folders are there, but no emails are showing! It shows no messages under each folder, even though if you look under the Profile you can see that the email files exist.

I tried various ways to bring them in, including zipping one of the folders and trying to import from the zip file (which also brought in a folder but no emails) but even though the email files are clearly there under my profile, Thunderbird shows 0 messages in all my Local Folders. It's as though it is unaware the files exist, so I suspect it needs them to be formally imported somehow?

I would hate to lose the emails, as they document important information and purchases etc over many years, along with archived emails for my charity work, social events, etc. As I said, I can see the files are there but simply copying the files to my profile has only worked to the extent the filing 'structure' is visible, Thunderbird doesn't display any of the emails.

I have included two images...one of my Thunderbird Local Folders as they currently look, and the other showing the backed up files existing in my Profile, which I hope are helpful.

Can anyone help please? I am running a desktop PC on Windows 11. Thanks, David.

Hi there,

I've used Thunderbird for many years with a Gmail account. I access the account using both IMAP(993 SSL/TLS) and POP3 (995 SSL/TLS) via two different account definitions within TB.

I use POP3 to basically download and create an archive from the emails. That would work by POP3 pulling down emails to its own inbox and then a few Message filtering rules on that mailbox moving things into Local Folders (so the POP inbox would remain empty). Email would also be left on google servers. Email on the servers would be left in Unread state.

The IMAP account setup was maing for mobile access etc. This was basically separate to the POP3 tasks.

This has been working since 2011.

I recently notice though that emails weren't downloading via POP3. I've always had logging turned on, and that shows it last processed new email for the POP3 download back in August 2024.

I can't figure out whats broken. If I do a manual email-fetch, everything seems to run and it just seems to think there's no new email to pull down. But thats not true.

I've looked at the gmail settings and nothing looks different.

Is there some way I can debug further within TB to see whats happening ? The existing log just shows nothing at all.

I can pull a wireshark log of the POP3 comms if I switched away from SSL, but I'm not sure gmail supports that

Immediately after updating to version 128.x a few weeks ago, the Calendar app hangs every time I save an event or dismiss a reminder. It shows the spinning circle and Windows says "not responding" for 60-90 seconds at least every time. It was fine before this update but this issue started immediately after updating to 128.x - has anyone else seen this?

A few days ago my wife clicked to open an email and the whole Thunderbird page changed so that it is now almost un-usable. I tried using the program that allows you to recover to a previous day with no luck. In frustration I saved the email file from profiles, uninstalled Thunderbird, rebooted then downloaded a new copy of the software and installed it, no luck, it opened with all my emails in the same almost un-usable configuration I can still receive email from a webmail program but it is slow and frustrating. Any help would be greatly appreciated. Bruce

Thunderbird keeps crashing on startup with msg: Crashed Thread: 4 Breakpad ExceptionHandler

Exception Type: EXC_CRASH (SIGKILL (Code Signature Invalid)) Exception Codes: 0x0000000000000001, 0x0000000000000000

Termination Reason: Namespace CODESIGNING, Code 2 Invalid Page

So, it looks like the the app "signature" is corrupted. How do I remove signature and and correct for valid signature. Thanks.

I'm having the exact same problem as described in this question: https://support.mozilla.org/en-US/questions/1440106

I had a university email account in Thunderbird, and then I attempted to delete the email from Thunderbird as it had been deactivated. I deleted its entries from saved passwords / the calendar. However, I'm still getting a googleapis.com login prompt every time I open Thunderbird, although I can find no references for it anywhere.

The answer to the linked question recommends checking the address book for a caldav link to the old account, but I don't see anything like that so either I'm looking in the wrong place or that's not my problem.

I appreciate the help, I love Thunderbird but this is getting really annoying.

After DECADES of Mozilla, I am DONE. I have donated, I have advocated, but Mozilla has too many problems, and I am now unable to even run the program due to the "Couldn't Load XPCOM" error, which is apparently so common there are threads about it. Before that it was impossibly slow delete times, which I managed to fix by messing with windows security. I feel the user should not have to deal with this, especially a donating user. Mozilla is, by far the best mail program... but now I can't even run it and I don't really like having to use "work arounds" on a program I am paying for. Oh, and I HAVE attempted deleting the folder, turn off security, reinstall option to no avail. I will miss this program for sure, but I think it's days are ultimately numbered.

All the emails (about 100) suddenly disappeared from one of my folders. They are there when I search, but the program won't open them. In the explorer, in the profile folder, both the 'cur' and 'tmp' folders are empty. I didn't delete them, nor were they moved to another folder. I tried the 'repair folder' method, but it didn't help. How can I somehow bring them back?

Is there is a way to remove the icon for the set "columns to display" since that can be accessed by context menu. And is there a way to resize just that row? Not the emails but just the from,size,attachments...etc row?

Such an annoying problem with current version 128.5.2esr. On one notebook with Windows 11 Hone I install the latest version (no Thunderbird previously installed), works fine.

One another notebook with Windows 11 Home existing Thunderbird freezes. After startup it just hangs, using so much CPU, that the battery is half drained after 30 minutes. Then reinstalling does not help. The same issue persists.

I read that uninstall does not remove the profiles and that cause the issues. Is that possible. Feature request. Also it would be fine to have the option to remove the profile on uninstall, so the non-tech savy user has also a chance of using this client.

When I make changes in the settingsscreen the changes are NOT be saved. Since the latest update 128.4.3esr I get everytime a donate screen. But I donated serveral times last month. How get I lost off it!!!
