When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

Hallo, Ik gebruik 2 verschillende gmail-adressen in Thunderbird. Met het ene adres heb ik geen probleem, met het andere krijg ik steeds de melding "Authentificatiefout tijdens het verbinden met server imap.gmail.com". De serverinstellingen in de accountinstellingen in beide adressen zijn identiek. Hoe los ik dit op? Bedankt voor uw reactie.

Most of my work life is in email. Over 25 years (starting with Mulberry) I have built up a custom IMAP folder hierarchy that makes work manageable, but Thunderbird 115 has broken this, now displaying nested subfolders at the top level sorted alphabetically. See the images for before and after. For example, there are now three "Administrative" folders that were formerly classified under superordinate folders for my roles as lab leader, graduate program chair, and departmental faculty member. Persons who used to be in Colleagues or Students subfolders are now at top level. Inexplicably, a few folders retained their hierarchy but most are flattened out. Now I need to scroll through hundreds of folders (have not counted recently but in the late 2000's I had over 500.)

I was able to revert to 102.14 using backups, but will be stuck with this version for the rest of my career unless Thunderbird fixes these problems. Thunderbird is so important to me that I make an automated monthly donation to the project, but will have to cancel if this is not fixed.

If anyone has found a work around please LMK. And Thunderbird team, please acknowledge and LMK whether this will be addressed or are IMAP users left behind?

Thanks, Dan Suthers

I am a longtime Thunderbird user, currently running 115.6.0 (32-bit). Very recently Windows Defender is detecting malware it identifies as Trojan:HTML/Phish!pz. Defender is unable to quarantine or eliminate the threat.

The specific file is appearing in Volume Shadow Copy data when I am running backup: file: \Device\HarddiskVolumeShadowCopy55\Users\fhanz\AppData\Local\Thunderbird\Profiles\sootdszw.default-release\cache2\entries\342F92977A0BA0715CB8880A9289BC8F8827262C

I've attempted several times to remove the offending file(s), but the problem returns.

What is the best method to determine the source of this malware and effectively eliminate it returning?

If it matters, I use Chrome as my default browser.

I posted the following question 1 month ago. Can anyone help me with this, it's driving me crazy! Please respond.


- Open TB - Open Inbox to see all emails - Open an email, read it, delete it - Scroll down, reading email Subjects until I find another email I want to open (this may be 30-40 lines or more) - Open another email, read it, delete it

The cursor/highlight then jumps back up to the previously highlighted email (next to the first email I deleted). Now I don't know where I am, I don't know what email Subjects I have already looked at, I don't know where the next unlooked-at email is. In order to get back to where I was before I deleted the second email, I have to scroll down through many emails I have already scrolled through.

How do I stop TB from doing this? I want the cursor/highlight to stay right where it was before I delete any email, I do not want it jumping to some previous location.

I have searched for instructions to remove an email account from Thunderbird. The only problem is that most of the solutions are from older versions of Thunderbird and although I've tried to find the resources in my version,115.3.1, the screen I have is totally different from the older screens. All of the instructions I have read tell me to look for Account Setting> Account Actions> Delete Account. I can find Account Actions, but there is no Delete Account under Account Actions. Also the traditional top menubar (File,Edit, View,etc) is nowhere to be found.

I need to find out how to delete an email account for this version of Thunderbird. I've included how my screen looks now. Any help would be appreciated

Suddenly, I can't send email from my Thunderbird (115.6.1 (64 Bit)) Windows app. Spectrum is my email provider. I can receive email just fine. However, when I respond to an email and when I send a newly created email or replying to a receive email, I get the following error message - " Sending of the message failed. An error occurred while sending mail. The mail server responded: <[edited] @tx.rr.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your account settings and try again."

I've been using Spectrum and Thunderbird for many-many years. This problem is going to cost me big-time if not resolved soon. I love THUNDERBIRD!
