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!

Hi, I have downloaded the latest Thunderbird and it is driving me mad because I KNOW there is a simple solution (I hope) When I used to open my emails they were all listed from oldest to newest and Thunderbird would automatically go to the bottom of the list where my latest (newest) emails were, NOT ANY MORE it goes to the older email in my in box, click date and YES the latest email rushes to the top of the list BUT I want it at the bottom HOW do I get the emails back the way I like them?

Long time user and supporter of Tbird here... While I really love and applaud the improvements to Thunderbird 115.x, I have noticed the Quick Filter seems to be noticeably slower than the 102.x version. Is there any work going on in this area? I use this function heavily in my day-to-day work and any speed improvements would be greatly appreciated. Many thanks for your time.

I need to protect several people who do not need to have their day FUBAR'ed by this corrupt version.

Heck, I need my installation to be rolled back to existing stable.

It's currently unusable.

The update to Thunderbird 115.0.1 broke the "Unified folders".

I have two eMail accounts: - the first on a custom server, I do not know its characteristics - the second is an Office365 institutional account

Only the account on the on the custom server is shown in the Unified Folders.

The second account is shown as a folder in the Unified Folders pane, at the same level as "Archives", "Junk" and "Deleted".

I have tested one solution reported to be working: https://support.mozilla.org/en-US/questions/1003446

It does not work in my case.

Any help?

Can I roll back from version 115.3.1 to the previous version? I don't not like this new version at all. Surely an email client should be what it says, a means to receive, send and organise emails. I don't need 'chats' calendars or any other gizmo's.

Please just give us an email client that is the best, like it used to be.

It appears that Thunderbird Supernova version 115.3.3 (Windows 11) has a bug or compatibility issue with large profile file and/or Storage Management - Intel Optane Memory.

Since I installed that new version, Thunderbird has been slow and stops running frequently.

I hate the way the new Thunderbird version looks, can't get normal number of emails at once, can't read any of them at the bottom of the page. Please give me my old version back. This was a horrid intrusion with no warning that it wasn't just a normal update

Migrated for old PC which showed all emails listed sorted by date in the Unified Inbox. New PC lists email accounts but only visible by individual email account. The unified inbox folder is blank. Version 115.2.2

In Thunderbird 115.3.1, when I click on the Hamburger menu (3 horizontal lines), there is a "Font Size" option, but it does not do anything. Clicking + or - or trying to type in new font size - nothing works. Why?

Thunderbird update 115.3.1 self installed now nothing works.

When I first opened program after update and tried to retrieve mail for one account (of5) got a window telling me password not accepted by pop server (at zoho.com) and asking if i wished to enter a new one. Said no and went to passwords in config to check if they had transferred properly. They had.

Tried again to download messages with same results (password not accepted)and clicked to enter new one. Instead window popped up for next account telling me password not accepted by server and did I want to enter a new one. Same results for every account in order without ever letting me access one. Rebooted - no change.

Downloaded copy from mozilla and re-installed thinking it may reconfigure what was wrong. No luck. Now when I try to retrieve messages I don't even get password not accepted only "done" in bottom left corner where it usually shows download happening.

I have used Thunderbird practically since it came out and have installed configured and transferred accounts across many computers and never had any problem like this!

Hi all,

Just upgraded to Thunderbird 115(from the last Non beta version).

I have multiple email accounts.

When I click to the inbox off one of my gmail accounts it does not display to the last message received. Thunderbird opens to a message about 1/4 up into my inbox.

I have a second gmail account and this behavior does not occur.

I'm sure its a easy fix, I just can't figure it out .

Since installing Supernova, I find a huge (multiple minute) delay whenever I open a folder to a new tab or window. There was zero delay on the prior version to open a folder, so it appears to be specific to Supernova. I'm surprised that no one else has mentioned it on the forums yet, so it seems it might just be something about my particular setup. Can anyone help me diagnose what I might be doing wrong?

Thanks!

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

I'm running Thunderbird 115.2.3 on Mac OS X Ventura 13.5.2. Since a few days ago, the Thunderbird interface will hang completely a few minutes after it launches. I can usually get in and read an email or two before this happens. No crash dialog appears, and I have to force quit the application.

A few things I've tried, unsuccessfully:

• Launching in safe mode has the same issue
• Deleting the global messages DB seems to make this issue go away for a while, but then it comes back again at a certain point (like after a day or so of use)

I was able to save a Mac OS X crash report, which is here https://gist.github.com/timstallmann/1bc7150c43054642e5e936782e247527 in case it provides any insight.

I hope there's a solution to this! I have been a loyal thunderbird user for decades and have never had a problem like this.

Since TB 115, I have issues with the "invite" functionality of Lightning, as follows.

It generates errors as follows:

• "invite" does not work. I can add emails to be invited to an event, but the invite is then not sent at least with the option "notify" + "send individual mail" (other alternatives such as open visible list of destinatories are not feasible due to privacy)

• when opening an "event" from the calendar, it displays in a full-screen format (see screenshot_2) that lists all invited attendees

• The "invite attendees" window works but has a strange pink block on top right (see screenshot_3)

• the page where the format of sending ("notify", "send individual mails") is not accessible any more

Currently the calendar as such works fine. But the "invite" function is critical for the use I am giving as transnational NGO to invite to meetings etc. All worked fine with previous TB versions.

System config: WIN10 prof, all updates installed, fully licensed, AMD Ryzen 9 5900X etc. (mid-end system built in 2022).

Thanks for looking into a solution.

Hi, I use new version 115.1.0. When creating calendar event and adding attendees, they don't get the invite and I don't see the message that sent in sent items folder. Please assist

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
