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!

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!

In Thunderbird 115 (Supernova) is there a way to configure the Message list view so that it has grid lines, or "zebra striping"? I find it easier visually to look at.

Thanks!

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 .

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

In Supernova (v115) on Windows 11, when I view a message by double-clicking it to open it in a new window, I can set the Mail Toolbar to visible, then right click on it and select Customize. In previous versions I would put large icon/text button up there for Reply, Reply All, Forward, Print, and Delete. Those buttons don't appear to be available in Supernova for this toolbar.

Some of them appear to be in a fixed area as buttons with text beside the icon, and this area does not appear to have any customization available. For example, I don't use the Junk and Archive buttons, so if this "button area" must remain visible in this position, I'd like to be able to customize which of these buttons are visible.

My real preference would be to not have these buttons appear where they are now (to the right of the FROM: info), but instead to be able to have them in the Mail Toolbar at the top of the window as I could in the past. See attached screenshot for clarification of the Mail Toolbar->Customize window that doesn't currently allow for Reply, Reply All, Forward, Print and Delete to be added to the top Mail Toolbar.

If you want your 'Message List' to use alternative colour stripes often refered to as zebra style then I have put together some code and instructions on how to create the effect.

Obviously you may need to modify the actual colours used. The following works on a Light theme. The striping is white and pale grey. On hover the text is black on a pale blue background. On select the text is white on a light blue background, but strong enough to show white text clearly.

As of version 115.0 for 64bit, I am unable to send emails to Outlook.com. An error occurs saying:

Send Message Error Sending of the message failed. The message could not be sent because the connection to the Outgoing server (SMTP) smtp.office365.com timed out. Try again.

There are no issues sending emails to Outlook.com using a different mail client.

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?

I just want all of my folders and sub-folders to have the same display columns! With 115, you can change any folder or sub-folder to any column organization you want, but I want them all the same. 115 changed my display columns - why couldn't you leave them alone, Thunderbird??? I can go in and change them back manually, so why were they changed at all??? I don't want to have to change each folder and its child folders individually - I have a few dozen folders, most with dozens of sub-folders. I tried the "Apply columns to ..." and selected Local Folders to change them all - none of them changed! I saw the video from Castellani claiming that TB tried to make sure that upgrading wouldn't take hours to reconfigure back to a usable state, but that's obviously not true if you have more than the one or two folders shown in the video.

Mozilla/Thunderbird -- Is it so hard to leave things as they are and just TELL us there are new features available, if we want them, instead of DESTROYING our well-used setups and forcing us to come here in hopes that someone can save us from hours of tedium just to be productive again?

Thanks to anyone who can save those of us who just want our setups back the way they were!

Manjaro 23.0.0 Thunderbird 115.0.1

Before the update to Supernova, Thunderbird light theme used the system color for the UI elements highlight. In my case, green. Now it is blue everywhere, which irritates my eyes. I attached before and after images, so you have an idea. Can I get back the green?

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

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?

I'm so tired of, frustrated with, and annoyed by the reduced and very cramped text viewing area display in the new Thunderbird version as of July 223!! This is because the minimum line item display of emails is now three times the previous minimum of only 3 email lines!! And there appears to be no way to reduce that minimum!!

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!

Thunderbird just upgraded to "Supernova". I hate it. I'm trying to adjust as many things as I can to make it look normal, but I'm stuck on the font. How can I change the display font used so that my folders and email information (NOT the font used in email messages themselves) is different from the default?

Also, is there any way to change the density or size of just one pane? My email list is too cramped, but if I try to change the size or the density, it changes the the all the panes, and so then my folder list looks way to spread out.

Unified Folders in Thunderbird 115 for mac no longer works. Useless! Computer Tech specialist here and have been using Thunderbird for ages. With this latest version, the inbox, sent, etc etc etc no longer display as unified. The Unified Folders category when ON shows as its own item in the left column with a single empty inbox! Scrolling up and down to each account for each subfolder is a waste of time!!! Hope you fix this ASAP!!!!! Unified folders works fine in 10.12.13 but I cannot got back to that due to your system.

Hi This morning I was blessed with update 115 for Thunderbird. Not impressed. I have a couple of issues I hope you can help with.

1. The box that lists incoming messages is way too long, taking up over half the screen. I moved it up as small as it will let me. 2. The second question is the box in between inbox and the message (middle pane) is also way too large. Ideally, I would only like it to display the top line. Remove the to and subject line The attached screen shot hopefully will help you see the issue. Please note that on the bottom of the shot is probably 3/4 way down my screen with very little room to read the message. Perhaps 3 or 4 lines at best.

I want the unread messages in the list of messages pane to be "orange". I had the following in userChrome.css which worked prior to TB 115:

/* Messagepane text */ treechildren::-moz-tree-cell-text(new) {

      color: #34ebdc !important;
      font-weight: normal;

} treechildren::-moz-tree-cell-text(unread) {

      color: #34c6eb !important;
      font-weight: normal !important;

}

When I upgraded to TB 115 this no longer has any effect. How do I do this in TB 115+?

Thanks. mike

I see that Thunderbird has the idea of "Unified Folders" -- which I interpret as their version of "Smart Folders". As far as I can tell, this is an all-or-nothing option. What I would like the ability to do is to define my own "Smart Folders" to link material I need in that context. I can't seem to find any information on whether this is possible, or it's not obvious (to me).

I am running Thunderbird 115 Supernova.

Thanks.
