Thunderbird 115 forcefully migrated my older profile and did NOT leave a way to go back?

That is NOT the way to do this.

You need create a NEW profile for the NEW version and LEAVE THE OLD PROFILE ALONE!

You must also have an alert, and explain the process, transparently giving the owner of decades of e-mail the opportunity to safely upgrade AND have the opportunity migrate back if they so desire.

How DARE Mozilla treat users and their data so casually.

This is NOT the way to do this.

Currently FURIOUS that this trusted tool has left me NO way to downgrade back to 112 except to rebuild my profile (and all the various e-mail accounts) from fucking scratch.

I like Thunderbird and I feel like I know it fairly well. Not well enough to have turned automatic updates off.

It has 4 email accounts on it - 3 hotmail accounts and one standard email account from a domain I own. On 9/15/23, I started Thunderbird and the hotmail accounts were asking for permission for Thunderbird to access them. I knew this was update related because Thunderbird opened a browser window announcing the update with a what's new thing.

Fine. Things change. But here's what happened... There was an unwanted, problematic change in my Unified Folder section where there are normally only Inboxes of the 4 accounts. The hotmail inboxes were OK but the non-hotmail email had all of its SUBFOLDERS now under the Inbox inside the Unified Folders section. With this change, ALL THE EMAIL (NEW AND STORED) are now part of the Unified Folder section. These hundreds+ emails are now displayed when I choose the Inbox at the top of Unified Folders.

Did not know what to do to try to fix this. Ended up uninstalling Thunderbird, deleting the folders inside of Local and Roaming directories in AppData and reinstalling an old version (102.15.2.2). I also turned off auto updates.

I installed only one email account - the one that was messed up and it looked "normal". Fine again. Tried to do the update to 115 and the Unified Folder section did the same thing with this account by putting all the IMAP folders under it at the top instead of having it separated lower in the main Folders list. So I uninstalled, deleted and reinstalled version 102, putting all 4 accounts back.

Attaching a screenshot of how I like it to look and a screenshot of what it looked like that I cannot tolerate. Unified inbox with ONLY THE INBOXES (with no subfolders) at the top and the other folders of those accounts at the bottom. If there is an easy way to change the Unified Inbox on the new release, I would like to know it in order to try so I can keep the updates current.

Thanks, Steve

Hello,

The new UI has this massive customizable toolbar at the top of the screen, it wastes a lot of space and doesn't look good compared to the old UI, you can fully customize it even leaving it blank but that does not remove it entirely and it looks off with just a blank nothing up there, where is the option to completely remove this new toolbar?

Regards,

Thunderbird 115.0 (though also happened on 102), M2 macbook pro; OS up to date.

On AC & battery, thunderbird uses up huge amounts of power sporadically in its background activity, taking up ~50-80% of processor power & hundreds of gb virtual memory (see activity monitor screenshot attached). Computer gets pretty hot to touch with thunderbird on, which I don't see with other apps. Troubleshooting info below.

This has been happening for several months now, since I switched to thunderbird & was hoping it would resolve at 115. I can't find any correlation with other usage patterns of the computer (ie I dont think it's correlated with idle usage, but not willing to stage reputation on that).

Thanks so much for any help!

Hi.

Thunderbird now crashes almost immediately on startup, even in safe mode.

My latest crash report, which has been submitted, is bp-3abf51c7-3373-408a-acd9-d87220230810

I'm running Mac OS Ventura 13.5. Re-installing Thunderbird didn't help, nor did a machine reboot.

Thanks in advance,

Kukisvoomchor

I don't like my new layout - I presume from update. I can't move the line below messages up like I used to so I can't read messages below it. Everything looks too big. How can I get back to the plain old view. I have tried changing views

Good morning,

My Thunderbird was just upgraded to the latest version (115). After opening it the first time, my inbox folder no longer showed the subfolders for each account. I then dragged a single inbox folder to the inbox, but instead of moving or linking the folder, it wiped everything that was in it. Nothing went to trash, it is just gone. Is there somewhere else I might be able to find these emails? It is an outlook account, and they don't seem to be on that server either. Thank you for any help.

~ Mike

Hi,

My reading pane on v115 will only adjust downwards but I would like to adjust it upwards as was possible in previous versions.

Just to confirm what I mean, it will only go down, so making the reading pane smaller (or disapppear) and the thread pane larger.

I would like to make it go the opposite way, upwards to make the thread pane smaller.

Is there some code, css etc that can make it happen correctly?

Hello, Since the update to Thunderbird Supernova from version 102 upwards, emails in several email folders are automatically deleted or hidden. The properties in the respective folders are listed under Retention rules: Do not delete messages.

The emails displayed in the folders no longer correspond to the contents in the folders. Example: A folder displays: 7, properties in the same folder displays: 1226 with 447 MB. It looks similar in the other folders.

How can I ensure that all available emails are displayed in Thunderbird again?

A repair with *.msf does not help.

Many thanks for your support. Erwin

If you have enabled the Menu Bar, maybe you find it is the same colour as the Unified folder and want to change it. Maybe you want to change the colour of the opened Tabs. Read the information below to help you use 'userChrome.css' and tailor make your own Thunderbird.

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!!

Thunderbird recently upgraded (?) to Version 15 on my Windows 10 laptop. Since them, when I go to look at the "Trash" folder, I get the message: "Unable to open the summary file for Trash on username@gmail.com. Perhaps there was an error on disk, or the full path is too long." I was able to fix it temporarily by restarting Windows 10, but the error is back a few hours later.

Installed thunderbird for the first time. Mouse scroll wheel doesn't work in the inbox, in message view, in settings, or in calendar.

The scrollbars are visible, if I click and drag them they work, if I use the up/down arrow keys the window scrolls as expected, it's just the mouse wheel doesn't work. Mouse wheel works in other programs ex firefox.

I disabled smooth scrolling and autoscrolling but the issue persists.

I have a userChrome.css to change the color of unread messages in the "list of messages" pane to orange:

/* 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;

}

This worked fine in TB 102 and prior. When I upgraded to TB 115 this no longer has any effect. I'm not sure if the userChrome.css is being ignored or if the styling elements in userChrome.css have changed.

I'm on Windows 11 and userChrome.css is located in 2 places: C:\Users\$username\AppData\Roaming\Thunderbird\Profiles\$profile.default\chrome\userChrome.css C:\Users\$username\Application Data\Thunderbird\Profiles\$profile.default\chrome\userChrome.css

So I want my UI to look proper so title bar at the top, with the title only, menu bar below it, and the rest tabs etc below that, you know like i trained my brain for the last quatre century.

Unfortunately with this new supernova UI this is messed up, see attached image. I consider this a UI bug its absolutely counter intuitive, please fix.

Also the font looke now more washed out in comparison with the previouse build, I want my font crisk #000000 on #FFFFFF no gray or grayisch or anything, the UI ist nto an art peace, its a tool, as simple as that.

What is going on with the new TB client? I now have no access to my Sent mail. Nothing showing in Unified Sent mail and no more access to individual account sent folders. Major mistake upgrading. To elaborate, the Unified Send folder has never displayed sent messages and this is a known issue in bugzilla. But we have had the option to expand this folder to show the individual send folders in order to view sent messages. Now, there is no way to expand this folder, so the only way to view sent messages is to choose All Folders from Folders Mode. This defeats the purpose of Unified Folders. It's a step backwards. If there are no plans to address the Unified Send folder, then why was the option to expand it removed. Makes no sense.

In thunderbird 115,

I have clicked "hide message list header" and cannot find a way to show it again

how do you unhide it ?

https://support.mozilla.org/en-US/kb/getting-started-thunderbird-main-window-supernova#w_4-message-list-header

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!
