Thunderbird サポートフォーラム

I am a long time Thunderbird email user (back to Eudora) and never have had a problem until recently with 115.2.2 . I lost all of the contents of my Sent folder. I see the new Thunderbird sent email folder icon but it is empty.

Please help me find my lost sent emails and tell me how to prevent this from happening again. Thanks you in advance for your thoughts on this issue. chuck hall

The 'Message Header' is the area above where the message content of an opened email is displayed. It typically contains a set of buttons - Reply, Forward, Archive, Junk, Delete and More It shows From, To, Subject and Date It may show other information depending upon settings and type of email.

Do you find the spacing between eg: the 'From' line and the 'TO' line is too much? Do you want to reduce this gap? If yes, then the following information may solve your problem.

Have you discovered that you cannot raise the 'Message Pane' as far upwards as in previous versions? This is because the developers have increased the minimum height of the Thread Pane otherwise known as 'Message List'.

the hourglass icon comes on whenever I click anywhere in the inbox, and the program makes me wait too long. This is a new problem with the so-called new thunderbird. It is not an improvement; it was made worse. Please fix this bug. And where it says report a bug, I can't report one.

The problem affects Mozilla Thunderbird v.115.3.1. I have local folders with subfolders and subfolders within them. Until now, subfolders expanded only after clicking on the folder. And it was very convenient. Now subfolders expand as soon as the mouse hovers over the folder name. This is very uncomfortable. Is it possible to return to the previous solution in the settings?

Hi, In TB 102 the menu toolbar was still above the button toolbar, if I am not mistaken. In TB 115 this seems to have changed... I could not find a way to customize it back as it was. Pointers anyone ? Thank you.

Hi,

after updating to new Thunderbird 115.0 menu bar appeared below tool bar and I couldn't find a way how to put it above as in previous versions. Please see attached image. Any idea?

Thank you.

Hi,

My Thunderbird auto updated this afternoon to 115.3.1 . Now I am only seeing message headers. The body of the messages has disappeared. I'm not seeing anything on the bottom half of the screen, not even the message tool bar where you can delete, reply, etc..

Strangely -- the very same thing happened to me six months back with a secondary account, but my primary account was unaffected. So I was using the email interface with one email address (same domain name) which worked fine, while the secondary one only showed headers, and not the actual messages.

NOW-- after this download, the secondary email address account is showing both the headers and the messages, while my primary account is only showing the headers.

PLEASE HELP. Posted here six months ago for the previous time but never got any solution to the problem then. Just lived with it, as it was a secondary email address, but I will have to leave Thunderbird if I can't get the primary address showing actual messages soon.

Thanks in advance for your help!

Hello, I have been using a custom userChrome.css in the past, but it does not work since I upgraded to 115.0.1

Is the userChrome.css still supported? I have turned it on in config mgr, and tried every resource I cna find on the web, but my userChrome.css is ignored.

TIA...

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,

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?

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.

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

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 ?
