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.

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!

On latest version 115.3.1 (64 bit) when I click on GET MESSAGES nothing seems to happen for several minutes than after repeated clicks on same suddenly line at bottom shows downloading some number of messages. Is this something I am doing to slow what used to be very speedy process to download messages from Comcast server to my PC?

When I opened Tbird app today, my messages show in various folders but only a list of messages, not a screen to view contents of message being examined. I did not do anything I am aware of to change this and haven't been able to locate setting to turn on the message content view again. Also on list of messages, they are shown but with a much wider spacing (double space?) with lot of wasted blank space. How to correct this?

Thunderbird is not even usable after this update! It crashes constantly trying to read and send emails. Can I go back about two or three versions back before you destroyed it?

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.

Good Morning

I have been using thunderbird "for ever", just recently I open thunderbird only to find my email accounts have gone missing and I have to re-enter them all. All fine for a couple of days then same thing happens. This issue has occured for the past couple of weeks and even goung to the latest update "supernova 115.2.2 (64-bit) presents the same problem. Today same thing again all accounts gone asking me to setup email accounts?????

PLEASE COULD YOU HELP?

Thank You,

John

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.

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 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.

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'.

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
