I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.

I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.

Several things are NOT working correctly, though:

1 - Settings will not open. Here is the message from the error console:

Error: No such tab mode: preferencesTab

   openTab chrome://messenger/content/tabmail.js:758
   openTab chrome://communicator/content/utilityOverlay.js:257
   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open

3 - The hamburger menu in the upper right corner does not open

4 - The spaces toolbar on the far left is missing

5 - Events and Tasks are missing from the menu

6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)

Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.

I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.

Could someone please help me get Thunderbird working correctly?

I asked Thunderbird to archive the emails from the first few months of 2024. It created a 2024 folder under the Archives tab. But there are no emails. They have disappeared! Is there any way to recover the deleted emails?

I use the Search Box on the top line of Thunderbird. I have been double-clicking the box to get to a full-page search entry (Duck-Duck-Go).

As of today (6-Aug-24), this no longer works. The only places to search are the address bar, or a very short search bar.

Did this change in the last update? Can it be restored?

Thanks, Lex Rutter Idaho

I have been using Thunderbird for many years and have previously updated without problem. But upon updating to version 128.0.1esr I suddenly couldn't see my folders or emails (see attached image). However, if I search for an email I will get a list containing the relevant emails, but as soon as I click on an email in the list I go back to the blank screen like at login with no folders or emails.

I have trawled through related fixes and have tried clearing the startup cache, restart and reinstall Thunderbird but nothing helped .

'Have enabled and disabled. restarted, both times. Tried troubleshooting mode, and cleared the cache. Could not find the setting in the config screen. Not sure I was looking for the right thing, anyway. Your help will be greatly appreciated. John Looze

Whenever I reply to an email, Thunderbird inserts a detailed email header above the message to which I am replying. How do I minimize that info to Date-time, Sender, Receiver, and Subject?

I accidentally deleted a POP account and I lost every folder that I had on that account, how can I recover it?

I tried with some recovery programs but it didn't work

When I click the button to “repair a folder”, some e-mails have disappeared.

The inbox file is too heavy and cannot be opened as a text file.

I moved the defaults file to an external HDD and saved it over the defaults file on my computer. I could not restore them.

Is there any other way to recover my email?

I suppose the best place to start is when/where I think this problem started. Approx three to four weeks ago my thunderbird program stopped downloading emails from my server (Spectrum/RR). I say Approx because the problem sort of sneaked up on me without me realizing it was there.

I was using W7 and my hard drive was pretty much full and I was constantly getting messages that my email could not be downloaded due to lack of space. I started deleting stored emails and emptying the trash, which sort of kept me up and running for the past couple weeks. All this time my Gmail account continued to work as it should, downloading every email that was sent to me, but the Spectrum/RR account was spotty at best.

So today I fired up a new W11 computer for the first time. One of the first programs I installed was Thunderbird. When I attempted to set up an account using Spectrum/RR the process failed. I typed in all of the correct information, Name, Email, and Password but the account will not finalize. Instead, I continue to get the same message that the Configuration, Username or Password is incorrect.

I have since successfully logged into my Spectrum/RR web mail, so I know the username and password I am using is correct. I have also talked with Spectrum Technical support, and they have verified that what I am using to log in is correct.

I hope I didn't ramble on to much and someone can help me !

This evening, Thunderbird has updated to the new version (can't see where the version number is held, unfortunately). Whenever I try to download new emails, I now get the message "Error with account [email address]. Sending of username did not succeed. Mail server pop3.iomartcloud.com responded: Mate, the command must be one of CAPA, USER, PASS or QUIT." Mails are still accessible through the mail client on my phone and through webmail, just not through Thunderbird.

I am currently on Ver 115.12.2 (32-bit), but I've had this problem over several versions. I recently downgraded from the 64bit version (for a different reason), it had the same issue.

Old messages in the Inbox are listed twice, including those that have been read. New incoming messages are not duplicated, messages where I've deleted the duplicates are not again duped. Messages that get filtered to or moved to folders are not duped. Old messages that are in folders are not duped.

I have several email accounts in TB, and I only see this on my most active- of course! I have compacted all folders many times and rebuilt the Global Database with no effect. I tried opening in Troubleshooting mode and they are still duplicated. It is a POP account.

I cannot receive or send any emails. Server is not authenticating. This is a sudden fault. Thunderbird is updated to 128.0.1esr (64-bit). Opening Thunderbird shows message "Authentication failure while connecting to Thunderbird imap.gmail.com”.

What is the fix for this?

When using TB today I got messages that there wasn't enough disk space. So I compacted all folders (I may have tried a repair too, I can't remember now). Next thing I find my inbox is empty, all messages gone. In Local Folders the Inbox file is 0 bytes and Inbox.msf is 2kB.

I have a backup of the entire disk but what files should I pull over from the backup to restore my inbox? I tried bringing those 2 files, an Inbox file of 1.9MB and Inbox.msf of 5kB but when I start TB again there are still no messages in inbox. A compact returns Inbox to 0 bytes.

Since trying this new messages have appeared in inbox so I've moved them to another folder.

Maybe I need to restore other files too but what? I don't want to restore the entire profile as I made changes and moved messages around before the errors popped up. So what files comprise Inbox. There are other Inbox files in various folders relating to my various mail accounts but the only ones dated today are in a folder called Mail\smart mailboxes - I tried restoring those too but still no luck.

Any ideas?

Thanks, Dave

Hi,

I'm using Thunderbird 128.0.1 on Mac OS 14.5, and recently (not sure when exactly), none of the normal messaging options like reply, reply-all, or forward are available. I still can start a new message, though.

Thanks.

all of a sudden Thunderbird would not "Send" any email ... a box comes up wanting the password for the Outgoing Server but Thunderbird will not accept the password which is correct and has actually been used before when this same problem happened
