Performance manager always seems to have a green line doing something

Always indexing/sending - mention of 11,000 messages etc etc

Determining which items to index in Sent....

Is this using resources unnecessarily ?

Thanks

I have been using Thunderbird on my desktop since the end of Eudora, but moving forward from computer to computer has created some problems.

Looking at Thunderbird here is what I see.

LEN POP which is configured as a POP account with the standard folders: Drafts , Sent, Junk and Trash There is also a folder called Archives with subfolders for the years 2021-2025, There are also a couple of special folders Like News and Events. and a folder called xxx NUL with about 10,000 emails for the years 2022 and 2023.

Then here is GMAIL which is setup as a standard IMAP account. (or some reason copies of some sent messages from the POP account are saved here.

Then there is LOCAL FOLDERS which contains again the standard subfolders, and then more than 20 folders which are populatde by mail filters from the inbox. It seem most of the mail here comes from the inbox in the POP account. (I often see a notice like" 40 messages moved from inbox to inbox."

On my phone and iPad I have my accounts set up as IMAP.

HERE'S THE PROBLEM

From time to time the POP account starts downloading thousands and thousand of old emails. Today it was over 29,000 messages. I disabled downloading of messages and ran the duplicate remover on each folder, and got rid of as many as I could, of of course as soon as I clicked "get messages" the 29,000 mail dumps started again. (This does not happen on my phone or iPad).

It has been suggested that I should switch to IMAP on the desktop, but I would like to filter mail into the same local folders using the old filters, which I have developed over many years.

QUESTION So, Is there a relatively simple way to do this.

Thanks, Len

I have 3 PCs , I cant send message from them. Message to my gmail accounts is ok. It happends after uppdate Microfoft 2025-8. Somebody who can help me to send email again? I have same email accounts on a Android phone - everything is ok send and get message.

Thunderbird version: 140.1.1esr (aarch64) MacOS 15.6

After the most recent Thunderbird update, I noticed that one of my local folders was completely empty. When I do a search for an email that was in that folder, the email shows as a search result, but when I click on the search result, it opens a new tab and says 'no message found' - although a preview of the email is visible in the search results.

I have tried restoring a backup of the local folders from my Time Machine backup, and while restoring those files did wind back all the other local folders and emails, it did not restore any emails into the problematic folder, even going back to my oldest time machine backup on the 26th of May this year - when I know the emails were still accessible - didn't help.

It's clear that the emails are still there, in some form, since the search function can sort of find them, however there is an issue retrieving and viewing them.

I am hoping someone can help! Thank you in advance, Claire.

Two days ago I paid to renew my Thunderbird license, but I still am getting a message that I need to renew my license. Also, when I try to write an outgoing email, Thunderbird freezes up, and I have to shut it down before I can use it again. I also lose whatever message I was writing.

I receive a lot of emails that are really just the attachment (usually invoices etc.) So I right click the attachment and save it and then hit the "Delete" button to delete the email to the recycle folder. This has always worked fine in the past but now it tries to delete just the attachment, which is still selected following my save, warning me that it will permanently delete the attachment. This is a nuisance more than anything else. However when you hover over the delete button it describes itself as "delete this message" not this attachment, so the behaviour is both wrong and annoying. I can find no settings that will change this behaviour.

I suddenly can't receive emails anymore. It was working fine two days ago. I've checked all the settings and everything is fine. Finally, I uninstalled and reinstalled Thunderbird. It makes no difference. Receiving emails works fine. See the error message I'm getting below. Please help me.

My Tbird password has gone missing. I can't sign in to email. I looked up saved passwords in Settings>Privacy & security>Passwords>Saved passwords but that password doesn't work either. How do I rest my password?

Starting this week, an increasing percentage of, BUT NOT ALL, incoming e-mails are coming through unformatted, which makes them almost unreadable. In the Cards pane nothing appears except the time stamp. Some examples: id CD/0A-06843-A1BCB986; Tue, 12 Aug 2025 23:15:38 id 09/00-49518-8A0AC986; Wed, 13 Aug 2025 10:26:48 id 24/87-15587-133DD986; Thu, 14 Aug 2025 08:14:41 id 05/94-10997-4184E986; Thu, 14 Aug 2025 16:33:24 I'm running ver. 140.1.1esr (64-bit).

The same messages appear fine in Thunderbird for Android on my phone. Anybody have any clue as to what's going on?

Hi,

since Thunderbird updated to version 140.1.1esr, the changes I made (language changes, display settings, etc.) aren't permanent. That is, every time I close and reopen Thunderbird, the changes disappear.

I disabled my antivirus, but it didn't help.

I found an online guide that suggested checking to make sure the "prefs.js" file wasn't read-only, which it isn't. I have several "prefs" files, but the most recent one is from 2024!

Thanks for any help!

My ability to send email from kay@haushousellc.com from Thunderbird stopped working on both of my computers. Msg came up saying the smtp server had timed out. Walked away for several hours and tried again with the same result. Today, I checked the settings and saw a different smtp server for the email, so I changed it. Still doesn't work inside the Thunderbird environment. A msg pops up saying the imap.haushousellc.com certificate is not valid. Someone may be trying to impersonate and don't continue. So I changed the to imap.netfirms.com. Still doesn't work. I went to Netfirms.com, launched through Roundcube and was able to sent without a problem. I am at a loss! I think this may be a result of the last Thunderbird update. Don't know how you will respond, but kay@allyourstrorage.com will work.

I'm using cards view in threaded mode. When collapsed, the card shows only the name or email of the sender of the first message in the conversation. Is there a way of getting a list of all correspondents to show? Or at least, to show the sender of the last message? This is especially relevant in the case of email chains with multiple correspondents. Currently, whomever started the chain will always be the first message and hence the top-most card. When new people respond, it shows the thread as "unread", however, the name of whomever sent the new email remains hidden until I expand the thread. Is there any way to change that behavior?

I've installed Thunderbird 128.13.0esr (64 bit) on a Chromebook Linux sandbox and copied the email profile from a Windows 10 system.

Emails etc have copied fine and the program works but whenever I open a new message window it opens with zero height & minimum width [see attached image]. In fact any new window (e.g. About Thunderbird) does the same. The windows can be resized but that size is not used when a similar window is opened.

I've tried deleting xulstore.json as suggested in some posts - when Thunderbird is run again the file is recreated but the problem remains.

It looks like some settings are corrupted to the point where they cannot be reinitialised (e.g. location of settings) but I need some pointers where to look next.

'bold text'Thunderbird was locked up. I closed it. I tried to re-open it, and it refused to open at all--just the blue swirl for for a second, and then NOTHING.
