Thunderbird Support Forum

I haven't done anything new recently (no new add-ons, no changes of any kind...) but all of a sudden Thunderbird is extremely slow. Clicking from one folder to the next takes a few seconds, clicking from one email to the next takes a few seconds...

I've compacted all folders, repaired all folders, made sure I'm up to date (115.8.0 (64-bit)), so I'm not sure what else to do.

The folders I'm working in are all 1 GB or less.

I have 2 active extensions; remove duplicate messages and smart templates. Disabling them did not help.

What I did notice, and I assume this is part of the problem, but can't be certain, is that after doing a repair on my inbox, dozens of emails suddenly appeared in the inbox (that had previously been filtered and moved to other folders). Things did speed up for a little while, but then slowed down again. Repairing inbox again caused filtered messages to appear in the inbox.

In other words, I've been working as normal, messages have been filtering to the appropriate folders as they come in (never showing the inbox just going right to the subfolder), but suddenly these messages (after repairing my main inbox) are now appearing in my inbox, at the time they originally came in (they are still in the subfolders as well).

Any thoughts as to what's going on here?

Thank you.

Hello! I have been having an issue of character encoding being off in Thunderbird version 115.8.1 (64 bit). Recently, my emails have been going out with extra characters in spacing. All the previous posts on this mention an option that I can no longer see in this version. Is there an update to this?

Thank you,

I have tried to download FireFox, but my computer doesn't have enough space. My email options do not let me delete emails, stating an error, that there is not enough disk space. Here is the message "There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again." I delete all emails from my trash folder, and with it empty, it still does not allow me to delete from the inbox.

I am constantly having to apply the old "Properties--Repair Folder" fix due to incoming mail not showing in my inbox. Is there a more permanent, comprehensive fix to that issue, or am I condemned to that "cure" every time I open Thunderbird?

This is the second time I have had to downgrade Thunderbird because of my emails not showing. Any of them no matter what folder. Last time it happened I skipped an upgrade and everything worked properly but I only hope the same applies this time. I have used Thunderbird for must be over 20 years so not a newbie. Fedora 39 (64Bit) with all current updates and Thunderbird 115.3.1 (64-bit) after downgrading from 115.8.1. Years ago I contemplated writing my own email client but decided against it. Two things in programming KISS = keep it simple stupid and if it isn't broken DON'T fix it. Thunderbird for me had been rock solid for so many years that I am now very disappointed. Thanks though to all the good programmers of the past

According to Gmail guide for setting up Thunderbird: ""When I delete a message," select Just mark it as deleted." I have done this, but when I delete a message the message is not 'lined through'. [It did work when I first setup the Gmail account, but has since stopped working.]

When I check for email the message is removed, but it's hard to tell what messages I've deleted in my inbox before checking for new messages.

Aside from this problem, everything else seems to be working properly.

Since some weeks I have problems with getting and sending mail through Thunderbird via Gmail.

When I push the download symbol Thunderbird tries to get mails but nothing happens. Then after a while mails might be downloaded.

When I send an email I sometimes get error message that it could not be sent. And that the email can be copied in a draft-folder.

I use imap.

Kind regards Johan Lindeberg

This has happened since Supernova. The previous versions also had count problems, but different patterns.

I ask for new mail, and see folder pane counts unrelated to the actual local folder. Almost always fewer, often only one of a dozen new messages shown. The bright unread folder pane icon and highlighted message title seemingly never apply to more than one message. It is rarely the newest message, sometimes randomly in the middle, often the oldest message.

The one account which is set to only manual checking never shows a count or unread highlight for manual checking. Only if it happens to find something on a restart of TBird.

This seems unrelated to the "total message count" option. Enabling that shows all the messages still on the servers, not the counts stored locally.

Would be nice to know if there are unread messages in a local folder without having to click on each one...

I use Thunderbird 115.8.0 (64-bit) on Windows to check 10 email accounts all on the same server. The setup in Tbird for all accounts is identical. I only have a problem with one account.

The problem is that on one account, after a small number of replies on a thread, the Send button becomes greyed out and emails will not save.

The other email accounts continue to work just fine.

Compacting mailboxes does not fix the issue.

Hello,

i have an issue with my email, i have made no changes but from today, my thunderbird takes very long time to open. In bottom taskbar it says building summary file for the inbox.. and it takes about 5minute to load inbox list, "26000 letters." Also i can send but cannot receive any letters and i am missing last 3 months inbox mail.

How can i try to solve this issue without causing more damage or loss.

Thank you.

I don't know why this is happening or how to stop it. Today, for the second time in about 4 months, I opened Thunderbird to find that I'd been flooded with new copies of old emails. They were all marked unread, and I did a random sampling to see that all the ones I checked I already have a copy that has been marked as read, and for some of the older ones, has been archived. Today's influx consisted of 78 messages (it was about 150 messages the first time it happened) ranging in age from last week to June of 2022. I do not believe I have changed any account settings in the last 9 months, either within Thunderbird or at Gmail, where the account is hosted. In each case all the messages were confined to one specific folder--the first time it was the Inbox folder. This time it was a sub-folder named "Receipts". If I have someohow accidentally triggered this, I'd like to know what to change in order to prevent it from happening again.

Hello all,

I haven't opened my email-client Tunderbird since 13.07.2023. I've opened it today and due to automatic downloading with start, it downloaded nearyl 2200 emails.

But they don't appear in my inbox. I can't find them via search. Due to automatical deletion via smtp they're not in my email account anymore.

Can you please help fixing this issue?

When I have moved a message from Inbox to a folder, sometimes it disappears. It is not in Trash or any other folder. I am on Windows 11 and TBird Version Version 115.8.0 (64-bit)

Juno very suddenly refused to accept my password yesterday which is saved on the computer, so I cannot get to my email. Why would they do that and how can I get into email. I got the box that asks for a new password which I filled in, but the site still refused to accept it. Please send the answer to GrandmaDonnaPowell@gmail.com. Thank you.

I just updated to 115.8.0. I have a much older mac without the upgrade and it is not having the same problem as my os 12.6.3 mac. Some of my inbound emails from are being taken over by a particular email from another sender so the message displays as the other sender, as does the from and reply to, but the subject retains the info from the original sender. Three or four emails in a row will all look like the other sender. The other sender was a public radio station. What's going on?

For example, the email displayed below is from one of my vendors, and has a simple message saying Thanks. The subjct line referencing a quote is correct. The rest is not.

I switches between my Linux and Mac Notebook once a day. Everytime i switch a specific email gets moved to the junk folder. Then i mark it as not junk. As long as i stay in this client everything is fine. When i switch the notebook the client on this system marks this email as junk again. When i mark it as non junk and switch to the other system this email gets marked as junk again.

How can i mark it on both as non junk so this behaviour described above does not happen again?
