No new emails appear to have been downloaded since 12.00 GMT on 27.01.26.

Size of file on disc suggests they are there but not displaying.

Downloads working fine on iPhone and iPad.

This has been happening for a long long time - probably a few years' worth of versions. I have just put up with it... currently running Tbird 147 and it just happened.

When editing an email (either the body or the Subject), if you use the backspace button (the one that deletes to the left) to delete some text sometimes the cursor will incorrectly be positioned about 5 or 6 characters further left than it should.

For example, if I had the text: "Quick brown fox jumps over the moon"

If I were to highlight "fox" in the above example, and hit backspace, I would expect the cursor to end up positioned between the remaining spaces after 'brown' ( pipe symbol here is meant to represent the cursor position): "brown | jumps"

But instead what happens is that the cursor ends up somewhere among/before the word "brown". It's always further left than it should be, by 5 or 6 characters.

I believe it only happens when highlighting multiple characters and then hitting backspace. It may be more (only?) prevalent when editing/replying to an existing email. (But I'm still only editing the new portions that I add at the top of the email; I'm almost never editing in amongst the original quoted email content.)

I also haven't ever been able to figure out how to make it happen, sorry. It is just random...It will happen once in an email, but then not again. But it happens frequently - 3-6 times a day perhaps. (Depends on how many emails I am editing.  :) )

I don't believe that I have noticed this issue if I were using the Delete button (deletes things to the right). I don't think it happens when backspacing one character at a time...but it might. I also use Option-Backspace to delete whole words at a time (instead of highlighting the word); not exactly sure if it happens only if highlighting a word, or only if Option-Backspace, or single key press... sorry, it is so random and unexpected that I don't have more specifics.

I have a domain so any email I use comprises of name@mydomain.co.uk

In the past I have given an email address to some dodgy enterprises such as Abbey National plc, and so I get loads of spam to abbey@mydomain.co.uk

It is an utter pain that many spammers use a throw away or random To: address but because the envelope email is abbey@mydomain.co.uk I get to receive it and there is no easy way of searching a folder to find matches to "envelope to".

Similarly it seems impossible to construct filters for an "envelope to" address.

Any ideas?

Neither plain-text nor HTML-signatures are being removed in replies, even though they are at the bottom of the email i'm replying to, prepended by the default -- tag on a dedicated line, as is the standard. I double checked that mail.strip_sig_on_reply is set to true. This happens on two separate accounts configured on my client. Thunderbird Version 140.6.0esr on Tuxedo OS (equivalent to Ubuntu 24.04)

Web info says plenty that does not exist. Eg Showing a context menu with "Delete selected" The web says can delete emails with delete or shift delete. It crosses the text out BUT does not delete any emails. Similarly emptying the spam folder is supposed to happen off the right click context menu. Nothing happens except last entry is highlighted.

Ideally I want to select a group of emails in the inbox with the find option then ctrl/A to select them all then delete key to clear them from the inbox. NB. None of these emails are still on the server, just in thunderbird.

I use the Thunderbird calendar in version 147.0.1. The calendar syncs with CalDav and works great. Although when the reminder pop-up appears i am not able to snooze (postpone) an event or delete na event. Nothing happens and the reminder keeps popping up every 5 minutes (as in the settings) untill the event has passed. Even worse, when i enable show missed missed events, i cannot even delete the old events in the list.

I've been using Thunderbird for many years. My current version is 45.2.0. My computer runs Linux Kubuntu 15.10

So yes, it's ten years old and it's showing its age. I have a new box I built, and have Kubuntu 25.04 installed. It installed the then current version of TB. I have yet to set things up, but migrating is a priority now.

Some solutions say (on ubuntu/kubuntu) to just copy the directory "/home/username/.thunderbird/profile.default" from the old to the new box. I would likely do it by zip, rar or ssh transfer.

If I do that, when opening up TB on the new box, does the data get converted? and if so, is it automatic? It seems to me that after then years, the data format would have some changes.

I'd appreciate any insight on this. Thank you.

I have 2 parallel accounts with the same ISP. As of 2 days ago, whenever I try to send mail, I get this message: “Sending of the message failed. An error occurred while sending mail. The mail server responded: Command rejected. Please verify that your email address is correct in your account settings and try again.” I receive mail as normal. Using the other address with exactly the same settings allows me to send normally as I have for the past ten years! Nothing appears different anywhere in the settings. There were no upgrades that I am aware of. I have since found that I can send from my basic little "travel" computer without issue. Any ideas? BTW, using POP mail settings.

When downloading a ICS appointment file to thunderbird calendar it takes you through 3-4 step for one download. Is there a shorter way to download ICS files to thunderbird calendar?'

Greetings: Running TBird desktop with email provider Fidei. The email portion works fine (can send & rcv emails)...but upon accessing any of the other features, like Calendars or Lists...the content appears for a moment, then the Login dialog pops & my content for that feature goes blank. I'm providing (what I believe are the correct credentials) but it appears not to accept them...popping again. Are there separate credentials I should be providing for the other features of TBird? It didn't used to behave this way. Thanks in advance for any feedback/guidance. Ed in Tampa

Using FireFox browser

If IMAP folders have been deleted from the server, my understanding of the expected result is that they would no longer be visible on the client. Instead they display in an italic font. Is there a way to make these ghost folders go away? I've tried Unsubscribe from Deleted Folders (Folders display but no tick box to unsubscribe) Deleting cache directories etc all to no avail.

Am I missing something here?

140.7.0esr (64-bit)

I have the thunderbird app on my Linux SSD I set up Thunderbird all went fine when I installed my outlook account, I also have windows 11 so I booted into windows installed Thunderbird there and when I add the same account that i used on the linux. For some reason it wont let me sign in it gives me an account credentails error then send me to microsoft to sign in another way, the recovery email address is not the same as the one I have signed into linux on. I checked the password and recovery email I created and Im able to sign in the password is fine and the recovery email is as well. The thunderbird I installed on windows the account I am trying to add the recovery email is someone elses account not mine for recovery and its saying the password is wrong. I have outlook on my windows desktop and can sign in to that account I even signed out and back in again perfect. I checked the recovery email and password on microsoft web site for outlook and my account credentails are fine. I cant figure this out. It works fine on linux and the shortcut I have on my windows for outlook. But wont allow me to set it up on Thunderbird I installed on my windows. Why is it that thunderbird worked fine setting up on linux with my account but not on windows... I did delete microsoft edge a week or so ago I was wondering if that could be why I dont know.

When I try to send my email I keep getting on screen messages from my old BT account continually asking for new passwords which I keep cancelling but it repeats over and ove again. How can I stop this?

bold text As a message was being sent I tried to save it before the message was completely sent.

When the dust cleared all of my saved messages are gone in all folders and subfolders.

I closed Thuderbird and reopened it. - no saved messages.

I restarted my Macbook Air and opened Thunderbird - no saved messages.

All software was up to date. All other programs seem to be OK.

Now what?

Hello,

As per title, when I step on a new message not belonging to the first thread, the first thread expands automatically. This does not happen when I step on an already read message. I also tried to mark old messages as unread, and the same thing happens. Apparently, it started doing this today, which sounds weird as thunderbird last updated on the 15th, but I didn't notice this type of behaviour before today.
