How do I view the messages referenced by the dialogue asking me "Do you want to send your unsent messages now?" This dialogue suddenly started to appear when I startup Thunderbird. The dialogue has two buttons: "Send Now" and "Later." Thanks

So I have gone through many of the suggested actions in removing an email account from Thunderbird. It keeps asking for a password for an email account I no longer use. It was a gmail account. I have removed calendar reminders. I have gone to the profiles. It is not listed. I have uninstalled and reinstalled Thunderbird. But Every time I open the program and several times while using. It asks me for the password. How do I remove this?

A few months ago I installed Thunderbird onto a new PC having previously used it on a previous PC (so I'm not a newbie).. However I'm seeing a persistent issue that I never saw before...

I've a regular contact whose name I won't specify but let's call him Roger Smith. What happens is that whenever I post something on a forum (such as this one) and somebody replies, the replies look as if they came from Roger Smith - even though he's got no connection with the actual forum.

It doesn't happen with every forum - for example it doesn't happen with this one - but it does affect most of them. Has anyone else ever reported this and is there anything I can do to correct it?

Hello,

I want to use TB to access my GMX CalDAV calendar. Basically, this works fine. But completed Todos disappear from the list after a day or so ("Show completed tasks" is checked). If I export the whole calendar to a ICS file, the todos are included though.

Is this a bug or is there a configuration where I can change that behaviour?

Thanks for any help, Markus

Greetings!

I am a lone software developer in my own office.

I do not store my passwords. I type them in every time I log in. It's the only way to remember passwords: type them in every time to reinforce memory.

I want to see my passwords when I type them. I don't want a click option to view them. I want to be able to see what I'm typing every time all the time.

I've been a contributor for a number of years. Please create an option to support my request.

If you need me to program the change, please let me know.  :-) I suspect that it is simply a matter of turning off a property on the entry field. This is my third request.

Cheers, Peter Petropoulos

Hi,

I use the quick filter option very often. I use this to filter my message list by sender I'm a bit "tired" of constantly copying the sender e-mail address -> then pasting it into the quick filter field.

I am looking for an option like "Quick filter by this sender" or something like that Does anyone know how i can achieve this?

Some years ago there was an excellent extension from trusted contributor alta8888 called TotalQuickFilter (https://bitbucket.org/alta8888/totalquickfilter/wiki/Home) but unfortunately it was discontinued

Now in v 150, I can no longer modify the tools in the reading pane. Used to be able to but it seems to have disappeared. Of course layout is modifiable but spacing out the tools (so that I don't hit the wrong button in error) or turning some off is no longer an option. The More|Customize does not do much for what I want. Thoughts?

I am using Thunderbird on a Macbook Pro 13-inch mid-2012, in a POP3 account

Thunderbird 140.10 is generally running fine, except that some sub-folders are not visible in my Thunderbird email tool view. I have a hierarchical

I have tried repairing the parent folders, but that had no effect.

The corresponding .sbd files are clearly visible in ~/<user>/Library>/<profile>/Mail/Local Folders/pop-server.<account> and being backed up in Time Machine backups.

Curiously, there is a much-truncated replica of some .sbd folders in Local Folders named /<folder-name>.sbd, all dated in 2013, yet the folder was created in 2017. I presume these refer to an update of Thunderbird that left some trash, and of no consequence. These are parallel to Archives and Archives.msf files.

Please advise on how to disambiguate this structure and recover views of existing mail folders not being displayed.

OK, so I see where others Thunderbird users have previously asked about why e-mails are disappearing from their Thunderbird junk folder but have a quite different problem. So, when I go to my junk folder momentarily all the mails are present, but then right before my eyes 2 or 3 just simply disappear! They truly disappear and are nowhere in any folder on Thunderbird account -trash, archives, sent, etc. I did the obvious and Googled and there are some informative posts about Thunderbird settings for time-outs and filters and automatic deletion - BUT, BIG BUT all my settings conform already to all their suggestions on these various web posts. So at my wits end I ask the folks in the community if they have any explanation as to why e-mails in junk folder on Thunderbird literally just disappear in front of me. I would be greatly appreciative of any suggestions.

We have bought a new computer from our tech guy before. This time, all was fine except for the Thunderbid calendar. The 20 GB of email files are all there and email still works. Only the calendar is blank. Our guy admits he dislikes Mozilla and rarely deals with it. Is there any way we can find the contents of the calendar? The old computer is still here in our house, but we only have one monitor. I had birthdays, lots of birthdays setup as repeating events. I hate to lose that.

This is odd as we didn't lose anything the last time we bought a new computer from same guy. We already were running Windows 11, so that is not the issue.

Hello! It seems Thunderbird emails are suddenly being 'threaded'. It is causing great confusion in my office.

I need to see each email from a person separately in order to find them easily and also to reply to each one at the time it is received.

Can someone please explain in very simple non-techy jargon:- a) How I 'unthread' messages already threaded AND b) How I stop any new ones being threaded in the first place.

Thank you Tylex

Since yesterday (27 Apr 2026) any and all mail that comes into Thunderbird gets marked as SPAM. I searched online and found people saying that I could reset the junk training filter, so I did this, but incoming mail was still marked as spam. The next suggestion was to delete the training.dat file. Did that, restarted Thunderbird and incoming messages are still marked as spam. The last suggestion was to turn off adaptive junk mail controls. Didn't want to do that because I assumed that it would let spam through. Nope. Turned it off, restarted Thunderbird and two emails from my work came in and got flagged.

I'm running version 140.10.0esr (64-bit) on Windows 11. I am using IMAP to connect to the mail server but it's not running any spam detection software (like Spamassassin). I know this because it's my server and even if it was, no updates have been preformed since the first of this month and this just started happening yesterday. Combine this with the bug that Thunderbird notifies me of incoming mail, even if it's spam (didn't post about this because there are plenty going back a couple of years), is starting to make me look for an alternative.

I had to restart my Mac. When TB restarted during relaunch of the Mac, it was like TB starting fresh. It didn't display my email accounts, or my folders with saved emails, etc.

I quit TB and looked for it in my Applications folder - and I found two versions of TB. Inside the Thunderbird folder was version 140.9.0esr. Outside the Thunderbird folder was version 150.0. See attached screen grab.

I thought I should try launching the newer version (which was outside the folder). So I moved the 140.9.0 version to the trash, then launched the newer version – and it had the same problem. It looked like I was starting TB from scratch.

Next I quit TB (the newer version) and moved the older version out of the trash and back into the TB folder and double-clicked on it. A dialog box popped up saying that the file is damaged and can't be launched.

So I tried launching the newer version again, and it still looks like starting from scratch.

I really hope somebody can help me solve this. I can't access any of my email accounts or any of my stored emails. I use email for work (as most of us do), so this is crippling me.

Thanks in advance for any help.

One of my local folders of email disappeared: it is no longer displayed under Local Folders. A few days ago while using my mouse to move a message into one of the local folders, something happened, a peculiar message briefly displayed. At the time I did <Ctrl>-Z to undo whatever happened, but I didn't see any changes. That must be when the folder disappeared, but I'm not sure.

My other folders are still in place. I can't find the missing folder inside any of the other folders (junk, deleted, archive, etc.). Yet when I search for email in one of the missing folders, the messages are found. When I go into Troubleshooting Information, there is no Profile Directory listed, and when I click on the Open Directory button, nothing happens. (I've gone through the process of transferring Thunderbird accounts to new computers in the past.) I'm using Pop!_OS 22.04 Linux and Thunderbird 140.10.0esr. I backup my laptop using Back In Time. Any idea how can I fix this?
