Thunderbird Community Forum

I recently got a notification that a Thunderbird update was available, so the update was downloaded and installed.

Next I went to my inbox to tidy it up, by deleting some items and archiving some that I wanted to keep. On looking at the 2026 archive none of the items where found.

Why has this happened and is there any FIX ?

Maybe I have not found where to set it, otherwise it is a .change request.

When creating a new message and entering a name in the “To” field, all email addresses for the recipient are displayed for selection. - Order as in the address book - The one marked as “Default” is neither the first nor identifiable as such. The order in the address book cannot be changed either. Thank you --- [German] Als Standard markierte Adresse wird nicht als Erstes angezeigt. Neue Nachricht, Eingabe des Namens in „An“, es alle Email Adressen für den Empfänger zur Auswahl angezeigt. - Reihenfolge wie im Adressbuch - die mit Standard gekennzeichnet ist weder die Erste noch als solche identifizierbar. Reihenfolge im Adressbuch auch nicht veränderbar. Vielen Dank

I have set a custom theme on my Thunderbird on Linux. As you can see by the attached image though, the menu bar is hard to read when you get to the right side. Dark background and dark text doesn't really go together. Is there a way to make the background of the menu bars a solid color or something less see-through so the text can be read? I want a light theme, but I need to be able to read the menu.

My name is Barrie Johnson. I have been a Mozilla Thunderbird user for my e-mail services for many years. In the past couple of days I have been getting messages from Google telling me that my e-mail provider - i.e. Mozilla Thunderbird - will not allow Google to access it, with the result that I cannot get to a current version of my Inbox and there is no trace of my calendar details. Can you please help me?

I recently migrated from a much older version of Thunderbird where I had been using the Mail Merge add on. In 151/152 most of the variable fields are no longer recognised. Below is the list provided by the developer. I can only get FirstName LastName and PrimaryEmail to merge correctly I troubleshot with Custom1 JobTitle and Nickname to no avail. I've emailed the developer. I suspect Thunderbird has changed the names of the fields in updating the Address Book. Has anyone got a current list of variables for Thunderbird since the Address Book has been rebuilt? Thanks, Greg

Win 11, v.153.0 Firefox (default), v.153.0 T'bird.

Lately, when there's a link in an email and I click on the link, it takes me to a Firefox browser that's not my normal one - this new one doesn't have my settings, saved passwords, or home screen default, etc.

What happened and how can I fix it? Or must I wait for another update? (It just now updated to 153.0 and the problem still exists)

It is quite annoying.

Thanks.

I retrieve email from two different servers, one is mine, one for work, All of a sudden last night I got a spam email from my personal email server, that kept coming in over 100 times, but no other email. My work email is fine. I contacted the hosting company for that server, who was supposed to blacklist that spam address, (my Thunderbird junk button wouldn't do it), but I'm still getting those emails only. Thunderbird tells me there are 110 emails (and counting) on the server, but won't retrieve them. I can see them on my phone, just not my desktop. (I have the phone set to leave emails on the server until I retrieve them with the desktop). I thought maybe it was because I hadn't cleared out my Inbox for a while, so I deleted about half of the 30k emails that were in the Inbox folder, but it didn't make any difference. It won't compact because I keep getting an error that says some other operation is in progress, but nothing is. None of my settings have changed, and I'm still downloading what I think are copies of that spam email, since they all have the exact same Send time. My Thunderbird version is current, v 140-13 oesr 32-bit, on Windows 10. What can I do, thank you in advance. Long time Tbird user, rarely any problems. Image of some of the copies of the spam email.

I needed to change my AOL password and when I went to change it in Thunderbird I accidentally deleted the entire entry instead of just the password. Now I don't see a mechanism to reenter that information. I thought it might ask that if I simply tried to reconnect to the AOL mail, but I get the attached when I try even though that is the information I use to sign into AOL

Thoughts?

Thanks, John

The Thundebird calendar in month/week view cannot display a full week next to each other. (full width image attached) No matter what I tried. I tried to minimize the left panel (left panel minimized image attached). That barely gives me the saturday added. But still no sunday. If I select a specific sunday from the list of events above, then the whole panel moves to the right, thereby hiding the monday (attached image shifted right) I have even tried to decrease the font used

Is there any way to get all 7 days visible? Is there some magic trick to decrease the width of the week/month view. Why is this not a dynamic view? Workweek = 5 days, week = 7 days

I utilize a program to scan business cards and need to add these contacts into my contact list in Thunderbird. I know how to add them if the VCF Card is received inside an email as an attachment, but I do not see any instructions on how to add it if it is found locally on my computer or received by text, etc. Thanks in advance, Ken

Has anyone had issues with Thunderbird sending and receiving email? I can only send or receive when my wifi is turned off on my phone.

I've tried deleting the app and resetting all network settings on my Android phone but still no joy.

========================================

A few days ago the left (file) pane went from

- InBox
- Drafts
- Sent
- Junk
- Spam
- Trash

to

- InBox
- Drafts
- Sent
- Spam
- Spam
- Trash

I attempted to change the first "Spam" back to the original "Junk"; didn't work. Have no clue why TBird decided to change the file names on its own.

Any information/direction(s) about how to correct this back to the original?

Thank you / appreciated. Nels

I have 3 computers. Two are running Windows, and one is running Linux. I was pleasantly surprised to find that Linux Mint has Thunderbird built in. I keep the two Windows computers in sync with a file compare program, "Beyond Compare" Are my local folders compatible between the two operating systems so I can sync my Linux Thunderbird local folders with the ones I have stored in Windows Thunderbird local files?

Are txt files stored the same in both NTFS and ext4 systems?
