I used to use these add-ons

Old Icon Phoenity Buttons Phoenity Icons

to make Thunderbird more attractive, but now I'm having constant problems. The interface has become schizophrenic, and every time I open it, the icons have a different style, so I've been forced to disable the add-ons.

The question is, are there any supported add-ons left? I can't find any on the website. :(

Hi, Is it possible to change the Thunderbird folder pane (folderTree) appearance to look like the Thunderbird 102 style shown in your screenshot (smaller, more compact, and using simpler icons). Like imge below this

I using thunderbird version 115.10.1 and i try use CustomCSSforTb but it only change icon and colors. I cant change the tree folder style.

I have an email account with BlueHost, which also hosts my web domain. A couple weeks ago I stopped receiving emails and contacted BlueHost tech support. The agent had no clue why I wasn't receiving email. She said "Can you please click on acocunt actions and remove the account and re-addd it. [sic]" I did that, and I was again able to receive emails. But then all my old emails -- sent and received -- had disappeared. BlueHost was able to restore my Inbox emails back to May 19, but was not able to recover any Sent emails. I have a backup of my Thunderbird directory from April, but would like to recover all of my old emails, which apparently still exist because my current Thunderbird Profiles directory contains files corresponding to deleted email folders. For example, my Inbox had a subfolder -- call it ABC -- that was deleted and is no longer visible in my Inbox, but I can find files ABC (no extension) and ABC.msf in my Inbox.sbd folder. My Sent.sbd folder also contains files ABC and ABC.msf. These folders are in C:\Users\aaa\AppData\Roaming\Thunderbird\Profiles\aaa.default\Mail\mail.aaa.com (with "aaa" representing my personal identifiers). mail.aaa.com contains files Inbox, Inbox.msf, Sent, and Sent.msf, which seem to contain my old emails. (Inbox is 132,151 KB and Sent is 289,829 KB, and the file dates are from a couple weeks ago, when I removed and re-added the email account.)

Is there a way that I can recover the old emails?

Failure to download email from Optus. I have spent a number oif hours to no avail talking and typing with the Optus staff regarding this problem. 1. I can send email from TB but cannot receive. 2. I can see the incoming emails in their Webmail site. 3. Optus confirm my settings are correct for both the mail server and SMTP server. When I go to Settings> Security > Passwords > remove server so I can re-submit my password, the only one showing is the SMTP server. Should the incoming mail server also be shown?

I am frustrated and ready to dump TB but have bee with it many years and don't want to start again with another programme as I am 83 and am partially blind. Please can anyone assist?

My old Windows10 computer died, but I have an external backup with my Thunderbird profile folder. In the meantime, I have been able to resurrect an old Windows10 computer to continue receiving email, but was not successful transferring the backup profile. Thus, I have "new" profile on this second computer containing only the recent emails not in the backup profile.

I've purchased a new Windows11 computer. My question is: How can I merge my old emails in the backup profile with the recent emails received after the backup was made? In other words, is it possible to merge two separate profiles into one? Thanks.

Greetings,

I recently updated to Thunderbird 140. After the update, I am unable to open .eml files by double clicking on them. I receive message window (attached image). If I do File->Open->SavedMessage I can successfully open the file. Please advise how I can get Thunderbird to open .eml files regardless of the instance of Thunderbird that originally created the file.

This happens about every three or four major updates: After the programmers monkey with the interface, part of my personalizations disappear. This time, it's the text menus at the top of the screen. (And it's two computers since the last time I had a solution to this.)

The "menu hamburger" is not sufficient for touch-typists. I want the icons off to the right of the text menus, on the same line, the way it's been possible to establish since Tbird was in the low-30s for version numbers. Instead, the update refused to respect my personalizations, and hid the menu bar completely and makes it impossible to combine with the icons. I dimly recall that there was an about:config solution to this in earlier versions, but can't remember or find it (or confirm it would work with Eclipse).

I'm recovering from a HDD crash that damaged the boot sector only, my files were unharmed. I am/was using Thunderbird. My Roadrunner IN BOUND e-mails were saved on the Roadrunner servers and successfully downloaded to the new Thunderbird client installed on my new hard drive. But none of my SENT e-mails were stored by Roadrunner.

I want to find my old HDD file of SENT e-mails only and move it to my new drive so they'll load in my new Thunderbird. Roadrunner support said they should be on my old HDD but because my old Thunderbird settings were in POP while my new Thunderbird is in IMAP, the file may not be compatible. Of course they gave me incorrect settings also, so not sure if that's accurate.

Regardless, even if incompatible, I want to have some way to access my old sent e-mails for tax and other purposes.

Please help!

Thanks Theo

How can I move emails within Thunderbird? I want to move emails from the Sent folder of my old email account to the Sent Folder of my current email account. Emails don't move when I right-click on them and select "Move to" and then select the destination folder. All that happens is that the Thunderbird status bar reports: "Looking up pop...." "Connecting to pop..." "Connected to pop..." "Checking mail server capabilities."

Dragging and dropping a folder into another folder opens target folder. It shouldn't do that. The target folder should simply accept the folder being dragged into it and stay closed, as it always did since inception until a few versions ago. It is sooo annoying to always have the target folder fully expand when I have not desired it to do so! How can I prevent that from happening? Any help much appreciated.

when i oppened tbird on windows 10, it showed a page to obly my for a donation. i had made a donation short ago, but eventhough, i just made another one time donation. when i open tbird again, i can not get out of the donation page. what should i do please???????

When I click on a folder with multiple messages, each of which has a thread with multiple messages, all of the threads are automatically expanded. If I collapse each message thread, leave that folder, then return to that folder, all of the message threads are again fully expanded.

Is there a way to stop this automatic thread expansion each time a folder is opened?

Hi,

I'm trying to add another account to my Thunderbird client (already have 2, a IMAP account, and a Hotmail/Live/Outlook), but i keep getting the error "Exchange auth error" and no possible way to manually configure the server or anything, despite the mail server not being an exchange server. Following this, it just freezes the view, although i can close the popup by pressing escape.

is this a bug in the most current version of Thunderbird, or am i doing something wrong?

I'm having an e-mail emergency, and will be very grateful for any assistance. Running TB 128.12.0esr (32-bit) on a 64-bit Win10 PC.

Earlier today, Thunderbird stopped sending or receiving via my main account, on an Earthlink-hosted domain that I own. Turned out that I can still send from accounts on two other domains, one a shared-hosting domain that I own; the other is Verizon/AOL. But I cannot seem to download from any of the three domains.

I checked all the SMTP and POP settings, which worked a few hours ago and have not changed. Restarted Thunderbird several times, inlcusing in safe mode, and rebooted the PC twice. Clicking "Get Messages" - globally or by account - does nothing. The thin blue "working" bar at lower right keeps scrolling, even if I press the Stop button.

I would prefer not to mess around with setting up new profiles and all. Can anyone here please suggest anything less complicated and risky that might get mail working again?

THANKS in advance!

We have Thunderbird set up to auto-connect to Plusnet's "Force9" emails, using a saved password, on a desktop machine running on Mint. It's always worked fine until today, when it gets to "Host contacted, sending log-in information"

then after a long pause a box pops up with,
"sending of password for user [ xxxx] did not succeed. "

It offers me the option of entering our password manually, which gets the same result.

If we log in on Firefox via their webmail portal, using the same password, it opens well enough, it's just much more clunky and slow to use than Thunderbird normally is.

Any advice will be welcome, please. Thanks.

I've got Windows 10 set up for a custom 'blank page' background color through a registry edit; I find a light gray-green much kinder on the eyes. This color came up just fine on a New Message (compose) page in Thunderbird until yesterday, but seems to have been broken by a Windows 10 Update yesterday (7/9/25) to Version 10.0.19045. My custom color still appears behind Microsoft system and app pages (Word & Excel), but no longer is the background for Thunderbird or Firefox, although it does appear behind address bars. Any ideas on why or how to fix would be most welcome.

I cannot deliver emails with attached images. This has only started being a problem with upgrade to Win 11 64 bit 24H2. The message shows up in sent with the image.
