I normally use Fedora but my Fedora machine died yesterday. For a time being I want to use Thunderbird on my Mac.

I have a backup of my thunderbird profile directory from Fedora 42. This corresponds to thunderbird-128.8.0. On the other hand, the current version on the mac is thunderbird-138.0.2.

1. Since the version number is higher on the mac I think I will be able to use the old 128.8.0 profile with the new mac version ?

2. If I do this, I will not be able to transfer my profile back to Fedora when I get it working again (because the version number there is lower) ?

3. Is there a way from me to install thunderbird-128.8.0 on the Mac so that I will be able to transfer my profile back to Fedora ?

I m trying to set up as my third email in thunderbird an account which is mickel@embarqmail.com. It sets up using the manual settings following their server instruction fine. But it will not accept my password. I know it is correct because I can log in on their webmail site. What can I do? Any suggestions would be greatly appreciated.

I currently use the Daily version of Thunderbird V141.0a1 and I am using it to connect to my Gmail account via Imap. Recently the client has started showing two Junk folders, one I am assuming is for the Thunderbird Junk mail settings, which is being shown as being on the gmail server but the folder doesn't exist when I use the web interface into gmail, the second Junk folder is actually the server's Spam folder which the Thunderbird client has recently started showing as the name Junk. If I open that folder it displays the email the server has classified as spam, and if I attempt to rename that Junk folder back to Spam it fails with a message that the Spam folder already exists. How do I rectify this situation?

I tried to use Thunderbird today,.. to find the interface was broken, menus were blank, so no ability to look at anything., and error message inferring there was a menu config issue was all that was shown. I duly removed Thunderbird as a snap install, which took a long time as it seemed to be making a backup to somewhere. I then reinstalled Thunderbird 128.11.0esr (64-bit) on my ubuntu 24.04,.. having setup the isp email credentials,.. all seemed fine,.. I then proceeded to import what I assumed was my old local folders... And this is where things went wrong, as I seem to have lost all my archived 2025 emails,.. I say somewhere,.. as I don't seem to be able to find them, I have used the 'find' command to locate anything with 2025 in the file name,.. but without success. At the moment I have a multi-structured 'local folder' entry, but nothing with 2025 in? I anyone able to shed some light on what I may have done wrong Many tx

I'm migrating an existing Mozilla Thunderbird account/email from Windows 10 computer onto a new Windows 11 computer; I've downloaded Mozilla Thunderbird from the download site onto the new Windows 11 machine and set up my credentials, but initially none of my Local Folders were visible; then I exported the %APPDATA% site where my profiles folder lived on the Windows 10 machine and imported it into the %APPDATA% site on the Windows 11 machine, and now, for some reason, I have 2 instances of my email name, 4 instances of a Local Folders ... and even though I'm getting/sending email from that Windows 11 machine, the Local Folders remain empty and the tools to move inbound emails into them are not working. What should I do?

Thunderbird is set as my default email client on my desktop Windows 10 in the default apps and it's set in the Default Programs control panel but when I try to send a document on my desktop to mail recipient, a message comes up saying there is no email program associated to perform the requested action. It is set in Thunderbird as well as the default mail client. Cortana is no longer accessible on Windows 10 on my pc. Thunderbird is set as the email client in the registry settings, I have only a few Startup programs running on startup and cleared the cache in Thunderbird so I don't know what else to do to fix this?

Can someone please give me instructions ..how to recover and reinstate all my emails history that was in my local folders on my laptop which is using windows 10 pro???? so annoying to have all my folders now empty ... so many emails with important info. PLEAS PLEASE help asap

Several years ago, I switched over to the beta path of Thunderbird... In doing so, I created a new profile for the beta installation, leaving the old one behind in case I wanted to abandon beta... So I had two profile folders; I *thought* they were this:

current profile: c:\notes\Thunderbird original backup profile: c:\notes\Thunderbird.b115

Now, I've decided that there is no reason to retain the old Thunderbird profile folder, since I'm clearly committed to the beta path... however, I have discovered an anomaly... *both* the old and new profiles are periodically being updated!! Thunderbird.b115 is apparently actually my active profile, but Thunderbird was updated just a few days ago.

When I look at About Profiles, I actually see *three* profile folders listed:

Profile: Gorlash: (default: no) c:\notes\Thunderbird

Profile: Derell Licht beta: (default: no) c:\notes\Thunderbird

Profile: Thunderbird beta (default: no) c:\notes\Thunderbird.beta (note that this folder does not exist)

Profile: Thunderbird b115: (default: yes) c:\notes\Thunderbird.b115

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

Is there something that I could do to consolidate all of this into just one folder? I don't even *know* what those Gorlash and Derell Licht profiles refer to... Yes, those are both usernames that I use online, in various contexts, but as far as I know, I don't use them in Thunderbird...

Q1: Can I just delete those other profiles where default is NO ?? Q2: Why is c:\notes\Thunderbird still getting periodic updates, even though those profiles are not default??

I have used the TbSync and Provider for EAS addons for several years to link my iPhone calendar with Thunderbird. These addons are now no longer compatible with Thunderbird 139.0 and have been disabled. What will replace them, the "Sync" button? If so, it isn't working on my installation. When I click on the "Sync" button in Thunderbird nothing happens. I cannot find a location in either setting or tools to setup "Sync" to do what TbSync & Provider for EAS did.

I use TB on windows 10

I have only one contact saved,

When I go to search bar and write a name I get a huge list with past email accounts from an older profile which is deleted is not the default in anything ...

I have selected one of the emails and it gives me this...

a page with the full list with all the addresses (200+) on the left and the messages that were included (check photo)

how can I delete them????

I have not been able to connect to SMTP server. I am using version 139.01. I removed my account after having issues with my VPN (Proton) and tried to reinstall. I get the error message that settings for account cannot be found. I do have a backup copy of profile it that is necessary. How do I recover my account?

I am trying to upgrade from 128 esr version to the new 139 version. I tried several ways to transfer data from the old version to the new version - I tried to export and import a the Thunderbird zip file. I also tried to open profile manager and creating a new profile that refers to a copy from my old version. Nothing has worked. In the old Thunderbird 128 version, if I select Help and Troubleshooting Information and then Open Folder next to the Profile Folder I get an error in Thunderbird that it can’t find my profile. I get the same error message when I go to Tools, export and select "open profile folder." This in spite of the fact that the old version continues to correctly display my contacts, tasks and events

After several hours of this, I finally decided to download version 139 using the standard Mozilla set up even though my Thunderbird 128 version is located someplace else. So, at this time I have two working versions of thunderbird on my computer – the old 128 version with all my data and the new 139 version with no data.

I think I need help figuring out which Profile has my contact, calendar and task data. Then I need help getting it to the new version.

Thanks

When the add-on "Copy Sent to Current" is running, the Composition Toolbar in the Compose Window is blank and therefore there is no "Send" button. What am I missing?

I've attached two screenshots - one with Copy Sent to Current disabled and the other with the add-on enabled.

I've imported/exported everything I could from a Win10 to a Win11 one. I then went to the toolbars under "view" and made sure they were all checked. Next, I clicked on "customize" and selected (single click) what I wanted to add to my toolbars in the mail window. The "save option" was greyed out. How do I save these to my toolbars?

I continue to get the following message every time I open Thunderbird: Mozilla Thunderbird Email wants to access your Google Account at xxx@gmail.com

I have deleted the account from Thunderbird and made sure inside the Google Email account there are no permissions set up to allow Thunderbird access.

How can I get this to stop?

I'm using Thunderbird version 128.11.0esr on my Windows 11 desktop computer.

I have many email accounts in Thunderbird and Thunderbird automatically forwards email from some of the accounts.

Occasionally I will see an error message: "Send Message Error. Sending of the message failed. An error occurred while sending mail. The mail server responded: Error sending message for delivery... Please check the message and try again."

Can I trace this error back to determine which email account is causing the error?

Thank you.
