How in the heck do you reach tech support for Thunderbird? I have NEVER in my life seen a company so elusive to contacting them. I appreciate the help in here, but there are times when a forum can't help and you need the actual company to be accessible to get that help.

I am about to that point of uninstalling it and throwing it out the office window.

I have relied heavily on the "Open message in conversation" function, because it gave me a tree of messages across all folders (Inbox, Sent, etc.) that was based on the person I was corresponding with.

Now, the function is giving me a tree based on the Subject of the message. This behavior makes it useless to me. I've looked, and I can't find any configuration setting that would control this option.

How can I once again get a message tree based on the correspondent's name, then sorted next by date?

Thanks!

When I type the word "attachment" in version 149.0.2 I no longer get the warning bar across the bottom of the screen. I do have the "check for missing attachments" box checked in Settings.

To install a Windows 10 update (I'm on extended support) I told it to update & shutdown. I fired it up this morning and Thunderbird is asking for credentials. It usually just runs & downloads emails. I enter my password, then a code from authenticator app. It shows the page below in an embedded browser window that has a checkbox and an "Agree" button. I check the box but the Agree button is still disabled. Dead end. I cannot connect & I'm stuck.

Hi, as of 14/4/26 my K9 (Samsung mobile) and Thunderbird (Mac Pro) no longer works with my bt internet account. Cannot receive or send emails. Have checked both in and outgoing server settings and all agree with bts advised settings. When I attempt to fetch in K9 I get error “network error readstringuntil():end of stream reached. Read:””while waiting for’’. When I attempt to send get message “unknown error unexpected end of stream. Contacted BT and they told me all my settings were good. I suspect something has changed at the BT server end. They did say they had relocated?? Any one else suffering this?

When I receive an email that includes a live link it does not work when I click on it. Instead I get a popup error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

I can sometime manage to copy the link address and paste it into a browser but this is not always successful.

Over the last week or so, selecting a link embedded within an incoming email on Thunderbird does not now ensure that the desired webpage will be opened in Safari and other browsers. Shutting down Thunderbird, intermittently enables the proper functional activity of opening the desired webpage. I've discussed this with Apple (iMac; Sequoia 15.7.5) and was unable to identify this as an Apple problem.

Upgraded from `102.15.1` (deb) to `140.9.1esr` (flatpak).

Now for all my Imap folders the default action (double-click) is `Edit Draft` instead of `Open`. This is confirmed by right-clicking and having `Edit Draft Message` in bold at the top of the list.

How can I fix it?

- imported old profile with `⁝` -> `Tools` -> `Import`

- found https://support.mozilla.org/gl/questions/1364428 and tried the addon it recommended but none of the imap folders were flagged as draft.

How the [edited] do I turn automatic spam filtering off? I've literally unchecked EVERYTHING related to junk or spam, but it's still marking every [edited] email that I get as spam. Even addresses in my address book!

Opening a link in email with control key now switches to browser (Firefox). Previously, pressing the control key when opening a link did not switch to browser. This is handy for opening multiple links in an email without switching to browser each time. Is there a setting somewhere to restore the previous behavior?

In den Vorschaufenstern sind in Thunderbird seit Kurzem keine Anhänge mehr zu sehen. Habe ich unbewusst eine falsche Einstellung vorgenommen? Habe alles versucht, keine Lösung erhalten.

Previous Colors add-on is apparently not him compatible with the most recent version of Thunderbird which installed itself in the last few days.

Does anyone know if it updates to that plug-in is anticipated?

If not, are there any similar add-ons available?

Thanks! Bill

Have been using the 104.9.0esr 64-bit release on Windows 11 for some time now (mostly for email, involving a number of email accounts) and have been generally satisfied...

...but discovered when I started looking into switching over to the 145 default release that I have a capital-P Problem. The first thing recommended on making that change is - sensibly - to back up one's Thunderbird profile. Only as far as I can tell, I don't *have* any such file anywhere on my system. [To answer the obvious question - yes, I've got "View" set in File Explorer such that it should be showing me hidden files.]

I have drilled downward through all the USERS subdirectories on my C: drive. "Default" and "Public" have nothing at all (as one might expect). My personal subdirectory has a Mozilla directory under "Roaming", and both a Firefox and a Thunderbird directory therein, but the only things in the Thunderbird directory are an empty folder labeled "Crash Reports" and a tiny "desktop.ini" file.

There is a "Mozilla Firefox" directory under Program Files, but nothing in that hierarchy looks applicable. There is a "Mozilla Maintenance Service" directory under "Program Files (x86)", but nothing there appears relevant. There is a "Mozilla [alpahnumeric hash]" subdirectory under "Program Data", but nothing there appears relevant.

And in fact, I begin to think I have a bigger issue than I thought I did...because the more I poke at my C: drive, the less I'm seeing...to the extent that I'm not at all sure where the Thunderbird program itself (not to mention a quite large accumulation of associated email) is being kept.

Which would be nice to know if one were attempting to back up one's mail before changing program versions....

Receive the following error message whenever I attempt to reply to or forward an e-mail

"Send Message Error. Sending of the message failed. The message could not be sent because the connection to the Outdoing server (SMTP) mail.thorneplumbing.com timed out. Try again"

This has been going on for some time now, but does not happen when I use Thunderbird on my i-phone. Just on a PC. Please advise.

Thank you!

Recently, I exported my Address Books, i.e., Personal and Collected as CSV files. Looking through those files I discovered that not all "Fields" from the Address Book had been included during export. Some of my contacts include three or four email addresses. The CSV Header added to the top of my exports only shows "Primary Email" and "Secondary Email" in the Header. There may also be other Fields of information that are not exported, but I haven't looked and, frankly, didn't expect to have to check my exported files. When editing a Contact if that contact has more than two email address I expected those to be part of the export file. I am running the current version of Thunderbird on my Windows 11 computer and an earlier version on a Windows 7 computer. Both versions of Thunderbird do not export all Field Data from the Address Books.

This is the third time I am sending this request for support. Here was my original request:

"I am a Spectrum user for Internet/email in the US. I recently migrated from Windows 10 to Windows 11. On both platforms I am a Thunderbird user for my email client. My settings are for IMAP (port 993 for incoming and 587 for outgoing) on both Spectrum and Thunderbird. Since migration I am no longer able to successfully send messages but am receiving fine. I have been on Spectrum's help desk and can successfully send and receive messages but when I try to send anything from Thunderbird the send request fails after several minutes. I need help! This is very frustrating."

The first time, I received a response from Manu Audino (Mozilla Support) who told me that his team's responsibility is to assist with restoring access to Mozilla accounts and subscription services. Manu gave me the link for Thunderbird support which is took me here. So I ask again for support to resolve my problem for sending out email messages. Since sending another request for help I have received nothing. I need help!
