I somehow have a Spam folder stuck in Trash. This can of course be removed if I manually empty Trash, but respawns automatically when I restart TB. I've made sure that the "real" Spam folder is pointed to correctly in Account Settings.

How can I safely (and persistently) remove this phantom Spam folder? Thanks in advance.

When I click "extensions" under Tools > Add-ons and Themes, I get the following message:

Sorry, you have been blocked You are unable to access thunderbird.net

I.e. going from https://addons.thunderbird.net/en-US/thunderbird/search/ to https://addons.thunderbird.net/En-uS/thunderbird/extensions/

This happens in Thunderbird, Firefox and Vivaldi, both from my job or my home network (using NordVPN). Funnily search still works, so I suspect the link itself might be broken. Cloudflare tells me to contact the site owner, but they have made themselves incommunicado and refer me to community support who obviously aren't able to fix the problem!

(It is also disconcerting that Cloudflare asks me to enable cookies in Thunderbird, which is a huge privacy issue. However I get the same error in browsers with cookies enabled, so that is not the real issue here.)

Hello:

In Thunderbird, a double-click no longer opened a highlighted email in a new tab as the 'Classic' setup used to do.

I ended up in system setting for the mouse/touchpad. The 'double click' slider had NO value set to it. The 'double click' test did not work.

I set 'a' value to the slider. Viola! The double click test works. Thunderbird works as it used to, as it has.

SOMEthing put a null value in the system settings. I had been nowhere around that function setting.

I am running Thunderbird 140.7.1esr (64 bit) running on Ubuntu 22.04.

I need to filter some emails, and need to filter by the "reply to" email.

Reading elsewhere, I followed the instructions, and created a new custom tag to filter (and checked in the advanced part of the settings, and saw that under the mailnews.xxxx there was the "Reply-To" header set up.

I then set up a filter to use this new tag (sorry if my terminology is incorrect), and ran it on a mailbox, where I know there are emails with the Reply To email address is present, and not one of the emails was affected by the filter.

What am I doing wrong?

Many thanks for your help.

I was using Thunderbird 153.4.0esr 64-bit and my send feature on GMail stopped working. It just spun and spun with no connection.

So, I removed the GMail account from my accounts list and then tried re-adding it, but only received the following error (see image attached). This implies what? I have an account at GMail already? I have a remnant of the previous working account in my configuration? It was working fine until today.

I'm using the automatically derived ports (993 inbound and 465 outbound). That error message appears immediately after having clicked the "Continue" button.

I am a bit of a noob, and probably out of my depth, so please bear with me. It also is a bit of a confusing situation so I hope that I can explain it clearly.

A while ago, Thunderbird stopped working. Whenever I tried starting it up, I got an error message saying that Thunderbird wasn't responding. I thought there might be a problem with some update so I decided that I would reinstall the program. As I went to back up my profile, I found out that there were actually two profile folders where in the past I would only find one. I chose to back up both, and procede with de- and re-installing Thunderbird. After doing so I tried to integrate the old profiles back into the new installation. At first, I chose the largest of the to profile maps and copied it where I found it before the re-installation. I created a new profile using the old profile folder through the User Profile menu. This seemed to work! However, I noticed something. I have two e-mail accounts running in this profile. One IMAP and one POP. I noticed that the POP account was missing about a years worth of old e-mails. As if it stopped saving them at some point. I figured they must be in the other profile folder I found before the re-installation. I tried creating a new profile with this profile but when starting up Thunderbird afterwards I once again got the 'Thunderbird isn't responding' message. So I reverted back to the first profile I made, the one with the missing e-mails. Appart from those e-mails, it seemed to be working well. To get back what was missing, I tried copying the files in the "inbox.sbd" of the back up that wasn't responding into the back up that was responding, thinking that if it messed something up, I could just CTRL + Z my way out of trouble. It seemed that there were three locations in the functioning back up that I could copy the files into, each having the server name of the e-mail account that I was missing e-mails from. I tried copying the files in each of them, each time removing the files through 'undo' before trying the next location. As this seemed unsuccesfull I tried restarting Thunderbird again (having removed the copied files from all locations) which resulted in the following error message:

In a pink screen that I have never seen before. After this I tried removing all profiles and starting again with a fresh copy of the backed up profile folder as I figured I might have accidentally changed something in the profile folder I was using. This however keeps giving the same error message.

Clearly, I messed something up. But I don't know what. Can anybody help? One last thing I noticed that in the 'Mail' folder within the profile folder, there where three folders with the server name before, now there is only one. I guess this is a clue?

All help is welcome!

When editing a contact in Address Book, after selecting a time zone from the drop down menu and saving the contact, only the first 7 characters of the time zone string are displayed in the contact view. When reopening the contact for editing, the time zone field is shown as empty again.

I'm using Thunderbird on Ubuntu 24 and have some messages in some mailboxes that have lost their headers. I'm trying to fix them.

Early (1980's command line mail & mailx) mbox files were pure text with messages delimited by a blank line followed by a line starting with 'From ' (or possibly 'From: '). When I open a Thunderbird mbox file in 'vi' it is 'converted', or so it says. I'm wondering what this 'conversion' is and why it's needed.

Please could someone tell me what the strict rule that delimits messages in a Thunderbird mbox file is, and what is it that 'vi' cannot handle that requires 'conversion'?

Thanks

Hi I have four IMAP email accounts configured in Thunderbird. Three get email from my servers the fourth from Google mail.

I am finding that one of the accounts emails are also ending up in Google mail, the other two are functioning normally.

I have checked for email forwarding etc and cannot find anything.

I removed the account, leaving the Gmail account alone, from my mobile and the phenomenon stops till I fire up the PC.

Anyone got any ideas?

I like using Threads, to keep repeated exchanges together.

Today, I selected one of my emails, then Edit as New, to edit and send some of the content to a couple others, independent of the thread.

but now, those emails to others are linked to the initial thread with the original recipient. I do not want them to be linked to that conversation thread, but instead for them to be in their own thread if a continuing email exchange occurs with these.

I do not want to remove them from history, but rather to merely break the existing link to the thread involving a totally unrelated recipient.

Hello !

I'm using Thunderbird in the dark mode. When I open the detail of an event in the agenda, the text is still written in black, on a gray background so this is not really readable (cf linked screen shot)

At some points I had similar issue with mails, but I found the little button "toogle dark mode for mail" that allow to keep the dark mode for thuderbird but show the mail with white background and black text.

Is there a similar functionality for the agenda ?

Thanks !

I have two different email accounts in Thunderbird. For the last few days, my Yahoo mail will not download. I can go to Yahoo, but prefer not to. My other account will download. I have just noticed that it seems to be downloading the same eight or nine emails over and over.

Thunderbird in Linux has worked perfectly for me for many year. This is my first ever problem with emails not downloading through Thunderbird.

What could be the problem?

Hello,

There is apparently a bug in the latest release of Thunderbird, which has broken the callbacks for Yahoo! IMAP email using OAuth. Potentially, it may actually be a problem with Yahoo!, and how https://api.login.yahoo.com is attempting to reopen Thunderbird after logging in, as the process has changed. I've already reverted back to the ESR Thunderbird channel once, but on a recent update the issue was reintroduced. Screenshots are included.

Thanks for any assistance.

Hello,

Is there a method to export my emails in EML format instead of Mbox without using third-party software? Are there any settings in the configuration editor that could change the default Mbox format?

Thank you

I was very frustrated that in 156.0.1 (157 as of today) on Arch there is no option to minimize to tray when closing. Now i do not know what is the cause of this, but i was unable to find any working solution ... FOR A PROBLEM SOLVED ~12 YEARS AGO >:(. Eventually resigned to system solution using SysTray-X which eventually worked.

What do I have to do to get help in this Forum? This is the second time I've posted a Question seeking help, and yet again it is being ignored. Do I have join some secret clique or group? If so please tell me?

Due to issues with upgrading from Ubuntu 24.04.1 to 26.04.1, I decided to just start from scratch with a new clean install.

After finalising the install, I copied across my Thunderbird data to the new partition, merging directories as the data copied across. But, somewhere in the transfer I lost about the last two years emails, with only emails up until 12/24 being available.

There are a lot a important emails I need to recover, and I'm guessing they're still on my PC, in the old partition, and I desperately need help to recover them.
