When I try to edit an address book entry, I get a partial part of entry. I can only see first name and unable to see or edit anything else. Using windows 11, seems to create problems in Thunderbird.

Hi, I’m using Thunderbird with a Yahoo Mail account and I’m seeing two Draft folders in the left pane:

Drafts Draft

Their IMAP locations are different: imap://…/Drafts imap://…/Draft

Thunderbird only saves drafts into the Drafts folder (plural). The Draft folder stays empty, but it always shows up.

What I tried so far: • Account settings → Subscribe Unchecked “Draft” there, but it doesn’t save. After reopening Subscribe, it’s checked again and the folder is still visible. • Restarted Thunderbird multiple times. • Server Settings → disabled “Show only subscribed folders”. • Checked folder Properties, but there are no options to hide it or control visibility, so it looks hard locked by Yahoo.

Conclusion so far: Yahoo seems to force both system folders via IMAP and ignores unsubscribe, so Thunderbird can’t hide or remove “Draft”.

Is there any supported way in Thunderbird to permanently hide or ignore the extra Draft folder for Yahoo accounts, or is this a known Yahoo IMAP limitation?

Thanks

Lately, when I try to click on a different mailbox or message , nothing happens. repeating clicks sometimes works, and sometimes i have to first click on what I was previous viewing to get what I want to highlight, or click on different areas of a message or mailbox to get it to work. I am on mac tahoe 26.2. Did not have this problem before. What can I do to fix this problem?

Thanks Dan

My Spectrum-TB connect was functional yesterday but is not working today; NO password or setting changes! Contacted Spectrum and was able to successful send an email from Spectrum's online webmail to a gmail account.

Hi, great mail client! I have two email accounts and would like to suggest:

(1) Switching from one account to the other takes too many clicks. By using the three lines top left, I would like to get to the ACOUNTS LIST directly. That could be implemented as a switch in the settings or as an own button/icon on the pages of the mail items.

(2) Next to the sub directories I would like to see the number of total mails per folder - not only the new ones. The desktop version has that feature.

Thank you for considering my suggestions. Best regards, Gert1

My problem is that JPEG attachments don't open, though PNGs do. I've got Original HTML actioned. Defaults are set to Fastone Image Viewer. Right click shows options but "open" doesn't work. Any ideas?

Hello,

since some years I use the facebook calender url in the calender tab.

Since some days the are no entries shown anymore.

The same calender url is correctly used in google calender (web & app)

The facebook url is as followed:

https://www.facebook.com/events/ical/upcoming/?uid=100001094911980&key=XXXVO6gUO0v9U63j

It would be helpful to have a solution or at least an explanation for this problem.

Hello,

I would like to report a problem I experience using Thunderbird on a Mac (see configuration below). In some circumstances (that I am not able to determine), when deleting one message in the inbox (unified Folders mode), the message list is not updated/refreshed i.e. the deleted message is still appearing but in fact the content is the next one. This is very annoying as we may remove messages wrongly: the messages we want to delete are not the one we see in the list.

I am using Thunderbird 140.7.0esr on a MacBook Air Sonoma 14.7.1

Are you aware of such a behavior? What can I do to overcome the problem?

Thank you for your help

Best regards

P. Clarysse

Sorry - I feel as though I'm monopolising this forum at the moment!

In my Menu bar, I have Delete, but, using this, I can only delete emails from the Unified list, not individual accounts. I CAN delete from individual accounts if I select the email, right click and select delete. Seems odd

My Computer in Spain worked perfect wit my Emails until about 5 years ago when you upgraded thunderbird

Since Then it will not recognize my LOG IN passwords for both my Google email and my Plusnet email

I have had to access Gmail via there website but I like your set far better

I have had to access plus net via web mail which is very basic

Both Passwords work perfect in England

I have now set up another Computer and this time Thunderbird does recognize my Gmail password but still tells me my Plus net Password is not correct

I contacted Plus net last December from England and they confirmed that the Password is correct Have you any suggestions as to how I can solve this problem

I use windows 7 ON ALL MY COMPUTERS

Yours sincerely

good day....ii hope someone can help. the other day i was accessing my yahoo account spam folder and by accident, i deleted the spam folder instead of emptying it. the spam folder is now sitting in the trash and i'm unable to remove it from there. when i log into my actual yahoo account, the spam folder is where it's supposed to be and not in the trash. i tried removing the yahoo account from thunderbird and reinstalling it in hopes that it would rectify the problem, but it hasn't. does anyone have a solution?? i would greatly appreciate any help you can offer. thank you for your time...mike s

Hi there! I and my colleague encounter some bugs with Thunderbird and we would like to seek your advice in regards of the issue.

1. <user a@citizen-systems.com.hk> was supposed to get a cc copy of the email sent by <user b@citizen-systems.com.hk> at Mon, 12 Jan 2026 09:35:19 +0800 but it never reached. The receivers, namely <user c@systems.citizen.co.jp> and <user d@citizen-systems.com.hk>, however, were able to get the mail. <user d@citizen-systems.com.hk> and <user a@citizen-systems.com.hk> are working at the same office and under the same network. Network provider checked the protocol, router, traffic and firewall are working as normal.

2. <user e@citizen-systems.com.hk> found a number of emails that she kept at "Inbox" disappeared on 12 Jan 2026 morning +0800.

She is unable to find it anywhere at her whole mailbox but has to ask the senders to resend them to her.

It would be very much appreciated if you can check and advise how to prevent the issue from happening again.

if I type a hyperlink into the Calendar description field it does not link to the url.

The mouse pointer does not change from a cursor to a pointy hand when I hover over it

I have also tried using the 'Link' button and that creates a blue/underlined url like a traditional clickable link but the result is the same as before.

Please help troubleshoot the problem, at the moment I'm having to copy and paste every link which becomes tedious when there are lots of links

Thanks

How could I setup a complex sorting rule? This rule I wish: 1. Sort by date and Group 2. sort Starred Mails at the top and unread mails second. 3. Group this also by DiscussionTread (Starred mails out of context is not helpfull)

I also would like to use this sorting on Android.

I have a windows 11 pc with thunderbird 147 installed. It worked until Jan 16th, 2026. I added the account to my Linux pc that has thunderbird 140.5 ESR inststalled and it works fine with the account from the windows 11 pc.

I have TB setup to allow customstylesheets with userChrome and userContent.css files generated. I have userChrome setup to my liking. Now I want to modify the userContent.css file so that I can set the background color of almost all elements is #222226 except for email text, hyperlinks, and imbedded images. I have this setup now in userContent.css:

body { background-color: #222226 !important; }

{ color: white !important; /* Changes font color to white for all content */ }

This changes most elements the way I want but it also flips the color of other HTML content, embedded images for signatures and other html content so its inverted to unreadable white content with white text. Is there a way to set it up so that HTML content and images are not inverted?

Thunderbird is reporting error "could not connect to server . . . the connection was refused." However, it seems that it reports this error only when there is no new incoming message. And it does not happen consistently.

Thunderbird is version 147.0. Operating system is the current version of Windows 11 on an HP desktop workstation, new 4 months ago.

I have 4 email accounts set up in Thunderbird. Server settings for the accounts are set to check for new messages at startup and at intervals of 5 to 10 minutes depending on the account and to automatically download new messages. I have confirmed the server settings for the accounts match the settings specified by the ISP. When there is a new message to be downloaded it seems that it does, in fact, connect automatically to the server and download when Thunderbird does its check for new messages at startup or specified intervals.

When I have open the Inbox for an account and click on the "Get Messages" icon or right-click on the account name and then click on "Get Messages" I usually promptly see at the bottom of the window the messages "Host contacted . . . sending login information . . . Checking inbox for new messages . . . there are no new messages to download." That is true even if I do that within seconds of receiving the "could not connect" error. But sometimes there is a delay of many seconds before the "host contacted . . ." message, and occasionally I never get that response to the click to get messages. When I click to "get messages" I never see the "could not connect" error even if the "host contacted" message does not appear.

I have set to show an alert and play a sound when new messages arrive. The same sound is played when the "could not connect to server . . ." error is displayed. The result is the sound may be played every 5-10 minutes. I can tell that this issue does not happen consistently because I might go for several hours, or even all day, without the sound and without the error message. The occurrence or absence of the error seems to be completely random and unrelated to what I may have open on the computer.

Since I do seem to be receiving messages without a delay in delivery this is perhaps no more than an annoyance, but I would prefer to avoid the annoyance. This is not happening on other computers here which are using Thunderbird.

I want to transfer my files from win10 to win11. I tried to use the thumbdrive but my files were too large. I also downloaded the Wave Browser,, but didn't like that. If I cancel my win10 and reinstall Thunderbird on my Win11 will it transfer? I'm looking for an easy method. I'm 83 and not that tech minded?

I just installed Thunderbird on an up to date Windows 11 PC and unchecked the box Automatically mark messages as read, but it keeps marking all of my messages as read.

Help please!
