The first fix in the [release notes] says:

"Large virtual folders could be very slow"

What are virtual folders? I can't find anything about it in the documentation.

Is this supposed to fix the ongoing Quick filter issue with large folders? (It still freezes)

Hi team,

I am battling problems snoozing & dismissing notifications for my Calendars in Thunderbird.

In the console I am seeing lots of: `Calendar: Could not find definition for AUS Eastern Standard Time`

How does Thunderbird define timezones, and where can I correct this?

I am running 128.5.1esr and my calendar is Radicale 3.0.6.

Thanks!

I see it as Thunderbird hijacking the resources of my computer to run Firefox and take me to the donation website. I'm fine with the request for money in the Thunderbird screen, I can navigate away from that. Don't open programs other than Thunderbird before I require them.

When I compose a new message and add an attachment, I cannot see it (even when attachment view is enabled). The twisty next to "1 Attachment" toggles up and down, but no attachment pane (1st image). But...

If I save the message as a draft, then reopen it, the pane appears (2nd image)!

Why is the pane missing in the new message compose window?

Problem started with email contents of emails in inbox not displaying in the bottom pane. I tried some of the suggestions in troubleshooting. Then all emails disappeared from inbox. On restarting Thunderbird or when I ask to get new messages, I now get this message : Error with account wynandkok@mweb.co.za Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

Note: the disk has 184 GB of free space.

Hello,

I am in the process of linking my mail account via Thunderbird on my computer. However, I can no longer see my normal folder structure. However, if I link my account via my Android phone using the Thunderbird app, I have the option of selecting so-called special folders (see attachment screenshot 1). If I then select INBOX, my usual folder structure can be accessed again in the linked mail account on my phone (screenshot 2). Why don't I have this option in Thunderbird on my computer? Perhaps I thought I was using an outdated version of Thunderbird on my computer, but I cannot see the version number and cannot check whether I can update Thunderbird or not.

Best regards, Dr. Jan-Christian Raabe

I have seen a custom css workaround solution to add category colors into calendar events. That solution still relies on calendar events having to be categorized in order to support color functionality.

How is it the year 2024 and Mozilla Thunderbird Calendar doesn't support event colors, independent of categories? This feature has been standard in most major calendar apps for literally decades now. All my Nextcloud calendar events are color coded (without categories), and won't sync to the Thunderbird app.

Can Thunderbird please add this functionality?

Up to a few days ago, when someone sent me a meeting invitation by email, I could accept it on my Thunderbird email app (on my windows 11 laptop) and it would be added to my Thunderbird calendar. When I would open an email invitation, there was always a line/bar that would appear below the subject line that would say "this message contains an invitation to an event" on the left side and then buttons with "accept" "tentative" "decline" on the right side of that line. This line/bar no long appears in email event/meeting invitations. On my windows 11 Laptop with Thunderbird version 128.2.1esr (64) bit, that line/bar no longer appears and I can no longer accept event/meeting requests sent to me by email. I could do this before, and I have an example from my old windows 10 laptop using Thunderbird version 115.15.0 (32 bit). Did something change with a new Thunderbird update? Or do I need to change some setting in my Thunderbird version 128.2.1esr (64 bit) app? See attached example of meeting requests received by email on both versions of Thunderbird. The email from the 115 version shows that event line/bar the email from the 128 version doesn't. Any advice? Thanks in advance.

Dear Support Team,

I am experiencing an issue where the "Send to -> Mail recipient" option is missing from the context menu in Windows, despite having Mozilla Thunderbird set as my default email client. Steps to reproduce the issue:

   I have set Thunderbird as my default email client in Windows 11.
   MAILTO links work correctly when triggered from a browser or PowerShell (e.g., start-process "mailto:test@example.com" opens Thunderbird as expected).
   However, the "Mail recipient" option is completely missing from the "Send to" context menu.

Additional troubleshooting:

   I have verified that MAILTO is associated with Thunderbird in the Windows default apps settings.
   The registry keys under HKEY_CLASSES_ROOT\mailto\shell\open\command are set to:
   "C:\Path\To\Thunderbird\thunderbird.exe" -osint -compose "%1"
   I have recreated the Mail recipient.MAPIMail shortcut in %APPDATA%\Microsoft\Windows\SendTo pointing to Thunderbird.
   I have reinstalled Thunderbird and checked MAPI compatibility, but the issue persists.
   Running rundll32.exe url.dll,MailToProtocolHandler test@example.com successfully opens Thunderbird.

Observations:

   The issue seems isolated to the context menu functionality.
   The "Mail recipient" shortcut does not appear in the context menu at all, even after manually creating the Mail recipient.MAPIMail file in the SendTo folder.

Could you please help me resolve this issue? Are there any additional settings or configurations I need to adjust to restore the "Send to -> Mail recipient" option for Thunderbird?

Thank you for your assistance.

Best regards, Ondrej

How do I mark something as NOT spam . It seems over zealous now

I keep having to remove things back to inbox but I used to be able to say NOT SPAM on the previous site

samovar@igelbau.com

In the last few weeks when i look at the Washington Post "The Seven" newsletter e-mail there are words missing from the description of each item. Only the words that are underlined are shown. I have found that if I mouse select the text the missing words show up as white text on a blue background. But if I look at the same e-mail directly on AOL (my mail server) there is no problem. The picture shows what it looks like after I do the mouse select. I don't know how to fix this. Please help. George Mells

Good Day

First ... -> Wayne Mery don't delete this post. This is not duplicate. If You want delete ... delete solved post. Thanks for making me type everything out again Wayne - you've been very helpful.

Back to the topic.

MT new installation - does not remember passwords despite checking the "checkbox" in the IMAP account. This also applies to Google accounts for calendar (non-IMAP account). The password manager is empty. After restarting MT, the same.

I have the same problem as asked in: https://support.mozilla.org/en-US/questions/1440873#question-reply (I can no longer reply to that thread as it has been archived, so I am asking again now in search of an answer).

To reiterate the problem, draft emails are save correctly into the 'Drafts' folder in both Thunderbird and the Gmail web app, but only Thunderbird will correctly delete the draft once the email has been sent. In the Gmail web app, the draft email remains in the 'Drafts' folder.

Why can't Gmail automatically delete draft emails that have been sent? Is there a solution?

I am using Thunderbird 128.5.1esr (64-bit) on Windows 11.

Przenosząc maile do pod folderów (robię to, by mieć porządek na poczcie), giną te maile w powietrzu. Przez długi czas ich nie ma, nie widać. Jeśli potrzebuję się odnieść do przeniesionego maila, to nie mogę, bo go nie ma. Proszę o pomoc, bo to trwa zbyt długo i bardzo utrudnia pracę. Również maile, które się wysyłają, nie zapisują się automatycznie w "wysłanych". Muszę zaznaczyć zapisz w lokalne foldery wysłane. Ta poczta to jakiś dramat, same problemy od samego początku!

Windows 11 23h2 fully up to date, Thunderbird Version 128.5.2esr When in win explorer, right click context menu, send to, mail recipient produces error "no email program is associated......... despite Thunderbird being set as default both in it's settings and in windows settings app defaults with all file types registered,

Suddenly, my keyboard DELETE button will not delete Thunderbird emails. I have to right click and click on rubbish bin to delete. Very tiresome. My delete button works fine on every other programme.

I'm having trouble with Thunderbird on my new Windows11 laptop. I've used Thunderbird for years and years on the old Windows10 one, but can't get it to work right on the new one. The version info it gives is "128.4.4esr (64-bit)"

Specifically two problems. (1) Every time it starts it asks for my yahoo server's password. Even though I check the box asking it to remember it, it doesn't. Under Settings->Privacy&Security (under Passwords)->SavedPasswords, the list is empty. (2) Second problem (may be same as first, but in a different form) Whenever I try to send an email message, it fails. It waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username bill.marshall@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings (which I have done, and all looks OK).

Thanks Bill Marshall, bill.marshall@verizon.net
