Thunderbird Community Forum

I am using zebra-striping for my Thunderbird email (78.14.0, 32-bit), alternating between white and light green. This is generated by the following code in my userChrome file. (The forum seems to change my code after it's posted, but the attached screenshot shows the actual code):

/* Light green, high-contrast zebra stripes in message list */

1. threadTree treechildren::-moz-tree-row(odd) {

-moz-appearance: none !important; background-image: none !important; /* background-color:#99E02E !important;} */ background-color:#EEFFBB !important;}

When the selected message is a white-stripe, the color switches to a light blue to make it stand out, but when the selected message is a green-stripe, it remains green and is only outlined in light blue, which makes the selected message difficult to identify.

How can I override the zebra-striping for *any* selected message (white or green stripe), such that the message is always light blue?

I find the headers annoying. While it displays the information I want to see, it wastes a great deal of real estate in the form of excessive white space between the lines.

I would also like to know if there is a way to remove the buttons since they are already in the top of my program and I don't need it in 2 places.

When compacting local folder in thunderbird I get error message ( The folder trash on local folders could not be compacted because writing to folder failed. Verify that you have enough disk space [which I do] ,and that you have write privileges to the file system, then try again.) and nothing will work on thunderbird afterward.

Hello! What settings must I change to force Thunderbird to use my systems' default browser (Firefox) instead of MS Edge? Firefox is default for my Win10 system, and context handling is set to Firefox also. Thanks!

Hello! After donating, I am still hit with campaign prompts through the Update server. How do I stop these (now annoying) messages? Thanks!

I share an "info@" account with a coworker and we tag emails as done when we complete out work. I can tag "done" from my computer and it synchs with her account. When she tags "done" on her computer the tag does not synch in my account.

I should add that this was working fine until we got a new computer for my coworker and reloaded a new version of Thunderbird. Everything else is synching fine.

I think I am missing something in settings?

Thank you in advance!

I support clients who are globally dispersed and so want to have visibility of an alternative time zone in my calendar. This is something I had been able to do both in Gmail/Cal and in Outlook (both web and desktop); the screenshot here is from Outlook.

Is this possible in Thunderbird? I have looked in the settings, as well as the existing support/articles but haven't been able to find anything.

I'm getting junk mail that uses my wife name as the sender. My wife died a year ago and I do not like seeing her name being used this way. Basically, the email (fake billing) has: her name as the sender my email address real sender address (junk/spam name from gmail).

I need to have any email as she being the sender to automatically go to junk and trash.

Please, tell me how I can do this. I'm getting up there in years, so any help and a "how-to do it", I would really appreciate it very much.

I was not able to "see" any way within Thunderbird on how I can do it. BTW- the version of Thunderbird is: 128.9.1esr (64-bit) and my OS is Ubuntu 24.10

Thank you for your time.

The time shown in the Date column for TB is 2 hrs earlier than the actual time. The TB error console also displays the wrong time.

TB 128.6.0esr on freebsd-13.4-RELEASE-p5

System time is set to and displays as MDT (US Mountain/Denver) $ date Fri Apr 18 12:29:52 MDT 2025

TB error console: Date() "Fri Apr 18 2025 10:31:04 GMT-0800 (GMT-08:00)"

about:config timezone settings: calendar.timezone.local MST calendar.timezone.recent [] calendar.timezone.useSystemTimezone true mailnews.sender.date_senders_timezone false

Mail headers show proper time in mail file: Received: from mail-yb1-f187.google.com (mail-yb1-f187.google.com [209.85.219.187]) ... for <xxx>; Fri, 18 Apr 2025 11:55:40 -0600 (MDT) Received: by mail-yb1-f187.google.com with SMTP id 3f1490d57ef6-e5740c858besf2902470276.2 ... for <xxx>; Fri, 18 Apr 2025 10:55:39 -0700 (PDT)

And display properly in the TB headers display: Date Fri, 18 Apr 2025 11:55:29 -0600

Yet TB displays 2 hrs earlier in the Date column: 09:55

How to correct? I had set the Calendar timezone manually, but it is now set as above. I tried deleting calendar.timezone.local but it is rewritten when TB exits.

With the default settings, it is impossible to open a window without the email tab open. How do I enable this to show just the calendar in its own window. In my workflow, I like to have one window open for my email and a separate window that I keep open with just the calendar. The tab bar is always open when the calendar is open and it's a waste of usable space. Is there a setting to fix this?

Dear Sir(s):

I'm just getting started and have no idea on how to setup thunderbird on my Raspberry Pi 5 computer. Here is what I did: I entered my full name: William Loucks I entered my email addr: wll107@proton.me I entered my password: .... checked remember password then I clicked Continue and got the following: Available configuration

• IMAP
• incoming: IMAP | STARTTLS

127.0.0.1:1143

• outgoing: SMTP | STARTTLS

127.0.0.1:1025

• username

wll107@proton.me then I clicked Done ...and got the following: Unable to log in at server. Probably wrong configuration, username or password When I got to proton.me and put in the same username and password everything works fine. So what can I do now? Thanks, William

How do I configure the new "Local Folders" archive set just created - so they'll be displayed and searchable in the Email folder view?

Thunderbird v128.9.0esr (64-bit) on Linux Ubuntu 24.04.2 LTS

I have archived emails on my IMAP server for some time.

Now to avoid a full quota on the server I have reconfigured the Archive to "Local Folders" and changed the configuration to yyyy/yyyy-mm.

After archiving "fresh" emails and re-archiving from the IMAP server archive folder

I can see the respective sequences of folders under the menu

• Account Settings
• email@account.com
• Copies & Folders
• Archives on Local Folder

and within the file selector menu

• Archives on Local Folders
• Local Folders
• Archives
• 2023
• 2023-01
• 2023-02
• etc

The result in the email account folder shows the old "Archive" folder - but now emptied - alongside new (unarchived) emails.

On interrogating the Archive folder properties the location reported is the (previous) IMAP address.

So how do I:

1. identify the location of the newly created "Local Folders" archive set, and
2. make the Archive folder set display and be searchable in the Email folder view?

I open the calendar "Algemeen" on my Windows 11 installation and see this message:

All calendars are currently disable. Enable an existing calendar or add a new one to create and edit events.

How do I enable a calendar? If I click the three dots next to the calendar "Algemeen" or right click "Algemeen" I and select properties I see it is enabled:

Not sure if this Settings or what.

I was attempting to add a gmail address (one of mine) to Thunderbird. I got what you see in the attached. It's taking up one of my two entire monitors. (I'm writing via the 2nd monitor.) There's no title bar. The listed links don't work Ctrl F4 to close the window doesn't work. It's stuck there (Hung).

AND, "ALLOW" doesn't appear.

I'm going to have to reboot. But I really need to set this up.

Thanks, Kami

Before the last Firefox update, I was able to view jpeg attachments in emails (before and after sending) in Windows phot viewer - now I can't!!?? The options it offers to view are weird - adobe, media viewer etc - rather than before where it was Paint, Picture viewer etc? - and in settings, the ascribing options are the same, and I can't find any other on offer? How can I ascribe something like Windows picture viewer to attachments? (I have managed to get t to accept Photoshop - but that is a slow-opener) Mike

I get this series of 3 error log reports on every Thunderbird startup. I open the ERROR LOG screen and they are there. I can delete them but then on the next startup they are there again.

Is there a setting I can change to correct this?

My ADD-ONS, EXTENSIONS list is empty.

Thanks, BH
