I use HTML as my signature. It has been working just find, but lately when people reply to me, their messages were coming in blue text. So today I changed the: Settings > General > Plain Text Messages > Quoted text formatting from blue colour to black (I have no idea how that was set to blue in the first place). that is all I did. Image attached of the change I made.

In any case, after that, when I tried to send a new email my HTML signature no longer displays the correct font (Pristina) but shows only variable text. The HTML file is not corrupt, it still looks fine in the actual file I saved, but, Thunderbird is changing it somehow. Even when I look back at sent files, Thunderbird is showing me the variable text and not Pristina.

Any assistance would be much appreciated. With thanks, NM

I have tried various suggestions, but they all seem to send me to menu options that just do not exist.This is a really old problem and I can't understand why it has never been properly addressed.

Automatic spacing is pretty much universally not standard (It does not occur here.)

So how do I stop auto/double spacing when composing a message, please?

The folders from my TalkTalk account keep disappearing and reappearing. I have tried lots of fixes suggested by a guy who helps with tech issues but nothing has worked yet. Just before it happened, I clicked to 'compact folders' when prompted. I've done this loads of times before with no issues. I have used Thunderbird for a long time and never had this problem before. The folders seem to disappear when I shut down and restart the computer. Yesterday they came back in about 5 minutes. Today they haven't come back and I've had the computer on for about half an hour. Every time the folders come back, they are Threaded (which I never choose) and Ascending (I always choose Descending). I change them back but next time they revert again.

So far, we have: backed up the profiles checked the server settings checked the password checked webmail - working fine refreshed the folders (subscribe) deleted a .msf file

Any other ideas? Much appreciated!

Using TB for many,many years under the POP system, when I trashed an email, it remained until I opened Trash and physically removed it. I had about 5,000 listed and would delete the oldest month on a monthly basis. When I switched to iMap, my trashed messages are automatically being deleted after about a month. I have searched account setting, but can't find any way to reverse this feature. I am running TB in a iMac running 10.14.6. Would appreciate any assistance. Thanks, Gary

Auf der Öffnungsseite erscheint normalerweise links ein schmaler Streifen mit den ganzen Ordnern, wie Posteingang, gesendet usw. mit der jeweiligen Anzahl der E-Mails. Im übrigen Feld rechts daneben sind alle E-Mails einzeln aufgeführt. Jetzt erscheint manchmal auf der Öffnungsseite eine andere Ansicht, ähnlich wie die Konteneinstellungen. Mit mehreren Versuchen kreuz und quer gelingt es dann wieder die normale Ansicht zu erhalten. Vermutlich habe ich mal irgendeine falsche Taste gedrückt, so daß sich die Ansicht plötzlich geändert hat. Könnte sich das Problem lösen, wenn ich Thunderbird neu installiere oder gibt es eine einfachere Lösung?

Normalerweise habe ich die klassische Ansicht, links die Ordner mit der jeweiligen Gesamtanzahl der E-Mails und rechts alle E-Mails einzeln mit Text aufgeführt. Jetzt seht das nach dem Einschalten von Thunderbird so aus: links nur teilweise die Ordner ohne der Gesamtzahl der E-Mails und rechts eine Ansicht ohne alle E-Mails und nur einzelne Nachrichten, wie Neue Nachrichten verfassen, Nachrichten suchen,Filter für Nachrichten verwalten usw. Manchmal kommt aber die richtige klassische Ansicht zurück, wie jetzt gerade, später ist diese Ansicht wieder weg für längere Zeit. Ein Benutzer hat mir schon geantwortet. Ich habe alles ausgeführt, wie bei Ansicht Haken vor Konten/Ordnerliste. Das Problem besteht aber weiterhin. Ganz oben am Rand stehen bei Suchen die zwei Kästchen - STRG + K, die gehen aber nicht weg. Ich vermute, daß ich irgendwie eine falsche Tast angeklickt habe so daß die richtige Ansicht gehemmt wird. Es isr wahrscheinlich ganz was einfaches, ich weiß aber nicht wie und was tun. Hilfe wäre gut.

I have my operating system, and Thunderbird, set to the America/Vancouver time zone. When Pacific Daylight Time fell back to Pacific Standard Time on 1 November 2026, changing from UTC-7 to UTC-8 hours, our time zone remained unchanged at UTC-7 hours.

Now I observe that the Date column of Thunderbird's Message List display shows the date and time of each message converted into UTC-8. But the message date as displayed in the right part of the header in the message pane is displayed in UTC-7.

For instance, a message with the header `Date: Wed, 04 Nov 2026 09:27:27 +0000` shows in the Date column as "01:27" (today, 4 Nov), but the message date in the right part of the message pane reads "02:27".

I cannot find a control or documentation which governs the time zone used by either the Date column or the message date in the right part of the message pane.

How can I set to time zone used in the Date column of the Message List to use the America/Vancouver (or UTC-7) time zone of my operating system and of the Thunderbird calendar?

Hi I am at my wits end here - The date in my Thunderbird is behind by 1 hour. This is affecting sent messages and also received messages.

This just started today. For over a year, the time has been correct. I have not changed any settings in Thunderbird prior to this issue.

My Win11 computer shows the date and time correctly.

I had a Win11 update yesterday. Not sure if that has affected Thunderbird (My province - Manitoba Canada - also stopped using daylight time changes in the last couple of months.) We are now permanently CDT, and is UTC/GMT -5 - which is what it shows in my Win11 setting.

My timezone and time in Win11 settings shows correctly.

Just to see if it would make a difference - In Win11 settings->Time & Language - I changed the time zone automatic to off (even tho the time zone showed correctly) and set it manually to UTC-5:00 Manitoba, - I changed 'Set Time automatically' to off, set the time manually and synced the time.

No difference with Thunderbird.

Why is my time off in Thunderbird?, and what can I do or check to fix this?

I'm having problems with my default email account in thunderbird which might have started with the 28/10 update. Most times when I open TB the default account has no folders (inbox, spam, etc). To get them to appear I have to restart it. At other times it has all the folders present and all expanded including archives. When I can access my inbox the sort order is always by date descending so the oldest email is at the top which I don't want. If I click it to set it to ascending order it sets back to descending the next time I open TB. I've tried repairing the inbox but it makes no difference.

This just started yesterday: When I open thunderbird my inbox does not show up unless there is a new unread email in it. Also my previously set display columns and tool bar all have to be reset each time I open Thunderbird.

I've used Thunderbird on a pc for decades, love it. Today when I opened it, the 'top level' of folders is entirely missing, it shows only Local folders. I've checked that 'Folder Modes' is set to All Folders, and now I don't know what else to try. Any advice greatly welcomed, I'm struggling to get work done using webmail or phone!

Is there a way to pin an email to the top like Outlook? also, I would love to be able to create a unique signature like Outlook. Is that possible too? I tried to just copy and paste and it came out much like this. Crappy.

Thanks!

Wenn ich im Terminkalender einen Termin neu eintrage oder bearbeite erschnt ein Bearbeitungsfenster. Darin sind alle Eintragungen weiß auf schwarzem Hintergrund (OK).

Nur im Teilbereich "Beschreibung" erscheint seit einigen Wochen der Text schwarz auf schwarzem Hintergrund und ist daher nicht lesbar. Erst wenn dieser Text markiert wird, erscheint er gut lesbar weiß auf blauem Hintergrund.

Wie kann ich die Schriftfarbe hier wieder zu weiß auf schwarzem Hintergrund ändern?

Either Thunderbird filter function is extremely buggy, or there is something that I don't understand ... Some filters work pretty fine (though not always reliable) for years, an then suddenly they stop working. E.g. I have a filter (see screen shot) that's supposed to move all eMails with senders that are not in one of my Cardbooks to a special folder (Prüfen) and tag them.

This filter worked for many years - well let's say fairly. About 50% of the Mails that applied to the filter rules were marked and moves correctly, 50% wasn't. And about 10% of the Mails marked and moved didn't meet the rules ... Seemed to be some timeout problem, because when applied manually it did what it should.

Since the last update the filter doesn't work at all, when new messages are downloaded. If I apply the filter manually it marks all Mails, regardless of the rules - and it doesn't move any of them ....

It's a rat race ... I already thought of deleting all filters in Thunderbird and do all the filtering on the Mail-Server. But unfortunately the filter functions of my provider are rather limited. Now I'm wondering: Should I change my Provider, or rather my eMail-Client or both of them? It's really frustrating ...

Over the past couple of days, I've discovered new mail in my inbox but the new mail icon (with the red dot) doesn't show in the system tray.

I get notifications of new mail, which is fine if I'm sitting at the computer. But the icon in my system tray doesn't change, so I never know if mail has arrived while I was away.

I've tried everything - both in Thunderbird settings and Windows system tray settings - and nothing is making a difference.

Is this happening to anyone else? Might it be a bug?

When upgraded to 159, I seem to have lost the icon change in the tray that there is new mail. Still get the Windows push notification, yet that does not suffice with the volume of mail we receive. Any suggestions?
