The red background of selections and default buttons makes it almost impossible for me to read the black text. I'm using Thunderbird 1.28.1esr on a fully updated Windows 10 desktop machine. I tried deselecting the use of System colors with Thunderbird Settings/General/Fonts & Colors/Colors, with no effect. How can I change the background to my Windows system background of gray or any other background color that can Thunderbird selections readable?

Running TB 128.14.0esr on Linux Mint MATE. In the Create new message (Write) window, I want to change the background colour of the panel that contains From, To, and Subject. This is currently a light grey. What userChrome code can I use to change the colour? Thanks

I have recently lost all my filters after a conversion to IMAP. To quickly generate many new filters, I wish to have a quick shortcut, perhaps a key-combination, that will do the following:

For the message that is currently highlighted and for which the shortcut is invoked:

Create a filter that will Match on From > Contains > the domain name in the URL

and that will Move the message to Local Folders > Trash

Is there such a way to do this?

Thank you

Hello people,

When I compose a message in my word programme (Softmaker or Libre), save it in Docx format and copy/paste it into Thunderbird to send it everything is double spaced and nothing I do in the "compose" menu can change that.

I have tried it with "Use Paragraph Format" checked and unchecked and it stays doule spaced and nothing I can find in previous threads seems to address this problem.

What am I missing?

I've imported/exported everything I could from a Win10 to a Win11 one. I then went to the toolbars under "view" and made sure they were all checked. Next, I clicked on "customize" and selected (single click) what I wanted to add to my toolbars in the mail window. The "save option" was greyed out. How do I save these to my toolbars?

I have uploaded an image of my view of the email client. As you can see, there are two columns under the red arrows. I have made them appear through a menu accessible by three dots. Somehow, I have lost that menu but touching the wrong choice and I would like to be able to access it again so that I can remove the two colums indicating the number of emails and their weight. Can you help me to retrieve that menu?

I want to send messages I delete to a Trash folder on my laptop, rather than the Trash folder on the server. Is there some way to do this? I'm looking at:

Server Settings > Security Settings > When I delete a message

This only gives me the option save deleted messages somewhere on the server.

(I have given up all hope of convincing Thunderbird to download all my messages, but fixing the Trash problem will make the program at least useable, from my POV!)

When using Thunderbird 140 I am able to setup the background color of the message pane for individual messages. However when the messages are threaded, the message pane shows a preview of all of the threaded messages together in the message pane with a different background color than individual messages.

I work with filtres on my pc and now I have also downloaded Thunderbird to my android phone. How do I get filtres and labels to work on the phone? Thank you in advance once more for helping out, Mette

Thunderbird did not work last summer so I switched to Daily working similar and fine. One day forwarded messages started to contain a huge list of mail-data (Authentication-Results, DKIM-Signature,..) instead of just time, date, topic, adress. How can I get rid of this? Thank you

I've been using Thunderbird for about two months now and I just realized that Thunderbird (150.0.1) seems to be unable (or unwilling) to use some of the fonts that are on the computer (Windows 10, plenty of RAM and disk space).

Let me explain that I don't send a lot of emails, and most of the ones I do send are just a few lines so I had not had any reason to bother with the font -- the default font was fine -- until today...

Today my experience with fonts in Thunderbird was extremely disappointing. It started when I was composing an email and I copied/pasted some text from a web page into the email. Rather than treating the pasted text as simply text to have in the default font, Thunderbird put it in some strange font and size. This might have been Thunderbird's attempt to use the font from the website but neither the font nor the size resembled the text that I had copied/pasted. That was when I noticed that Thunderbird does not let you choose the actual size but only offers the choice to make text larger or smaller. Making the text smaller was sufficient for that particular time.

As I finished the email, I tried to sign my usual signature. Thunderbird lets you choose the font but once I had chosen the font that I routinely use for my signature, I discovered that Thunderbird totally ignores the choice that it just let you make. Instead of displaying the signature in the chosen font, it displayed my signature in a plain sanserif font.

I could live with a limited choice of fonts -- I have used another program where the only choices were serif and sanserif -- but I cannot understand why Thunderbird would offer a font choice menu that includes all my installed fonts when it actually only honors three choices. The only fonts reliably used seem to be some generic sanserif font that Tunderbird calls Helvetica/Ariel, a generic serif font that it calls Times and another serif font it calls Courier.

The dropdown menu lets me choose any of the fonts I have installed, some of them display properly while composing the email, others don't. If I send the email to another of my email addresses, Thunderbird displays the text the same way -- some fonts are correct and some fonts get replaced with one of Thunderbird's generic fonts.

I'd really like to have all my fonts available -- but that doesn't seem to be possible with Thunderbird so I guess I need to figure out which fonts Thunderbird is willing to use.

My e-mails are sorted from earliest (top) to the latest (bottom). Suddenly about 15 messages have gone out of order. Early ones have appeared towards the bottom (later ones, have appeared under those). Is there an easy way of moving them so they are all sequential?

Thanks

Emails received in reply seem to couple themselves under the original sent email. How do I tell Thunderbird to treat them as separate, and stored them in my inbox as a separate individual email. Thank for your advice. Kanga85

Hi. Right now mesages with same subject are shown under first message (Uploaded image), this is good, but I would like to see them like messages in gmail. If I open any message I would see all this messages in message pane as list. Where I could make some compact or if I want I could expand all messages and see them all at once. Is this posible in Thunderird?
