Thunderbird Community Forum

I can't seem to get Thunderbird on Linux Mint to work. Everything font related is a mess. I don't know what default Thunderbird uses when it doesn't know a font but the setting is unreadable. I've messed with a ton of font settings but nothing seems to change anything. Note if I copy the garbage and paste it into a notepad, it is totally readable but there appears to be no way to change this default in Thunderbird. Please help.

" attach the signature from a file instead "

I put the URL in there and it does not retain it and use it as signature image. It is a jpg. It browses in a URL on my browser and loads fine but T/B refuses to allow it.

Suggestions ?

had the need to start a fresh thunderbird profile.

now I forget which setting(s) allow for thunderbird to scan the local folders, NOT the internet, for new mail.

any suggestions?

thank you

In Thunderbird, the "Play a Sound" feature has quit. I changed from 'Use the following sound file' to 'Default system sound for new mail' and back again. That didn't work. I tried changing the file in 'Use the following sound file'. That didn't fix it. I restarted Thunderbird and it was the same. I don't want to uninstall and re-install. Is there a fix?

When I tried to import my OpenGPG keys from the "Select File to Import...", I found that it cannot display the hidden files or directories.

Did I miss a setting for this? What can I do to show the hidden files?

So I have a list of folders some of which are the default folders some are custom created.

When I try to re-order these it is very hit or miss: I select a folder, drag it to where I want it to go, wait for the blue placement line to appear and it may or may not re-locate. Or I simply can't move the folder I want to move and so I move folders around it in order to achieve the layout I want.

It is as if success depends on whether Thunderbird is in the mood for a particular move to happen and I find it really frustrating. It should or shouldn't work, it shouldn't be that it works sometimes.

What is going on with this?

I use Thunderbird 140.11.1esr with Ubuntu 24.04. I also use LibreOffice 26.2.

When using LibreOffice, if I want to delete a number of contiguous characters, I put the cursor at the start of the characters I want to delete, press the delete key and hold it. Holding down the delete key means that delete works its way through all the characters I want to delete.

When using Thunderbird, if I want to delete a number of emails, pressing down and holding the delete key doesn't result in the deletion of a number of emails. Instead, I have to keep pressing delete again and again.

Is there some setting in Thunderbird that I can change that will result in delete automatically working its way through all the emails I want to delete?

Thanks,

Leslie

I recieve several emails a day from a submission form on my website that contain what looks like Russian words. I would like to create a message filter to move these messages directy to the trash based on one or two characters that do not appear in the english language. I thought I had done it, but the filters don't appear to work.

I'm on Thunderbird version 140.9.0esr at present.

Machine: Dell Inspiron 15 Series laptop

Monitor: Viewsonic 27"

System: Ubuntu 24.04.4 LTS

RAM: 16 GB

For the last 2 versions of Thunderbird, I have seen that even after reading the new messages, the green new messages indicator remains on the TB icon in the taskbar.

Refer to screenshot.

It should of course disappear as soon as the new messages are all opened. Otherwise one thinks that there is an unread message somewhere among the mail folders, even though on checking there is not.

This remains so until TB is closed and re-opened. After re-opening the green circled number is gone.

Of course, this is more a nuisance than a serious problem.

But it would be nice to have it sorted by the next version.

please explain the explenation at https://support.mozilla.org/en-US/kb/appearance-panel-layout-message-list-card-view-tab#w_card-view

What 2 rows / 3 rows?

Hello,

I am using Thunderbird on my arm64 Linux machines (Raspberry Pi 4 and 5 and my Odroid C2) and I want Thunderbird to send the correct platform information in the User-Agent line. After enabling Thunderbird to sent the full User-Agent line the following information is currently sent:

User agent:Mozilla/5.0 (X11; Linux x86_64; rv:140.0) Gecko/20100101 Firefox/140.0 Thunderbird/140.9.0

Everything is correct except for 'x86_64'. I would like to have sent the actual 'arm64' information because I'm proud using my small ARM64 machines as workstations and as a replacement for classic PCs and I do want to have this information distributed with every mail I am sending with Thunderbird.

Is there an easy way to get the correct information about my arm64 machines into the User agent line?

I am happy for any advice and help.

Kind regards,

     Roland

- Linux ver 140.7.1esr (64 bit) my folders are now out of alphabetic order among other things Trash us now under 'T' instead of grouped near the sent folder and my Computer folder has a mind of it's own. It's not under C even after I changed the name. It is just stuck. Wha? tnx

Threading - why does it keep coming back? I have just realised it's back again on my Thunderbird and I never knowingly turned it back on.

Why does Mozilla keep trying to force it on users?

This has been an annoyance for users for several years now and the message has still not got through it would seem.

For an open and user-facing organisation, this is strange behaviour that I just do not comprehend. Include it if you want, but make it optional and easily so.

I know this is only the community forum, not Mozilla, but one would think that a wise organisation would keep an eye on what their customers were saying & feeling.

After installing thunderbird, It takes me hours to figure out that my fonts are too small because of one value in Settings > General > Language & Fonts > Fonts > Advanced > Fonts for Other writing systems gives a too small number.

It seems insane and I don't think users can easily get there. Maybe some users want to set different fonts for different languages and the "Fonts for ..." is for them. However, for most users who just want to change their font size, I don't think it's a good experience to going so deep and find an option in the loooong "Fonts for ..." list.

So please give users a simple option where I can just set my font size without such pain.

I know there's a font size option in TB menu but it doesn't work as expected. In my case, the font size shown in TB menu is 16 while the font size of my plain text emails is 12. And 1. email font sizes will change to TB menu size as long as TB menu font size is not 16. For example, when changing TB menu font size 15 -> 16 -> 17, email text just suddenly goes from 15 to as small as 12, and then from 12 to 17. 2. email font size seems changing with the TB menu font size. However, email text font size will go back to what it was when open another email.

Using a new, clean install of Xubuntu 26.04, with thunderbird 140.10.2esr 64 bit, ubuntu snap build 1.0. In settings: play a sound when new message arrives, no sound is heard. When clicking "play" to test the sound, there is no sound. Also, if "use the following sound file" is checked, there is no sound when "play" is clicked. (I have tried various .wav and .mp3 files.) I have installed pipewire-alsa, but that didn't help. Any ideas?
