Thunderbird Support Forum

Hello, i try to customise the thunderbird mail colors, but can't find any settings to that. I want to change the colors for "marked as -> unread" messages and the color for new received messages. Can anyone tell me how to adjust this? I tried to add the "userChrome.css" file in the self created folder "chrome" in my profile directory, but nothing changed. Can someone help me? I use Ubuntu 22.04.4 LTS version and the thunderbird version 115.6.0.

Intro : I find the glaring background is hard on my eyes and the black/dark background seems not right. Trying to soften background with a lighter shades rather than glaring white. I am no IT person but like to dabble on a spare PC to try and get it right.

I have tried applying this method https://support.mozilla.org/en-US/questions/1418832 with no change or noticeable damage. Feel as so though its close I have mixed it up a bit with the 2 examples given with half a dozen of my thoughts to no avail. Here is my last .CSS file attempt . See below

I realise I don’t understand all of this and I could go learn all about .CSS Files. I also realise I could spend any amount of time learning it. To not use in the next couple of years and I have forgotten or it has changed again. So please if someone could help me out here. I thank you in advance and appreciate the contributors here for their post that I have used in the past.

Regards George

Having threads is not very helpful with unread items within that thread. I don't think the developers thought this through. If any one email in a thread was not read it should show the the thread in bold just as emails. Is this a bug or a feature? How can I change that?

Hi,

I have got latest Thunderbird installed with Mail Merge Version 10.4.0 on a Mac. When I try to send a mailmerged email from a CSV (Used automatic or comma separated setting), it throws an error saying "Unsupported Zip file" and gives me links to the Home Page and the Change Log file.

When I accept the error message, it allows me to go into the final mail sending window. However, when clicked the "Start" button, no mail is sent.

Mail merge works without any issue on Windows PC. The issue is with the MAC.

Any help in getting this issue sorted is much appreciated.

I have TB 115.6.0 running on 3 computers (1 desktop and 2 laptops). On 2 computers there is a tiny icon on the right hand side in the menu bar that allows me to switch between the "new and improved" (but utterly horrible), side by side message list and the classic view.

On the laptop I am currently using to write this request, TB 115.6.0 does not have that wonderful little icon and I am condemned to use the side by side display or find another mail client.

Can someone help me find or restore that little icon that gives me a choice or alternatively lets me change the message list display back to its old useful configuration?

As an aside, why do software developers insist on making "improvements" that no one needs or wants?

I cannot change the layout in TB 115.3.1 as my layout options under the view menu are locked. How do I unlock the view options to change from vertical layout to horizontal layout?

Hello There all So I recently installed Win11 and Tbird 115.7.0

My issue is this: When I double click a PDF in a received email it opens up in my default PDF reader (Foxit) so it's all good. When I'm composing an email and add a PDF I like to check to see that I'm sending the correct PDF attachment so I double click and it won't open, I get this message (Attached Image) I went to Tools/Settings/General/Files&Attachments and PDF (Foxit) is set as the default so all good

So again Inbox messages opens PDF's no problem Composing messages won't open PDF's

I used to do this all the time on Win10 and it worked perfectly See my settings in image 2 Thanks In Advance :-)

i'm using thunderbird to read and post on usenet, it works, but i noticed that it is also sending out emails with every post i make, i see that in the settings for the newsgroup account the default outgoing smtp server is configured, and i can't remove it, is there a setting to not send emails when posting to usenet?

I have just installed Thunderbird v115.7.0 on Windows 11 for evaluation as a replacement for Outlook. After configuring my Gmail account, I was happy to find that it automatically synchronised with my Gmail address book and calendar.

The address book is nicely formatted and correctly displays all my data. When I attempted to copy a phone number, however, Thunderbird requested that I should link an application to the "tel file". I wished to link to Microsoft Phone Link but could not find a way to do this. As an alternative, I linked it to Notepad, hoping that I could then copy and paste the number. The was unsuccessful. Notepad opens but displays an error message: "Cannot find the C:\Program Files\Monzilla Thunderbird\tel.txt file".

Which applications does the link support and how can I change the configuration? I would be content if I could simply copy the nymber.

Hi, For some strange reason I can no longer see the total number of messages in a folder at the most bottom line. is there a simple way of getting it back please?

Thanks for the help. (Probably nth time asked/ answered...In order to avoid a repeat answer, I googled the problem, but similar questions were rather old (2017 etc) and they didn't help. Thank you

I like to read my messages from old to new. So when I delete a message, I want the next most recent one to be highlighted, not the next oldest one. At the moment, every time I delete a message, I have to then click on the message above the one it defaults to. It's a pain. Can I reverse the flow and make it move to the more recent message rather than the older one?

I am using TB 115 with a Relaxed density. Almost all the elements are fine for me, but the context menu space that is there is a too big. I would like to reduce it. How to do it via userChrome.css ?

I am afraid that I am not at all happy with the new version of Thunderbird. It may be that as I get used to it I will find some of the new features helpful, but right now I am more concerned about what was taken away that was helpful:

   a) I keep getting 'not responding' -- especially when trying to set my theme 'yet again (and again, and again)!!!!  I am mostly shut-in due to illness and the themes make a difference emotionally compared to a stark 'black and white'.  Furthermore, what is the point of having TB themes when they don't hold -- I often have to re-set mine several times a day

   b) tabs are now hidden -- I need to colour-code messages so I know which I need to get back to soon or can wait. Having them hidden under that new right arrow makes extra steps to do so

   c) the row of custom colours no longer hold: what is the point of being able set a row of custom colour if they don't hold!!!  I used different colours to indicate different responses in a thread -- thereby having an immediate way to see the order of responses.

   d) I need layers of sub-folders -- often to add a new name to a group I belong to, or a new year.  I have been asking again and again over several years for the ability to create a new sub-folder WHILE one is moving an email from the inbox to a folder or sub-folder.  Having to 'go' to the folder first, make a new sub-subfolder, return to the inbox, and then move the email is an unnecessary waste of time. 

   e) 'a picture says a thousand words' -- emojs are so useful in this way, especially when one is tired or can't think of the right words to say.  This feature was taken away years ago, and I wish that TB would bring it back.  The minimal 'yellow faces' are minimal useful.

   I am not techy enough to really understand what you have written below - what is a 'message context menu' and 'mock-ups'.  However, it seems to me that the TB functons (at least the ones that I need) are getting less and less useful and increasing 'cognitive burden'.

   Sorry to be so negative, but I do wonder who TB is trying to please/appease -- it is not this user.

   Blessings

I have messages in a local folder. Messages are assigned 1 of 3 tags based on certain criteria.

Is it possible to only view messages in the folder with one particular tag?

I tried looking at sorting, but sorting by tags is grayed out and not a sorting option. Im not sure why.

I'm running the latest version of Thunderbird. Thanks for any help you can provide.

New bug: When I select a message in my Inbox, it deselects (turns grey) in less than a second. To delete the message, say, I have to select it with the mouse and use the right-button menu. This is a pain, as I delete dozens of messages daily.

I have a saved query folder that I use to view the contents of three folders, each in their own IMAP account. When I select this folder, the queries don't run -- I have to go into each individual folder first to initiate another check before this folder populates.

Can someone explain how this works? Perhaps I need to subscribe to the IMAP folders to keep them actively checked/updated? I would expect that when I enter into the stored query that it would perform that query and those folders would be checked.

Thanks.

Recently I noticed the "sort by>order received" option has been disabled in Thunderbird (I am running version 115.3.3 64-bit). Other "sort by" options are still available for use but a few that appear on the list are greyed out and can't be selected.

Hi, I have a 115.6.1 (64-bit) version of Mozilla Thunderbird, and yet the device manager does not accept 64bit PKCS11 drivers (from C:\Windows\SysWOW64) for smart cards (tried several smart cards). It only accepts 32bit drivers. I have a smart card which does not have a 32bit PKCS11 driver.

Does anyone know why a 64bit version of thunderbird does not support 64bit PKCS11 drivers? Would any of the developers be able to address this please?

Thank you.
