Hello! It seems Thunderbird emails are suddenly being 'threaded'. It is causing great confusion in my office.

I need to see each email from a person separately in order to find them easily and also to reply to each one at the time it is received.

Can someone please explain in very simple non-techy jargon:- a) How I 'unthread' messages already threaded AND b) How I stop any new ones being threaded in the first place.

Thank you Tylex

Now in v 150, I can no longer modify the tools in the reading pane. Used to be able to but it seems to have disappeared. Of course layout is modifiable but spacing out the tools (so that I don't hit the wrong button in error) or turning some off is no longer an option. The More|Customize does not do much for what I want. Thoughts?

I’d like to request a feature for Mozilla Thunderbird on Ubuntu/Linux:

A native system tray (AppIndicator) integration with the ability to: • Run in the background without keeping a window open • Minimize to tray instead of the taskbar/dock • Option to start minimized to tray on system startup • Show unread mail count directly in the tray icon

Right now, users rely on third-party tools like Birdtray, which work but feel like a workaround rather than a seamless experience. A built-in solution would improve usability significantly especially for those who prefer a clean desktop while keeping Thunderbird always running in the background. I think this feature would bring Thunderbird closer to the behavior users expect from modern messaging/email clients on Linux desktops. Would love to see this considered in future updates!

I have split viewing pane, but the preview on the right has an overlap so I can't see / preview the email. I have tried all "layout" choices but still can't get that line to go away so I can view who it is from AND the message. I have tried everything I know but that line remains.

My email messages format has changed. Used to be a very readable format now it has changed to a bunch of links with small wording. Example - an email from Swansons: [Swansons](https://www.swansonvitamins.com/)

This is an inch and foot indicator: " and ' This is quotation marks and an apostrophe: “ ” and ’

I want my emails to be grammatically correct and currently everything uses the inch and foot indicators instead of quotation marks and apostrophes.

Thanks, Janice

How do I reinstate notification of number of new emails in my taskbar icon? It has suddenly stopped showing this. I found the same question in 2023 but I don't understand the answer.

I have created several categories that I use to assign a color to each of my calendar event entries. When I do this, the event shows a very thing stripe of my assigned category color down the righthand side of the entry. I would REALLY like the entries to be colored entirely with my category colors rather than that tiny stipe. Is this feature available and if not, I am hoping it can be considered in the very near future.

Using Thunderbird version 140.8.0esr on Windows 10 . Been trying to reorganize local folders. Thunderbird is NOT correctly alphabetizing local folders. I've beaten myself to death googling for answers, and nearly every entry claims you can right click on the account name and select "Reset Folder Order" and it will take care of it.

there IS no such option! Anywhere!

Other answers claim you can drag the folders manually into the correct order. Not happening!

There must be a real answer to this issue. Where do I find it? And please don't advise upgrading to Windows 11 - this CPU/motherboard won't support 11.

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.

Hi,

I am trying to edit my message separator line (which I added many years ago). Now there is a big gap in the line and messages. How can I reduce this gap please? Any advice?

Regards,

LS

When I reinstalled Thunderbird recently, it no longer leaves messages in my inbox bold, the darker font indicating unread until I click on the message. I tried changing the settings, but it doesn't seem to "take". This is annoying because it appears as if I've looked at all emails in my inbox just because Thunderbird is open. I'm not looking at it, I come back, nothing is in bold. It makes it harder to id spam, because at a glance I think everything is OK email I've already looked at.

Most of my buttons have disappeared except the send button, which doesn't work. Online help is confusing or doesn't fix the problem. I'm ready to move to a different platform. Why is this so difficult?

Good afternoon! I have always had a specific folder order in my email, with the inbox folder being the first, followed by the sent folder, and so on. However, today I discovered that the inbox folder was at the bottom of the list, while the sent, spam, deleted, and other folders were above it. I was unable to change the folder order back to its original state, and I have been unable to drag and drop or swap the folders. Can you please advise me on how I can restore the folder order to its original state, with the inbox folder at the top and the other folders below it?
