Hi,

I use Thunderbird 152.0.1 (64-Bit) and I only have three items in the files & attachment section of general settings (JPG, PDF, Excel). How can I add more items, for other file types? Is there an easy way to do this or does this mean I have to deep dive into the configuration of Thunderbird?

And would it be possible to add an item to declare that website links in e-mails have to be opened with Firefox in private mode, which is not the standard browser on my machine?

Thx!

Hello All, The opening email changed to a reader that works, but I'd prefer to use the "Classic Reader" by default. Searching the settings hasn't turned up anything that sounds right. Is there a behind-the-scenes file that I need to edit to resolve this issue?

I transferred data to a new computer. I have two emails, when I click 'New Message' one email has a line below the subject line that allows me to set Paragraph, Variable width, font color, Font size Bold, etc. the other does not have the line where do I turn it on at?

Hi,

I want to delete the amount of emails the Thunderbird stores on my local computer.

I do not want the email on the server deleted.

I went to settings, local folders, disk space and chose the option for Delete messages more than 30 days old.

I made the change and ran compact.

It's not deleting the emails at all.

Why not ?

Again, I do not want to delete the emails anywhere else (on the server), so making the change under the folder or my account is not it.

Anyone able to point me to where the problem is and why the emails are not being deleted from my local disk ?

I'm running Thunderbird Ver 152.0.1 with Windows 11. I have things set up so that I just need a single click to open a program, folder or file.

This also was the case until just recently with Thunderbird. I could open new messages with just a single click. For some reason this has changed to me needing to double click to open new messages.

I don't know why and cannot find any method of changing the software back to single click operation. It is only affecting Thunderbird all the Windows operations still operate with one click.

Can you advise me on how to reset the Thunderbird software to single click operation.

Many thanks. Alan Tierney

I am experiencing an issue where clicking links inside Thunderbird emails forces Microsoft Edge to launch a completely brand new window with a blank profile (no extensions, default settings). It does not open as a new tab in my active window.

My environment details:

• OS: Windows 11 (Version 25H2) • Default Browser: Microsoft Edge (Only one profile exists under edge://settings/profiles, no Workspaces used). • Thunderbird version: Latest stable release.

When Thunderbird passes the HTTP/HTTPS link to Windows, Edge seems to ignore the standard "Default" user data directory profile and launches a temporary or guest-like profile container instead.

Is this a known bug in how Thunderbird handles external URI handlers, or is it an Edge registry/default app assignment issue? Any help or workaround config settings would be appreciated. Thank you!

I already have View > Sort by > Date is selected, View > Sort by > Descending selected, and thread sorting set in settings. See screenshots. Threads sorting so newest is at the bottom, they should be at the top. General emails are sorting properly, newest at the top.

I’m looking for card body previews in the message list/card view, similar to seeing a short preview of the email body under the subject/sender. Is this feature currently available anywhere in Thunderbird?

If not, is it planned, and is there any estimated version or timeline for when it may be added?

Until recently, when I clicked on a link in Thunderbird, it was opened in Thunderbird. Now the link is opened on a wide-screen external monitor. I can't find the setting that was changed to make this difference.

Very little to do with accounts, but none of the selectable topics cover 'user Interface'.

Used to be able to open different accounts in different windows. Can't remember how, but it was obvious. Once new window is created, each time Thunderbird is started it re-creates them. I accidentally closed one and can find no way to re-open it. I use three email accounts each needing a different mindset, so keeping them in different windows helps. Also one has a screendepth full of folders and so is easier to handle in its own window. (The others are still there but only take up one line each when collapsed.

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

I recently upgraded to version 115.10.1 and it is driving me utterly insane. It repeatedly turns on threading. I turn it off for a folder, next time I log in it's on again. I turn it off in a folder and copy that setting to all other folders, but it turns itself on again. Others say turn it off in Settings/Appearance. But I don't seem to have Settings/Appearance.

How do I stop this? Or is there a way to find out what version I was originally running and go back to that. I hadn't upgraded for a good while but my old version was much better. This one is also really slow and I hate the tiny text.

On upgrade to 152.0, a pop-up asked for options I have not seen before. I cannot find info about what the net.thunderbird option is, nor why I would or would not want to click it? Any help out there?

Thanks!
