Thunderbird Community Forum

Thunderbird just updated and the next time I opened it all of the folders I created and the emails I'm storing within them are missing. I found my profile as directed. I'm not sure if I have a backup of it. I've included the screenshot as you ask for. I know that those folders and emails are there as I was playing around with the the 3 lines > View and when I moved between the different choices I saw my folders/emails are all in there.

Any assistance you can provide is appreciated!

Since some time my standard number of print copies in Thunderbird has changed from 1 into 2. I have to adapt this number each time I print. How can I change this back?

I have been using Thunderbird since over 7years, facing issue since few days. Have my personal mail linked to my website hosted on a unix server. All sent mails were earlier visible in Sent folder. But now since a week only yesterday's mails are visible. All previous mails are in a subfolder by year 2026 in Archive. This makes it difficult to search sent emails. While this is not an issue for the Inbox where I can see emails from 2017. Please suggest how can I restore all my previously sent emails since always, to my Sent folder.

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!

This is more of a suggestion than a question.

I have been enjoying Thunderbird's Email account immensely, however there is one area of the interface that drives me a bit batty.

I really like using the Unified inbox, so that I can see all of the new emails from all of the accounts connected to the interface. However, I would love to see some kind of change to the interface that would reduce the duplicate notifications I get when new messages get downloaded.

When a new message comes in I get multiple notifications for it, one in the unified inbox and one in the local folders (two notifs for the same message). Additionally if I delete a new email without opening it I get notifications for trash and even spam (I really have no desire to see those ever again, they were deleted or put in spam for reasons). As you can imagine if this happens with the three or four accounts attached (especially after a few days without opening it), it can get overwhelming trying to sort how many new emails I REALLY have.

If there was a way to modify the code involved to only report the unified (or individual) inbox rather than it and the local folders and trash and spam, it would be even better than it already is.

Thank you for your time! I hope this is a suggestion that can be integrated in upcoming updates.

Sincerely, DDRandall

As in the subject, my computer has sound everywhere else but, despite 'play a sound' still showing as ticked in general settings, no sound happens when an e-mail arrives. And, in general settings for 'when a new message' arrives, I can hit the Play Button there and the sound happens. How do I fix this?

I have over a hundred message rules which I have listed in alphabetical order. However, every time I add a new rule, it is a chore to alphabetically place it in with the existing list of rules. Is there a current way to have the list automatically be put/kept in alphabetical order? If not, perhaps including a method to do so in a future update? Thank you.

All of a sudden my emails are permanently staying in bold in my folders, in Settings >Reading & Display Ive tried changing the 'Automatically mark messages as read radio buttons and quit etc and the same issue is happening, please advise

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?

I tried the Toolbar fixes in this forum and got the menu to show up, thank you. (Any menu in Compose mode had disappeared. Actually, both Firefox and Thunderbird icons on desktop and Taskbar had disappeared as well, and I had to reinstate shortcuts. This may or may not be pertinent.)

But when I try to add "Send" to the menu, using customize, the "Send" icon is nowhere to be found as an option, so I cannot add it to the Toolbar in Composition mode. "Send" is grayed out in all bold textmenus. If I use Ctrl-Enter, message does get sent. Using Windows 10, still. Perhaps this is an upgrade issue?

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.

Hi,

I used to scroll up in current message using Shift+Space, but it stopped working for a few days now. it's not mentionned in moving around TB, so I don't know if it was normal behaviour or a feature added by TB's arch maintainer.

So thunderbird mail has this system where old emails spread horizontally across the top of the screen in small icons and if you select and open an older email from the sidebar for the inbox and then want to return to the inbox, the only way I have found to return to the inbox is to click and hold the left arrow on that horizontal bar at the top with the email icons. This is too time consuming. Is there a faster way? Also, is that bar necessary? Why not just have a system that uses the sidebar that actually identifies the individual emails.

Windows 11 Pro 64bit. I actually want to customise the tool bar - right click on that, you get 'Customise Menu", which does nothing. All I'm trying to do is recover the layout I had before this update. Calendar is missing for example.

Hi folks, I'm a happy Thunderbird user since more than 20 years.

I just updated my TB to Version V.153.0.1esr.

Then I want to compose an eMail and suddenly I recognized the two Menus with File, Edit, View and Send.... Attach are gone.

Normally from the top to the buttom I see the following menu lines: 1. Write: (no subject).... 2. File Edit View... 3. Send........ and Attach at the end 4. From.. 5. To... 6. Subject 7. The line with Paragraph etc. 8. The area to put my email text in

The lines 2. and 3. are fully gone.

Can you please give an answer how to reactive the lines 2. und 3. during composing an eMail?
