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!

Sometimes an email I receive contains text whose right margin and text is chopped off. I thought this was because the emails were formatted for Google's gmail, but I just received an email from Thunderbird itself that is truncated this way. What's going on?

I'm enclosing a screen shot. I can also send the .eml file if that's helpful.

Na versão 153.0esr do Thunderbird, quando se clica na pasta com o botão direito do rato, o menu não apresenta a opção de adicionar pastas aos favoritos. Para além disso, quando se arrasta uma pasta para a área das Pastas favoritas do menu esquerdo, nada acontece.

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 have no desire to interact with Google, Bing, or Perplexity, and as a rule I don't want outside parties (such as Firefox/Mozilla) deciding for me which search engines or other service providers I see advertising for. (And yes, seeing that "G" logo somewhere is advertising for Google.) I'm assuming that these companies are paying to be pre-loaded as search providers in Firefox, and I understand that Firefox needs this financial support if it's going to continue providing a browser.

After upgrading, I've always gone into the settings and removed these search providers - I don't want to see them offered as search options, and to be honest, I don't even want to see their names in the settings screens.

Now with Firefox 152, I find that I'm not able to delete these pre-loaded search providers anymore. I can turn off a switch to disable them, but there's no way to totally delete them from the list anymore. There's even a [in the documentation] which explicitly says that the pre-loaded search providers cannot be removed, only hidden.

'WHY can I not delete them?

Is there a technical reason, i.e. would the browser stop working if they were removed? Are some companies paying extra to not be delete-able, and it just happens that every one that's pre-loaded in Firefox 152 decided to pay the extra money? Or did Mozilla just make an arbitrary decision to reduce the level of control that users have over their own browsers?

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??!

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 been using Thunderbird since over 7years on pop. I am facing issue since few days. I Have my personal mail linked to my website hosted on a unix server. I use thunderbird mails latest version. 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.

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?

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.

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?
