Hi,

I have been using Thunderbird as my preferred email client since around 2004 on Linux, macOS and Windows.

I am current running Thunderbird 150.0.2 64-bit on macOS Tahoe 26.5 ( Intel ).

When I attempt to create a new 'Folder' or 'Sub Folder' on either an iMAP account or, more importantly, my 'Local Folder' the displayed dialogue box is sized incorrectly and I am unable to complete the action.

Specifically I can type into the 'Name' text box and see the 'Create as a subfolder of" drop down dialogue but the two buttons below are barely visible and I cannot select either with my mouse. Nor can I resize the dialogue box itself [ make larger ] to enable to be select either button.

I can use the <TAB> key to cycle thorough the various items and the <RETURN> key to select an option.

I have attached a sample image of the issue.

Thanks.

I'm using TB 150.0.2 on a Mac with the latest update of MacOS.

I just deleted all of my archived emails, thinking it was stuff that I had sent to trash. I.e. I deleted all archives, then emptied trash. Only after I did that did I realize that I had deleted things I want to save.

I'm pretty sure there's no way to undo emptying the trash, but I use Time Machine to back up. If I open time machine and go to the most recent back-up, I should be able to get everything back, right?

What folder (or folders) should I restore from a Time Machine back-up?

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

I'm on a new Windows 11 desktop with two monitors. Everything's been working just fine up until around 26th April (two weeks ago) when the native Thunderbird new mail notifications started appearing in my second monitor, rather than my main display. I had made no changes at all myself.

I've been through all the fixes suggested via Google (toggling the displays; checking Windows notification settings), but none of those fixes have made any difference. I switched to using Windows system notifications for a while, but I really don't like them.

Might this be something in a Thunderbird update itself? It just doesn't seem to be detecting the primary monitor at all. All my other app notifications continue to show on the primary display.

Has anyone else encountered this or have any other solutions I could try?

Thanks, Averill

I am unhappy with version 150 of Thunderbird. In earlier versions, I was able to access the full range of emojis when writing an email. That is no longer possible; I can now only access a few. The integration of add-ons with Thunderbird isn’t working properly. After adding the German dictionary, Thunderbird froze; after adding ImportExport Tools, Thunderbird not only crashed but also wouldn’t start up again.

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

I will preface this with no I do not have a backup - which is my fault. However I did not expect my account to be nuked into oblivion with no explanation.

As per the title, all my emails are gone. My local folders are devoid of anything I can use and am hoping that everything may be on a server somewhere. This is years of emails, important correspondence, bank information, business, etc. The ONLY thing I can think of is when I download the TB app for android and sync'd it using the QR on the desktop version of thunderbird. I then checked stuff the next day and everything was gone barring emails from that day, all folders, everything was gone. Is there no way to recover this?

When I open Thunderbird email on my computer, it loads in my emails. These come from my Hostgator email server. The date and time of the emails show as the current date and time, not the actual date and time that the emails were received on the Hostgator server. For example, if an email was actually received on Hostgator 3 days ago at 5 pm. When I open Thunderbird at 9 am today, the date and time received will show today at 9 am. And nothing that I can see on the email that I have on my computer shows the actual receipt date. I have tried some things on my own, and I have chatted with AI and made some changes to what's showing on the headers. But nothing has worked to resolve the issue.

I use Thunderbird to store loacally some email from gmail and delete it from the online server.

Until october last year it was working flawless, to day I need to read an old email and I discovered that locally since october of some email is only stored the subject and somtime I only have the ticker that increase in the stored email email, but there is either not title or subject. I didn't change any setting in my computer or in the antivirus,, the only thing is that I perform the update of thunderbird as usual. Is it possible to recover these emails or they are gone forever?

Best regards
