All of a sudden today when I click onm add theme to Thunderbird I don't get the usual dialog. I am told the the site wants to install a theme and I am only presented with 'Learn more' and 'Cancel.'

Any ideas why? James

Hello helpful community, Yesterday after first updating my mac ios, I updated Thunderbird (as directed) on my macbook pro and discovered that my local folders are gone. I now have version 128.7.0esr. I have read other conversations here about this problem but they are WAY over my head, and seem to do with PCs. Can you help me restore my local folders with instructions I can hopefully understand? Thank you!

My thunderbird taskbar icon just started to display arabic numberals instead of roman numerals for the count of unread mail. It's weird because it doesn't always display the arabic when hovering over the taskbar, but it has done it more often than not the past few days.

My Thunderbird Icon disappeared So I can not get into Thunderbird to update However the app is still installed but I can't approach it How can I update on this basis?

I followed the article "Switch from POP to IMAP account" successfully. But I am left with two problems: 1. Whenever I try to send an email I get the error message "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.lcn.com timed out. Try again." I have to use webmail or my mobile phone to do so. 2. After I switched, Thunderbird created a new folder for incoming emails with the title of my email address. I already had a default folder using my account name, so I copied all the new emails to that and deleted the new one. I then went to Server Settings and changed the User Name to my Account name, which it was previously. However, my incoming emails now do not appear at all, I can only see them on my phone or webmail. I have checked my settings over & over but I cannot see anything wrong. I would include some screenshots but the print screen button on this temporary keyboard doesn't seem to work properly. (I am in the process of transferring all my work to a new PC running Windows 11.)

How can I reroute incoming emails from certain addresses to new folders I've created in my account specifically set up for these emails?

Since Sunday March2 10pm I cannot receive any emails with thunderbird. timout occurs on all my email accounts as there are imap.web.de, outlook.office365.com, imap.vodafonemail.de.

When I use webmail, I can see the emails.

Internet connection ist okay.

I have an iPad and iPhone and was having trouble getting my email. I inadvertently deleted by Thunderbird account. l'm not very literate with technology and would like help. I believe the program is still on my laptop, but I can't receive or send email.

Hello

Overnight Thunderbird has developed a major problem. The count for the number of mails in a folder is correct, as best I can tell, but when I open the folder it is either empty or has fewer mails than the count. Based on several tests, repairing sometimes adds more mails, sometimes not, but never the entire folder.

I repaired the inbox and it is now showing several mails that I deleted in the last few days (by emptying the delete folder having previously deleted them). Curiously, they’re all the same type, routine mailings about road works.

I may have backup in that I copy the entire Thunderbird folder to an external drive every morning, including today, and to Google Drive every Wednesday.

Please can you help.

Thank you

I have two calendars on my iPhone, in the Calendars app. I maintain the same two calendars in TB. TB is set to "Show all calendars", and it does show them. If I make an entry in either of the calendars, it DOES automatically sync and show up on my iPhone. But if I make an entry on my iPhone, it will only show up in TB if it is entered into the "My Calendar", but it won't sync if it was entered in the second calendar, even though both of the calendars are active and show on the iPhone. Help!

Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

I work with numerous filtres and so far it has worked with no problems at all. From today though the filtres do not work properly anymore. Today when I filtred the sent folder it sent all sent messages to the spam folder instead of e.g. customer folders. Is it an update that has gone wrong? I've checked my filter for spam and that is set correctly for subjects, or senders etc. What can I do to sort out the wrong filtering? Thank you in advance for your help :)

I often have open email tabs and come back to them days/weeks later to go through them. Today I was deleting emails not needed to free up some space, restarted the computer, and all my open tabs are blank, both the heading on the tab as well as the tab itself. I have no way to know what those emails were, except to go through a couple months of emails, looking for ones I had open. Any idea how to restore the text in the blank email tabs?

Hello thunderbird support team, Maybe someone can direct me to how fix an issue to create backup my emails and only have my inbox and sent email of this year. (2025) I don't know if I am doing something wrong or is this a thunderbird bug report?

I am using AOL, as my email provider. Goal is the create a folder of each year with all the emails received and sent that year into an archive folder. How I preform this task. 1. I create folders with thunderbird, these folders are then pushed into my AOL email account called archive folders. (works fine) 2. I move (highlight and drag) my inbox emails into a folder by a year, which removes them from my inbox, and this puts a copy of each email into the archive folder that I dragged them too. (works fine) 3. I do the same function (highlight and drag) my sent emails as I did in step 2 above. (deletes all the emails, that were in that folder that were inbox emails (received emails) that I wanted to save.

Here is the question. Why would moving my sent emails to the same archive folder, delete my saved INBOX EMAILS in that were in the archive folder? I lose completely and can't find them, not in trash, only the Sent emails are left in the file after 3 above is performed.

I would have thought that both the inbox (received emails) and sent emails would coexist in the same file! With maybe the sent arrow to identify the sent emails from the inbox emails. I tested this a few times with small batches of emails and each time I lost the inbox email in the Archive folder.

When I created the Archive subfolder for 2023 Sent year see below, (photo) to store my sent emails, nothing we deleted in my 2023 Archived inbox saved emails. Conclusion: for some reason, both Received INBOX and SENT emails can not be combined in one Archive folder? Really? Regards Eric S

I've had this problem for a while on two computers, and through a few versions. I have also created a new profile on one (as the old profile was for some reason locking up every time I used it, and thankfully I use IMAP, so it was easy to recreate).

I have sub folders on my mail server (currently delivered by Exim and Dovecot for the IMAP folder structure) and when I expand the sub folders to select one I am unable to select the top one until I have selected another one. Clicking on it does nothing, but clicking on another and seeing the messages in there, then clicking on it shows the messages. This only happens with the top folder, so I'm wondering if the code is somehow classing that as already selected.

I thought I'd ask here before looking into raising a bug report.
