I was attempting to import the calendar info from my old system to my new one, but the export/import of a .ics file did not work. It complained about information not being found. Then I tried copying the local.sqlite database file from my old system to the new one, that initially did not appear to work either :( Come to find out that the database cal_id fields did not match between my new system and the old one, so even though the local.sqlite file I copied had all of the calendar information, the prefs.js file on my new system was referring to a different cal_id. So I used a text editor to replace all of the cal_id's in the prefs.js file, with the cal_id found in the copied local.sqlite file, and now I have all of my calendar data available on my new system. You might want to make this know to your users, since my original searches on your support site did not present a solution that worked. :(

I've downloaded Thunderbird in office PC and on PC at home. Almost I working in office PC or web mail but when I open Thunderbird at home, all my email lost in web mail and it's happened for such times. Is it a setting problem?! or, if it will be happen if using Android version ?! Thank you for your kindly assist!

I just had to reinstall Thunderbird on my computer. Somehow after being away for a year and firing up my computer Thunderbird advised best to reinstall. I was able to get some of my contacts but not all. Thought it would be simple to just export my Thunderbird address files from my Windows laptop and import it to my Thunderbird app on my windows computer. Seems obvious and simple but not so for me. The suggested solutions do not work. Am I missing something?

Using Thunderbird for my mail. ATT Yahoo is my provided. My ATT password is not allowing me to get my mail. I keep getting a message to re enter my password. Password does allow me to sign in to my att account.

I have been using Thunderbird for 20+ years, maybe as many as 30. Forever. I have moved my profile across several versions of Windows and multiple computers. There are files in the root of the profile with a modified date of 2009. There may be older ones in sub-directories. There are 18 folders and 125 files. I suspect a lot of this is clutter left over from earlier versions of Thunderbird. In the Mail folder alone there are several hundred files and folders excluding the WDSEML files and actual emails.

I'm toying with the idea of starting fresh with a clean install of Thunderbird and getting on the correct release channel but I don't want to bring along what appear to be hundreds or thousands of unused files and folders.

I there anyone that can identify what profile files and folders to keep and what can be deleted?

Thanks for your consideration.

The Windows 10 PC crashed after an update, but I have command line access. I copied the profile folder from the Thunderbird installation to a USB drive, but can't find a way to move the subfolders (like 'name' and 'name.msf') to an existing installation on the new PC.

Is there a way to import these into the new installation?

I'm using Thunderbird 152.0a1 (2026-04-22) on Windows 10 64 bit. When I click the "Get Messages" button or File > Get New Messages for > [my e-mail account] nothing happens. The only way I've found to check for messages manually is by closing and re-opening the program.

Today, I have received an email, claiming to be from Mozilla support.

The text is garbled but it appears to contain words, 'hacking', 'paynalti', and 'auto-block'. These are words which immediately put me on security alert. I haven't opened the mail but have viewed it in preview pane. and screen grabbed the attached pdf image.

Any comments?

Thanks, William

Lorsque j'essaie d'ajouter un nouveau compte, la configuration est trouvé dans la base de données des FAI de Mozilla, je clic sur "continuer", dans la fenêtre Popup j'autorise Thunderbird a accéder à mes informations, ensuite j'ai le message "erreur d'authentification". Pourtant mon mot de passe est correcte.

What I want to do is to is export just the headers of emails on IMAP folders with an Excel VBA macro so that I can write filters to import into Thunderbird for deletion of old new letters and things of that nature, keeping only the important emails.

Knowing the message filter file format would also be nice considering that I can then just mass edit the filters without needing to recreate them each pass.

After downloading and running installer (Thunderbird setup 148.0) from Thunderbird website, Thunderbird opened as usual, showing my three email accounts. The 2 accounts I use for almost everything are both Yahoo accounts (yahoo.co.uk and rocketmail.com). But.. neither of these accounts will work without a yahoo sign-in pop which is pre-filled with an account name (example graphic attachment : thunderbird01red.jpg). 1 example shown but the same thing happens for both yahoo accounts.

The 'Next' button, which I assume will ask for password, does nothing.

I have attempted login via webmail. I enter account name, am asked for password and Yahoo insists on sending me a verification code - to the other yahoo account (the yahoo.co.uk account), which I cannot access! I then attempt to login to the other account to access my pass code and the same thing happens in reverse, telling me that a verification code will be sent to the first account.

Via Thunderbird, which has for years done all this automatically behind the scenes, I can get absolutely nowhere. Via webmail, I am in an 'impossibility loop'. I have cleared cache for each account.

Why won't Thunderbird allow automatic account login, as has been the case since the year dot. These are the 2 accounts around which my entire life is ordered - can somebody please help.

I set up a new account last week and need instructions on how to navigate and use this forum. I cannot find the question I posted. I got no email saying it was answered. I also need information about these codes I keep getting in my inbox after I've already logged in. I don't know what to do with them. I'm a newbie and need an instruction pdf if there is one. Thanks.
