Thunderbird Support Forum

Question 1 - Is this a real version? (as dlsplayed in troubleshooting information) Question 2 - How can I upgrade to version 115,, or do I have to delete and start again? Sub question - if I have to delete what is the best method? I just spent a few days installing and then installing 5 gig of settings and mail from Windows 10; I would hate to do it again.

Tired of Apple mail, want to install Thunderbird 78.14.0 on my mac mini. Am running Yosemite 10.10.5.

I can see access to the files on this site but need an installer to load to system.

Am familiar with unix can work off a console but am not a programmer, wouldn't know one end of a compiler from the other.

Can you point me in the right direction?

i have an old win10 machine with a huge thunderbird profile - 37.9GB size / 75.2GB disk. i'd like to move it with Tools Export / Import to a new win11 machine.

on win10 i click thru tools > export > open profile folder

and in ...\thunderbird\profiles i select yhcc00j7.dan and export it to an external ssd.

it runs for hours and then a number of these appear: "Are you sure you want to copy with file without its properties? The file %2B...." has properties that can't be copied to the new location.... Type WDSEML file size 1.02KB....".

so i check "Do this for all current items" and hours later it finishes.

on win11 i click thru tools > import > import from another thunderbird profile > choose a profile and select the folder yhcc00j7.dan on the ssd and import everything > start

for a minute or so it says "importing .... 0%" but no new profile shows up in ...appdata\roaming\thunderbird\profiles\ and then "import failed unexpectedly" is displayed.

i've tried this twice. both machines have version 115.11.1 "esr update channel". what am i doing wrong?

I have created an entry in my Personal Address Book. When I am in that address book I click on the Import tab. I select CSV file. It provides me a File Dialog to select my CSV file. But then it provides me with a File Dialog to select an address book file. The address book I want to use is the one I am currently "in" in the program. But if I for some reason I wanted to import into another existing address book, I should either have to get "in" that one, or it Mozlla Thunderbird would list the address books it knows about as a selection.

It appears I am supposed to select the file that Mozilla Thunderbird created somewhere. From a search it appears (this is on Windows 11) from the App Store that is somewhere in ..\AppData\Local\MozillaThunder.MZL_h<numbers and letters>\LocalCache\<Roaming | Local>.

I don't understand why I am choosing a file that is already open in Mozilla Thunderbird?

TIA , Time to Migrate TB Portable to new computer : I was advised that all need to do is Copy this Folder C:\ThunderbirdPortable to new computer . But that doesn't bring over all my email accounts . Pls , what else do I need to do ? Thanks...

Hi all. I had a hard drive failure and managed to mostly clone the old drive to a shiny new one. There were errors logged during the clone and TB appears to be a victim of those errors.

Win 11 x64.

When I launch TB I get the icon on the taskbar but no main screen. If I hover over the icon I see a small box with the TB logo top left where you’d expect it, and Home next to it. Clicking it has no effect. TB appears to be functioning because new emails are being filtered according to the Rules, as witnessed on my phone.

I tried reinstalling 115.11.1 with no change. So obviously somethings fubar with my profile. What is the best way to proceed? Obviously I’d like to avoid having to set up all my email accounts plus the associated rules etc if it’s possible. I use IMAP if it’s relevant.

Thanks in advance, Tony

I have added my gmail account to TB and it downloads all the folders and emails correctly, but as soon as I try to move an email with an attachment from a local folder to a folder on the gmail acount I get "Connection to server imap.gmail.com timed out" errors.

Hello, I installed Thunderbird using POP3 to download all emails from my Zoho Mail server to store them in my PC but although all emails appear now to be in the inbox, there are no subfolders, emails are grouped according to subject titles and I cannot seem to find the latest email on the list. What can I do to display them chronologically by date and restore subfolders and archives? Upon lauching, this is what I get. Thank you

Win 10. Multiple email accounts, some gmail plus others. I had TB 115 something (it's uninstalled so not available to see). I run Firefox without issues. TB went completely haywire, all email accounts disappeared, nothing worked (second time this year) but recovering was proving too difficult and I'd already spent a whole day on it. I decided to uninstall and install a fresh copy. First I copied the single profile to an external drive. Then I uninstalled TB. Then I ran Ccleaner to tidy up the remaining TB cache and other remnants, also cleaned the registry. I downloaded a new copy from Mozilla's site, ran the install file, The install dialog box offers the same install location as the previous location, same user. Upon clicking install, the dialog box disappears and nothing happens. I've tried this more than ten times now, including fresh downloads from Mozilla. The dialog box offers an alternative user as Administrator but that won't work because I don't actually have the administrator account set up with a password, and TB demands the password. I do not want to open a new user account just for TB. Any suggestions for working round this will be gratefully received.

my windows 11 was crashed and browsing was not working so i repaired my window, thunderbird lost all profiles and data from the program but all the emails and folders names i had are visible in local directory, so i tried to setup new account and then change local directory to my old directory. i did this few times before and it worked perfectly but now this method is not working and only handful of emails imported i need help and solution, these are years of emails and very important last few weeks important emails are missing

A computer is still running Thunderbird 102 happily. That is the plan -- the user is NOT prepared to deal with 115 and later, and the changes therein. Somehow, even though it was supposedly set to only install updates when you told it to, it downloaded and began the process of installing 115. So it's up and running now at 102, but says that when you restart, it will go to 115. Please don't tell me how wonderful 115 is; been there, done that, it's not my machine but it's someone near and dear to me who detests computers in the first place but has to use them so gratuitous changes are utterly unwelcome....

So is there a way to delete something and tell Thunderbird to just keep running 102 and not do the upgrade? If I have to reinstall 102 on top of the old profile, which contains many gigabytes of IMPORTANT mail, I can deal with that. I assume that the profile hasn't been munged yet by the update so I'm asking now. Thanks!

I am posting this on my Mac Monterey; but the problem is on my Windows 10. It is similar to my last post about Firefox on that system. Updating is hanging. About Thunderbird shows an update available, just as that feature on Firefox did last week. However, though it indicates that it is attempting to download, it shows that nothing is downloading. So, there is a spinning icon on the left, but zero bytes downloading, just as Firefox did. After a restart last week Firefox applied the download. The same action occurs now with Thunderbird. To contrast, that same update just downloaded and applied on this Mac Monterey. The version on Windows 10 is 115.10.2, 64-Bit. There is a general Windows Update problem on that system. Edge, on the other hand, downloads its updates without any problem. I just ran a Troubleshooter that Windows makes available under Settings, Update and Security, Troubleshoot. Right now I am about to restart that computer.

Hi, David replied to my original question as to why the Folders are not loading off the Yahoo server onto a new computer as they are on my old computer.

The Thunderbird version on the OLD computer utilises a IMAP Mail Server. The version I downloaded yesterday and installed on this new computer utilises a POP Mail Server with no option I can see to change this. Screen Capture attached.

So Presumably I need the IMAP Mail Server version of the App. If I'm correct where would I download it from?

Thank you and kind regards, Mark.

hi there

i have been keeping my local folders stored on my microsoft sharepoint but need to move them to my local drive due to storage restraints on my sharepoint.

the first thing i did was to change local folder location to my C drive (I know how to do that).... then when I started looking online for how to move the local folders, I decided I should probably start by directing thunderbird back to the original local folder location on sharepoint... but now I can't seem to undo the change and whilst I can see my local folders on the sharepoint, i don't know which folder to select so that thunderbird will display my local folders correctly.

see attachment 1 - this is where I am directing thubderbird to find the local folders

but the local folders are looking like attachment 2

I'ved tried directing it lower down in the file hierarchy, or higher up, but nothing seems to work.

Can you help by telling me which folder I should select?

please and thank you!!!

I've recently decided to switch to Thunderbird from Windows Live Mail, which is no longer supported. I also use Mailwasher PRO which displays emails on the server and allows me to delete unwanted emails from the server. If I download emails to Thunderbird, I expect them to be stored automatically on my PC. However, when I subsequently delete them from the server, using Mailwasher, they are deleted from the inboxes in Thunderbird as well.

I'm guessing it's a setup issue but am struggling to find what is wrong. Thanks in advance for your help.

I recently un-installed an old version of Thunderbird that was showing a vulnerabilty and would not patch itself to the latest version for some reason (old version was in the 60s). I had all mail stored in a non-standard folder on my D drive so that it would be included with my backups. After uninstalling, my non-standard folder is still there. However, the location where Thunderbird was originally installed was removed and that is not included in my backups.

I installed today the newest version of Thunderbird, but I cannot get it to open my old mail. I'm able to login to my accounts, but I need to access the email stored in my non-standard storage file.

I have downloaded the addon cardbook. Now, how do i find my old address books that existed prior to the addon? Please do not leave a single step out on how to migrate back or forward or what ever i have to do to get my old tb moved to the new cardbook tb supernova. Thank you.

Hi. I love Thunderbird! But I cannot use a Gmail account.

It all started when I changed the underlying password for my Gmail account (for routine security). I changed the password too on my Thunderbird client for SMTP and IMAP.

But then it popped up with: https://accounts.google.com/v3/signin/identifier?app_domain=http://localhost& [etc]

it keeps giving me this message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

I've tried to read online what's going on. I've deleted the account and tried to set up again, and closed Thunderbird. It keeps doing this. I've checked Google settings ... nothing untoward. It doesn't have a link to Thunderbird still.

What can I do?

Thanks, Dan

Upgraded to Sonoma 14.5 on iMac and when trying to open Thunderbird, I get the message "Thunderbird" is damaged and can't be opened. You should move it to the Trash. What do I do?
