When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

Hello everyone,

I started using firefox actively a year back or something like that, last couple of months it started driving me nuts as it started updating every time I launch it, which is very annoying even if it takes only 10 15 seconds, I sometimes need to check something really quick and I have to wait for it to finish installing an update, even though I checked the setting for it to do so in the background, it seems to only do it after I launch it disrupting my workflow, which made me switch back to Chrome temporarily, is there a way to fix this?

created new accounts but sub-folders different, missing, new, & new icons(?)

For many years I have had 2 Accounts in Tbird. They are POP. I just created two new accounts, and am confused by some differences in appearance. These are IMAP. Do IMAP accounts populate the sub-folders based on a structure present in the IMAP provider?

1) there is a new sub folder "All Mail"

2) No Junk folder. There is a Spam folder. Did some idiot change the name in an update to Tbird, just to fark with long time users? If so they did a poor job, since the Account Settings still has a tab for "JUNK Settings" and the toggle asks where to move the JUNK. Creating synonyms is bad practice, because nobody knows if they are in fact synonyms. One would presume they are not.

3) In the index listing of accounts, each account has an icon to its left -- concentric circles with a padlock. And I have not noticed that icon before, I'm wondering if my old accounts suddenly have a different icon (which strangely matches the new accounts' icons). The sub-folders all have unique icons for each type (Inbox, Sent, etc)

In choosing where to place sent mail, there are two toggle choices to Place A Copy In: 1) "Sent" folder on { [circle&lock icon] ACCOUNT_NAME 2) "Other { [SentFolderIcon] Sent on ACCOUNT_NAME I don't grasp the difference. Would 1) keep the messages on the remote IMAP system? I notice that my old POP accounts are using option 1) & mail is kept locally.

3) The new accounts have "greyed out" italicized subfolders "Folders" and "Labels." Are these associated with being IMAP, or did some Tbird update add them? What are they for?

I was finally forced to upgrade from win7 (which worked) to win 10 (me no likey) because of a required program which would not even install on win7. After the upgrade, which obliterated my hard drive of several important things, I am reinstalling TB. I always used an NAS directory for Thunderbird, and have email records going back nearly twenty years. I installed TB 115 and have tried several ways to get it to recognize my profile directory on the NAS to no avail. I tried copying data into the default directory the 115 install is looking at. The about:profiles shows it is looking in the correct directory, it produces a parent.lock file in that directory when I run the program. It does not give me my email, or contacts. I do not use the calendar or to-do lists.

My system is an AMD K6-6400K with 16 GB and a 500 GB drive. Though programs are loaded on the drive ALL data is stored in an NAS. There is about 375 GB available on the C drive.

I have used the cmd line to pull up profile manager, added a profile, pointed it to the data that is on the NAS, a parent lock file is created there too but it shows me no mail.

I have edited the profiles.ini file manually to have the program look at the directories, both the NAS and a local directory which has had the old files entered. Neither worked.

I tried opening TB and creating a new profile and pre-loading the info there, nothing. I've been at this for days now. I have uninstalled and removed manually all TB folders and reinstalled older versions to give that a go but without effect. I am no Luddite (Many years ago I owned a system integration, assembly and install company doing networking for the military as a civilian contractor.) but someone has to explain this to me like I am a five year old. There is no reason having my email back should be this difficult!

PLEASE give me a hand?

My TB directory appears in C:\Users\owner\AppData\Roaming\Thunderbird My old data folder was on a network drive at M:\Users\owner\AppData\Roaming\Thunderbird\profiles\k5zbs5az.default When I manually enter the M: address in the profiles.ini file, it "corrects" it to C:\Users\owner\AppData\Roaming\Thunderbird\ even though the switch 'relative' is off.

[Profile1] Name=default IsRelative=1 Path=Profiles/zpfeu8eu.default Default=1

[Profile0] Name=default-beta IsRelative=0 Path=C:\Users\owner\AppData\Roaming\Thunderbird

[General] StartWithLastProfile=0 Version=2

[Install5D388C1349709B37] Default=C:\Users\owner\AppData\Roaming\Thunderbird Locked=1

Running the Mozilla application with a specific profile using command line arguments brings up the program but no mail. It creates a lock file in the correct directory, but no joy.

I get no pop up error messages.

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

I can still receive and send e-mail from my phone and tablet (using BlueMail or GMail), but I can't do either from my Windows laptop with the new Thunderbird 60. If I reinstall the earlier version, (Thunderbird-Setup-17-0-8.exe), everything works. Going to Yahoo to change my password, as one solution suggests clearly does NOT address the problem, as the only thing that does not work is Thunderbird.

I just replaced my 5 year old Windows computer with a new Windows computer. When I loaded Thunderbird on my old computer I had issues receiving my e-mail. My e-mail provider tech support was able to get me set up so that my e-mails went to a G-mail account and were forwarded to the computer. I used this setup for approximately 5 years. During that time I created several folders in Thunderbird and they have several important emails stored there. I setup my new Windows PC this past week and downloaded Thunderbird. To my surprise, I was able to set the program up so that it works without having to go through G-Mail. My issue is that I want to copy the e-mail folders and my address book from the old computer and move them into Thunderbird in my new computer. I have looked at your support page and I am concerned that when I move files from the old to the new that I will lose some e-mails and the few folders that I have on the new CPU. I would appreciate your direction and instructions on what I need to do to accomplish this task. The old computer Thunderbird files were up to date. Updates were completed as they came out. The new Thunderbird appears very different than the edition that is on my old machine. Thank you for your assistance.

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

I am using a Samsung Chromebook Pro V2, running Debian, and installed Firefox using the Flatpak command "flatpak install flathub org.mozilla.firefox". The Firefox icon appears in the Linux apps group and I have opened Firefox using that icon.

How do I get links in my Linux apps to open Firefox and take me to the URL?

Thank you and Happy New Year, Abe

I am trying to get my contacts from Windows 10 Mail , to Thunderbird , first off , i cant find the contacts in Windows 10 mail ( i can't find the actual CSV file/folder/location , second , if this is a common issue why doesn't Thunderbird make it easier to transfer contacts , just like all the other email programs do ??? , i am confused as to why its such a pain , i am also not impressed with the speed Thunderbird has in actually sending emails , Widows 10 Mail is 10 times faster at actually sending the mail.... , the only reason i was going to switch to Thunderbird was so i can send more than 1 picture at a time in a email , which Windows 10 Mail has a problem doing and its taking forever for support to help , but if i can't easily get my contacts transferred , i am back to square 1 ,

I need a step by step in getting my contacts saved/found in Win 10 Mail , and get them into Thunderbird ... any help that actually explains the entire process is needed , as some of the links i have seen in other posts just say to save the file , but it does not tell you where the file is and where to save it (some said something about Office ???) , it makes no sense why this has to be so complicated , all i should have to do is go to "Import Contacts , choose the email program they are in , select it , and import it , that is how every other email program does it , if this can't be done without spending hours trying to hunt down the info , maybe it was a bad idea thinking this is a good email program , so far , i am not impressed , if it gets better then fine , but if it continues like this , its getting un-installed and was a waste of my time

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

System is win 11, latest TB, personal gmail account of long standing. I want to use TB as my email program for gmail. After installing TB, it asks for my gmail login and password, and recognizes the account, defaulting to IMAP, Oauth2, etc. When I press "done", I get a google screen saying that TB want authorization to access gmail files. But when I press "allow", the TB page shows an error message under the password field reading "Unable to log in at server. Probably wrong configuration, username, or password." I understand it is looking for my gmail username and password, and these are correct. I have tried this many times, including with variations: removing and reinstalling TB, creating a pw just for TB in gmail (subsequently deleted). I have read all of the gmail installation help notes at Mozilla. Most relate to a 2022 change in gmail re Oauth2. Nothing helps. Any advice?

I would like to know how I may transport Thunderbird from an old computer to a new without losing data. The old computer still is working. I do not have gmail, though I am considering going over to it.

Note: For some reason, I cannot check the box below, requesting that I receive an email when someone answers the thread. Please email me when someone answers the thread.

Can current Thunderbird (52.5.2) still import old mail from Outlook Express (on Windows XP SP3)?

Or should I try to install an older version like v38.5.0?

I also have my mail in Outlook 2003 & 2007, but I read Thunderbird hasn't been able to import from a .PST for a long time (since v.17 or so). Let me know if I'm on the right track (and which track is best). I stuck with Outlook far too long. Any help would be greatly appreciated.

Can someone tell me a step by step method of moving the profile folder from the c drive to the d drive? The reason is that I am migrating to a new computer as the c drive in the old computer is full and I don't want to fill up the c drive in the new computer. Thanks Julian
