I have cleaned and re-cleaned existing Thunderbird installation; export still creates a 2.7GB file which import fails with. HOW DO I MIGRATE MY PROFILE? (Firefox migrate was smooth as butter) I have used Thunderbird for 10 years, but am ready to switch to a different mail client if I can't get it migrated. PLEASE HELP!

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

I am the tech admin at my school and one of my user's hard drives is totally full. I ran a sorted disk space command and found that the folder ~/Library/Thunderbird/Profiles/5itb4j1n.default/ImapMail/imap.googlemail.com is 57GB. The hard drive is only 120 GB! Needless to say, I need to get this off the computer. It is a MacBook Air M1 running OS Sonoma 14.1.1 (can't upgrade because no disk space!)

The user accesses her Gmail through Thunderbird. There are messages in her Thunderbird history that are not available to her in Gmail because she integrated Thunderbird previously with her Yahoomail (before we switched to Google for our mail server). So we cannot delete Thunderbird because she needs it to be able to access old emails.

I'd like to know some options for having her continue to use Thunderbird (because she likes its layout) but without Thunderbird downloading and keeping a copy of every message/attachment that arrives.

I also want to know the best way to backup her existing Thunderbird and then be able to access it in the future, so that if she does need to access her historical archive of email messages, she can.

After last update V104.0.2 fire fox will not allow me to access router to change settings message given, unable to connect, can I revert to previous version of firefox as always worked before update

I've been forced to use Windows so I installed Thunderbird 119 on Windows 11. (Please note that I've been using Thunderbird for 20 years on Mac and Linux and am happy how it's set up on those platforms)

I think the UI on Windows sucks and I want to have the same setup and same GUI on the Windows version of Thunderbird.

How do I copy all the settings or config or whatever from the version I am happy with (Mac) to the Windows 11 version?

PS the biggest piss off is threaded views within the message pane and the missing buttons at the top of the message pane. I don't want to see all the past replies in the Message Pane and have to scroll down down down down where I accidentally found the send button. This 115+ UI isn't prime time yet.

Question. How do I restore a profile from windows.old?

Details: Yesterday Windows 10 Failed (yet again , no surprise) Explorer.exe kept locking up and crashing at 1096 threads making it impossible to load/browse anything on my computer. After relogging into the OS I had about 1 minute to do anything before failure happened. (this while windows loads all the bloatware simultaneously which slows down access greatly) In short I could barely load/run mozbackup

Previously every time a windows OS failed I just restored firefox with mozbackup. Apparently that no longer works for firefox and has in fact been out of development for a decade. (tears flowing) The last time this happened ( 3 years ago like clockwork with any windows OS since XP) I moved both the profile folders to their respective locations from windows.old roaming/local to the roaming/mozilla and local mozilla folders respectively.

This no longer works and in fact causes firefox to not function at all. Since I need the passwords locked in firefox to access certain sites like hotmail.com and recover other things for my OS I am screwed. I have no Idea what idiotic concept cause the inability to manually port your profile but I need a workaround asap.

I cannot even log into mozilla.org properly without it either and was forced to use a gmail account just to post this

HELP!!!!

For context, I accidentally made my root D: folder into the downloads folder and during this time I was still able to download using firefox. But when I finally changed the folder to my default one, firefox stopped being able to download anything larger than 1gb files. I can still download small images but anything larger than that I can't download. Else, it would only just show "Failed" in the downloads bar.

I've tried: 1. Changing the download location

>Also tried reindicating my download location

2. Turned off dangerous downloads 3. Putting an exception to the sites I try download from 4. Clearing the downloads 5. Tried troubleshooting mode 6. Restarting my computer 7. Restarting Firefox

I can't download on firefox but the same files I can download on Chrome.

Hi all I recently bought a new laptop that has to be exchanged as it's faulty. I had no problem moving my profile from my win 10 laptop to the new win 11 one, however I now need to put all my emails back to my old laptop and although I can go through the import procedure when I restart Thunderbird none of the new emails are there. Any help would be greatly appreciated.

Outlook stopped working as of last night. If I install Thunderbird as my desktop email program, will I be able to set it up with my current desktop email address: [edited] @tx.rr.com ?

I've had problems with outlook since I changed network providers from spectrum to frontier. I have the incoming and outgoing server settings for frontier.

Since my current desktop email program (outlook 2016) does not work, contact me via webmail for the moment [edited] @proton.me

Thank you

Hi, In a new Windows 11 PC Thunderbird 115.81.1 (64-bit) was installed. Then I did /Server Settings/Message storage/Local Directory/F:Mail

The F:\Mail is an external USB-drive. The left pane then showed two main folders:

x@y.no Local Folders

In both of these there is an Inbox sub-folder. The one under "Local Folders" shall be set as the "Global Inbox". In many pages on the web, e.g. a MozillaZine page, it is explained how to do this. The key point here is to navigate to the "Server Settings" and clock on the "Advanced button".

My problem is that there is none; see the uploaded image.

Could anyone, please, tell me where I did my error?

Best regards; ChG

I am completly confused with migration, I want to move T/bird as I have it in Win 10 to a new machine with Win 11.

None of the articles make sense, the link to the "profile folder" takes me to a big list of things not recognised here:

C:\Users\R-LT-NOVA\Downloads\tfr data

The R-LT etc is the name of this machine.

Thunderbird is working fine but there is nothing under users>AppData>Roaming>Thunderbird although a "prifile" there does seem to point to the file above.

Thanks in anticipation.

I have a new PC. After installing Thunderbird onto my new PC, emails from my old PC are not there. Can these be recovered? I have a copy of my old PC hard drive files but not the actual PC. Thanks Jim Ferrier

I had several address books with selected contacts under my Personal Address Book so that I was able to select them for sending emails to selective groups. Unfortunately my system crashed and I had to reinstall my OP system including Thunderbird. When I upgraded to a new version of Thunderbird I was unable to migrate the contacts within those list to the new address books, unfortunately I don't remember which version caused the change except it was when they moved the address book icon to the left side of the screen. I had copied the respective sub address books to .csv files. How can I import the selected .csv files to a sub folder under my Personal Address Book? Also, how do I copy/paste individual or groups of contacts from one file to another?

Hi, sorry to ask, but my E drive (where I keep data, etc) died. I do have backup and have the whole Thunderbird\Profiles folder. I watched the YT video, but I don't get it. It should just be easy to point the whole folder to it. All my stuff on C is fine, so it does come up with the email accts and the address book. I did try to do an Import, but got errors. Please Help! I am an OLD IT guy, so I am not stupid. It should be easier than this! I will attach 2 pics. Maybe someone will take pity on me...LOL.

FYI, I use an Over 10 year old W7Prof Installation, migrated thru about 3 pc's, on an i-5 (yes, I am lazy And Love W7) and my 1TB hard drive is over 12 years old (yes, I know...don't ask), And It DIED. So you can imagine what I been going thru since last Sat!!! WHAT A MESS AND BRAIN STRAIN!

Also, I HATE Gmail Web Mail!!!

Oh, and I have donated before. I had Windows Live Mail forever, but when Googley put the OAUTH PW mod in, I had to switch. I do like T-Bird. Sorry to write so much...Thanks again...

THANKS, Sam in FL

I installed Thunderbird yesterday and tried to connect my work account, which is a Google workspace gmail account with the organization's domain instead of gmail.com. I set the servers as smtp.gmail.com and managed to select OAuth2 for authentication (this was difficult and required me to set the port at 465). I went through the permission process with Google, which now acknowledges (in a very warning sort of way) that Thunderbird has access to my account. I even sent an email from Thunderbird, which showed up in the sent folder on the gmail account and was received by the sent to account. However, I see only an empty inbox and empty local Trash and Outbox folders in Thunderbird. It's just not syncing anything (or maybe downloading anything?) from the gmail account. I need it to sync all my mail folders and my calendars as well, so two big problems need to be solved before I can use Thunderbird at all. I sure appreciate any help I can get!

I am following all the instructions. It has continued to fail for the past year. I've uninstalled ff and reinstalled ff. I've tried creating new profiles. I can import everything into Chrome or from Chrome to MSE, but NOTHING will import into ff from any other browser.

When I got a new computer, my account was automatically set up as IMAP but I could not send emails, though I can receive on the IMAP version. I went into manual configuration and copied all the configuration information from my (working) old computer to it, using its POP3/SMTP settings, but when I Retest I get an error: 'Thunderbird failed to find the settings for your email account' I've double-checked everything and am at a standstill. I really need help!

I came across this message from March 2022 -

"I read at AskLeo that I could use Thunderbird with Gmail as a way to backup my Gmail emails to my computer. I then want to backup the Thunderbird folder using a backup program to save the emails to an external drive.

On Windows 10 Home, where do I find the emails that Thunderbird is downloading from Gmail? I recently installed Thunderbird 102.1.0 (64-bit) using IMAP and OAuth2 authentication. "

which describes my problem well.

The answer relates to Windows 10, but I am using Linux Mint. I think I installed Thunderbird flatpack version but I cannot find the profile to backup and although I think all my emails (around 25,000) were downloaded from gmail, I cannot find them and so cannot take a backup.

Following an automatic update the other day, everything in Thunderbird is oversized. There are in fact some things I can no longer see at all! The program has become very difficult to us to read/write emails. See the image below, a full-screen capture showing the problem . There must be a line to edit in the fonfig file to make the display look normal again. Please help me find that line!! I am visually impaired, and life is difficult enough already! tnx, Paul pgschreier@swissonline.ch
