Hello, I have a problem with Mozilla Thunderbird. After adding a new email account, it works correctly, but after closing and restarting Thunderbird, the account disappears completely.

In the Thunderbird profile folder, there is no standard prefs.js file. Instead, I have multiple files such as prefs-1.js, prefs-2.js, prefs-3.js, etc.

I use Windows 11 with McAfee. I found information suggesting that this issue may occur when security software prevents Thunderbird from correctly saving or updating prefs.js. I have now completely disabled McAfee.

Could you please advise me how to safely restore the correct prefs.js file and make Thunderbird save the account configuration properly?

After many succesful years using Thunderbird suddenly the update 5.18.0 (64-bit and reporting as supposedly up to date) ) has completely lost all my folders and screwed up my email accounts!! I've been having an absolutely ghastly time for weeks trying to make sense of it and just feel like junking it...HELP! My email accounts that have been working successfully without problem for many years now sometimes send and not receive or the other way round, not send but receive. Additionally I cannot access critical and important emails (serious medical, legal and personal). I tried to change the staus of the accounts from POP to IMAP and ...lo and behold, the program does not allow it!?!? Why the hell not?

Hi,

I am having trouble deleting an email account in Thunderbird and hope you can help me resolve this issue.

When I click the "Delete" button, nothing happens. The "Set as Default" option is also unresponsive. I have already tried running Thunderbird as an administrator, but the problem persists.

Additionally, I tried setting up the account on my phone using QR codes, but it fails to load all my accounts. Out of 5 QR codes, Thunderbird only successfully scans 3, no matter what I try.

It seems like there might be a bug or corrupt profile data causing this, but I cannot locate the root cause. Could you please advise on how to fix this or manually remove the account?

Best regards,

I want to delete an account.

When I go to the account (which is not the default btw) and I click the red "Delete" button, nothing happens. No dialog, no nothing. I could click it all day, it's just a button. The click handler for it is clearly not working. It's either trying to call the wrong method, or the method is erroring out. It's just a button, being clicked.

Is there a way to manually delete an account from my Thunderbird without trying to use this **very clearly broken** button?

I have version 156. There is no account actions button so there is no "remove account" interface any longer. I have searched the internet high and low already and am at my wits end on this.

It really should be as easy as "Click the Delete button under Account Settings and then click confirm."

I've also seen several other people online post this exact same issue without resolution. What's up?

If you don't know the answer, please don't waste my time with "maybe this" or "maybe that" answers.

Thank you.

I'm trying to remove a couple accounts that I no longer use in Thunderbird. A window keeps popping up asking for a password, but the mail service is no longer available. When I click on the red delete button for that account, nothing happens. I've deleted all the mail in one of them which I was able to do as I thought I might need to do that first, but I still can't delete it after that. The other one won't even let me delete the emails. How do I delete these so I stop getting asked to put in a password for accounts that are no longer valid and I don't want anymore?

My T-bird is not receiving incoming messages in one E-mail account. How can I add back an IMAP server on an existing T-bird account after T-bird deleted the line with the saved password and IMAP server for that account? I tried to change the IMAP server address for an existing T-bird account, but T-bird and/or my ISP deleted the saved password and IMAP server line for that account in T-bird's Saved Passwords table, so T-bird cannot get incoming E-mails. The IMAP server address still exists in T-bird's Tools -> Account Settings -> Server Settings page, but NOT in the Tools -> Options -> Privacy & Security -> Passwords -> Saved Passwords table. I would like to add an/the IMAP server back to the account without deleting the account, and re-entering all of its settings again. I have not figured out how to do this.

I tried to change the IMAP server address for an existing T-bird account, but T-bird and/or my ISP deleted the saved password and IMAP server entry for that account, so T-bird cannot get incoming E-mails. I would like to add an/the IMAP server back to the account without deleting the account, adding all of its settings again, and waiting 6 hours for T-bird to re-download all of the most recent 10,000 messages in the Inbox and all of the 15,000 messages in other folders again. The SMTP server and its saved password are still in the Saved Passwords table.

Hello

I use Thunderbird (153.2 0esr) on a win 11 PC.

I have some POP email accounts with btinternet which work.

I want to change. them to IMAP accounts using the same email addresses.

Before I do this I have several minor problems within Thunderbird, which I would like to sort out before copying the Thunderbird files as a backup.

Rather than list them all, it's possible that fixing the first may solve others.

When I open Thunderbird I see this message... see FIRSTCalendar if it hasn't been inserted into the text

I have never (knowingly) used BT's calendar. Clicking cancel removes the report and does not stop any of the BT mail accounts working.

I tried using the username and password of the default account but password of the default account without success. At a later stage this appears...

See SECONDcontacts if not inserted here

The address displayed is one that I have deleted from my BT Email account.

It is no longer shown as one of my BT accounts in the email management page in MYBT or in Thunderbird

Again, clicking Cancel does not stop my BT email accounts working.

Any suggestions how to fix this, would be welcome.

Cheers

Dave

My family I are using Thunderbird 153.2. The affected accounts are all Yahoo POP accounts. IMAP accounts (Gmail) are not affected. Not sure if there was a Thunderbird update prior to this problem. Yesterday I saw the Yahoo OAuth dialog panel for no reason, didn't think too much about it and kept ignoring them thinking it was a glitch. That was a big mistake. I'm now having issues downloading emails from Yahoo. Previously when this happened a few years ago, I deleted cookies. That didn't work this time. I should have read support articles first. After reading support articles, I tried enabling cookies and allowing cookies from Yahoo, but I'm not sure which website to use (is it mail.yahoo.com?). I went into config editor and set mailnews.oauth.usePrivateBrowser to true.

There are 4 Yahoo email addresses (I'll call them A, B, C, D). I am able to access all 4 yahoo accounts by webmail (email address and password). We use account A, B, and C the most. Account A seems to be the most stable however emails to A's inbox will show up in A, B, and C's inbox in Thunderbird. For some reason messages in A's inbox will go to trash in webmail as soon as Thunderbird checks and downloads emails from all accounts. Which is strange since I have always set A to leave messages on the server until I delete them. B's emails are not downloading to Thunderbird at all and are staying in the inbox. I am hoping to access the OAuth dialog box for each account to properly configure them but have been unsuccessful so far. It's been a stressful 24 hours. What should I do? Should I reset the passwords for all yahoo email accounts? Delete the Yahoo email accounts and add them back? Or should I uninstall Thunderbird and reinstall? Any suggestions are appreciated.

The authentication is not working with many of the directions I have found online. I create an app password from logging into AOL website and have no where to put the password. If the password request is made is does not accept the password. Things aren't where the direction indicate. Getting the connection to request the password sometimes works but no password works. I tried the app password and rejected and multiple other password don't work.

Based on the latest version of Thunderbird where things seem to be changed, how to specifically set up this new authentication.

It's driving me crazy,

Thanks...Carl
