Thunderbird Support Forum

Thunderbird keeps asking for my password and password manager doesn't remember it. Each time I try to look at or respond to messages, it asks for my password --- I check the password manager box to remember it but it doesn't.

Should I delete thunderbird and then install a 2020 version where this was not a problem or is there a way to solve the problem with the latest current version

Peace, Alan

I sent a message a while back about slowness with 115, which I had to download because I had a crash.

There were various suggestions, but no solutions to the excessive slowness with 115. This culminated to day in a long 'no reply' mail which suggested the issue might be the virus checker.....

I checked again the various messages about 115 - most were archived, only one month since they were posted!!

Is there an issue with 115?? I saw a thread which asked was I having issues with it, my answer is yes, is there nobody out there with a suggestion??

Open thunderbird up and want to print an email. Most of the time the printer is the default. Once I print and then go to the next email to print, the default printer is gone and the only option is save to PDF. I can close thunderbird and reopen it and seems to alleviate the issue for a few times then back save to PDF only. Strange issue. I have reinstalled thunderbird a few times. All other programs on the pc I print from always use the defaut printer.

I tried to update Mozilla Thunderbird to 115.5.0. Now I can not receive emails on my computer. The message I received said, Error: Platform version 115.4.0 is not compatible with version 115.5.0. How do I "return" to 115.4.0 so I can have access to emails on my computer? I can receive emails on my cell phone. Thank you.

Upon initial setup, Thunderbird says the ISP is recognized and auto-populates all the settings. Well of course these settings don't work and I'm unable to log in and receive some sort of message saying it didn't work. If I login using a browser via cellphone, I'm provided with the list of settings to use with email clients which is as follows:

Domain: @hot.rr.com SSL: On for SMTP and IMAP Protocol: IMAP Incoming Server: mail.twc.com Incoming Server Port: 993 Outgoing Server: mail.twc.com Outgoing Server Port: 587 Requires Authentication: Yes, or checked

Using these settings in manual configuration results in receiving the "Thunderbird Failed To Find the Settings For Your Email Account" message. The only difference between the settings that were auto-populated and the settings provided by logging in via web browser on a cellphone are the incoming/outgoing servers. Auto-population had them as mobile.charter.net, and they're listed as mail.twc.com by the email provider to use with email clients.

I'm trying to solve this problem for someone else and they happen to have the same email domain as me so I can fiddle with it without having to be at their computer with their passwords, etc. Presumably if I'm able to find the solution it will work for both of us. I don't normally use Thunderbird or any other email client, I just use web based email but they prefer to use a client. However, I'm doubtful that it will work considering the fact that settings provided by the email provider don't work.

Any input is appreciated.

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

Every few days, the index pane of some folder gets corrupted. Repair (right-click, Properties, Repair Folder) fixes it. Then a few days later this repeats, with a different folder. I have three IMAP accounts and this occurs on more than one of them.

Any suggestion for finding and fixing the underlying problem?

Thunderbird was working great until today... you "offered" me an upgrade to SuperNova 115 after which I am no longer receiving any incoming email. Does not even ask me for the password on startup as the old version did. I have checked the Windows Firewall and added Thunderbird.exe. I need help getting this to work or reverting back to previous version. Also, I recently lost a great deal of pop mail from the inbox and would like to know why - it was telling me I could not Compact the Inbox due to not enough space or not having permissions - neither of which should have been a problem. Please don't make me switch to Gmail!! Help......

Hello, I'm using Thunderbird (and before Netscape Messenger) already 30 years. With this new version 115.4.1 (32-Bit) I'm now experiencing the symptom, that, when I reopen one of the mailboxes the focus is not in this mailbox on the last read mail as it was always in earlier versions, it now focusses somewhere so that you always have to scroll to the point where you have been last time.

When composing an email and attempting to select an address from the 3 email accounts I use in Thunderbird, I am having difficulty selecting the email address I want to use. I'm clicking on an email address that opens Thunderbird in a compose window when this happens. It is a new issue but has been present a couple of weeks at least.

After loading the latest update, I can't send emails. Spamhaus is blocking them. this is an example of the error message... this is a business I have emailed before and they are in my address book, it is doing the same with other addresses

Sending of the message failed. An error occurred while sending mail. The mail server responded: Service unavailable; Client host [68.105.172.193] blocked using an77miiefpoizgkgitohtqs2qa.zen.dq.spamhaus.net; https://www.spamhaus.org/query/ip/68.105.172.193. Please check the message recipient "service@renaissance-printing.com" and try again.

After upgrading to Thunderbird 115 I've tried reading a long email scrolling down to view the lower half. After about 30 seconds it Thunderbird automatically scrolls up to the top of the email again and again without even touching the mouse. Thus making it difficult to read the entire email.

This version of Thunderbird is installed on a Macbook Computer booting up to Windows 10 operating system.

I've tried turning off auto scrolling and hardware acceleration with no change in behavior.

Should I roll back to an older version of Thunderbird or does anyone have a solution to try?

Thanks you for any suggestions.

Just about everything seems slower with 115 from sorting a large column, loading emails at startup, opening an email in a new window, etc. How can I troubleshoot this? thanks, todd

I have never needed to see every single email in my inbox when I first open Thunderbird but I'd assume it trying to load everything is why it freezes for a few minutes every time I open it.

Cannot send or reply to emails. Can receive them fine. Alert message says "An error occurred while sending mail. The mail server responded >jlheiman@charter.net< sender rejected. Check account address settings and try again." Account settings are correct. What do I do?

Hello. Currently receiving the following error pop-up with Thunderbird 115.4.1 on Win 10 22H2:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

This occurs when fetching new email from an sbcglobal.net POP3 account. Settings: inbound.att.net, port: 995, SSL/TLS, OAuth2. These settings have worked successfully for years until yesterday NOV 6 2023.

I have several other POP3 accounts all using the same settings shown above but none of them are triggering the pop-up error.

Can an expert please advise the specific conditions that trigger this error so I can determine where the fault lies? Example: Is this Thunderbird's interpretation of an error condition being transmitted by the email server requiring interaction with service provider? Is this Thunderbird's response to an internal problem like not enough disk space? (even though there is plenty)

A solution would be nice, but an explanation re: the triggering mechanism is absolutely required. Thanks.

Hello, Since the update to Thunderbird Supernova from version 102 upwards, emails in several email folders are automatically deleted or hidden. The properties in the respective folders are listed under Retention rules: Do not delete messages.

The emails displayed in the folders no longer correspond to the contents in the folders. Example: A folder displays: 7, properties in the same folder displays: 1226 with 447 MB. It looks similar in the other folders.

How can I ensure that all available emails are displayed in Thunderbird again?

A repair with *.msf does not help.

Many thanks for your support. Erwin
