I have a Windows 10 pc, which is current with all Microsoft and manufacturer (Lenovo) updates. Thunderbird won't run since the last update. It just gives a message saying, "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?" After several reboots, I have given up. A support forum solution from 4 years ago recommends deleting a file (global-messages-db.sqlite) at a location (C:\Users\user\AppData\Roaming\Thunderbird\Profiles\8charstring.default) that seems not to exist (hidden?) on my pc. What do you suggest? Thanks.

Several days ago, my comcast email said it couldn't connect, and after trying a couple other things, I removed the account and tried to add it back on. When I try to add it as an IMAP account, it pulls up a window that loads for a minute then says "Unable to connect. An error occurred during a connection to localhost." On the thunderbird window where I entered my password, it says "Unable to log in at server. Probably wrong configuration, username, or password." I logged in on a browser, so I know the username and password are correct. I tried adding it as a POP account, and that worked fine, but I need it as IMAP.

Hi all,

Sorry for asking again, but after reading all the posts here the problem is still occurring.

When I launch Thunderbird, I'm asked for new data (Account Setup), like there is no profile available.

The application seems unable to locate or recognize my existing profile, but the profilefolder exists and its almost 90Gb of data. Should I complete Account Setup windows with my data?

Please help me! Tried with thunderbird -p command to repair or select another profile but with no success !

- installs.ini Default=Profiles/xxx.default Locked=1

- profiles.ini

Default=Profiles/xxx.default Locked=1 [Profile0] Name=default IsRelative=1 Path=Profiles/xxx.default Default=1 [General] StartWithLastProfile=1 Version=2

User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:115.0) Gecko/20100101 Thunderbird/115.11.1 OS Windows_NT 10.0 19045

Thank you !

Almost daily I get a message to download or dismiss update. When I dismiss the message, it continues to pop up. When I hit download, nothing happens. This is locking up my computer at times & slowing everything down. I actually don't see the need for daily updates. What is causing this and how can I stop it?

I am currently using T-Bird 115.11 on Windows 10. Not that it matters much, because I have had this problem continually for years with various editions of Thunderbird on Win7 as well. Often when I open Thunderbird, I discover it has created hundreds and even thousands (today 65,000) duplicates of emails in various mailboxes. This has nothing to do with downloading. The emails in question were downloaded weeks or even months ago, and I havev't accessed them. Another problem is that Thunderbird creates emails dated in 1970, even before anyone thought of the internet, let alone PCs or emails. Why is this happening? How can I prevent it?

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 have tried multiple times to add an email account to thunderbird in windows but I keep getting the error, "Unable to log in at server...". I know the details are correct as I'm copying and pasting them from my password manager so I'm not sure what the problem is.

This problem began a couple days ago. I have no problem accessing other sites on Firefox (and none for this site over years of use.) Can access site on Safari without problem.

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

I get the pop up that includes Add Security Exception

 You are about to override how Thunderbird identifies this site.

Legitimate banks, stores, and other public sites will not ask You to do this. Location:

This site attempts to identify itself with invalid Information. Unknown Identity The certificate is not trusted because it hasn’t been verified as issued by a trusted authority using a secure signature.

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help

I'm going to ask this question again. Has anyone seen this? If so, what does it mean? When attaching a pdf or other file to an email, I can't open it to check it before sending.

C:\Users\***\Desktop\*****.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences.

What is a helper application and how do I fix this?

Thank you

I want to setup my Gmail account that my school hosts. It has a unique domain name and Thunderbird does not recognize it as a Gmail account, but I'm sure it is. Here's what I did to solve the problem (yet no luck) First, I tried to setup with manual IMAP configuraiton by following the steps on LifeWire Article and Google Support, but it says that credentials that I'm using is wrong. It did detect the Gmail mail server though. Next, I tried to pretend that I'm going to login as a user I've created ON GOOGLE so thunderbird can recognize it as Gmail Account, then logged in with my school credential, and it failed. Probably because I've entered fake Gmail address in the form. It's very inconvenient that I cannot setup mail accounts with OAuth authentication method manually.

Do you have a walkaround for this?

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

I can't open firefox. message says "firefox quit unexpectedly" and it won't reload. I tried Force Quit. I tried restarting my computer. I tried completely shutting computer down and restarting. It happened very suddenly yesterday.

Help! I updated and now all my tabs are crashing and I'm on a deadline! I tried to rollback but couldn't find the exe. Here are the last 5 crashes:

I can't use Thunderbird any more. I open an email and I get 7 copies up across the top of the screen. Delete does not get rid of them, and I am up to over 50 at this point. Please contact me directly at [removed phone# from public support forum] when you have fixed this. For reasons I have just outlined, email is not a good way to communicate.

I assume that everyone else is experiencing this disaster.

About 2 weeks ago, Thunderbird stopped sending emails. I spent a couple of hours on the phone with tech support but was unable to correct the issue. Changed all of the settings several times, SMTP server, port, security and authentication without success. Tech support suggested using their server but that's a pain. Attached are pictures of the error messages. Thanks.

I am receiving this error message when I try to log into my router. My router has a certificate from Let's Encrypt.

What settings do I have wrong?

Regards.
