When I try to open Thunderbird it keeps giving me a message that it is trying trouble install a new helper tool and asks for my password. I do so, hit the Install Helper button, and then nothing ever happens. I get a spinning beach ball and it never opens no long how I wait. I would be very grateful for any suggestions or advice on what to do.

Using Thunderbird forever, on my PC and also on my Android. On my PC sending messages stopped working "suddenly". (That means I did not change anything in Thunderbird. Windows related settings - who knows.)

__________________ Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.ionos.de failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again. __________________


I have checked the SMTP server settings again, but it didn't solve the problem. I have changed my password of my e-mail account to anew one, reinstalled Thunderbird and recreated my account, but without anything changing. Receiving works, sending does not. Tried to install Outlook (sorry, just temporarily, I hope :) ) and there everything works just fine.

Maybe some Windows Firewall setting? Didn't find anything that seems to prevent Thunderbird from sending thou. Do you have any idea?

I am using Thunderbird on a Macbook Pro 13-inch mid-2012, in a POP3 account

Thunderbird 140.10 is generally running fine, except that some sub-folders are not visible in my Thunderbird email tool view. I have a hierarchical

I have tried repairing the parent folders, but that had no effect.

The corresponding .sbd files are clearly visible in ~/<user>/Library>/<profile>/Mail/Local Folders/pop-server.<account> and being backed up in Time Machine backups.

Curiously, there is a much-truncated replica of some .sbd folders in Local Folders named /<folder-name>.sbd, all dated in 2013, yet the folder was created in 2017. I presume these refer to an update of Thunderbird that left some trash, and of no consequence. These are parallel to Archives and Archives.msf files.

Please advise on how to disambiguate this structure and recover views of existing mail folders not being displayed.

Since April 9, 6:14 PM CDT, most folders (e.g., Drafts, Templates, Sent) on my primary laptop in my primary POP email account, [edited]@bdcusa.com, have disappeared; and ALL SUBfolders in my Inbox have disappeared. Over 185,000 emails have vanished overnight!

On my primary laptop, I'm using Thunderbird 149.0.1 (64-bit) on the release update channel, still running 64-bit Windows 10 Professional, and have nothing backed up to the cloud.

Fortunately, on my secondary laptop, I'm using Thunderbird 115.18.0 (32-bit) on the esr update channel, running 32-bit Windows 7 Professional. I say, "fortunately," because ALL folders and emails are still there, so I know they haven't been vaporized!

How do I return all folders and emails for this email account to visibility and access on my primary laptop? Detailed directions appreciated.

So I have Thunderbird set to autosave every 5 mins.

I was drafting an email, where I had written quite a lot of text (as a reply) and for some reason my text went missing and there was no undo in edits

So I quit and went to drafts, nothing there.

I checked and autosave is on for 5 mins.

hit reply again. typed in some text, set a timer for 12 mins, quit.

Again, no save.

So why is "Auto Save ever " x mins not working?

We installed Mozilla Thunderbird to manage our clients’ email accounts. Recently, we deleted one client’s email account from Thunderbird. However, a few days later, we are still repeatedly receiving login prompts asking us to re-enter the password for that account.

For your reference, the account in question is a Gmail account.

It seems the client may have changed their email password, but since the account has already been removed from Thunderbird, we do not understand why the application continues to request login credentials for it.

Could you please advise on the cause of this issue and how to resolve it?

Thank you for your assistance.

Hello, I use Thunderbird 140.10.0esr, installed as Flathub flatpak on Fedora Linux Kinoite. I just found out I have a folder in /home/<user>/.var/app/org.mozilla.Thunderbird/.thunderbird/1tniiwpw.default-release-1/storage/default/ called https+++www.googletagmanager.com. I wonder why I have this and what it does in the Thunderbird settings. It has something to do with Google's LLC, but I don't want to be part of that. I removed the folder completely and hope it won't come back, but I wonder. Who can tell me something more about this folder? Thanks.

As so many have experienced, but I have yet to find the actual solution, I will bring up the issue.

I recently purchased a new computer. Installed Thunderbird, created all the mail accounts I have and... no problems. All the accounts, once created, populated with emails. For 3-4 days, there were no issues.

Important to note: I let TB use all the default settings. And once everything was up and running >>>>I did not change anything<<<<<.

Then a few days later, I started getting the following messages for two accounts that had migrated from q.com to myctl.net. Entering the 100% proven-correct password results in the know endless-loop of entering the password and the same pop-up error message. The PW is 100% correct as I can go to Centurylinks' website and login using that same, exact password and read my emails.

I've spent enough time trying all the suggestions here, reddit, facebook etc so I'd thought I'd see if anyone has actually found a solution.

A few months ago I installed Thunderbird onto a new PC having previously used it on a previous PC (so I'm not a newbie).. However I'm seeing a persistent issue that I never saw before...

I've a regular contact whose name I won't specify but let's call him Roger Smith. What happens is that whenever I post something on a forum (such as this one) and somebody replies, the replies look as if they came from Roger Smith - even though he's got no connection with the actual forum.

It doesn't happen with every forum - for example it doesn't happen with this one - but it does affect most of them. Has anyone else ever reported this and is there anything I can do to correct it?
