Thunderbird Support Forum

When going from Help on menu to check for updates receive the error message - Failed to check for updates.

Running on Windows 10 with NAV - problem is recent in origin but I can't be exact as it's not my regular PC.

So far I've manually updated Thunderbird from 115.11.1 to 115.11.2 (64bit)by downloading from Mozilla website, rebooted from cold several times, and applied the fix from Norton:" https://community.norton.com/en/forums/auto-update-norton-360-v2449067835-now-causes-security-exception-thunderbird " in case it was related. It appears to be unrelated because on my regular PC the NAV update occurred necessitating the fix to the security exception error but don't have the checking for updates error.

thanks

I had trouble updating my email accounts due to an issue with the profile update. The solution for me was to delete the 42 copies of the profile and basically start over. Now I need access to some of the folders where emails were locally stored. I know where on the computer fined the folders/files of the old emails. How do I import them into my current TB profile?

While using Thunderbird, it mysteriously stopped connecting to Yahoo Mail. This happens every few years and I think it's related to Oauth2 credentials.

I generated a new secure mail key and copied it into Thunderbird but that didn't work. So then I checked online, and one of the steps in the Thunderbird instructions is: "Select 'Server Settings' for mail account; Set incoming server 'Authentication Method' to 'Oauth2'; Click on 'OK' ". But Oauth2 isn't one of the options. The choices are normal password, encrypted password, Kerberos/GSSAPI, and NTLM.

I'm using POP. Tbird version 115.11.1.

When attempting to add a second email address to Thunderbird, I get the same error message every time. I have tried updating TB and restarting my computer, here are the steps I follow, please let me know if I should include any diagnostic logs/how to get them as well.

Please note that I already have an account set up that actively works, both sending and receiving gmail. Settings > Account Settings > Account Actions > Add Mail Account Enter my full name, and email address, but leave the password field blank according to other advice on this forum, although I have also tried with entering the address. Press Continue, receive the "Configuration found in Mozilla ISP database." message. Select IMAP > Done. See a google sign in page, with my email already filled in. Select Next. Then I get a Google 400 error page, reading: "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know." If I close that popup window, there is now a message in Thunderbird saying "Unable to log in at server. Probably wrong configuration, username or password."

Images with more details are attached below, note that this issue persists after both an update and a restart. Please ask any questions that can help you help me. Thanks in advance.

Hello everyone! :)

I'm using Thunderbird for many years. Today I had to reinstall my Windows and obviously to set up my apps including Thunderbird. Unfortunately an error is popping up after I filled all of the required information. I restarted my PC. I reinstalled Thunderbird. I'm using the most popular email client in Bulgaria.

Nothing works so far. Screen shots are attached including the provided settings from my email client.

Thanks!

Trying to use my old profile on a fresh install.

After trying a few things I ended up with an error that the profile couldn't be loaded or was inaccessible.

So I did the following:

1) started the profile manager 2) removed all profiles 3) created a new profile 4) changed the name of the folder in the file system 5) copied my old profile folder to the same spot with the same name that the profile manager gave it

When I started thunderbird, I was just expecting it to load with my old profile.

Instead, I got the Account Setup screen.

I don't want to setup my email account, as I'm worried it will start downloading all my emails, and store them in who knows what profile. I could not see a way to start Thunderbird without it successfully connecting to an email server in this setup process.

Any suggestions for just getting mozilla to start and load my old profile please?

Thunderbird suddenly says "authentication failed" for my rocketmail email. Was working fine up til now. I can still log into the email directly via Yahoo. Any ideas on how to fix this.

v115.10.1 I made a mistake setting SMTP credentials, wrong protocol, and it just stays on Sending dialog. So I abort when I realize I made a mistake and come back to mail I was to send. - but 30-60s after I aborted comes an error message saying it timed out

So the cancel button does not really cancel the send attempt, it seems.

Not sure where to report bugs, so do it here. Thanks.

v115.10.1 32-bit Changed isp and email completely, and wanted to change both server name and user name. But editing server name and leaving that field I get a popup wanting to restart - problem is I need to change user name as well or no go

So it starts to try and login but fails of course, since user name need to change too.

This really need another approach, maybe not so automatic.

Changing focus from first field to next one should not execute restart. - just when leaving second field if any of first and second is changed

So going through all accounts and failed logins etc all the way is cumbersome. - dual restarts every account

Not sure where to put bug reports like this. Thanks.

In this help forum, is there a way to search for posting done by a specific Contributor? I find some contributors are very helpful and would like to see more of that person instead of reading thru a lot of posting. Thank you

I think Thunderbird did an update and now my email and my wife's emails are gone....including all of our saved emails. I believe we are using PoP accounts and not imap. Is there a way to get back all our emails?

Question 1 - Is this a real version? (as dlsplayed in troubleshooting information) Question 2 - How can I upgrade to version 115,, or do I have to delete and start again? Sub question - if I have to delete what is the best method? I just spent a few days installing and then installing 5 gig of settings and mail from Windows 10; I would hate to do it again.

Thunderbird 115.11.etc has become seriously slow when deleting or moving emails - the first one goes quickly but then it all slows down for the second and subsequent emails. I have found that this is a Virus checker issue - I use Microsoft's own defender software on Windows 11 - and have now eliminated the problem by making an exception in the virus software to the TB profile folder. My question is: how safe is this - I don't want to allow virus attacks in email but at the same time I don't want the slow software! What do you suggest? Thank you

Tired of Apple mail, want to install Thunderbird 78.14.0 on my mac mini. Am running Yosemite 10.10.5.

I can see access to the files on this site but need an installer to load to system.

Am familiar with unix can work off a console but am not a programmer, wouldn't know one end of a compiler from the other.

Can you point me in the right direction?

Hi folks! I use Thunderbird Beta (128.0b1 (64-bit)) for my email currently. I've been having a problem with some emails, mainly in my Sent folder, showing up as long strings when I try to view them. It looks like untranslated code put into plain text to me, but I'm not sure what would be causing it. I have no problem reading the email if I log into our webmail to do so. Example text from an email attached. Is this a known problem? Any ideas on how I might solve it? I like Thunderbird, but not being able to search and read through sent emails is a real problem. Thanks!

i have an old win10 machine with a huge thunderbird profile - 37.9GB size / 75.2GB disk. i'd like to move it with Tools Export / Import to a new win11 machine.

on win10 i click thru tools > export > open profile folder

and in ...\thunderbird\profiles i select yhcc00j7.dan and export it to an external ssd.

it runs for hours and then a number of these appear: "Are you sure you want to copy with file without its properties? The file %2B...." has properties that can't be copied to the new location.... Type WDSEML file size 1.02KB....".

so i check "Do this for all current items" and hours later it finishes.

on win11 i click thru tools > import > import from another thunderbird profile > choose a profile and select the folder yhcc00j7.dan on the ssd and import everything > start

for a minute or so it says "importing .... 0%" but no new profile shows up in ...appdata\roaming\thunderbird\profiles\ and then "import failed unexpectedly" is displayed.

i've tried this twice. both machines have version 115.11.1 "esr update channel". what am i doing wrong?

Guten Tag,

ich benötige Hilfe das Googlefenster weg zu bekommen. Ich möchte mich nicht über Google anmelden, wenn ich es auch über Mozilla kann. Die Anmeldedaten von Mozilla funktionieren nicht.

Bitte sagen Sie mir, wie ich das Problem lösen kann.

In dem Fenster habe ich keine Möglichkeiten die Links an zu klicken, da dann das Fenster weiß wird. Ich kann es nur wegklicken, es kommt aber innerhalb von 5 Minuten wieder. Oder ich melde mich mit google an, was ich aber nicht möchte.

Danke für Ihre Hilfe.

My email inbox is really a task list. I find that I email myself items that I need to work on so that they are in the inbox. It's a tiny thing, but it would be so much more convenient to be able to view/edit the task list alongside the email inbox. I organize my emails with the listing of emails full-height on the screen with the preview window to the right of that. I would like to be able to see the Task List to the right of the preview pane. At this point, it appears that only the Today pane can be shown there. This requested feature is supported in Outlook, but the Outlook "task list" is not as nice as Thunderbird's because their "tasks" are just emails that have been flagged - not very useful. Thanks for your consideration.
