Yesterday I upgraded my PC from Windows 10 to 11. Today I discovered my Local Folders are not visible. Searching tells me the messages still exist, but TB does not show the folders. I did the same upgrade a month ago on a laptop (Windows 10 Pro to 11), no problems. I didn't externally back up the messages as I am a dinosaur and don't know how, but at least they are still on the hard drive. Thousands of them though so I need the local folders back. Tried all the fixes I can find on the Community Forum, without success. Can anyone help please? Bob

Ich habe WIN 10 auf meinem PC und kann nicht auf WIN11 upgraden. Hatte Thunderbird schon installiert und problemlos im Betrieb. Leider konnte ich ab ca 19.12.2025 keine Emails mehr schreiben und empfangen. Ich habe mittlerweile zig Stunden versucht das Programm wieder zum Laufen zu bringen, aber erfolglos. Ich habe es 2 mal deinstalliert, aber mittlerweile kann ich es noch nicht einmal wieder richtig installieren (habe alle Thunderbird-Dateien - auch den Cache - auf dem PC gelöscht). In GMX Mail habe ich die Berechtigung Zugriff über POP3 u. IMAP erteilt. Ich kann leider keine jpg Datei mit näherer Beschreibung hinzufügen...

I have no idea what I have accomplished and what I have to do next. I am here because I cannot access my current email account,and neither can you. I paid $20 but I still see a pay page. Get Thunderbird installed and working. I had Thunderbird years ago and lost it, I think someone wanted me on the foxinternet.com program. Assume I am a new person to access the internet.

hi again and thanks for listening when windows updated to 11 they removed Mozilla Thunderbird ESR(x86en-us) publisher Mozilla version 140.5.0 it contained alot of data, address book and many emails. Very disappointing. Is there any thing you could do or is it forever lost thanks again geoff

The Internet told be Thunderbird is the best way to Download Linuux Mint Cinnamom. I am 94 years old and cannot figure out how to do that. Can you give me detailed steps I can take to do that?

I am trying to restore my Thunderbird/Mozilla account, and get the following message:

Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server.

Any help would be appreciated, thank you.

duplicate of /questions/1553385 thread in Thunderbird for Android section

Thunderbird app on Android suddenly stopped moving emails; instead just repopulated inbox. Uninstalled and reinstalled app; added email account and proper password. TB locked into "Checking incoming server settings" loop. Comcast properly set up; accessible from browser. Tried entering settings manually; same result. Cleared cache and data; same result.

I have been having using Thunderbird as my email package for over 10 years and lately have been having issues. I was looking to cleanup the install (version 140.5 esr) and noticed an older version of the app still exist on the computer (version 68.4). will deleting this version have any implications. This computer was originally Windows 10 but has been upgraded to Windows 11 when the problems seemed to start appearing.

I am trying to create my gmail address on Thunderbird ([edited] @gmail.com). But I get an error message: Error message start: Could not create account Incoming server is already created. Error message end. however I cannot find any incoming server mentioned for this email address anywhere in the settings or data. anyone have an idea where to search for and delete that server ? I will be very grateful for any help.

I am trying to upgrade from ESR to Release. I saved my profile successfully, went to the install page and clicked Download. Got a request to donate, which I did. Then I got a page saying Thank you, Finish installing and enjoy Thunderbird. But there is no way to finish installing and I never got a download file. I've tried multiple times, nothing happens. Help!

I have several email accounts that don't work well for me. Since Firefox has been my primary browser for over twenty years, I turned to Mozilla. I like your company's open source method and people-based philosophy. So I signed up for Thunderbird just now from your website. But I am not all that tech - savvy (I'm a baby boomer who started using personal computers at age 34 in 1984, and internet in 1990.) I'm 76 years old.

Is there someone who could walk me through setting up my new Thunderbird email account, and then moving my emails and address book from my current email server on Rackspace? And also disconnecting Apple Mail as my default outgoing mailbox, and set up my new Thunderbird account in its place?

I'm willing to pay for some help!

I installed Thunderbird on a new (used) computer running Windows 11 Pro using the old computer's mail account and password. Thunderbird seemed to connect automatically to the webmail. However, when I click on the email button the program makes me enter my name and password (already entered). Then when I click on next I get - Error Creating Account. What do I do now? Thanks.

Bought a new computer,, loaded Mozilla email added one account which took two hrs to make it in then loaded another account.. the second one came up will all my folders the first one had nothing and does not work I would like to take it out and start all over but dont want to loose the 2nd what can I do to do this. ? Thanks email to answer is [edited from public] @earthlink.net

The first problem cropped up immediately: Thunderbird has done a pretty good job for years of recognizing my email preferences for Inbox, Trash and Junk; now it no longer delivers email to my Inbox or Trash at startup. Almost all of my email goes to the Junk folder, including that from whitelisted senders. All of my individual spam filters and my whitelist are set to act when email is received, but I have to run the whitelist manually to get it to work (sometimes more than once). The only way I can get things into the Trash folder is to put them there manually, as TB apparently has forgotten everything it learned about my email preferences. I did take the opportunity to update my Whitelist (though to no avail), so I guess I'm sort of glad that I was goaded into doing so. But it hasn't helped.

As of tonight, I can't write or reply to an email or edit an email draft because TB locks up while it is "Copying messages to Drafts..." I've had to close TB ten or twelve times, and I've not been given the opportunity to make a bug comment during the closing routine.

I have emptied the TB cache in hopes that doing so would clear up these issues. Though that works well in Firefox, it didn't help with these problems.

I also am not too happy about the disappearance of the File Edit ... folder bar and its being replaced with a hamburger drop-down menu at the upper right, but at least it will suffice once I've unlearned almost thirty years of doing things a certain way.

I really don't want to stop using Thunderbird. I like the program, and I'd hate to have wasted the two solid weeks it took to get Yahoo! Mail to acknowledge its existence and let me connect to their service, which I did under duress. Not that I'm a masochist or anything.

Thunderbird kept crashing, so I tried reinstalling. When I did, I was told to agree to an upgrade. I did. But now, it can't configure my account, and I've lost everything. Using a Windows 11 PC desktop. Everything was working fine until a couple of days ago when trying to send messages ended up crashing Thunderbird if I used the enter key.
