Thunderbird performed an update to my email and ALL Calendar entries are now gone. Completely Empty. Past appointments, meetings etc present and future. I have been using the Thunderbird calendar for over 18 years. I need my info back if possible. I don't have the bandwidth to "find" and "fix" on my own. HELP - quickly if possible. All was working just fine 6 hours ago.

I was able to send emails on Oct 9 but haven't been able to since then so I assume there's something wrong with your Oct 10 update. I can receive emails. I selected 'reply', entered a comment. My only options after that were to save as a draft or cancel changes.

I have unsuccessfully followed to the best of my ability the instructions located here for migrating the Thunderbird profile folder to a new PC: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer (my new operating system is Windows 11 Pro). The folders appear to be installed on the new PC when I examine them through File Explorer, but they don't load into Thunderbird when I open the app.

I read somewhere in one of the comments to this article that it is critical that the versions of Thunderbird on both the old PC and the new PC must be the same. But am confounded as to how to do that. When I look for updates to the version on the old PC, I am offered version 115.10.1. But when I try to download Thunderbird for installation on the new computer, one is only offered 128.3.1esr. How, may I ask, can one synchronize the versions of Thunderbird on both computers then? Where can I find an older version of Thunderbird to download onto the new PC? Or get the version of Thunderbird on the old PC to update to the latest release?

On MacOS using the OS dark theme selection, and the Mozilla TB neutral (default) System theme, Thunderbird forces all reply message backgrounds to be black. Emails are sent with black text over black background This can only be corrected by turning off the OS theme. (An app theme is supposed to theme the app, not the content.)

So TB is forcing Mac users to use an OS theme not of their choosing or to send unreadable emails.

I can't stop thunderbird from downloading my IMAP emails every time I start my computer. The emails moved out of archives and I do not know why, then I ran out of storage space, added storage and now Thunderbird want to upload (again)--(it is over six years of emails)

Hello, After update to 128 the very useful Thunderbird Calendar Search has stopped working on all our computers. I see on the Internet reports there is not yet a solution. Hope you find it soon. Regards

When I opened Thunderbird today, I was greeted by a giant red message warning, "This is an unsupported version of Thunderbird!! Thunderbird monthly releases are not considered stable for general use." By following a provided link to the "latest stable version of Thunderbird," I found that was version 128.3.0esr.

I did not request an update. I did have Settings> General> Updates set to "Automatically install updates", so I suppose that is how I got this version. But how was I pushed to an unsupported version? Do I need to turn off automatic installs to be protected from this in the future?

I recently upgraded my computer to add storage -- Thunderbird had been warning me for about two weeks that my storage was full and needed attention. The backstory is that about three months ago my email suddenly went from archived to my active email file as being unread and available to review. It was difficult to work around at first but that is what I have done...just worked around it. About one week ago I lost access to my Thunderbird emails. I had been working to remove files from my hard drive to free up storage space. [in the end I obtained additional storage capacity] and may have inadvertently deleted Thunderbird.

Currently: I began to reinstall thunderbird. The "Account Set Up" icon it asks for credentials--I had to create a new password (which could be the problem). The next question is for me to choose IMAP or POP3; selected POP3. I get the message "available configuration" but then when it is done searching I get an error message that says it cannot login to server and "can't login to server "possibly wrong configuration, username or password." I do not know how to get this straightened out. Any suggestions are appreciated.

just had the update...1st October 2024, version 128.3.0 esr.........in the last couple of days I have had trouble deleting emails, this results each time in "not responding" eventually delete happens, but then if I try to scroll down I get the same response and delay. Should I try to go back to the previous version or is it a different problem?

We keep track of the latest version of Thunderbird via this link: https://product-details.mozilla.org/1.0/thunderbird_versions.json

Since some time it reports the 131.0 version as the latest stable version. I wonder if this is correct, because the release notes page doesn't mention this version at all.

Response from json: LATEST_THUNDERBIRD_ALPHA_VERSION  : 54.0a2 LATEST_THUNDERBIRD_DEVEL_VERSION  : 132.0b2 LATEST_THUNDERBIRD_NIGHTLY_VERSION : 133.0a1 LATEST_THUNDERBIRD_VERSION  : 131.0 THUNDERBIRD_ESR  : 128.3.0esr THUNDERBIRD_ESR_NEXT  :

https://www.thunderbird.net/en-US/thunderbird/releases/ Doesn't mention the 131 version.

When manually adjusting the version number in another release notes page, it will show the actual release notes. But it mentions that this release is for testing purposes only. https://www.thunderbird.net/en-US/thunderbird/131.0/releasenotes/

Is it possible to change the versions.json to actually show the latest stable version? And perhaps do the same as the firefox_versions.json, to also include the additional ESR channel (esr115).

Thank you in advance

I installed an automatic Mozilla update and as a result could no longer access my Thunderbird email. I tried reinstalling Thunderbird 128.3 Oesr and placing a saved copy of my Profiles on Dropbox to the Thunderbird folder in AppData and rebooting. I have tried many versions of this but always get a message saying an unexpected occur has occurred. How do I recover my email folders (inbox, outbox, and local) and address book? Together they comprise almost 6 gigs.

Everything always worked great until this upgrade emerged.

Thanks, Bob Gloudemans

I've been on Thunderbird for almost 20 years and a Mozilla fan. Have evolved a fairly elaborate configuration of local (POP) email folders, rules, calendar, and accounts to manage & organize email activity, retention, archiving, etc. I've not had to deal with Profiles in previous upgrades and don't have much experience with it.

The recent Oct 1 push of Firefox & Thunderbird 131.0 releases took me by surprise. I was able to re-implement the previous Firefox profile to recover bookmarks, cookies, passwords, etc. However, when T-Bird warned that 131.0 was Beta & unsupported I took the suggestion to download & install the current supported release: 128.3.0 (I was on 128.2.3). Then hell came.

Once downloaded, installed & launched, Thunderbird 128.3 cautioned the new profile created with T-Bird 131.0 was incompatible with previous versions and that I should create a new one, which I did. Still could not get new T-Bird to recognize previous profile, so I tried uninstalling, downloading & reinstalling 128.3 multiple times, each time prompted to create a new profile before proceeding. I tried to follow the previous profile restoration process detailed on support forums & articles, but none seemed specifically relevant to my situation.

I located my profiles in the appdata roaming profile folder, including what I think are most recent based on size of mail folders. Can't determine whether I had just one or several in use due to the extent of my setup. Could really use some help & advice to: 1) Determine which profile was in most recent use prior to T-Bird upgrade. 2) Whether more than one profile was in use. 3) Re-implement the profile I was using on T-Bird 128.2.3 with my new 128.3.0

Regards & many thanks in advance, John C Houston

PS You'll ask why I would upgrade to 131.0 from 128.2.3. Answer: it was on auto-update and 131.0 is what was pushed. No more auto-updates for this guy!

I have updated to the latest version of Thunderbird and it looks like all my account are gone. Black screen with the message "Conversations will be displayed here, use the contact list in the left panel to start the conversation"

But the left panel is blank I cannot select anything, also when I click "show Accounts" on the right top corner of the screen no information is presented.

There is something happening in the background because I can see when new email come in by a message at the bottom of the screen, however I cannot reach any of my email boxes

Any suggestions what to do ?
