My local folders are missing. There is nothing in my profiles to recover from. This is the second time this has happened after a Thunderbird update. Last time the local folder were found in my profile and I was able to restore them, This time there is nothing to restore. Has this happened to other users?

Greetings! I downloaded Thunderbird for my new Win11 desktop, but it gave me an ESR version 128.9.1. It's working fine, but can i just move to the current 137.0.1 version? If so, how do I do that - just grab the current version and install on top of the ESR or should I remove the ESR first? Thanks in advance!

There must have been an update for Thunderbird that screwed up the way I have been using Thunderbird for years now. I had sub folders under inbox. For example, I had an investment newsletter go into a sub folder under inbox labelled "inv". I had a filter set up to move emails that had the name of the newsletter in the title to go to that "inv" folder. In this new version of Thunderbird, those separate sub folders are gone. The filters are still there but the folders are gone. Now all emails just go into the inbox. Is there a way to roll back to a previous version?

TIA Eric

Could someone please tell me what the latest version of Thunderbird is on the Release Update Channel? I am on version 139.0.2, and when I check for updates in the app, it says that Thunderbird is up-to-date. Is version 140.0 not going to be available on the Release Update Channel?

Hi,

Thunderbird Desktop is now available in the Monthly Release Channel, with version 136.0 released on March 4th, 2025.

More information about this release is not yet updated in the Release Notes.

Currently, only information about the ESR channel is available in the Release Notes.

Hello, I have Mozilla Thunderbird version 128.12.0esr (32-bit) on a Windows 10 laptop On the Help/About Thunderbird it says update failed. I have clicked on download and have version 139.0.2 in my downloads folder. When I try to install it all goes well until I get a message "Your computer must be restarted to complete a previous uninstall of Thunderbird. Do you want to reboot now?

Yes No " I have rebooted several times now with the same results. What do I need to do to get the update Regards Peter Norris

I didn't know there was a non-ESR version of Thunderbird until I found out by chance a few days ago! Since the latest update to ESR 128.5.2 has crashed 11 times this week, I would like to move to the latest version (64 bit?) non-ESR. There must surely be an official Mozilla step-by-step guide to doing this?

I recently changed onto the new release channel by installing version 136. I now find that this new release channel appears to have installed version 138, but it is reported as a beta version. I do not want to use beta versions, as I am having a lot of problems with it, so how can I return to a stable release?

I recent got the new thunderbird update. However i also loss all my saved messages and local folders and my contact email addresses. I really need that information for some IRS imformation. Plus u also get nothong but a bid Donate now message in the body of thunderbird. I have already donated several times. I need my information now. I am quite upset about this loss is data and email addresses.

Dear demons, when will you release a new update that will fix the old update? When will all the normal features be working? It's time to get back to real work for the benefit of society.

Hi

My version of Thunderbird has just been updated automatically to 140.Oesr (32-bit)

I now cannot enter hyperlinks (Ctrl K) into emails.

The text appears in the email but it is not underlined.

I have also sent the emails to myself and the hyperlink is still not clickable in the received email.

I was able to enter hyperlinks in the previous version of Thunderbird.

I hope you have a solution because I use this facility frequently.

Thank you.

Brian

Your latest request for donations has evidently come with a forced upgrade which I did not authorise. I have been happily using an older version of TB because it supports my add-ons and themes. Now because of your uninvited intrusion they no longer work. Furthermore it seems that I can no longer download an older version that supports my requirements. NOT HAPPY!

I use Thunderbird on two user IDs on the same Mac, which is running macOS 15.3.1.

I usually run Thunderbird updates on user 1, but this time I ran the it (to 128.7.0esr) on account 2, and I can no longer launch it on user 2. (Note: Neither user is an admin account.)

Steps: 1. On user 2, launch Thunderbird. 2. Get the dialog that there's an update to 128.7.0esr. 3. Click the Restart to update button. 4. Get the dialog that there's an update to 128.7.0esr. 5. Click the Restart to update button. 6. Get the dialog to enter admin ID and password for installing the Thunderbird helper. 7. Enter the admin ID and password and click OK. 8. Get a (surprise) dialog to authorize Thunderbird to discover my devices. 9. I choose to deny.

Expected result: Thunderbird relaunches, now with 128.7.0esr. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

10. Log off user 2 and log on to user 1. 11. Download 128.7.0esr from the Mozilla website. 12. Check the hash. 13. Install, choosing to replace the old Thunderbird in the shared Applications folder. 14. System Settings, About, System report, Applications 15. Verify the signature is signed by Mozilla 16. Launch Thunderbird

Expected and actual result: Thunderbird launches and I can use it normally.

17. Log out of user 1 and log into user 2. 18. Launch Thunderbird

Expected result: Thunderbird launches and I can use it normally. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

I'm guessing there's some manner of residual file that's preventing Thunderbird from launching on user 2. I've verified Thunderbird is in the system's Application folder and not in user 1's files.

How do I clear the pending install from user 2 so that Thunderbird will launch for user 2?

I'm on the Release channel, but was updated to 142.0 Beta. Surely this is wrong. I am not on the Beta channel. I just want to stay updated to the most recent stable release.

Hello, I reported this problem and you replied with a solution and that was to downgrade to version 142. My question is: Then what ? Will I be stuck with version 142 for years or is Thunderbird working on a solution to this problem because presently updating to any version such as 144 only continues to erase local folder contents. Thank you for your support Douglas Noades

Enough is enough—every update brings problems, crucial add-ons stop working, and now drag and drop attachments have stopped working. It's really inconvenient. Maybe it's time to stop this nonsense and implement paid subscriptions or purchases, but in a way that makes everything work.

I have Thunderbird installed on a Surface Pro running Windows10 and on a Surface Pro running Linux Fedora. When I use the Windows10 computer to prepare a Thunderbird export file for the profile, the Fedora machine Thuderbird import command will not read it.

The Windows10 machine has Thunderbird 147 and the Fedora machine has 146. Is the difference in version responsible for the failure to import the profile files? Or is it something else?

If the difference is the version of Thunderbird, then how do I get 147 on my Fedora machine?

If it is something else, what do I do so that I do not lose saved emails and calendar data from 147 version when I am running the 146 version?

I'm running Thunderbird on Mac OS 15.3. I have two POP accounts in Thunderbird; the configuration has been stable for years. This evening, I went to add a new account, and Thunderbird seemed to have decided to update itself, including flipping me over to Chrome where it opened a page about Supernova.

Thunderbird relaunched and came up with an empty "Chat" window. My usual mail window is gone -- and I can't get it back. I can't get an "About Thunderbird" window to open.

I actually can't figure out what happened. My mail appears to be gone. My accounts seem to be gone. I can't open Settings, I can't open Account Settings.

Wait, the mail accounts seem to still exist -- I can tell Thunderbird to check mail, and the POP server shows the checks happening -- but if I send mail to myself, nothing opens. Also, all of the Layout menu options are greyed out.

Help? :-)

Thanks, Vince
