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.

I tried to use Thunderbird today,.. to find the interface was broken, menus were blank, so no ability to look at anything., and error message inferring there was a menu config issue was all that was shown. I duly removed Thunderbird as a snap install, which took a long time as it seemed to be making a backup to somewhere. I then reinstalled Thunderbird 128.11.0esr (64-bit) on my ubuntu 24.04,.. having setup the isp email credentials,.. all seemed fine,.. I then proceeded to import what I assumed was my old local folders... And this is where things went wrong, as I seem to have lost all my archived 2025 emails,.. I say somewhere,.. as I don't seem to be able to find them, I have used the 'find' command to locate anything with 2025 in the file name,.. but without success. At the moment I have a multi-structured 'local folder' entry, but nothing with 2025 in? I anyone able to shed some light on what I may have done wrong Many tx

Hi I'm using two PC's, both have Thunderbird on. However, PC1 has version 128.10.2 esr PC2 has version 138.0.2 (64 bit)

Does that matter? What is the difference?

I am running Version 128.10.1esr on Ubuntu Mate for RPI 5, do I need to change anything to update Thunderbird software channel, or I simply uninstall and reinstall Thunderbird will do, I don't need to backup.

Kind Regards Esme

Hi there,

I'm using Thunderbird on Linux and would like to know if there is a timeline for when the official Flatpak will be switched from ESR to Release Channel. There was a mention in an article on the Thunderbird blog (https://blog.thunderbird.net/2025/03/thunderbird-release-channel-update/) about the release version being available as Flatpak "in the future" but since this was almost three months ago, I was wondering if there is an update regarding this.

I'm aware that I can either install Thunderbird manually or use the beta Flatpak (which already seems to be on release channel) but I would much prefer to use the stable Flatpak.

Thanks!

For a few days a banner persists on the lower left of the message window. It obscures content. ""Upgrade to Thunderbird Release"" I have checked twice to make sure there is no update available. Why does this annoying message persist after I run the update. I have rebooted the application multiple times. I do not want to click "Learn more" on the annoying banner promoting "Get monthly updates. with new features and improvements in the new Thunderbird Release" Is it malware? If the application is up to date why are you forcing me to "Learn more"? This is not a good user experience. My MacBook Air is up to date. Thunderbird release 128.11.1esr

I would like to be able to download thunderbird addons as part of a automated provisioning process using ansible. I am currently unable to download addons due to cloudflare bot protection. Is there an authorized/authenticated means available to achieve this?

Since the Sequoia install on my Mac I have had many issues. Most of them involve getting logged in to sites I use frequently. Yesterday and today I was unable to load the most recent firefox update and then the most recent thunderbird update. The wheel keeps spinning but nothing actually happens.

I am using Thunderbird 115 with macOS 13 (Ventura). When I upgrade to macOS 15 (Sequoia), I assume I will have to update Thunderbird to the latest version (138?). Before upgrading the OS, should I update Thunderbird to version 128 so that, after the OS upgrade, Thunderbird will then be updated from version 128 instead of version 115?

Also, I found this warning (https://support.mozilla.org/en-US/kb/installing-thunderbird-on-mac):

“If you fail to install Thunderbird to the Applications folder, every time Thunderbird starts it will not have remembered your previous session settings - it will ask you to create email accounts, or otherwise indicate that it has no data. You must drag the Thunderbird dmg file/icon to the Applications folder.”

I am currently running Thunderbird from a subfolder in /Applications. Do I have to move it before updating?

Thank you.

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.

The TB Solutions only provide information for a tar "bz2" file. I downloaded a "xz" file (thunderbird-140.0.tar.xz), how do I install this?

Thanks for any help or solution.

I wish to update my current version of 128.12.0esr within my Ubuntu 24.04.2 LTS OS.

This latest version of Thunderbird has all sorts of bugs. I can't open or view email, can't save drafts & send messages (get errors: failed to save drafts & send message). I constantly reinstall the app: works fine at 1st; but then the same bugs keep resurfacing. Is there a way to go back to the earlier release version? Thunderbird was working fine before this latest version was installed.

I cannot download thunderbird. I already donated money and the donate screen keeps blocking my install. I CAN NO LONGER RECEIVE EMAIL SO YOU WILL NEED TO TEXT YOUR REPLY TO <redacted>
