Good day, thank you in advance for your help.

I have two questions: 1. Which Thunderbird version is better than ESR? Could you share your opinion?

It's faster and it applies all changes more quickly, that's how it seems right now.

If there are still 32-bit and 64-bit versions available simultaneously, I'll test it sometime. I have no idea what kind of channel that would be.

Problem question:

In Thunderbird 64-bit POP3, the font changes to blue for every second email, including in replies. Can you tell me how to display every email in black? Only the second email in the inbox is displayed in blue, so the text isn't blue when receiving emails. When composing, everything looks black. What do I need to change?

Question 2: Regardless of whether it's 32-bit, 64-bit, or any channel, I see updates to the latest version, and in the program itself, there's an option to view older updates, but everything is white. I only see white and nothing else. Is this intentional? I can't see the update, but it's still current?

``` Thanks for the information

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?

Running into a strange issue where the welcome message page does not go away when clicking between messages. I already attempted to remove the message pane all together. (F8) but nothing seems to make it go away. Usually upon launching Thunderbird it will show the welcome message but will go away when navigating between messages.

After updating my Thunderbird mail application from version 128 to 140, the shortcut icon for composing a message is no longer responsive and I cannot create a new message from it. I can no longer create a new message without right-clicking on a sent email and using “Edit as New Message (E)”. How can I get back to being able to create a message from the message creation shortcut?

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.

I am on release 140.12.1 esr and there appears to be no new updates available. If so, what release should I be on and can I just download and install to get back on the latest release

I have been trying to stay on releases and was told to upgrade to 115.10.1. So I did that and was told to go to 115.18.0 and it was not noted as esr. So I did and was immediately told to go to 128.8.1 esr. I was not on the esr channel and do not want/need to be on esr. about:config has been changed to esr channel from release w/o my ok - the least I'd expect is a warning. Release 115.x.x has betas and releases more than I had seen previously - aboutr 25-26. It looks like nothing but betas from 116 to 128 and a lot of what look like releases from x.0 to x.10.2 which is new to me. What is the rational behind all these versions and why there is not a simple center of how to use this info? I remember when way back, tbird had issues but they were manageable.

Updating on June 20, the existing Thunderbird version in a flash of a second was replaced by a new blank one. All files and settings were lost. I needed an expert who (at cost of course!) managed to roll back the program with all files and settings as they were. This was a disaster, how can such effect happen? Right now I do not trust the updates anymore and will not implement new updates.

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

This morning Thunderbird asked me to update which I duly did. Once done all messages started disappearing from inbox. Eventually I found them and moved them back to inbox only for it to happen again

Have now tried 3 times, same result, every single email from Inbox keeps being moved to deleted in Local Folders

All new emails that have come in since appear for a micro second in Inbox before being moved to Deleted

This is obviously not a great situation to put it mildly and as it has never happened before and started straight after this morning's update I can only assume that the update is to blame

Any help would be greatly appreciated

Hello,

I'm confused and slightly concerned.

Through no deliberate action by me, Thunderbird DOWNGRADED itself from the May 2026 standard release version to an AUGUST 2025 ESR(Extended Support Release) version.

UPDATE: the next application restart brought the ESR version up to date, but why was I forced onto the ESR version?!

What could have pissibly triggered this? I don't want or need ESR, and without knowing the cause, I have e no guarantee it won't happen again. Worst if all, everywhere I look, there is zero explanation for this. It appears to be fairly unprecedented.

My original installer for 102.15.1 was downloaded from the official Thunderbird site in 2025.

The sequence of events:

• I've had Thunderbird version 102.15.1 installed for awhile, but wasn't using it.
• Ysterday I opened it and connected an account.
• Today I noticed it hadn't auto-updated, so I went into the settings and clicked on the 'check for updates'.
• this brought it up to v115.10.1.
• Its success was demonstrated by me being sent to this URL after it opened: https://www.thunderbird.net/en-US/thu.../?locale=en-US&version=115.10.1&channel=release&oldversion=102.15.1(https://www.thunderbird.net/en-US/thunderbird/115.0/whatsnew/?locale=en-US&version=115.10.1&channel=release&oldversion=102.15.1)
• An hour later, I closed Thunderbird completely hoping it would fix a sync that appeared 'stuck'.
• When I re-opened Thunderbird, I saw the small "updating" window. It was pretty surprising since I had *just* updated.
• After Thunderbird opens, after this additional "update", the URL that I'm sent to is this: https://www.thunderbird.net/en-US/thu.../?locale=en-US&version=128.14.0&channel=esr&oldversion=115.18.0(https://www.thunderbird.net/en-US/thunderbird/128.0/whatsnew/?locale=en-US&version=128.14.0&channel=esr&oldversion=115.18.0)
• Thunderbird changed to a year old ESR version!

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.
