Problem noticed 4/28/26, am using ExpressVPN and Malwarebytes. I tuned off the vpn = no difference. I do not want to turn off my anti virus. ISP = Zianet. TBird V 149.0.2 as of my previous problem restoring TTrash. I do not know if there is a new version since I cannot open

First, let me describe the configuration I have been using successfully for two decades -

I am on the latest release channel release with a POP3 configuration.

I keep the message store on my file server and have Tbird installed on it and my laptop. The file server is a Win 11 machine as is my laptop. Each machine points to the message store (including the config file) on the file server.

Of late, every time I try to use Tbird on the file server, I get "You have launched an older version" message. So far reinstalling and pointing to the existing message store works.

But I am getting bored with having to reinstall every time, and I suspect this will eventually break completely.

Is there a way to stabilize this?

Thanks Jonathan

I'm currently running Thunderbird 140.9.1esr and it shows an update available to version 140.10.0esr. However, when I click on the update button, it shows "downloading" but it stays at 0 bytes and will not download the update. All previous updates to my current version automatically downloaded and installed after I clicked on the update button. How do I fix this or is there a problem with 140.10.0esr? Thank you!

It appears that Thunderbird was very recently changed. I was very happy with the version I was using before the change. How can I get my old version back?

I don't know what version that was. I have used Thunderbird for a while. Does that imply that the previous version was 149.01? Or was it 148.01?

I had been using Thunderbird on a linux computer (ubuntu). I am now using it on a windows machine (temporarily, I hope). Could that be the reason I see a dramatic difference?

Thank you.

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

Auf meinem Laptop mit Windows 11 Home öffnet Thunderbird sich und der Bildschirm "Willkommen bei der Freiheit" erscheint. Dieser Bildschirm lässt sich nicht schließen. Es gibt keinen X Button. Ich kann lediglich auf links wie Mitmachen, Spenden, etc. klicken, aber meine E-Mails nicht sehen. Das Problem besteht seit gestern, ein Update habe ich am 27.03. gemacht.

In the Thunderbird newsgroup (which I will not name here), one person said the following:

"TB 149.0 (64 bit) tells me I can update to 149.0.1 but when I go to the "What's New" site, the info on the announcement page is "CHANGED There are no Thunderbird changes requiring release notes in this release" and nothing new is mentioned either. Why the release? What's different? Why the secret?

I too would appreciate knowing why this happened.

I can't find a contact person, and the Mozilla account name has been changed. Is that normal?

Thank you for your help and answers. I hope I can continue writing to you in German as well?

Question: There was a number after my email address, like "Email" and "1954." Who is that? Is that normal?

Question: Thunderbird Developer Toolbox: Can you see my emails in the program?

Question: Are there any German-speaking Thunderbird users left?

Questions: Thunderbird Portable The archive option isn't updating? How long does the backup take?

Different Thunderbird versions display a programmed year date in the archive option. For example, 2021 in one program and 2024 in another. Is that normal? I can't change anything.

It's as if it's accessing some kind of backup and maybe even sharing it, and I don't know what's correct.

Question:

Update Channel Ellipse Update Channel esr. Previously, there were different channels. Isn't another channel better? I've read that it's more stable than switching. Is that true? Information regarding the question below?

After running an update, when launching Thunderbird it says "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?". Rebooting does nothing, I'm prompted with the same message. Tried re-installing the latest version - it gives me the same error message before re-installying, and also un-installing the version I have on my PC - it also prompts me to restart to finish the earlier upgrade.

Twice in one week a complete wipeout of all my accounts and emails, hours spent restoring my information after the first update, now a second one, do you do not care about the users of this product? and you wonder why you don't get donations when you wipe out everything and give NO instructions on how to avoid all this. Where is the version hidden?

The user who found she could not run the new version was the user who installed the update. She returned to the previous version (which runs OK). As before the update, server access was via Pop. However her Sent and Local Folders did not appear at all on return to the earlier version and her Inbox now contained only a few recent emails from this year and emails from several earlier years was missing. She set up a second account using Imap in order to be able to retrieve all her incoming mail from the Virgin server but is still without sent mail and her local folders.

Is there any way to retrieve the missing data and to combine the IMap and Pop accounts into one?

Ich habe ein Update von meinem Tunderbird Konto gemacht. Meine Software ist Windows 10. nun habe ich keineUnterlagen mehr. Was soll ich tun. bitte um Hilfe. Bin bereits82 Jahre alt und habe keine Hilfe.

Hi, I will just open with a notice to Mozilla - I would happily donate to your work IF..... There are a number of irritating features I encounter using Thunderbird but one of the most infuriating is that when updating, any message tabs that were previously open disappear - when surely it must be possible to locate these in a straightforward data file somewhere - ready to populate automatically or even manually would be appreciated? At least, Firefox, after a bit of searching does keep a list of history..... but who wants to open ALL tabs in any period of history regardless of whether they were open when the update occurred.

Colours of anything and everything could be varied to speed up and simplify use? Server settings are all over the place... taking longer to enter/locate and edit than they ever should..... seeing a list of every setting inside a postage-stamp box without being able to even see much of it - after all these years surely you can over-rule Microsoft? Avoid kowtowing to monopolies!

I must get on with proper work so will stop moaning now... but my first line stands - get things professional and smoother with greatly increased options and I'll (probably like many others) be keen to give financial support!

Warmest wishes, Tom

I've been afraid to upgrade T-bird since 102 because last time, it changed the look and feel of my program. Honestly, I had a devil of a time getting panes reconfigured back to looking how I had it. After that, I turned off updating.

If it matters, I've got Classic view enabled (along with folder and message panes).

So to my question, if I update, will everything stay the same. Honestly, if it's going to change again, then I may stick with what's working. A friend is suggesting Betterbird, but I may just bite bullet and go to Gmail.

Does what I am asking make sense? I just don't want the layout to change based on what someone – who isn't me – thinks is better because I 'like' how I have it configured.

Many thanks!

So, updated from 147.x to 148.0 this morning 9Win 11 Pro), and didn't take me long to realize that the upgrade nukes Google calendaring using Provider. With 148, if I look at the calendar, 100% of the entires are 'missing'.

If I (i) unsubscribe from the calendars, (ii) uninstall Google Provider, (iii) re0install Provider and re-authenticate, (iv) re-subscribe, then calendar entries are shown.

But...if I turn off TB, and turn it back on again, calendar entries disappear.

Note this is only an issue with 148.0. On my other machines (which largely run 140.x), not a problem.
