Thunderbird Community Forum

I am currently using Thunderbird version 140.10.2 esr. (32bit) I understand that to latest version is 150. I also understand that, from version 145, Microsoft Exchange accounts are supported natively by Thunderbird.

I am using a generic desktop PC running Windows 10 Pro (22H2)

I am having difficulties with an Exchange account using the OWL add on.

I would like to upgrade my Thunderbird to the latest version and use the native support for Exchange accounts. I would also, if possible, like to upgrade to a 64bit version.

When I follow the instructions (Help/Update Thunderbird) the pop up reports that 'Thunderbird is up to date'.

I can't see a way forward at present, can someone assist please.

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?

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!

Now I have Tbird running on my Android with all my email accounts in it. However; my PC version (Win 11) is like a first install. Blank slate. It asks about some "Hub" thing and I don't understand exactly what it is asking for. Outlook name and password? Mozilla account name and password? Some other username and password? Can't transfer anything from mobile to PC (not good). Any way to fix this? Don't tell me I might have to go back to Outlook...

I see that MS Exchange server support is available in Thunderbird version 145 and above. I have a Linux Mint PC which is version 140 which when I try to upgrade I'm told I'm on the latest version. Is there a version 145 and above for Mint and if so how do I upgrade it??

Thank you

got an update for thunderbird and ended up with a different program. the old one would boot into inbox could start with a new email and send right away. After the update it boots into address book can't find anything and want the old program back. Its not supposed to look like a browser with tabs the old one I could run from inbox knew where everything was, the new one looks like it was written by Microsoft. Two pounds of crap in a one pound bag. tell me from what you see how to find the app menu and version

Every time I let Thunderbird update, the format changes to a previous format and my emails and folders are gone.

Having to call my contacts to have them send these receipts again is frustrating. Setting up new folders AGAIN is frustrating.

I have thought of contributing to you, but this behavior is beyond infuriating and costs me hours and hours of time to fix.

How can I get consistency? How can I retrieve what is lost? The only thing I know to do is to STOP letting you update my program.

Not a happy camper.

Very simply as per the summary, every time I hit restart to update and then do another Help/About it ends up back with exactly the same result every time and while I downloaded the latest version available for download and installed it, it does not come up with 150.0.1 but the same as above.

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

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?
