I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

When I open Thunderbird (Mozilla), my files are not current. In other words, the most recent emails, probably since the last time I used Thunderbird, in my file folders are missing. I have tried changing the server settings but I think they are correct. Please be patient with me, I am unfamiliar with all the terminology, etc. Also, when I first enter Thunderbird, it does not recognize my password. A window opens with the message "Login to server imap.postoffice.net with username john.fn@usa.net failed." That message also appears when I click on Get Messages. Thanks for any help.

I can not access for days my bank account at truist.com. It shows it is loading but never does. I CAN access from any other browser want to use! Truist says it is a Firefox browser issue.

As of yesterday my Thunderbird account vanished, screen asking to set up an account. I am too old to be an IT expert, and I need detailed step by step guidance how to restore that account, full of Inbox emails and folders/subfolders. If it matters (depending on requirements?), my address is @verizon.net - which is pop3 but I have no problem opening the same emails on different devices, as if it were imap (verizon taken over by aol). Pain in the neck, hope to get help.

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?

To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

Good morning, I had asked a question early on Saturday, but was unavailable the rest of the weekend so just now responding to associate Corey Bryan's answer. I had gotten a message that I am using an unsupported version and they recommend downloading the latest stable version.

He said it appears that I'm on the "Release" channel and most likely want to be on the ESR channel. I also mentioned that I am a cave-man when it comes to anything computer and am very skittish about making any changes as I don't how to straighten out any errors that might occur.

He asked me where I installed Thunderbird from and the answer is that I don't know. It was an IT guy that did it many years ago.

So I guess my questions are, if I've been using this version for years, do I need to or should I update it? If so, if I click on the latest stable version of Thunderbird, will that change anything on my computer, aside from getting the newer version of T-Bird? And will my e-mails in Thunderbird look any different?

Thanks very much for the help. Tony

Hi All,

I would like the content area of my tabs moved up so that the box is filled with the actual tab color, without the white background, and also the text will be vertically centered. Right now, the text is dropping too close to the bottom of the tab.

Had this looking very nice in FF 88 with the same code, as you can see in the attached images, but it seems to render differently in FF 115 ESR and FF 125.

Below is some code I used to style the tabs, but the problem exists without this code as well.

I've also included some "tabs on bottom" code I'm using as well at the very bottom.

Would sure like to get those Classic Toolbar Buttons working again too (shown in the second image), but that will be a later request :)

Any help is appreciated.

Thanks!

Tonight I accidentally mistyped my password upon starting Thunderbird, so I chose "enter new password" and retyped it correctly. But now it won't download my mail, and I can't find any way to try entering the password again. (My password is not saved.) When I click "Get messages" the blue progress bar flickers at the bottom of the screen briefly but the Activity Manager remains blank. No mail is downloaded and there are no progress messages. There is also a small "null" note at bottom left, not sure whether that's related.

I have tried restarting Thunderbird several times, and restarting my computer entirely. No difference. I went into Settings / Privacy and Security and confirmed that there is no password saved. None of the settings have been changed. But I'm not getting an error message when I try to download mail, it's not doing anything at all (aside from the brief flicker of the progress bar).

I tried sending a test message and got the error "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.theworld.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." But none of my settings have changed. I can access my mail via web server so there isn't a problem with the ISP. But answering mail that way is really clumsy and time-consuming. I need my Thunderbird!

I am using Thunderbird 102.12.0 with Windows 10 Pro. I have been a happy Thunderbird user for many years (since 2015 I think) and have never encountered this problem before. I really hope you can tell me how to solve it, I am aware of several time-sensitive messages in my mailbox and I can't download anything. Thanks very much for your time!

I have a new laptop and did a backup of my files on the older laptop (Windows Home) and restored them to the new laptop (Windows Pro). Then I installed Thunderbird on the new laptop and I already had e-mails on it. But there are thousands of e-mails in the wrong folders.

The Windows Home has Thunderbird 128.10.oesr (32 bit) and the Windows Pro laptop has Thunderbird 128.9.2esr (64 bit). What should I do? Should I uninstall Thunderbird on the new laptop? Then what?

I need to do something with a profile folder, right? But what?

Please help.

It's a mess right now.

Hi, In TB 102 the menu toolbar was still above the button toolbar, if I am not mistaken. In TB 115 this seems to have changed... I could not find a way to customize it back as it was. Pointers anyone ? Thank you.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

I have no idea what is happening... But after restarting, clearing my cache, making sure I have data and it is working for other apps... Still no results.

No matter what, whether I try to type in a URL, click on a link in the google app, or refresh a page I already have open, the app doesn't even attempt to load a page or throw up an error. Just a blank background, no loading bar, no error messages, and no redirects...

FF for Android Version 112.2.0 Build #2015946691

Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

Last night I created a new profile in an attempt to fix a problem with downloading mail. (It turned out to be on the ISP's end.) Tonight I briefly opened two copies of Thunderbird, one with the old/original profile and one with the new profile, to make sure the download would work. I was able to download my new mail to the original profile, so I moved last night's mail from the new inbox to my original inbox in the new profile, and then deleted the new profile since I don't need it. But now the past six months' worth of mail is missing from both my inbox and my sent folder! They both jump from June 13 to yesterday. I noticed it when I had the two copies open next to each other (those messages were missing in both copies), but thought maybe it was a merge problem and hoped they would be restored when I deleted the second profile. But they weren't. I absolutely did not delete all those messages and many of them are really important. Where did they go and how can I get them back? Help!!!

p.s. Sadly I haven't backed up in a while... :-(

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick
