Hi. Since the last 2 updates, my Bell sympatico email through T-bird cannot SEND anymore emails (No errors are given but the email never comes through). I can receive emails without issue and when I use another tool (like Outlook or go directly through my browser, the sympatico emails come through) I attached the settings for the SMTP in a screenshot if that could help.

Any idea how to fix this?

Tx, Robert Z.

Hi

I'm using Thunderbird 140.5 on a desktop Mac running Sequoia 15.7.2

In Local Folders, my subfolders have subfolders. In both levels of subfolders, Thunderbird has spontaneously started disordering both newly created subfolders, and folders which I move from one subfolder to another using right click 'Move To'

Up until ten days ago, all folders whether new or moved, were listed alphabetically. Now, day by day, the disordering is getting worse and as someone with ongoing conversations with hundreds of clients, it is becoming impossible to work when I have to give so much time to slowly scanning through every folder looking for the relevant subfolder.

I don't know why I can't update this version, but I tried installing the newest version available (145) and used the 'reset folder option' which did not work either.

Also, setting up a whole new account instead of upgrading my existing account is a colossal faff and I'd rather not have to!

Aside from manually reordering (also a colossal faff), can anyone suggest something I might be missing in stopping this happening?

Thunderbird says I'm on an esr channel, if that helps

Thanks

With 03.04.2026 they began to notice that the attached emails in eml format (the attached emails have attached documents, mostly pdf) sent from yandex mail stopped opening. Everything used to open well. Eml also does not save to disk. If you send the same files via Gmail, everything opens. Program version 150.0.1

Other than being slow to download my emails now for a few months, TB was performing well until a week or so ago. Now it also won't open the downloaded email when I click on it and the TB freezes up so I can't close it out. I have tried restarting computer multiple times and it works for one or two emails that I can open and then starts freezing up again. Makes using it almost impossible. I have security Windows 11 Defender only and have had it the entire time when it also worked well.

Running Thunderbird 128.14.0esr (64-bit) via 64 bit Win11 Pro v. 25H2 on a Dell Inspiron 16 plus, Core i7-12700H @ 2.3 GHz, 24 MB cache, 40 Gb RAM, 877 Gb free on a 1.8 Tb Crucial T710 NVMe SSD drive. Integrated Intel Iris Xe graphics using 20 Gb shared RAM.

I have 5 email accounts (AOL = Yahoo, Yahoo, GMail, Verizon = Yahoo & MSN) each with a distinct IMAP server description. I also had my daughter's AOL account in the same TB profile.

On 5/9/2026, I foolishly entered my credentials in an AOL request for verification of her account (to allow TB access). As result, my jawarters@aol.com account and her jmwarters@aol.com account somehow became linked. Her email account in TB now contained only messages which were duplicated in my email account.

I deleted her existing jmwarters@aol.com mailbox and attempted to recreate it in Account Settings. Despite entering distinct IMAP settings (user name = jawarters@aol.com, imap.aol.com, port 993 and user name = jmwarters@aol.com, imap.aol.com, port 993) and having distinct SMTP settings with the user name in the Description, the recreated account again downloaded my emails into her TB account. The same happened when I opened TB on my desktop.

Interestingly, TB for Android v. 18 kept both accounts separate. I attach a copy of the TB Android k9s settings file which shows the same IMAP and SMTP settings as the laptop / desktop TB.

Help solve my self-imposed problem! Jim W

No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?

Everything has been fine for several years but this morning I now get error: TB could not connect to server mail.twc.com, the connection was refused. Spectrum says everything is good on their end. What do I have to do to "fix" Thunderbird? I can't send or receive any emails from 5 accounts with Spectrum and the emails are there when I log in at WebmailSpectrum.net..

Version 140.10.2esr | Released May 8, 2026 I get this message every time: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.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.

Thank you, George Correia

Thunderbird keeps opening a Google authentication window, asking which account to use. I have two gmail accounts (both of which work just fine), and another google account that I manage a calendar for (it works fine as well). How do I work out which account is seeking authentication?

I have been using Thunderbird for a very long time. Today is the first time I have seen this happen.

In the column on my left side that has my account and folders for those accounts it is showing 5 in my junk account. But in the preview window to the right of that column there is nothing showing as far as any entries as junk mail. It is completely blank. What do I need to do to clear this 5 from the left column Junk folder??

I have tried resetting the machine and that did not work. I even went into the webmail site for my email provider and there is no junk email showing there at all so as far as my email provider goes, it looks like everything is working there.

Trying to remove Thunderbird. Windows add or remove programs isn't working. I'm trying Program Install and Uninstall Troubleshooter, which needs Thunderbird's product code.

I can't find it on the site. Can someone give me a hand?

I'm getting "Thunderbird can't connect to the server" message, so I can't download messages. However, a message or two will finally download 1-2 hours later.

Same problem on 2 laptops, both running Windows 11. But I know my emails are coming in as I can view them via Spectrum webmail. So the problem isn't the Spectrum servers.

I've logged out and back into Thunderbird, and have re-booted my laptops. No luck. What to do?

Also, is there a place to report problems directly to Thunderbird?

Thanks for any help.

Firefox 150.0.2 (64-bit)

After rebooting my computer, Firefox hangs for a very long time trying to access common websites such as cnn.com, facebook.com, mozilla.org and apnews.com. A google search will work, but the links (including the google control links at the top such "AI Mode All ... More Tools" are not active. Often there is a message at the botton of the screen indicating some external site is being accessed. During this time, other sites that do not have external references will quickly open in other tabs (bwi.com is a good example). After about 20 minutes, everything magically starts working correctly. Disabling "secure DNS" does not correct this problem.

I downloaded Thunderbird into a new computer and there are a lot less emails than on the old computer. I cannot find a setting to download the rest of the emails. Can you please help. Please send me an email telling me if I can download the rest of them.

After installing Firefox 150, clicking on a window for a different application does not make that application active. Firefox is not letting me leave! I can switch by going to the sidebar and choosing a different application. None of the other applications exhibit this behavior. MacOS 26.3.1

My microphone does not work properly in Firefox, it sounds periodically really low and that doesnt depend on my mic settings. It seems like that is Automatic Gain Control or something like that and idk how to disable it. On screenshot im just speaking as usual but the browser lowers the volume -_-

Firefox kept losing all of my saved bookmarks and passwords. Each time it updated everything would disappear. I went to the folders where the bookmarks and passwords are stored and the profiles were there but Firefox did not list them when I searched (about:profiles). Tried numerous times to move the files to the current folder but the program still could not see them. Tried copying, moving, changing names of files, etc. Finally uninstalled firefox and attempted a new installation but it will not even open because it says it can't find profiles even though there are profiles in the profile folder. Now what do I do?
