Thunderbird has suddenly decided no matter what I do it is not responding. I cannot access my emails or do anything else. I became so desperate I decided to use Eudora BETA instead but that is just as bad. I have removed both programs from my computer but when I download and install Thunderbird it opens with all my old information but still I just get the message Not Responding (there must be something somewhere that has not totally removed the program I would think for this to keep occuring??). How do I fix this problem as it has become beyond frustrating.

About 24 hours ago Thunderbird suddenly stopped downloading my emails. I rebooted a few times and still nothing. I went to email web version and my emails were coming in fine there. I read a bunch of articles here and went ahead and deleted my email account within Thunderbird with the intention to add it back in. Then I had password issues and had to call the email provider to reset my password. Now my password is fine, but when I go to add back in my account Thunderbird says it cannot verify the password. I went through several tests with the email provider's support and since I could log in everywhere I needed to with my password, and the only place it will not work is on Thunderbird itself, she concluded that I need to get support from Thunderbird as that is where the problem lies.

Of course there is no support for Thunderbird....and I am so frustrated at this point! I have been using Thunderbird forever! at least ten years or more...and this has never happened before. I really, really really don't want to switch my email client but I cannot seem to get this one to work all of a sudden anymore and if I cannot get it to work I need to find something that does. Can anyone help please?

My eyesight means the (stock) small font size of Thunderbird renders it unusable without using the excellent Font and Theme Size Changer (FTSC) .

Following the auto update to TB v 60.2.1, FTSC is disabled by Thunderbird giving me the message "...This add on is disabled as it's not compatible with TB 60.2.1..."

Is there any way I can roll back to the previous version of TB and then stop TB from updating.

Started getting error April 10. I have SSL/TLS and Oauth2 set for Thunderbird account server and smtp. Looked thru lots of web messages - no joy. Via web browser I can connect to my Yahoo email without issue. My gmail account on Thunderbird still works fine (with its unique third party password). I am on current Thunderbird release 115.9.0 (64 bit). I disabled the only add-on that Thunderbird was using. Windows 11 Pro which is up to date. Plenty of open disk space. Have rebooted my PC multiple times.

Looking for suggestions Thanks Bob

My ISP, Cox, sent me a message that I have to change my POP server settings from:

port 110, Connection security: None, and Authentication method: Password, transmitted insecurely

to:

port 995, Connection security: SSL/TLS, and Authentication method: normal password

When I do this Thunderbird will not retrieve any new messages. The same changes work ok on two android devices, so I can see from them that there are new emails for Thunderbird to get, it's just not getting them. I tried changing one of my accounts back to the port 110 settings and that account now works again.

I tried contacting Cox about it but they stated that they don't support Thunderbird and referred me here.

I'm on Thunderbird 52.5.2 32 bit.

My default font is Calibri. However when writing messages the font often changes to Times New Roman. This happens especially after indenting a paragraph. It also often happens right from the start when replying to emails.

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

Folks:

I am running 64-bit Windows 10 Pro ,version 1511. I had been running Thunderbird 52.9.1 without any problems whatsoever. A few days ago, Thunderbird upgraded to 60.3.1. Thunderbird became unstable and unusable immediately upon start. Taskbar and Process Explorer showed that the program was running, but the window would not stay open or even stay stable.

I was able to use System Restore to revert to the previous version of Thunderbird, and although the calendar functionality is gone, it seems to work fine.

Any help you can provide would be greatly appreciated.

Thanks!

Attempting to send e-mail via Thunderbird. When hit send, window saying Login to server mail.uwclub.net failed enter new password, enter password in window saying SMTP password required. Enter password then back to first message window. Have contacted tech at Utility Warehouse who says can't replicate problem on his system. Considers it may be password problem, clash with Thunderbird.

I get the following error for some emails: An error occurred during a connection to www.xxxx.com:443 Cannot communicate securely with peer: no common encryption algorithm (s) (Error code: ssl_error_no_cypher_overlap)

Could anyone offer a tip on how to remedy this?

Yesterday Thunderbird wouldn't open on my laptop. I rebooted the computer and still couldn't get it to open. I started to get a crash report window when I tried. I used MozBackup to save my emails today. So, should I uninstall and reinstall Thunderbird? If so, could you let me know how to do that? Also, do you think the backup I made today is corrupted? I backed up a couple of weeks ago so I won't be missing too much if I have to restore the earlier backup. Thanks for your help! -Jeffer

Help?

This is a problem on my father's computer. I'm a computer tech, he is not. On MY computer, I haven't had this problem with Thunderbird 60, even though I also use Gmail (as well as other e-mail providers).

Immediately after Thunderbird updated itself to version 60, it would crash within 1-2 seconds of Thunderbird starting.

Troubleshooting: - Rebooted computer several times. - Starting Thunderbird in Safe Mode.

Still crashes.

I created a new Thunderbird Profile and set up his Gmail address using OAuth2. Successfully receiving e-mails with no crashes.

I exported his address books and calendars from the old profile, and imported into the new profile. Copied the Local Folders files manually from the old profile to the new. Got all the Thunderbird settings the way he likes. No crashes.

An hour later, Thunderbird starts crashing again. Now it only crashes when a new e-mail comes in.

Troubleshooting: - Rebooted computer. - Starting Thunderbird in Safe Mode. - Disabled filters.

Still crashing.

Submitted Thunderbird Crash Report with details and my father's e-mail address, which I will not put here in this public forum.

Windows 10, 64 bit (lots of memory and lots of hard drive space) Thunderbird 60.3.0 E-mail provider: Gmail

It's been nearly a year I think. A good six months, at any rate.

I filed a case on it about 3 months ago, but the "My Questions" list doesn't show it.

At the time, I was treated to an entire digest of how I was supposed to examine 100 tasks going on in my system to see if one of them was causing memory problems... As if!

But here's the thing:

  1. NO OTHER PROGRAM ON MY SYSTEM experiences the kind of stalls that Tbird sees,
      and they are all laboring under the same constraints.

  2. TBIRD STALLS IN THE MIDDLE OF WRITING A MESSAGE -- TWO OR THREE TIMES, in some cases.
      That is a simple inability to grasp the concept of MULTI-TASKING in software.
      Background processes can stall all they want. Foreground processes should NEVER see them.

  3. TBIRD DOES NOT DOWNLOAD MESSAGES UNLESS AND UNTIL I AM USING IT.
      I can have it open on the desktop for as long as I want. But once I click in it, THEN I see the
      "downloading messages" alert. That too is a SIMPLE FAILURE TO UNDERSTAND MULTI-TASKING.
      If the program is running, it should have been downloading things in the background--not
      wait until I am attempting to use it to DO something.

 4. TBIRD SUPPORT APPARENTLY BELIEVES IT IS BEST TO BLAME THE USER.
     Again, a simple failure to understand the concept of multi-tasking is the root cause of the 
     problems I have been experiencing. But reporting the issue did no good whatsoever. 
     Instead, I was supposed to spend a day diagnosing memory issues -- "issues" that DO NOT
     AFFECT ANY OTHER PROGRAM on my computer.

So I gave up. I moved to Outlook. Sure enough, no stalls. Big relief. I have my inbox set up, and just imported my contacts. That just leaves a few years' worth of old messages I wish I could transfer. So I'll keep TBird installed, just to access those old messages, when I need them.

But as for daily use, no. It's history. I write this message to explain why, in hopes that someone will learn from it.

Dear Friends,

I can Email my wife at [elainefraser43@hotmail.co.uk] from my Gmail account:

I can Email myself [ralphfraser1@talktalk.net], which is on "Thunderbird", from her Hotmail account:

BUT, when I attempt to Email HER via "Thunderbird" my Emails are rejected, and I get the above-mentioned Unknown address error 550-"SC-002 [COLO-MC3-F42] failure message!!

This is all WELL above my head!!

Please can you explain what needs to be done here???

Regards,

Ralph Fraser

I have a bunch of IMAP accounts, most gmail, but one at alumni.caltech.edu. At the end I copy-pasted the start of Troubleshooting Information. All have been working fine with Thunderbird for years.

Today, for every account, if I click "Get Messages" I see "<account-name>: Connected to <hostname>..." at the lower-left in the status line, but it never completes or times out, and I don't get any new messages, even though I can login to webmail and see that there are new messages.

I've quit and restarted Thundbird, I've paused my Eset Smart Security firewall, and I've rebooted.

I tried turning on Thunderbird logging in an elevated cmd window with: C:\WINDOWS\system32>set NSPR_LOG_FILE=%HOMEDRIVE%%HOMEPATH%\Desktop\tbird_log.txt C:\WINDOWS\system32>set NSPR_LOG_MODULES=POP3:5,IMAP:5,SMTP:5 C:\WINDOWS\system32>start thunderbird

Thunderbird eventually went into offline mode and I exited, but I don't know how to read the log file properly.

This is on Windows 10 Home. I did get a significant Windows Update overnight: Version 1709 and an update to it, KB40058043. I noticed this morning that I had a Windows Mail app in my taskbar (which I removed). I'll also say that my wife's PC got the same Windows update, and her Thunderbird client is working fine.

I'm out of ideas how to fix or further analyze this - can someone look at the log file? Since it contains email addresses I don't want to try posting it.

Hey folks, I'm trying to copy some large emails, they have some photos as attachments, from a POP3 account I have on thunderbird to a new IMAP account I set up, which is my Gmail account.

I've tried even just a handful of mails to transfer over, but they seem to be failing after attempting to transfer these larger mails.

Is there any way to do this differently or allow more time for Gmail to accept them so they copy over without any problems?

Any help would be great!

A couple of days ago Thunderbird started flashing views. It went from the vertical view I've always used to one where it only shows the folders then emails, sender, size, and date spread horizontally across the whole widescreen. It was unresponsive and used a lot of cpu when doing this. I could not click on an email and read it as there is on section to do that anymore. I found I could right click on an email and after many seconds the right click menu would appear and I could choose "open in new window" and access it that way. I've tried restarting in safe mode and uninstalling and reinstalling Thunderbird with no effect. It's now stable with the whole screen folder, email list shown. The only way to read emails is in a new window or tab. The layout options under view do not work. The included screenshot is the only view I now have. Any help, ideas would be greatly appreciated. Thanks, Len

Ok, last week I migrated my Verizon Email to the new AOL/Verizon email set up. All went smoothly. I was sending and receiving no problem. All of a sudden, I am not sending or receiving. I can get mail from the AOL.Mail site, but can not get from Thunderbird. I have a G.mail Acct using Thunderbird and it works fine. Any idea why the new Verizon/Aol might be stumbling over Thunderbird? When I try to get mail it just hangs, when i try to send i instantly get this message...Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.verizon.net was lost in the middle of the transaction. Try again.

My mail email account is a hotmail one, however I have two hotmail accounts, a Yahoo, and a Gmail all conected to Thunderbird and all having the same issue.

I can see that I have new mail. I double click to open it, a new tab opens. It sits blank. The email ether never loads or takes far to long and I get it quicker signing in to live mail though firefox. Any suggestions welcome :)

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga
