I'm getting a "nonoverridable TLS error" message when Thunderbird first opens. Also, new emails won't download into my IMAP account. I've tried adjusting the incoming and outgoing server port settings and even turning off the antivirus and phishing email scanners. Nothing works. It's now 1:59 PM on a Thursday afternoon and I've received no new emails since 11:20 AM. Please give me security settings that will work.

I'll try again because I would like to continue using Thunderbird. Many times over the past months I have tried to find the answer to this problem. When I click on a link in email it no longer loads my browser. My only option is to right click on the link, copy, then run my browser and paste it. I use Google Chrome, but have tried Edge, Firefox and other browsers and the result is the same. This would suggest the problem is somewhere in my Thunderbird settings. I'm trying to be patient and ask you to be the same. If this problem ever gets solved, I'll begin sending a donation.

   I'm using Chrome on Windows 10 on a desktop computer.  
   My wife also uses Chrome but, on Windows 11 on a desktop computer.  She has no problem with her Thunderbird links.  
   I look forward to any help anyone has to offer.

Hello, I've written to You in below topic: https://support.mozilla.org/en-US/questions/1435807

We've fixed it just as You've instructed us.

But we've still got problem with sending and saving emails. Some messages (not always, just in some periods of time), are not sent and not saved in sent messages. We've had this problem yesterday and now I don't know what has been sent and which were not.

Waiting for your reply. Best regards

Good evening I have been using Thunderbird mail for ages, and now suddenly diverse thing don't work anymore: I can't chose my signatures anymore, the language correction does not work anylonger, and when I print things they come out wrong. Can you please help me fix that? My email is jean-pierre.biber@natcons.ch Kind regards Jean-Pierre Biber

Ever since the past year on the various supernova releases the performance has turned to crap. Very slow, no multitasking performance. I have several e-mail accounts, when downloading from Gmail, my other accounts are non responsive.

And the biggy I cannot select and delete multiple messages. Even a few dozen in spam folder and I get " Not Responding".

The product is wrecked. I never had this much difficulty before. Please own up to the problem and fix it.

Hello there We have read the message. We try to help Follow Up!!

You write that you can no longer send outgoing messages.

Try viewing your outgoing server details in your Thunderbird Software.

These settings are set as they are normally set for use.

After an update, some miscommunication could have arisen, resulting in a situation similar to yours.

Together we can see whether this can be completed so that it works as it should again.

Can you send me a screenshot of your outgoing SMTP server settings for email use? This is probably installed in your Thunderbird software on your desktop.

HELP HELP HELP Duplicates continue to be generated as of latest Thunderbird Version 115.6.1. Final Solution?? Running on my MacOS Ventura 13.6.3 (22G436). Fully updated and kept as my babe!! Same as my Thunderbird. Using the [**Remove duplicates...**] official tool to fix it, but continues to appear always after some time.

Use a lot of dayly maintenance on my mails, creating _new-folders_ continuously and moving mails depending on subjects as needed. Continuously maintaining, Always _empty-trash_ followed immediately by _compact-folders_ Always try to do weekly backups.

Duplicates Still never ended since so long been reported!! Any way to fix the issue once and forever??

Do not need/want to suffer a complete platform crash on my loved mailer. Would be a complete disaster. Obviously I keep on backing up once per week.

Thanks a million if you try to help, and kudos if you solve it. Take care.

the hourglass icon comes on whenever I click anywhere in the inbox, and the program makes me wait too long. This is a new problem with the so-called new thunderbird. It is not an improvement; it was made worse. Please fix this bug. And where it says report a bug, I can't report one.

https://support.mozilla.org/en-US/messages/sent/79157 I inadvertently changed the background of my Thunderbird to black with white text. I have NO idea what I did or how to get it back. I tried this: Menu app icon (3 lines) > Preferences select 'General' Scroll to 'Language & Appearance' click on 'Colours' Text = white Background = Blue uncheck - do not select 'Use System colours' 'Override the colours....' select 'Never' Click on OK

Dear Thunderbird/Mozilla,

I got the "Want Thunderbird On Your Phone?" email what starts with "Did you know that less than 1% of Thunderbird users fund all the work we do? We are completely funded by donations from our global community."

My question is did you know the Thunderbird is getting worse and worse? You would like money from user meanwhile you don't take care what users want?

The new Supernova is a big crap: - multiple folders can't be selected in the same time - Customized icon function also has been removed - TB always makes folders' file corrupted, folders always must be repaired time to time - TB time to time gets stuck during email sending and when I restart TB it removes the email from the Draft so I lose my already written email - TB always turns on f*cking Threads view on all news folder but Thread view is disabled - TB always uses Correspondents column instead of "From", "Recipient" and "Size", I can't set a customized default view. - I always have to restart the TB after a few days because it becomes very slow

Since Supernova has been released we almost each day got calls from our clients and complain about TB why it is getting more useless day by day. So it is a sad story but true.

Thanks, Zsolt

Figure out why links no longer work in Thunderbird. I use the latest version and am running Windows 10 desktop. I've tried Firefox, Edge, Chrome, etc. and the problem exists with all. Therefore it must be a Thunderbird problem. My donations will begin when this is fixed.

Thunderbird crashes regularly. I have determined that it might be due to RAM. When Quickbooks is open, Thunderbird will crash almost all the time. If I close QB, it is fine. I have an HP desktop w/ 8GB ram. What I don't understand is that it started doing this recently, but never used to crash. Is TB using more ram now since the latest releases? Any insight would be appreciated.

Hi,

My Thunderbird auto updated this afternoon to 115.3.1 . Now I am only seeing message headers. The body of the messages has disappeared. I'm not seeing anything on the bottom half of the screen, not even the message tool bar where you can delete, reply, etc..

Strangely -- the very same thing happened to me six months back with a secondary account, but my primary account was unaffected. So I was using the email interface with one email address (same domain name) which worked fine, while the secondary one only showed headers, and not the actual messages.

NOW-- after this download, the secondary email address account is showing both the headers and the messages, while my primary account is only showing the headers.

PLEASE HELP. Posted here six months ago for the previous time but never got any solution to the problem then. Just lived with it, as it was a secondary email address, but I will have to leave Thunderbird if I can't get the primary address showing actual messages soon.

Thanks in advance for your help!

How do I correct my serious error (when tired) in allowing a Thunderbird 'Upgrade' 115.2.2 (32 Bit) Supernova to install on my Laptop (Windows 10 Home, 64 Bit). I failed to read the Release Notes by trusting Mozilla wouldn't issue such a drastic change without Warnings as it was not just an 'Upgrade'! It has screwed up my Set up, Folders etc., completely changed layout, can't find 'Write Message' tab etc. etc . etc.

The previous Thunderbird Version had many problems further introduced by 'Upgrades' but was at least still had continuity with earlier Versions with a functional MMI (man machine interface) instead of all the changes introduced with the 115.2.2, which in my opinion should be withdrawn completely. N.B My experience in Systems Control, as an Air Traffic Control Engineer, we would throw this out as not fit for purpose.

Help Please and explain how can I revert back to an Earlier Version?

HI, I just updated to Supernova 115.3.1. T-Bird no longer downloads any mail from any of my accounts. It acts like it's going to, but nothing happens.

How can I fix this, or how can I downgrade to the last version?

Thank you,

James

tHIS UNTESTED NEW VERSION IS HORRIBLE! IT IS NOT BETTER BUT IS VERY DISRUPTIVE, UNLIKED AND UNWANTED!

WHY VCAN'T YOU RESPECT US WITH A CHOICE?

WHY ARE YOU SO ARROGANT TO THINK YOU KNOW EVERYTHING AND I NEED OR WANT THIS?

WHY DON'T YOU GIVE US A WAY TO GO BACK TO WHAT WAS WORKING?

IT'S AN ABSOLUTE NIGHTMARE. IT IS NOT! EASY OR INTUITIVE TO NAVIGATE.

SO MANY THINGS WRONG, I COULD MAKE A LONG LIST, BUT THIS IS BUSINESS FOR SOME, NOT A TOY TO PLAY WITH!

SOOOO MANY UNNECCARY THINGS ON HERE! THE HEADINGS TAKE UP OVER HALF THE PAGE AND WE CAN ONLY SEE THREE LINES OF MAIL AT A TIME! NO WORD WRAP SO SE CAN'T CORRECT THINGS WE CAN'T SEE.

WHY CAN'T YOU BE DECENT HUMANS AND UNDERSTAND THIS IS NOT RIGHT FOR MANY OF US?

IT'S HORRIBLE! BUT I AM SURE YOU WILL BLAME ME! THIS IS SOOOOOO DISRUPTIVE!

THERE IS NO QUICK VIEW OF MY MAIL LIKE THEIR USED TO BE. I AM NOT PLAYING A GAME OVER HERE.

Thunderbird recently upgraded (?) to Version 15 on my Windows 10 laptop. Since them, when I go to look at the "Trash" folder, I get the message: "Unable to open the summary file for Trash on username@gmail.com. Perhaps there was an error on disk, or the full path is too long." I was able to fix it temporarily by restarting Windows 10, but the error is back a few hours later.
