I'm grateful that I've been able to use Thunderbird for free up until now. I wouldn't mind making a small donation. However, Thunderbird's email service is currently unavailable. Received emails are not displayed in the inbox. All previous history has also been erased. First of all, I would like your cooperation in fixing the current problem and restoring the system to its previous state. I will make a donation as soon as the system is restored. If the system cannot be restored without a donation, you can make a donation first. I look forward to your reply.

"Sending of password for user joebernard@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later"

^^This message comes up every time I try to send an email. It can be received outside of Thunderbird and to other addresses.

When I launched Thunderbird today, it would not connect to one mailserver: imap.mailfence.com. At the same time, Thunderbird said to restart to update to 115.2.2. After updating, it still refuses to connect. There is nothing wrong with Mailfence and I do not find anything wrong with the configuration settings in Thunderbird. I even tried to set up my Mailfence email account again but it failed because it could not connect. Ideas? Thank you.

I get the pop up that includes Add Security Exception

 You are about to override how Thunderbird identifies this site.

Legitimate banks, stores, and other public sites will not ask You to do this. Location:

This site attempts to identify itself with invalid Information. Unknown Identity The certificate is not trusted because it hasn’t been verified as issued by a trusted authority using a secure signature.

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help

My e-mails fail to be delivered to my inbox immediately. They are held up somehow and then suddenly appear days later as a batch of them as though they have been held in a storage box.

When I restart Mozilla Thunderbird, my S/MIME certificate preferences under Account Settings seem to break.

When I initially select a certificate, both the common name/certificate name and the certificate fingerprint appear in the interface (see Working Settings.png). However, after restarting Thunderbird, only the common name/certificate name appears in the interface, and I cannot use S/MIME to sign messages (see Broken Settings.png). When I attempt to do so, I receive the following error message:

Send Message Error Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired.

To be clear, Thunderbird has no problem finding and using the certificate right after I set it—the problem only appears when I restart Thunderbird and the appearance of the certificate in the settings changes. The certificate does not expire until April 2025, so this is not the issue. The issue also occurs with another account using a different certificate that is also unexpired.

I am using Thunderbird 115.12.2 (64-bit ESR) on MacOS with Apple Silicon.

Hello,

My friend recently encountered an issue where he can no longer send email messages. Suddenly, all the buttons in the "Message" tab, except for "Create," became disabled. Additionally, the "Send" related buttons in the message creation window have disappeared.

I attempted to restore these buttons using Alt -> Toolbox, as suggested by similar questions. While the buttons do reappear in the toolbox view, they vanish again once I exit that view. All outgoing servers are configured correctly, and this setup has worked for several years without any problems. It seems that something is now blocking the ability to send emails.

We also tried updating and reinstalling the Thunderbird client, but nothing has resolved the issue.

Attached, you will find images of the disabled menus and proof of the correctly configured outgoing servers. Apologies for the software being in Russian; I hope it's still clear which buttons are disabled since the interface layout is the same.

Any suggestions would be highly appreciated! Thank you.

Hello,

I have been using Thunderbird for many years without any issues. I recently bought a laptop running Windows 11. On this machine, I have two accounts that cannot send emails via SMTP. What is puzzling is that I can retrieve emails through IMAP without any problems.

For another account I had to use STARTTLS to get it working. But on my Windows 10 machine, the same account is sending emails correctly with SSL/TLS.

Thunderbird is allowed through the Windows firewall and is on the antivirus whitelist.

I recently fixed an issue (connecting to Gmail) by allowing cookies, so it might be a simple fix like that.

Could someone help me, please?

Many thanks!

Hi!

I realised that Thunderbird keeps deleting my messages in every account from the trash folder. I didn't change any of the settings and I checked them again - as you can see in the screenshot, the settings say to not delete messages in the trash. It's a catastrophe, because I've lost messages that I had to check again.

-> Is there any way to restore messages that Thunderbird deleted without my permission? -> Is there any way to make sure that Thunderbird does not delete messages any more?

Thank you!

Version: 115.3.1 on a Mac

Hello --

Not sure when this happened.

Got 2 email accounts, account X and account Y. All was working fine until today, 6/27/24. Both have different outgoing SMTP servers.

Now I am trying to send, it is asking for passwords, which I have and is 100% correct. In fact, if I put in wrong password it tells me, so I know it is communicating. When I put in the correct password, I get a timeout on BOTH SMTP servers.

I disabled Norton Firewall.

Works fine from another PC app (poppeeper) and from my android (k9 mail). Both accounts are IMAP.

Neither SSL/TLS or STARTTLS makes a difference. Nor did a re-boot.

TB 115.12.2 (64 Bit) on Windows 10

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mailroom4.hostrocket.com timed out. Try again.

Description: hostrocket Server Name: mailroom4.hostrocket.com Port: 465 User Name: ernie@e(redacted).com Authentication method: Normal password Connection Security: SSL/TLS

Anything change?

When opening a website, the url has a padlock with a red line thru it (unsecured), the browser then waits about 5-8 seconds for the red line to disappear (secure )then begins loading the content. It behaves on win 10 and android devices. Upon refreshing Firefox on win 10, it got faster, but reverted. Unchecked wait for secure sites doesn't help.

After auto update this error message came up and will not allow Firefox to open. Earlier in the day it had also updated ( not sure to what version) and was working fine. Laptop was then shut down and turned off for aprox. 1 hr. I then turned it back on and tried to open Firefox and it again asked to allow Firefox to make changes to my computer to which I clicked Yes. It then would not open and this error came up. error message Platform version 127.0.2 is not compatible with minVersion >=127.0.1 maxVersion <= 127.0.1

Hi,

Progressive web apps do not have the option to install, just "Add to home screen".

For example, https://whatpwacando.today/

Related, it does not support the browser event beforeinstallprompt.

Thanks, Paul

Since downloading latest update, requested by the software, it takes 2 or 3 times longer to go to most websites, but it takes 10 times longer to go to a Youtube video. (Generally 10 to 30 seconds).

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

About once per week, I'll be using Firefox and it will stop working. I'll close it and open it again and it gives me an error message "The application "Firefox" can't be opened."

If I download Firefox and reinstall it, everything will work fine for another week and then it will do it again. I'm not doing the same thing when it breaks. It does it on both my Mac Mini (macOS 14.5) and my Mac laptop (macOS 12.7.5).

It just started happening in May on both. Nothing has changed on both that I can think of.

Since my last upgrade my You Tube starts up in the tiny right hand screen, fails to go to full screen or just disappear unless I close Firefox and restart often multiple times. This only happens on Firefox and only since the last upgrade.
