Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Hi, I am using Fibrus email (network name is HomeWifi and network key is Fibrus123). Fibrus uses eero as a modem. I cannot work out the correct server settings in Thunderbird as there doesn't seem to be a place for 'network key'.

Most grateful for any help you can give me.

Since the last update to version 146.00, under the folder Archives, both the sub folders for 2024 and 2025 have changed to Drafts and I cannot change them back to show the year folder (2024 & 2025). None of my other yearly Archived sub-folders are affected from 2016 - 2023.

Under Properties, both show their respective year correctly - i.e. imap://wbriggs1%40sky.com@imap.mail.yahoo.com/Archive/2024 and; imap://wbriggs1%40sky.com@imap.mail.yahoo.com/Archive/2025

I attach screenshots showing the issue and any help would be appreciated.

In essence, after trying various ways of trying to sort the above out, it would be helpfull Mozilla if under the Folder Properties box, I could just change the name back from Drafts to the appropriate year. However, in the folder box when selecting the Name line, it won't allow you to alter the folder name. This would seem the simple solution to any alteration of Folders by being allowed to rename them back to the original name.

I had two emails on my Thunderbird. I deleted one by mistake. The G Mail account still works. I tried to reenter my Spectrum Account and I keep getting that my configuration user name or password are wrong. I checked all settings and they appear to be correct. I also deleted the account and tried reinstalling it and got the same result. I also tried to enter a new email account that I just got. I had the same result. Keeps asking me to reenter the password. (would be helpful if it would say why it is wrong (password, setting, etc.) I spent hours on this today. I worked with the Spectrum agent and we couldn't fix it. Bur it seems to be a general problem because I get the same result with both accounts.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp-mail.outlook.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.

Seem to get this (or similar) error frequently. It's like the things I set randomly revert or change. Have sent images of settings. I certainly don't know what to do.

I want Thunderbird to stop marking everything I delete as having been read. The way it works now, if I accidentally delete mail that I haven't read yet it's much more difficult to find it when everything is marked read even when it wasn't. I searched everywhere and haven't come up with a solution for this. It was reported as a bug years ago and was never fixed.
