I have two Mac systems, an M1 MacBook Pro and a 2018 Mac Mini, both systems are running Sonoma 14.6.1. Last week I had to reinstall MacOS Sonoma on my Mac Mini (2018). After installing Thunderbird I noticed a difference between the two systems. I’ve always had the single line email listing as in the screenshot MBP, but now the Mini has a two line email listing as in the screenshot Mac Mini. How do I get back to the single line listing?

Ever since I upgraded to 115.10.1 (from a much earlier version, which worked well), Thunderbird is randomly very slow.

First off, at opening time, it takes ages (over a minute) to download some incoming (small) messages - while this was definitely not the case with the previous version I was running. Sometimes, it hangs (for anywhere from 15 to 60 seconds) while I am typing a message.

Also, e.g. today, I tried to send an email (250 KB or so): it just kept on saying "sending". When I clicked (after a few minutes) to stop the sending, the window closed without further ado and I couldn't find the message anywhere (not in the Drafts, not in the Sent). I did it again, it then hung on copying the message to the "sent" folder. When it finally said it failed, and asked if I wanted to have it copied to a local folder, I clicked "yes". Upon checking, it had stored it in the "sent" messages, not locally...

I am running Windows 10 Pro, with ample memory and disk space, and a fiber optics connection. The CPU is not overloaded at all nor any other ressource.

It is becoming increasingly annoying.

I'm running Thunderbird 128.2.0esr (64-bit) on a Windows 11 PC. I can't find any way to associate a *.log file with notepad, even though this is the my windows default.

• Other file types work fine
• But Notepad isn't in the list when I double-click the file and I have to browse for it every time.
• When setting the default for another file type, it said this could be changed in "Options". I have Settings, but not Options. Under Menu > Settings > General, it has "Files & Attachments". Under this there are 2 columns: Content Type and Action. The only thing listed is Portable Document Content (PDF) and no way to add anything.* Bulleted list item

Hi. I have created 2 subfolders in "Drafts", which ALSO turned into draft folders:

• The folder icons switched from the standard folder icon to the "Drafts" icon.
• The right-click context menu is reduced (just like for other special folders), e.g. the "delete" command is missing.

So how can I delete this misbehaving folder now ?

I doublechecked in my account manager and via config editor that the subfolder are NOT used as DRAFTS folder for any of my (POP3) accounts.

Thank you so much.

Is there an option to set multiple event reminders for a single event in the calendar? If i set up or edit an event using my phone app I can choose to have multiple remiders for the same event (e.g. set a remider to 30 mins before the event and 24 hours before), and Thunderbird remembers and reminds me of both (altough only showing one of them when looking at the event in the calendar). However i haven't found any option within Thunderbird to set multiple event reminders, I also looked for extensions for this functionality but haven't found any that appear to address this.

I am running version 128.1.1esr (64-bit) on Windows 11.

A few weeks ago one of my email accounts stopped working so after attempts to find and fix the problem I resorted to deleting and recreating the account in Thunderbird.

The account is a hotmail.co.uk account and the server type is "POP Mail Server".

I noticed that there were fewer folders under the account (Inbox, Drafts, Sent and Trash). There may also have been a Junk folder. I thought that perhaps Thunderbird would create any additional folders as and when messages appeared in them, but I have now discovered that I have messages in the Spam folder on the server but they do not appear in Thunderbird.

Please can someone tell me what I have done wrong and how can I fix it.

Many thanks.

Today I changed the password on one of my gmail accounts. I edited the password in Settings in 3 places: imap, smpt and oauth. Next time I started Thunderbird I got a gmail authentication pop-up. Se first screenshot. The email address was shown correctly. When I clicked Next, I got the failure message. See second screenshot. I rebooted and tried many times with same result.

I have several other gmail accounts on this same Thunderbird client and they continue to work correctly. I know my password is correct because I can access this email account both directly on gmail and also on another computer where I set up Thunderbird just to test for this problem.

Any idea what is going on and how to fix it?

I was using Thunderbird for Windows 10 normally for many months. Recently, whenever I launch the app it immediately freezes, and I have to force quit the application. Reinstalling the app does not fix the issue. I haven't tried deleting my profiles yet, but I would like to avoid that if possible.

Since acquiring Version 128.2Oesr (why I am on the esr channel I do not know !) my Hotmail accounts have difficulty in receiving e-mails .I have changed the SMTP outgoing server to "outlook.office365.com" and OAuth2 authorisation but I cannot find the server setting for the incoming SMTP server to change that address & initiate OAuth2 - hence it remains imap.outlook.com with "normal password" and form 16th September I will not be able to receive Hotmail e-mails

My thanks for any responses ..I have used Thunderbird for over 20 years & this is the firt time I have real difficulty. Had I been left still with version 115 no doubt I could have solved the problem so I would like to be removed form the "esr" channel .

Greetngs to all,

                         I'm using Thunderbird Version 128.2.0esr with Windows 11.

I have clicked on View/Folder/Unified Folders but none og my IMAP accounts are listed.

Can anyone please advuise how to resolve this issue?

Thanks,

             Scott

Using Thunderbird 128.0.1esr (64-bit)

I have just bought a new Windows 11 laptop to replace older model. Using the old laptop, email messages are displayed in a single line format, which you click to open the message.

Using the new laptop, messages are displayed in two lines, taking up more space.

I much prefer the less cluttered format, and wondered whether anyone could advise the settings I need to alter.

Grateful for any advice.

Since the latest update 128.2.0 I am getting message "The certificate for pop3.go-plus.net is not valid for that server. Someone could be trying to impersonate the server and you should not continue." when I try to receive emails. Everything worked fine up until today, even though I had to click an "Certificate Exemption" box after re-starting. How can I get to receive emails? They appear to send ok.

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

Thunderbird v.128.1.1esr (64-bit) (up to date) Windows 11 Pro v.23H2 OS Build 22631.4037 No VPN

Two days ago my Thunderbird installation stopped being able to access my Gmail account. Everything was working fine up until then. Now I get a notice to allow Thunderbird to access Gmail, I click 'Allow' and it fails to authenticate. Collecting mail from my other non-Gmail accounts is unaffected and works fine.

I see these permission approvals are triggering email alerts to my backup Gmail account for this one re: "A new sign-in on Windows" and I am consistently clicking "Yes it was me'" with no effect. I have not done anything to block this activity, and I have no problem logging into this Gmail account from any web browser using the same credentials I am using with Thunderbird ... and which were already in place when this started happening 2 days ago.

I checked in Thunderbird Settings > Privacy & Security and cookies are being accepted, and I can see the cookies in the list.

I have tried deleting the saved (unchanged) password, removing the cookies, and even removing the account and setting it up again, with no joy.

When re-setting up the account this morning, the account creation does not complete and I am receiving this notice: "Unable to log in at server. Probably wrong configuration, username or password." (see attached screenshot)

The username and password were (a) unchanged from 3 days ago when this worked fine and (2) confirmed as I can log in to that Gmail account just fine with any web browser using the same credentials, even with incognito browser.

Thinking maybe the Thunderbird auto-detected configuration is incorrect, I changed the IMAP Connection Secutiry setting for the account from SSL/TLS to STARTTLS where it took about 2 minutes on the Checking Password stage and ultimately failed with the same error message.

TIA for any assistance with being able to use Thunderbird once again to work with this Gmail account.

Since yesterday, I suddenly cannot receive mail from the office365 server with thunderbird. Authentication passes, but timeout occurs when receiving mail. There is no problem with sending mails. I did not change anything in thunderbird settings yesterday.

[setting] Server Type: POP Server name: outlook.office365.com Port: 995 Connection Protection: SSL/TLS Authentication method: OAuth2

Version 115.8.1 (64) I block messages by domain (domain.com), rather than whole addresses, because spammers are constantly changing their whole address (nutjob@domain.com). The filters don't always catch them when they arrive, and then they sit in the folder, indefinitely. The "Manually Run" and "Periodically, every 10 minutes" options are both selected. The "Periodically..." option does not appear to be working (as I expect it to), so I eventually will go and hit the "Run Now" button to get rid of unwanted mail. I can also quickly delete them using the "Run Filters On Folder" option in the "Tools" menu. It would be great if the filtering worked automatically. Thanks

Hi, after an update, i have the newest version of Thunderbird installed. Upon starting, it says: "Unable to use profile when you launch an older version of Thunderbird." I cannot start the program. But it is the newest version... What can I do? Thanks Lukas

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.

Dear All,

I think that is a compability problem of Citadel with Thunderbird email client.

After several steps to try to solve the problem I found that Citadel is not compatible with the last version of Thunderbird.

I tried Linux (Centos 9) and Windows Thunderbird. I tried my affiliation network and with my mobile hotspot.

I can send emails with my Android email client.

I am thinking to make a downgrade of Thunderbird. I have there all my emails from always.

But first I have to backup everything of Thunderbird. Time consuming task.

Some help is needed.

I have noticed an issue with lists (bullet & numbered) for a while now and thought it was about time I checked to see if it can be sorted!

If I start a new message and there is no text and then I press the Bullet button then this is OK.

However, if I.....

• Start with a blank message
• Type a line of text
• Hit Return twice
• Press the Bullet button - this moves the cursor up to previous line
• Press the Bullet Button - this moves the cursor up to the end of text on previous line
• Press the Bullet button - this put a bullet symbol at start of the line of text

This makes it very frustrating trying to add a bulleted list in the middle of a message.

I saw a previous thread when the OP was having the same problem and his solution seemed to be connected with his HTML signature, but I don't have a signature set up.

This is version 115.9.0 (32-bit) running on Windows 10.

Any suggestions would be gratefully received!
