Thunderbird Support Forum

I us an M2 Mac. I like Thunderbird, but prefer the Betterbird card view. Is there any way I can replicate this in Thunderbird?

I have attached two screenshots - one Betterbird, the other Thunderbird. I much prefer the Betterbird look, without the card frames and with the blue message header.

You might well say 'use Betterbird then!'. The problem is that Betterbird is not available in a native Apple Silicon version, only Intel, and therefore runs in emulation mode. Thunderbird has a native Apple Silicon version.

Just two small changes. Remove the card frame and make the unread message header blue. Surely that's possible somehow in Thunderbird?

I sent a message a while back about slowness with 115, which I had to download because I had a crash.

There were various suggestions, but no solutions to the excessive slowness with 115. This culminated to day in a long 'no reply' mail which suggested the issue might be the virus checker.....

I checked again the various messages about 115 - most were archived, only one month since they were posted!!

Is there an issue with 115?? I saw a thread which asked was I having issues with it, my answer is yes, is there nobody out there with a suggestion??

double line spacing forced every time you press enter - Also messages from same sender are sorted and combined into a single line in the INBOX list - how do you keep each message separate? Thanks

The email address that I have used ever since email began has been [edited] @qis.net. Unfortunately, the inbox storage space on Quantum Internet Service (QIS) is only 1GB. I use Thunderbird for emails (recommended by QIS). The account with QIS is an IMAP account.

Yesterday at 4:40pm my inbox became full even though I have moved a bunch of the emails with larger attachments to offline folders within Thunderbird. That's when the nightmare started. No incoming emails can get delivered at this time. Have been in contact with QIS (I personally know everyone there including the owners. They're good people) It seems that we do not have a way to get into the inbox and remove files from their server (s).

After working all night trying to sole this mess, I have set up a new email address to maintain a form of communications on a major engineering project.

The new email address for me should be changed to : [edited] @gmail.com

Please make this change at Firefox. When I try to login on Firefox, it sends a code to the old, non-usable email address. Since the inbox at QIS is full, I can't read it to get the code to respond. If the code can be sent SMS to my cell phone, that would be fine. [removed phone# from public support forum] is the number to use.

I hope all this makes some sense at your end. I am not a guru with this stuff and a very dear friend of mine who was an "IT guru", as I called him, has passed away about 1 year ago.

I appreciate any help you give.

All I get now in my emails are links to the mesages received. This has changed suddenly within the past few weeks. If this can't be staraightened out I will change to another email provider.k

Salve, mi sono creato una rubrica di contatti mail solo su thunderbird. Ho nel frattempo cambiato PC. Come posso copiare o trasferire la rubrica dei contatti dal vecchio PC al nuovo PC? Grazie, Gianfranco.

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

I am using Thunderbird version 115.7.0(64-bit).

The Inbox is 15.5 GB in size as shown in the attached image file,Inbox Size.Jpeg.

The Inbox folder is not displayed as the attached image file,Folders.jpeg, indicates.

Please provide me with a solution to this problem.

I can not get emails anymore. They just suddenly stopped coming in. I can go to my ISP’s website and see my emails but can not get on Thunderbird. I suppose there is a problem with my account configuration but I don’t know what. Any idea what settings to check?

Since yesterday I am unable to receive mail. When I send a test email the message below comes up. Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent...

I have searched, read and tried all fixes on this topic already provided but nothing has worked.

Thanks in advance.

How do I get mail from the 'sent' folder on an old laptop into a new one? I have migrated old received mail and contacts to the new inbox no problem.

Using the export tool is no use - the Zip folder it creates titled 'Thunderbird_profile_backup' is corrupted and nothing can open it. I manually copied all files into an external drive and opened them in the new Thunderbird. That imported contacts but not mail from the old 'sent' folder. How do I get all those old sent mails out of the old device?

Basically, when I have a threaded message, I don't see the > to drop down information to show the threads from the subject pane in the subject field.

I have gone to view, sort by threaded. I'm led to believe I should see something like this:

Subject : Top Level of Thread

 |
 ---> Subject : Re: Top Level of Thread
      |
      ---> Subect : Re: Top Level of Thread

But I see none of that. It's just one flat subject. It doesn't even tell me someone has replied to me. I have to go into the mail to see that. I have added the conversations add on just to get a glance of that, because I'm seeing nothing.

Image attached of what I see.

I have been using Thunderbird for probably greater than 15 years (back when I was in college). The last couple of years I have noticed an issue of when deleting multiple emails that has gotten progressively worse, where the entire application will hang in "Not Responding". For a test, I just deleted a batch of emails from the last month (newsletters, notifications, etc), it was 113 messages, and froze the application for more than six minutes. This was on my hotmail account but the same happens for my other accounts as well (all configured as IMAP). The issue has persisted through uninstall/reinstalls and even across a replacement computer. No extensions are installed.

Any thoughts?

I always use Mozilla Thunderbird for email. Today, it would not send outgoing email. Any email gives me a failed message: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 665754780026FB52). Please check the message and try again."

My ISP insists the problem is not with their server, and I need to have Mozilla correct it.
