Everything has been fine for several years but this morning I now get error: TB could not connect to server mail.twc.com, the connection was refused. Spectrum says everything is good on their end. What do I have to do to "fix" Thunderbird? I can't send or receive any emails from 5 accounts with Spectrum and the emails are there when I log in at WebmailSpectrum.net..

The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [SYS/PERM] Your account is not enabled for POP access. Please visit your Gmail settings page and enable your account for POP access.

Hi,

I've just updated my Thunderbird for Windows to 151 and I got this nasty surprise (this is why I hate updates these days).

The message list in dark mode, in a table view, now has this awful pitch black background instead of the normal dark brown as it used to have. It looks OK in cards mode, but I don't like cards mode.

I certainly hope this is a bug and not by design. Can this be fixed, please? It looks terrible, it's hard to look at, like old Windows 10 dark mode or some high contrast accessibility mode.

Thank you!

I was attempting to import the calendar info from my old system to my new one, but the export/import of a .ics file did not work. It complained about information not being found. Then I tried copying the local.sqlite database file from my old system to the new one, that initially did not appear to work either :( Come to find out that the database cal_id fields did not match between my new system and the old one, so even though the local.sqlite file I copied had all of the calendar information, the prefs.js file on my new system was referring to a different cal_id. So I used a text editor to replace all of the cal_id's in the prefs.js file, with the cal_id found in the copied local.sqlite file, and now I have all of my calendar data available on my new system. You might want to make this know to your users, since my original searches on your support site did not present a solution that worked. :(

I just had to reinstall Thunderbird on my computer. Somehow after being away for a year and firing up my computer Thunderbird advised best to reinstall. I was able to get some of my contacts but not all. Thought it would be simple to just export my Thunderbird address files from my Windows laptop and import it to my Thunderbird app on my windows computer. Seems obvious and simple but not so for me. The suggested solutions do not work. Am I missing something?

Using Thunderbird for my mail. ATT Yahoo is my provided. My ATT password is not allowing me to get my mail. I keep getting a message to re enter my password. Password does allow me to sign in to my att account.

I have been using Thunderbird for 20+ years, maybe as many as 30. Forever. I have moved my profile across several versions of Windows and multiple computers. There are files in the root of the profile with a modified date of 2009. There may be older ones in sub-directories. There are 18 folders and 125 files. I suspect a lot of this is clutter left over from earlier versions of Thunderbird. In the Mail folder alone there are several hundred files and folders excluding the WDSEML files and actual emails.

I'm toying with the idea of starting fresh with a clean install of Thunderbird and getting on the correct release channel but I don't want to bring along what appear to be hundreds or thousands of unused files and folders.

I there anyone that can identify what profile files and folders to keep and what can be deleted?

Thanks for your consideration.

The Windows 10 PC crashed after an update, but I have command line access. I copied the profile folder from the Thunderbird installation to a USB drive, but can't find a way to move the subfolders (like 'name' and 'name.msf') to an existing installation on the new PC.

Is there a way to import these into the new installation?

I'm using Thunderbird 152.0a1 (2026-04-22) on Windows 10 64 bit. When I click the "Get Messages" button or File > Get New Messages for > [my e-mail account] nothing happens. The only way I've found to check for messages manually is by closing and re-opening the program.

Today, I have received an email, claiming to be from Mozilla support.

The text is garbled but it appears to contain words, 'hacking', 'paynalti', and 'auto-block'. These are words which immediately put me on security alert. I haven't opened the mail but have viewed it in preview pane. and screen grabbed the attached pdf image.

Any comments?

Thanks, William
