I copied my Thunderbird profile from an old Win 10 computer whose motherboard was failing, and I managed to get the profile copied before I completely lost access. Now I no longer have access to it. I did not use Mozilla Backup. I downloaded Thunderbird on a new Win 11 computer. On the new computer, I set up Thunderbird. Then I deleted the new profile and pasted the old profile. Now Thunderbird will not open at all. It says, "Your Thunderbird profile can not be loaded. It may be missing or inaccessible." I have uninstalled and reinstalled Thunderbird, but I still get that message. How can I fix this? Thanks, Teresa

I've had thunderbird for years, for the task component. It's wonderful. I got a new computer, but now have lost all my recurring tasks. I saved the profile on our network but cannot locate where to put in the path so import the task file into thunderbird. I did not find it in the community forums; so I must not be asking the question right. Any assistance is helpful.

Thank you

I'm on Thunderbird (128.6.0esr (64-bit)) on Fedora/GNOME. I've noticed, that whenever I launch Thunderbird, it takes several minutes (!) where it says "Connecting to mail.myserver.com" in status. I'm using my own postfix/dovecot server with imap and I don't have this problem on Thunderbird Windows for instance, where it connects right away on startup. After the initial slow connection, it works just fine, when I manually trigger to scan for new messages (instantly). I tried literally any option within Thunderbird to fix that, without any success. It seems to be some trouble with resolving / dns or probably ip6/ip4, but then again, why would it work normally after the long connection time in the beginning? Any clue what might be the problem here?

Hi

Long-term Thunderbird user and in the past couple of months Thunderbird on my PC on connecting to my mail server goes to a time out (about a minute?) before then downloading new messages. Connecting from my laptop is instant.

The PC - which is relatively new - performs well otherwise.

Checked settings on both and they are identical, save for the laptop.being 64-bit and the PC 32-bit versions.

Any ideas for me to try?

Many thanks

Netflix says I need the the latest version of firefox. At the top of the screen it says "Firefox is installing components needed to play the audio or video on this page. Please try again later"

As far as I can tell nothing is installing and I need to actually do something to resolve this issue. Unfortunately I don't know what. Please help me resolve this issue.

I'm running Thunderbird on Mac OS 15.3. I have two POP accounts in Thunderbird; the configuration has been stable for years. This evening, I went to add a new account, and Thunderbird seemed to have decided to update itself, including flipping me over to Chrome where it opened a page about Supernova.

Thunderbird relaunched and came up with an empty "Chat" window. My usual mail window is gone -- and I can't get it back. I can't get an "About Thunderbird" window to open.

I actually can't figure out what happened. My mail appears to be gone. My accounts seem to be gone. I can't open Settings, I can't open Account Settings.

Wait, the mail accounts seem to still exist -- I can tell Thunderbird to check mail, and the POP server shows the checks happening -- but if I send mail to myself, nothing opens. Also, all of the Layout menu options are greyed out.

Help? :-)

Thanks, Vince

Hello! And THANK YOU!! As you can gather from the subject line, I want to know if Thunderbird can be loaded automatically upon booting my computer?

My OS is Linux Mint 22.1 Cinnamon, Cinnamon Ver. 6.4.6 Thunderbird-Nebula 128.7, 64Bit for Linux Mint-001 - 1.0

I also have a master password enabled on my TB installation.

If not, maybe it could be added to a future release:)

Thanks again, MA

Hello,

I just moved Thunderbird from Windows 10 to Linux Mint 22.1. All of the folders are now showing the emails without the date, subject, from, etc. Instead, attached is a screenshot of how one email in my inbox shows it. The layout is set up for “Classsic View”. I’ve tried all of the views, and it makes no difference. I've been through all of the menus and the account settings and can’t find anything related to this. And even though there is a “sort by date, descending” option set, the emails are in ascending order. No columns appear at the top of the folder view. I can’t figure this one out, and a search of the internet doesn’t show anyone else having this issue. Any ideas?

Thank you.

On January 21st 2025 I changed my Spectrum account password. Almost immediately Thunderbird could not log into the spectrum maintained "mail.twc.com" server. When I called Spectrum support I was told the old Spectrum use of separate passwords for SMTP and IMAP was changed to use the same password as the spectrum web page which is now the same for all spectrum logins, a "one password to rule them all" scheme in November 2024. I changed the passwords in Thunderbird for IMAP and SMTP, but it still will not connect. If I do an auto populate attempt, the server actually responds with the correct setting so I know I am reaching the server. After five days trying to resolve the issue with Spectrum I was told this is a know issue with Thunderbird and it is not the server but the third party application. It is bad enough they reconfigure things like this without disclosing it. It baffles me that the changes they claim were made in November 2024 only make themselves known when the service stops working nearly three months after the change and only when I changed the web site password. Anyone know how to solve this? Thank you so much in advance.

Hi,

I'm currently on Firefox Developer Edition version 136.0b6, and for some reason the search bar no longer displays the https:// header. Is it possible to turn this back on?

I have forgotten the purpose of the green outline around the page's border. What does it do and how to turn on, after turning it off. Thanks in advance. Let me know if this is an extension or some other feature. Thanks, JJE

I need help on getting.back to the spot I was at .it like I get ready to go back to were I was at.and sometimes there is so many buttons.and things til it will overwhelm you.so there needs to be one button to push and get u back to that spot.like on u tube there isn't a spot to wher8e u can it in your play list unless you mess with it so by then you can't get back to the song..are u end up looking for another song are having to re program the song on utube.because it's easy to lose the song by accidentally touching the wrong button.

For a few months now I get a Send Message Error whenever I try to send an email from one of my addresses (see first screenshot below). I've checked my SMTP server settings and they all seem to be correct. (2nd and 3rd screenshots). I'm using the latest version of Thunderbird on Mac OS 15.3 Sequoia. I have no firewalls. What could be the problem and how can I fix it?
