Thunderbird Support Forum

Numerous users of Thunderbird have expressed their total dissatisfaction with the recent upgrade, especially the new font and layout in the email lists. Why has the Mozilla team ignored requests to return to the previous load to restore the font and list displays? Do you expect users to support your product when they totally do not like the new version?

How do I configure contact in address book to receive TEXT message instead of HTML. Prior to 115, I could do it. The reference on the internet references items that are not part of the current implementation. The reference is 7 years old.

From time to time I loose my ability to send emails. I check the settings and they are as they should be and have been for the many many years I have been using Thunderbird. I just don't know what to do to fix this problem.

Hi, I have been a grateful and happy user of TB for over a decade.

Then TB updated to 115.

Currently at Version 115.4.1 OS Linux 4.18.0-477.27.1.el8_8.x86_64

I posted about it taking a long time to start up when using Unified folders, and this was fixed by me doing a clean install of 115 which took me a half day. However it still takes much longer to start up than previous versions to 115.

I still have the issues that I posted about: - Inbox displays incorrect number of messages - Issues with forwarded messages that also happen when using Unified folders. So I dont use Unified folders.

I now also have the issues (that I have not posted about): - Sometimes TB shows an empty message with a date of year 1969 - Sometimes when I compose a new message, which opens a new window, and then I switch out of that window back to the window that has Thunderbird in it, the new message window just disappears, along with the contents I have typed into it. Poof.

With TB pre-115, I always felt it was stable and reliable and had few issues over the years.

With 115 I now feel there are many issues, that I dont have time to dig into, or post about.

If I am using Firefox and I click "Email a link of this page" in TB, first the main TB application opens, and then a new separate window opens with a new message that contains the info of this page. In previous versions, the main TB application did not first open, just a TB new message window would open. This was much faster than what 115 does.

I have a number of email accounts in TB and I cannot use Unified folders, so I have to check the Inbox and other folders of each account separately.

I would install the Unified Folders Debugging 115.3 addon but I noticed it gives a warning before install that says it will have access to my whole computer, and my company's security policy will not allow installing based on this warning.

To be clear, I am not posting this to request help, nor to complain about this. I am posting this because I am a grateful long term user that appreciates what Mozilla provides, but think it is important for Mozilla to know the amount of issues that some users are experiencing with 115.

I use a Linux distro that lags having the latest version of TB, but I have checked the release notes of 115.4.2 and 115.4.3 and I dont see any of these issues being fixed, but I look forward to them hopefully being fixed in upcoming releases.

Last week email layout and format appeared to change or update on my laptop. Since then I continue to get "There are no new messages." Note I can send messages out, and I can both send and receive messages on my phone. Wondering if the different taskbar including Get Messages is working right. Checked all settings, etc. Hope you can help.

bold text I can't find how to write an email in Thunderbird. The new interface is WORSE that previous and IT HAS ALWAYS BEEN BAD.

It is a very bad sign that I have to find my password and log into Firefox to tell you that the email service on Thunderbird SUCKS.

Maybe if I GOOGLE looking for an answer someone will post directions how to use your product.

about middle last week started receiving error message: An error occurred while sending email. The mail server responded <handejel@triad.rr.com> sender rejected. The email address you are sending as must match the mail address you used to auth. Please check your SMTP settings AUP#Out-1500 Please verify that your email address is correct in your accoun t settings and try again.

I have been on the phone several times with internet provider and verified that all settings are correct, Attaching images of settings

Please help a 76 year old granny with no kids or grands to help!!! Thanks in advance.

-Every time I start Thunderbird, I see my emails from 2009 at the top instead of auto-scrolling down to the newest. -When opening a MAPI email with a recipient email, the last letter of the email address is cut off in its fancy drawn box. -The form displaying conversations should automatically expand the tree, or at least have an option for that, and auto-expand the tree on a single result. Also, the ">" sign is not prominent enough to indicate that there are more emails in the result resulting the most confusions on workplaces. It's just simply a bad design.

thank you

Hi, I'm trying to add a new Outlook e-mail address to Thunderbird but I keep getting the following message: "Configuration could not be verified, If your username and password are correct, it's likely that the server administrator has disabled the selected configuration for your account. Try selecting another protocol." I have tried both POP3 and IMAP but I get the same message. Any help would be appreciated.

I receive emails from four different accounts in Thunderbird (two from Comcast, and two from Outlook). Most of them are working fine, but one of the Outlook accounts has not been working correctly for the last few days, apparently since the last update, 115.4.3. Emails to this one account have been delayed by several hours, sometimes by as much as twelve. I have not changed any settings at all. The emails are not in the account online, so they seem to be floating around in cyberspace somewhere before they finally come through in Thunderbird. How can I fix this?

The message info portion of inbox messages has increased in size the last couple of weeks which makes the portion for reading the message quite small. How do I decrease the size of the message info portion?

In the German article "News in Thunderbird Version 102" is stated that I can get a colored picture when selecting "Rich Text". I find no possibility of selecting "rich text". Where is it?

I am on Version 115.4.1

Thanks in advance!

In the new Thunderbird (why was the phantastic "old"-one being changed ?????) there is a "Import and Export Canter". I can't find it. where is it?

I am on Thunderbird 115.4.1

How can I store an adress book on an USB stick to move it to another PC? When selcting Help - Tools - Export I get a page which exports my 6 GB profile folder. What does this folder contain? What is the difference between a Thunderbird profile and the Thundebird profile folder?

I am on Thunderbird 115.4.1

My son's email address has been in my Address Book for years with no problems. Recently his emails have been going to Trash. His are the only ones going to Trash. How do I correct the problem?

The Windows 10/11 App Store version of Thunderbrid is very slow with new versions. My Thunderbird is on version 115.4.1 and that is the latest version from the App Store.

I hope it will be updated more quickly in the future.

Thank you
