Not sure how it happened but I've suddenly lost access to my Google calendar. On the bar on the left side of my calendar display screen there is a list of two calendars, Home and my email address, which I think is a Google calendar. Even though I check "Show all calendars" it does not show my email address calendar. And if I click on only to show my email address calendar it shows nothing at all. On my Pixel cell phone I can still see both the Home calendar and the Google calendar, so I guessing Thunderbird has just lost the link, although it shows a googleapi address when I click on properties. When I accept a Zoom calendar listing it has always and still shows up on the Home calendar. This seems most mysterious. Anyone have an idea of what I should do? Is there anyway I can rebuild the link to the Google calendar?

Since the latest update a Yahoo Mail sign-in keeps popping up...sometimes two different versions. It's driving me nuts. Should I uninstall/reinstall Thunderbird. It's so frequent for no apparent reason that I may have to give up Thunderbird and many, many years of use...and donations. thx, deanna

At one time before several updates ago, all messages in my inbox were separate. After a previous update, reply or messages with the same header started be be nested, each one showing only the sender and the subject, which is now the same. I am forced to read through them all to find the one I want. Deleting any in the change can be hazardous.

How to go back the old way of message display?

When I send an email from my account dezandcathy@optusnet.com.au, I receive a message "Your message was sent but a copy was not placed in your sent folder (sent mail) due to network or file access errors. You can retry or save the message locally to local folders/sent mail-dezandcathy@optusnet.com.au" This problem has only occurred within the past week. For some of my sent emails, I have retried sending the message and it has appeared in my sent email folder, but not for all the emails I have retried. Checking with the recipients, they confirm receipt of my emails even though they are not shown in my sent email file. Can you suggest a solution? Thank you Derek Maule

Preamble:

1. There are 34 email Accounts listed in left column.
2. (Image 1) When in "Mail" column I can see down to only the Account Name (address). There is only the Account Name and Inbox.. nothing else below that can be seen - no Drafts, Sent, Archives, Spam, or Deleted. Anything below is missing too.
3. When choosing "Account Setting", everything for last account shows up, plus Outgoing, Add-ons (Image 2). Too, we can see the Offline/Online Icon.

QUESTION: How may I fix it so that the last account shows all sub-sections of the account - i.e., Server Settings, Copies & Folders etcetera right on down to Online/Offline or at best, down to "Return Receipts" for the last account?

Thanks for volunteering, ~r

When setup the SMTP server, under the security and Authenication; only "User Name" is provided, but there is no "Password" field provided for input, please resolve this problem.

Since to old add-on enabling customization of the message header toolbar doesn't work now, where might get one the is compatible with Thunderbird?

Thanks, James

Hi. From 27 feb I can't login to yahoo mail through mozilla thunderbird.

When I start thunderbird, new windows is opened with this link

https://login.yahoo.com/account/challenge/fail?src=oauth&client_id=dj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz&redirect_uri=https%3A%2F%2F127.0.0.1&done=https%3A%2F%2Fapi.login.yahoo.com%2Foauth2%2Fauthorize%3F.scrumb%3D0%26client_id%3Ddj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz%26code_challenge%3Dt6iqw87GVPZ649cCvOEh2L1hwkUluBhsrwxCdVTXAOY%26code_challenge_method%3DS256%26redirect_uri%3Dhttps%253A%252F%252F127.0.0.1%26response_type%3Dcode%26scope%3Dmail-w%2520ycal-w%2520sdct-w&acrumb=0EYriz7Z&display=login&authMechanism=primary&e=true&pcn=password&eid=3692

When I tried to login I see this information:

An error occurred.

We couldn't log you in. Please try again from a different device.

This is very strange, because I tried it on another PC and this is the same. It looks that yahoo even didn't try to check password, because this is not matter if I wrote correct password or different - I see the same information.

Please help. I have two yahoo mail account and this is the same.

Both accounts works well on another e-mail client and I can access to my account without any problem by browser. This is only thunderbird problem.

Just started using Thunderbird, coming from MS Outlook. I have exported my contact details in Outlook to a .csv file, and tried to use this as the import source to transfer the details to Thunderbird address book. I have checked the fields to transfer, but none end up being passed over. The .csv file appears to hold the correct data with the correct field headers. Although I do not have many contacts, transferring them individually by hand seems a very old-fashioned thing to have to do lol

I don't know what to do when February 29 is in my calendar, 2026 is not a leap year. I've found nothing to help me. I have the latest version if Thunderbird. Thanks

During recent update 148.0 (64-bit) google calendars are not shown either in "Events and Tasks/Calendar" or in "Today's Pane".

Subscribed calendars are still there, but nothing is shown in the days/weeks/months entries apart from the first calendar in the subscription list! Nothing else. And nothing in today's pane.

Reinstalled Thunderbird and reinstalled "Provider for google calendar" but nothing changed.

Thanks, GG

Issue

Thunderbird fails to wrap long lines of HTML-formatted text that is wrapped in a <pre> tag. This behavior is consistent in both the email viewer when viewing received emails, as well as in the email composer when writing an email containing preformatted text.

What I tried

1. Make all settings of config editor that contain the word wrap as true 2. make a userContent.css stylesheet within the chrome directory within the profile directory.

Question

How do I post the offending HTML code (and the CSS file I tried) on this forum?

How do I force Thunderbird to wrap preformatted text?
