Email from a trusted address over past decade is suddenly going to Junk as of today. Cannot see how to whitelist the Sender, and googling the question tells me to go to Tools>Options, however Options does not show in the Tools menu.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

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.

I composed an outgoing email message that I wanted to keep for future use, and saved it as a Template. That not only saved it under the unified Templates heading, but created a second appearance of my main email account with its own Templates subfolder. At that point I decided I really didn't want to keep it after all, so I deleted the message, but the second Templates folder didn't disappear; its still on the tree list as an empty folder. Right-clicking that folder doesn't have a Delete function, but it does present a Repair option, but running that doesn't help. How do I get rid of that unneeded individual email account listing and the empty Templates folder?

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

Hi,

I have a Mac with Sonoma. Somehow a while ago I ended up with Firefox ESR, which I was told that will not be supported after September.

I am a non-technical user. While I do have Safari and Chrome, I would prefer to continue using Firefox.

Could you please let me know the steps to execute to somehow switch from the ESR version to the current normal version without loosing settings, bookmarks or ending up with problems? Thanks in advance.

I am searching for a solution for my problem and maybe this is a possible new feature that would help many users. When I open my thunderbird, all attachements open in a new tab, easy and very usefull because of the invoices i need to pay are always open, and when paid i save+ close them. But then i have to send the invoice attachement to my accountant. So i have to go to the original mail AGAIN forward this mail to the accountant etc.....It would be easy if there was a little button in the open attachement tab that directly opens a new sendmail tab with the open attachement already included in the concept.....Maybe i didn't searched very well....BTW I love thunderbird and install it @ all my customers sites instead of MSOutlook, plugins are fine an email reading is once set up correctly the most easy to read interface. the attachement tab is displaying an url like : imap://my%40mail%2Ecom@imap.mailserver.com:993/fetch%3EUID%3E.INBOX.xxxx%3E128?part=1.2&filename=20210446.pdf&type=application/pdf. I can not even get that by a right click+ sent to email to work.....Yup I'm Belgium and dutch......so i hope i made my idea clear by not using the translate apps and just my brain......:)

Hi, really thank you for your great work.

1. My question

I observe that in other editors like VSCode, Sublime Text

If nothing is selected, and I press Ctrl+C, and Ctrl+X the current line would be copied/cut

meaning while in Thunderbird nothing is copied/cut.

※I write only text mail

1. My suggestion

Is it possible to implement this feature? Would be very convenient.

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

After Firefox updated my browser version to 129.0, my username and password no longer work on my credit card website. I contacted tech support at the credit card banking site through a live phone call. I told them about the upgrade and also that I can use Firefox on my iPhone to login successfully. I don't know what version is currently on my iPhone but it does work there. This problem is specifically on my Mac Mini. I also can login using same password and username on the Mac through Safari. Their tech support said the problem is with that version (129.0) Firefox web browser. What say you? Thanks.

When I receive an email that has a link, Firefox opens without any of my settings. This also happens with Firefox pop-ups, which indicate I don't have certain products, such as Web Advisor, even though I do.

I guess the first question is why a new iteration of Firefox is opened when I already have it running.

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods."
