Thunderbird Support Forum

after a recent upgrade (91.10.1) Thunderbird no longer has the question about remote content on the email view page. The one with options like show all remote from _ or show only remote content from _. Stilll has the exception section in Settings. Emails show embedded content on webmail. What gives?

I can't control the FONT SIZE of the incoming emails with the new version of T'bird. Hate it!! It's ugly. Looks crowded and, as I said I can't set it so the incoming fonts are a readable size. OR the font size in the individual mail boxes... This lack of control makes it next to useless for me. I'm in my 70s and really do need the larger font sizes.

Hi, I have very frequent Mozilla Thunderbird Crashes on the site. I have noticed that it appears mostly/all the time? when some emails are being deleted, if that makes any sense. This is more of an annoyance, than a critical issue. Just in 2024 the log shows over 100 submitted crash reports. The "good news" is that Thunderbird goes to the "restart and/or quit" option icon for a a fast restart. So any thoughts, suggestions would be appreciated. Thank you . Gerry K.

Hi: I use Thunderbird 38.7.2 on a MacBook Pro with MacOS 10.11.6. Thunderbird tells me that it is up to date, and that I am on the release update channel.

As of today, 9 June 2022, Gmail rejects my password, and re-entering it does not help.

I went into Preferences/Account Settings/<account_name>/Server Settings/Security Settings, Options are

    Normal Password
    Encrypted Password
    Kerberos/GSSAPI
    NTLM
    TLS Certificate.

Nothing about OAuth2.

Read that version 38 of Thunderbird is supposed to be OAuth2 compatible, so I'm stuck. As Thunderbird thinks it is up to the latest and greatest, I cannot update it to something newer. And I do not see a way to enable OAuth2.

The answer is probably obvious. just not to me.

Hello everyone, I just installed Thunderbird Beta (114.0b6 - 64 bit) out of curiosity.

When I import RSS Feed, all icons representing folders are gone unlike on Thunderbird Stable version.

Although Feed Subscription pop up window still show icon for each feed folder.

Is this normal on Thunderbird Beta?

Thunderbird v31.4.0 Linux Mint Debian Edition 3.1.2-amd64 Cinnamon 2.0.14

When clicking on a link within an email, the system crashes and the monitor display displays jagged, diagonal lines. A cold boot is required. This can be repeated.

Same results running in Safe Mode.

Any ideas?

I just upgraded to Mac's latest OS 14.0 (Sonoma.) Thunderbird will not load. When I run the application I get a beachball and an "application) is not responding" message. I have tried rebooting and all the "typical fixes.)

Is there an update coming? Something that I can delete to make Thunderbird work?

Can new folders be created in the 'root directory' or must they reside either within an account or a local folder?

Setting up a mailfence alias using the identity capability. Currently have two folders; me@mailfence.com and local as the initial configuration. Would like to create an equivalent directory structure myalias@ mailfence.com with subdirectories draft, sent, junk, etc. resides outside of both me@mailfence.com and local.

Looking for a native TB approach (if it exists),

I had to delete one of my email accounts (verizon.net) and now want to reinstall. When I attempt to add email account, I get a message "incoming server already exists"! The email account is, in fact, gone. Please help.

With just 2 email addresses that I have been using for years, I suddenly get this Undeliverable message when attempting to send emails using Thunderbird:

"The mail client submitted this message with bare line feeds, which cannot be sent via SMTP protocol DATA command and receiving system does not support BDAT"

I can receive emails from the 2 addresses fine, I just can't send to them through Thunderbird. When I sign in to Hotmail Outlook Live I can send and receive to these addresses with no problem.

I'm stumped! Any ideas? Can I reset Thunderbird?

Thanks

Starting from the app menu button ≡ or the main menu, choose Tools -> Developer Tools -> Error Console.

Copy the text given below and paste it into the Console.

If using version 78 or later, copy and paste the following text: openDialog("chrome://pippki/content/resetpassword.xhtml"

Click the Evaluate button.

If you do not see an 'Evaluate' button, press Return or Enter on your keyboard.

When prompted with the confirmation dialog box, click the Reset button.

The problem is that I don't see an "EVALUATE" button

This after I upgraded to the latest version of Thunderbird.

I've just installed TB 115.6 on my MacBook to see if I like it better than Apple Mail. There is one thing that seems weird to me. Fonts are displayed larger in the Read window than in the Write and Reply windows.

These are my font settings: Default font: Helvetica, size 14 Composition, HTML Style: font: variable width, size: medium

Now if I send an e-mail to myself the font looks larger once I receive the message than what it looked like when I was composing it. And then if I reply to this message the font becomes smaller again in the Reply window.

The font in the Write window has the exact same appearance as in Apple Mail where I also defined Helvetica 14 as the default font. So my suspicion is that the fonts are somehow scaled up in the Read window. But why? And how to change it so that the same font looks the same everywhere?

I've been a faithful Thunderbird user since the beginning - and continue to use Thunderbird with our company's Microsoft365 deployment

until Monday of this week -- when suddenly I find that my credentials are being refused.

The symptoms

• XXX: Connected to outlook.office365.com
• nothing in the activity viewer
• no email coming in

I've read and tried all the fixes proposed in the article at https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 (restarting thunderbird after each step, naturally)

• have authorized Thunderbird to our Microsoft365 tenant
• created and tried registering with a new thunderbird profile
• have set my security settings to 'accept all cookies'
• have used the config editor to remove 'oauth2.issuer' and 'oauth2.scope' values
• I've checked that my account in Microsoft365 has IMAP and Authenticated SMTP enabled

So, since Monday, I've been living in hell, trying to pretend that the Microsoft Outlook app for macOS is useable, but it's practically debilitating to be forced to use that piece of software.

Can somebody please point me to another possible set of steps that I can use to try and diagnose this?

I absolutely hate myself for having to ask for help on this, but I'm at my wit's end...

Since yesterday when Thunderbird updated, I either get an alert sound for new email all of the time (even when Thunderbird is closed and I don't want to be alerted) or none of the time, if I turn the sound off (meaning even when I have Thunderbird open, I get no sound alerting me of new email). How do I set it so that when the program is open, the alert sound works, but when the program is closed, the alert sound does not interrupt my other activities (like work video calls)? Thanks for any help with this.

Thunderbird has changed one of my folders. This now has a different icon (see snip) and I cannot delete it as there is no option. Is it something that I've done and how do I correct it please. Many thanks

The latest version of Thunderbird changed the top menu, and I see a "Get Messages" button, but can't find "Send Unsent Messages" as a function anywhere. I've tried customizing the menu, and I've looked through older help discussions for any ideas, and I've prowled through the settings menus and can't seem to find it. I've also tried right-clicking on things - no joy. I have a message waiting to go out in the Outbox, but no way to send it except Redirect.

Thanks in advance, for any help or ideas!

I have spoken to my ISP and its confirmed, as have I, that I can log on to its website and successfully download my emails so the problem "must" lie with Thunderbird. I am not very technically inclined so would appreciate some advice please, thank you. My ISP technical person (at iiNet Australia) did say they were receiving a lot of phone calls today about email and "blamed" it on changes to Outlook? If this helps. Regards.

I report all spam emails that I receive at my Yahoo email addresses. As it stands, I have to manually check for spam on Yahoo, restore it to the inbox, and then do a separate, manual download to get those messages onto Thunderbird to process and email (my preferred way of doing things). Is there a way/setting that allows Thunderbird to go into the Yahoo spam folder and retrieve those messages as well, in one retrieval operation along with the rest of my mail? Thanks- :)
