Thunderbird is completely unusable in the latest release. Attempting to set up a gmail based account results in

"Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to 192.168.1.250. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

That's it. No options, no explanation, no KB articles, nothing. It just doesn't work. But why is Thunderbird trying to open a web connection to my local machine? If it's trying to talk to itself, why can't it? This is clearly an issue with trying to authenticate to Google as it happens after auth, but come on, this is a given requirement these days. If your app doesn't work out of the box (MacOS 13 btw), it may as well not exist for the OS, so this is very confusing.

Trying out older versions was a real comedy of failures as well. Too old and it's just a disaster. Too new and it just self updated to 115 again which doesn't work. So kinda seems like this is not a functional app anymore, at least not on Mac. Baffling. I guess it can only be used with legacy style email systems.

Hi. It looks like there was a Thunderbird update and my inbox and sent boxes are completely empty. It says I'm getting emails (I did a test), but I can't see them anywhere.

In Thunderbird 115, each time I want to reply to a message, the cursor defaults to the "Search For" box under address book contacts. In previous versions, it went to the message pane where I could start the reply message. How do I fix this? Thank you

Sorry, but since you're stubborn and don't support German, you'll have to be satisfied with the Google translator

So, what's with the version 115 of TB? It constantly asks for the passwords of the accounts, although they are all present and working in the profile folder.

If the developer now thinks that I am creating everything again just because the 115 version no longer wants to read the old profile, he has cut it. WE users are the ones who work with it every day and the developer can't just decide what's better, WE users are the ones who have to deal with it, so make sure you get your Schrottige115 version up and running, because NO ONE will want to use it that way.

Sorry if it sounds harsh, but I'm pissed off, Mozilla has been driving TB and FDF more and more against the wall for years. NO improvements just crap.

Sometimes when I delete a group of emails from my inbox it deleted the entire inbox. It has happened twice now. When it did it yesterday I had 8 emails selected for deletion. When I hit delete it deleted all 2200 emails in the box. When it was deleting them I confirmed that only 8 were selected by looking at the number of selected in the lower right corner of the screen. Worse, when I click undo the delete it does not restore the 2200 deleted but only the 8 that I had selected for deletion. This is a serious bug and has resulted in loss of all my emails over the few years.

Hi; I noticed today that many years of archived emails have disappeared in all but 1 account(yahoo). The only years still there are 2020 and 2021 in 5 different accounts. 5 yrs in 1 account and complete 24 yrs in yahoo account. These accounts archives that disappeared are not stored on the mail server but locally. What has happened??? Can I get them back? How do I stop this from happening?

After installing the latest version, when I print an email with more than one pages, the first page is blank after the From/To/Subject info. The rest of the mail continues in the second page. How can i fix that? Thank you in advance

I receive incoming email on Thunderbird, but cannot send mail. I have used Thunderbird for years, never updated it and this problem just started yesterday (7/25/23). I have gotten an error message saying "login to server smtp.nycap.rr.com failed". I have called my ISP, Spectrum, and ascertained that my email account with them is functioning, so the issue is something with Thunderbird.

Hi,

since I switched to the new version of TB, some of my mails are empty in the preview (just a white screen) and also if I open them normally. Same mails are working fine with other mail-clients (iOS) or the standard version of TB.

Any idea to fix that?

BR, Robert

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...

Hello, Since the update to Thunderbird Supernova from version 102 upwards, emails in several email folders are automatically deleted or hidden. The properties in the respective folders are listed under Retention rules: Do not delete messages.

The emails displayed in the folders no longer correspond to the contents in the folders. Example: A folder displays: 7, properties in the same folder displays: 1226 with 447 MB. It looks similar in the other folders.

How can I ensure that all available emails are displayed in Thunderbird again?

A repair with *.msf does not help.

Many thanks for your support. Erwin

As of version Thunderbird v102.13.0 (32 bit) and after upgrading to v102.13.1 I get an error after downloading emails from my gmail account:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I've been using Thunderbird for maybe 20 years now & on this PC since I built it over 3 years ago, this is a new problem that I have not seen before.

Thunderbird is now useless to me. When it connects it starts downloading emails, gets so far & stops with this error. It's now 5:50PM and the most recent email it has is from 07:35 AM this morning. It keeps downloading the same ones over & over again, always stopping at the same one with the same error.

This app is now utterly useless to me.

i have version 115. this is what i expected and its still not possible to adjust : 1. I only need one address book instead of these three:1.all addresses,2.personal ,3.?collected I don't like/wish having this group of 3. Can I install to have just one book? 2.i close tb with opened items. when i open tb these items are still opened. can i install this way: tb opens without these items and goes directly to inbox? 3.I can not drag down from an opened mail - customize toolbars- items that I see in general such as archiving ,unwanted, ? all reply ...Why not? regards

I find it to be a big oversight that the project is so mature but still doesn't have RTL support out of the box. The (unofficial) add-ons that supply this functionality are yet to be updated to be compatible with version 115. Isn't it time to make this part of the base program?
