Hi All, I have been sending emails through Android Thunderbird, but they aren't being synced to the server, so I can't see them anywhere else. I've set the Sent folder to sync (as well as the Inbox). Pressing the sync button just spins the indicator, but doesn't actually sync. When I try to move or copy messages, an error comes up saying that messages can't be copied or moved that aren't synconised. How can all my messages (sent, inbox, everything) be synced so that I can see them everywhere? I've just turned on sync debugging, will see the results soon.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.

I occasionally have problems with Thunderbird insisting that posts in my frequently visited newsgroup are expired when they are not. Previouly, I've been able to resolve this problem by simply unsubscribing from the newsgroup and then subscribing again. But today, when I tried that technique, Thunderbird told me that there were no messages at all in my newsgroup. This is flat-out wrong because the newsgroup is quite active. Right-clicking and choosing Get Messages did NOT change the situation.

Then, to add an extra layer of aggravation, I added a second newsgroup to my subscriptions, one for Thunderbird itself, but it was empty. I deleted that folder and then unsubscribed to my other newsgroup and tried to subscribe again but now the "Manage subscriptions" button shows me no newsgroups whatsoever!

I am beyond frustrated by this nonsense. What do I need to do to get "Manage subscriptions" to show me the thousands of newsgroups that exist and how do I make "Get messages" to show me the messages currently on my newsgroup?

I'm using Eternal September to access Usenet. My operating system is Windows 10. The version of Thunderbird I'm using is 128.8.1esr (32-bit).

I am trying to login to outlook with OAuth2. Regular password don't work.

Thunderbird suddenly stopped working for this "att.net" email at the end of July. Per the online support, I deleted the account in Thunderbird. When trying to add the account back, the "configuration found in Mozilla ISPDB" worked, but now gets an authentication error (probably wrong configuration) when I try to add it back in.

I can reach my att.net emails directly (account login and password work), but Thunderbird will not activate or access this ATT.NET account. (My other Thunderbird emails are working.)

Please help.

got a new PC, trying to add my email accounts to thunderbird. everything is working except for my hotmail account. I have tried reinstalling, changing settings etc. I removed my account from thunderbird on the old PC tried adding it to the new pc and I just keep getting this error "Exchange auth error" I cannot change the 02uthentic type as i cant add the outlook account. I have no problems adding it back to the thunderbird on the old pc. I have changed my password 4 times thinking it was the problem but nothing. this is what i get everytime.

I have signed into the web and made sure the "imap is on to allow other apps, programs etc" still get nothing. I downloaded the thunderbird app to my phone to try and i have no problem adding my hotmail account. it's only on this new pc with thunderbird, both tunderbirds are the same build# 140.2.0 on both new and old pc.

any help would be awesome, thank you

I've been using Thunderbird on a Windows machine for years. I now have an iMac and recently downloaded Thunderbird to start transitioning over. When I try to set up an existing Email address, the configuration is found in the Mozilla ISP database. After I enter the password though (mobile.charter.net), I get an error stating "Unable to log in at server. Probably wrong configuration, username or password". The password is correct and works on the Thunderbird version on the Windows machine. I have multiple Email addresses and I get the same error on all with verified correct passwords. Any help to correctly install would be greatly appreciated!

Current Behavior When Firefox is set to offline mode (File → Work Offline), the Developer Tools Network tab does not display request body of requests that web applications attempt to make. This creates a significant gap in debugging capabilities, as developers cannot inspect request payloads details that would normally be visible.

Requested Enhancement Enable the Network tab to capture and display attempted network requests payload even when offline mode is enabled

I have been unable to send or receive emails for the last two days. I use an up to date Windows 10 and Thunderbird version 128.9.1 on a Lenovo ThinkPad X1 Carbon laptop. I've tried running "Thunderbird in Troubleshoot Mode ON" with and without starting "Windows Safe Mode With Networking" and it didn't solve the problem. I tried with Microsoft Firewall and Microsoft Defender antivirus ON and OFF, and with NordVPN ON and OFF, and still no luck, with or without Troubleshoot Mode ON. I enclosed the Connection Settings, Firewall Settings and SMTP Settings and Microsoft Defender Version. I receive and can send emails via other software like Bluemail or EdisonMail for Android phone so my server and email provider are working fine. Can you help, please?

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking

Firefox 134.0.1 (64-bit) Windows 10

I am trying to use the Thunderbird mobile app on my Android device. I tried generating the QR code on the desktop app and scanning the QR code with the Thunderbird Android app, but the QR code never gets scanned; it is not getting processed.

Since upgrade to 128.10.1esr, list of emails in local folders is visible, but cannot view email contents, cannot forward, cannot reply, cannot move, cannot delete.

IMAP folder functionality is all OK.

Occurs in both 64 bit and 32 bit versions of 128.10.1esr

After this occurred on 64 bit machine, we had 32 bit two machines running a previous version of Thunderbird that were still able to access (read, forward, delete, etc) emails in the same local folders (local folders are on network and accessible to 3 different computers).

After upgrading one of them, access to emails on local folders broke on that one, but still working on remaining machine running older version.

This means it is not corruption of local folders (e.g. folder repair and .msf deletion don't make any difference).

It seems to be a problem with this version since update.

How can this be fixed, do we need to wait for another update?

Hi. I have a Dell Inspiron, it’s a few years old, and my computer is running windows. Today I was on a website, doing my assignments as usual when randomly the internet stopped working on the browser (I was on the web for about an hour before this). There was no change to my behavior, I had been on the same site for the whole hour, and had been interacting with the site during that time. My computer still says it’s connected to the internet, and I was even able to play an online game on my computer that I had downloaded, so it looks like my computer is connected to the internet. I’ve tried to clear my cache and open private windows but that didn’t help.

How can I move emails within Thunderbird? I want to move emails from the Sent folder of my old email account to the Sent Folder of my current email account. Emails don't move when I right-click on them and select "Move to" and then select the destination folder. All that happens is that the Thunderbird status bar reports: "Looking up pop...." "Connecting to pop..." "Connected to pop..." "Checking mail server capabilities."

I currently have version 12.1 of the Thunderbird Android app. A few weeks ago, the app stopped showing messages in IMAP subfolders. All messages that were there disappeared from view. The messages can still be viewed in the Thunderbird Windows desktop program and in the K-9 11.1 app.

Using Thunderbird desktop for Windows with my Hotmail account, I frequently cannot send an outgoing email. I regularly get the following message even while successfully receiving incoming messages.

Send Message Error Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Cannot connect to SMTP server 2603:1036:308:2817::2 (2603:1036:308:2817::2:587), connect error 10060.

I use Thunderbird for Android with the same email account without any issues. Any thoughts?
