With my Pixel 9a Android 16, I installed TB Android mobile by the export/QR code method. The settings were imported into the phone from my desktop, Win 11 TB version 147.0.1 and yahoo.com for my email service. I went through setup successfully, however, when I tried to sign in I receive an error: Oauth sign in failed. Oauth is currently not supported with this provider. Retry does not solve the problem. On my phone the settings are: Server is: pop.mail.yahoo.com Security SSL/TLS Port 995 Oauth 2.0 my user name @yahoo.ca These are the server settings on my desktop as well. Next step in the setup is to "Sign In". I immediately get the "Oauth not supported with this provider" error. I tried IMAP, same error. Under Oauth 2.0 there a pull down menu with: Normal password, Encrypted password or Client certificate. I'm not sure what these options are or if I can use them, ie with my Yahoo mail id and pwd. I tried IMAP server and got the same error. I'm hoping that someone can advise me as to how I get past this Oauth 2.0 error and finish installing Thunderbird for Android. Thank you

Hi,

Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.

Details:

Account type: IMAP (Cogeco)

Happens in all folders

Inbox has ~600 messages (not large)

Was working normally before the recent update

Delay occurs every time moving a message from Inbox to another folder

No freezing — just a delay before the move completes

No antivirus changes

Issue started immediately after update

This appears to be related to IMAP sync behavior introduced in 140.x.

Has anyone else reported this, or is there a known regression?

Thank you.

I believe since your last update, every time my phone switches a data provider, meaning goes from cellular data to my Wi-Fi or vice versa. Or if you go to airplane mode and then come out of it I get the Gmail authentication error. Every single time. I'm running Samsung Galaxy s23 running the latest version of Android 16. Has anyone else had this issue? I find it hard to believe that I would be the only one. It's getting really annoying having to keep clearing it or going in and then when you go into go through the settings it tells you it doesn't work. Any help would be appreciated.

Hi,

I host a autodiscover config (config-v1.1.xml) on my local mailserver, when I want to add my local mail account to thunderbird it sees the configuration, but throws an error:

Configuration found This configuration is not trusted.

I host a local CA, and have imported the CA root certificate into the android certificate store. But I don't think this is the problem, because Thunderbird doesn't connect to my imap server prior to throwing the error. (this is working, I can browse the local link without any certificate warning)

This is my config-v1.1.xml:

<clientConfig version="1.1">

 <emailProvider id="home.arpa">
   <domain>home.arpa</domain>

   <displayName>Local email server</displayName>
   <displayShortName>local-server</displayShortName>

   <incomingServer type="imap">
     <hostname>mail.home.arpa</hostname>
     <port>993</port>
     <socketType>SSL</socketType>
     <authentication>password-cleartext</authentication>
     <username>%EMAILADDRESS%</username>
   </incomingServer>

   <outgoingServer type="smtp">
     <hostname>mail.home.arpa</hostname>
     <port>465</port>
     <socketType>SSL</socketType>
     <authentication>password-cleartext</authentication>
     <username>%EMAILADDRESS%</username>
   </outgoingServer>
 </emailProvider>

</clientConfig>

I've tried changing "authentication" to other methods, but this doesn't seem to matter.

Any Idea?

I have just installed Thunderbird on my Android phone and using my desktop Thunderbird exported my email address to the Thunderbird mobile. This worked OK. Just for the record, this is my first time with Android version of the Thunderbird, and I can't find the inbox folder. Could you please guide me how to do it? Many thanks.

When I first open K9Mail 16.0 or after scrolling to the top of the message list, the message does not disappear from the list after I open a message, select move, and choose a folder. The message will no longer be clickable after I do this. However, it will remain displaying in the list until I start scrolling the message list, at which point the list updates and removes the moved message.

Please fix this bug.

Thanks.

Trying to set up thunderbird for android. I use yahoo mail for my ATT accounts. I get the following message when trying to set up Thunderbird for the first time, "incoming server settings failed. Authentication error. LOG IN invalid credentials" I updated my email password and still have the same problem. I do not have thunderbird on a desktop or laptop, or anywhere for that matter. It accesses my gmail accounts just fine. Please advise.

I have used Thunderbird on my desktop PC for many years, and have now installed it on a Lenovo tablet running Android. The setting up was simple (thank you), and I am receiving emails with no problem. I have tried sending emails and they are simple to type up, but there is no visible "Send" button. I have accidentally sent an email successfully, but have no idea of how this came about. Please help me to send emails, as I am very keen to use the tablet fully. Many thanks, Nigel Olliver.

How do I make Thunderbird the default app on my Android 14 phone? It is not in default apps or in the settings menu in Thunderbird on in Apps under the Android settings.

Thunderbird Mobile (for Android) is missing support for iMIP/iTIP (calendar invitation) response emails. For context I will add that in Thunderbird Desktop when a calendar event attendee has responded to an invite the resulting email message shows a highlighted text about the status of the response. There is also a button to either update the event when the response has yet to be processed or show the details of the event when it has been already processed. This capability is missing in Thunderbird Mobile (for Android). Please add it to the feature list as it annoying to have to lay hands on a laptop just to update a calendar event. Thank you.

Hi, I just started using Thunderbird for Android and - so far - I am loving it. One thing I cannot seem to figure out is how to change the color scheme of the widget. Is it even possible to change it? I would like to set it to use the same dark theme I have for other widgets, but the Thunderbird widget stubbornly keeps its white background.
