Thunderbird Support Forum

A while ago I subscribed to an RSS, but all that happened was that two empty folders were created and they're impossible to delete. They just return. I run the latest Thunderbird on an updated Windows 11 PC.

First of all, Thunderbird for whatever reason does not trust Lets Encrypt certificates. Is Thunderbird special?

Next, when it asks to confirm the cert, the confirmation dialog and a message box appear, hidden under the new email window. Is there a good reason why they should not pop up, like all normal new dialogs and message boxes pop up, in millions of other softwares? Does Thunderbird have to be special and hide its dialogs?

And lastly, it takes a deliberate development effort to hide new dialogs. Is there a good reason for you to do that to us, so that we have a hard time Alt-Tabbing into the confirmation dialog? What is it?

This just started recently, and I have no clue yet how it started or how to fix it. I have tried several "fixes" listed on the internet, but no luck so far. I'm running Thunderbird V 102.5.0 (64 bit) on Windows 11. This does not happen to any other programs that I may be running, only TB and only after I delete the 2nd or 3rd email in my sbcglobal account. It doesn't happen with my gmail account that I have running in TB also. The freeze lasts a couple of minutes, and then reoccurs after I delete 2 or 3 more emails. It seems to only affect my "inbox" and not "sent" or "trash". Sorry if this has been asked and answered before, but I was unable to find it here. Would appreciate any assistance to point me in the direction of a solution. Thanks

Device: Desktop computer - Win 7 Pro Email client: Thunderbird Version 102.13 Server: POP settings

I am a Cox email user and was recently migrated to Yahoo. After I input the correct server settings on the Thunderbird app,each time I click on the Get Message button, It starts downloading all (100K+) the email messages in my Yahoo inbox, including the ones that were already downloaded on my computer from the Cox server. Are there certain settings in Thunderbird that will stop this issue and just let me download new messages? TIA -Craig

I am using Thunderbird 115.12.1 (64 bit) on Windows 10 with the email account set up as POP3 for the Gmail account

I have a subfolder under an Inbox (Gmail account) that is no longer showing up. If I search for an email address from a sender that was in the folder, I get a list of emails showing the dates and subject, but if I click on the email, the tab that opens is blank.

My PC crashed, but I can't say for sure when the folder disappeared, other than I know it was there 4 days ago. It the the only subfolder that is missing.

Any help is appreciated. Thanks

To the Mozilla Community:

I have a Posteo account and set it up successfully in Thunderbird. Emails and Calendar are both working without any issues.

However, Posteo contacts are not syncing. I used the TbSync / Provider for CalDAV and CardDAV without success. And using the Add CardDAV Address Book in Thunderbird is not working either.

Posteo Support confirmed my settings are correct. (Enter https://posteo.de:8843/addressbooks/johnexample/default in the URL field and replace johnexample with the local part of your email address. )

Any assistance that can be provided to troubleshoot and resolve this issue is appreciated.

Thank you.

Please explain how to resolve this issue. Unable to send email from fwinters@comcast.net. Error code resomata-a2p-646965. sys.comcast.net

I just updated to version 115.11.1 and now if I delete a message in my unified Inbox, sometimes it deletes and quickly comes back and sometimes it just stays there and I cannot delete again (delete is greyed out). Sometimes it does go into trash but still shows in inbox. In my server settings for that email I have the deleted email set to go to trash for that inbox. Suggestions?

I might give you more info..it seems now if I delete the message either by right clicking or top menu delete, it sends to the trash but stays in the inbox (sometimes it goes away but comes right back). If it stays in the deleted unified folder and I empty that trash folder it comes off the inbox. I have W10..and mail is from Yahoo Cox conversion that was working fine until this update today. Yahoo does seem to be much slower than Cox was so I am trying to be patient and wait but it stays in the inbox until described. The bottom taskbar icon still shows a mail in the inbox too even though it is in trash or even emptied. I have to close TB and go back or say to close window for this new mail icon to clear.

I have also discovered if i send an email from my iphone, eventually it comes into TB but if I delete it on my phone it is gone in TB but is NOT in TB trash but it does eventually show on my iPhone trash...the only way i could see this is to remove Trash from that email account in the unified section and then it shows in the regular trash for that email...seems maybe the unified folders have issues after this update ..this is getting so frustrating...and surprised there has been no response to this help question either..I checked my email here and it is correct..

I have been using Thunderbird for years and love the program. I was surprised today when I was writing a long email and the cursor kept ending up in the Subject heading instead of the body of the email. My typing continued in the subject heading. I had to manually move the cursor back to the body of the text. I noticed this happened every time the email was automatically saved. It was very disconcerting to be looking at my keyboard then whenever I looked up, the text kept appearing in the subject heading.

There is obviously a bug in the software and the only answer I can figure out to fix this until it is corrected is to disable the Auto Save function. How do I do this?

I would report this to anyone interested in resolving bugs in Thunderbird, but I could not find who or how to contact the developers.

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

Ever since the Cox-Yahoo migration I am finally getting emails in TB (few glitches). but emails/changes take several minutes to appear/update on my iPhone . My iPhone only option is for Fetch and the time is 15 Minutes..so I have to open the MAIL app and it will look for new/updated messages but it takes a good 2-3 MINUTES to appear. And if I delete a message on TB sometimes it never updates..any suggestions?

When I select "Sent" emails to review to see what I have sent. I find that Thunderbird will not show emails with attached files. (see image) To see what I have sent with attachments I have to select attachments. (see image)

I would think that I should see ALL the emails sent when first selecting "Sent".

I then should be able to view only sent emails with attachments when I select attachments.

Are my settings off or is this a bug in the software?

Let me know. TY

Can't use Gmail account anymore have cleared cookie's and caches removed permissions and account from Google and TB uninstalled then reinstalled then add TB account worked for 2 minutes then got the same error also some emails load while others are just a blank screen all windows 10 and TB updates are current Have attached error we are receiving anything else please just ask Any help appreciated

Starting 3 days ago: Cannot SEND email - receiving works fine. Error message: An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The other odd thing is that I get asked for a password before sending which never happened before.

I followed advice given someone in 2022 - I've messed with the account settings (unfortunately) and I've changed the SMTP settings to match what Comcast recommends.

I have 3 comcast accounts; two work fine on my iPad and iPhone - one doesn't

Also I have no problem sending emails using Xfinity/Comcast Mail... but I want to use Thunderbird.

Where do I start looking?

Thanks!!

I'm sure I've made the problem worse by trying to change the setup

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

Hi,

Thunderbird suddenly stopped working today,, can not receive emails or send emails. I can log directly into web client and emails are sitting there have confirmed settings with my hosting company and everything is working their end they have also confirmed the settings are correct in Thunderbird

It has been one year, and you still have not fixed the multiselect functionality that was ruined with your Supernova "update" (which is worse in almost all aspects btw). Can you at least tell us WHEN you plan to release the fix since you locked the comments to block the countless negative ones? Is it so hard for your UX team to understand that removing multiselect functionality is like removing Ctrl+C, and Ctrl+V and set the correct priority???
