Hello. In Thunderbird 128.10.1esr (64-bit), when I click on an email to view, and that email has an attachment, an error pop-up occurs that says "No Apps available" and "No apps installed that can open..." This occurs for the number of attachments I happen to have in that email. So 3 attachments, 3 pop-ups.

First, I haven't even tried to open the attachment yet, I'm simply viewing the email. Secondly, if I cancel out the error pop-ups, I can still open the attachments in my default programs.

Any help on how to fix this (or turn it off) would be greatly appreciated.

I have not installed older versions of Thunderbird to see if it would go away, though I suspect it eventually could as I didn't always experience this. I did also update my Linux distro fairly recently, but it was after this started occuring.

I'm using Linux Mint Cinnamon 20.3 and flatpak to install/update Thunderbird

As of today, I can neither send nor receive email for my imap accounts - imap.gmail.com and imap.mail.yahoo.com. I have Thunderbird 128.9.1esr(64 bit). They both work outside of Thunderbird. Notification reads: Authentication failure while connecting to server ... where ... is each url above.

I have Version 128.5.2esr (64-bit), it says it is up to date.

So I've been noticing a couple of days now that I can no longer view messages in the message pane to the right of the screen. When I click on an email in the list on the left, the top of the pane on the right shows me the To, From, subject etc, as well as a yellow bar saying "Warning: To protect your privacy, Thunderbird has blocked remote content in this message." Then, nothing underneath this. Where it used to show the email contents. I do NOT want to have to double click every single email in my inbox to look at them in a separate tab. Most of what I get is not useful. I want to be able to click once and preview the email, then click Down to check the next one, and on and on the same as Thunderbird did it LAST WEEK.

Can someone help me get it back to working please? Thanks!

I recently posted a request for help which was; Hello, All of a sudden when turning Thunderbird on, I have found that all messages in my Inbox have gone ( except a few for last day or two). Looking around Thunderbird I have found all Inbox emails have bee dumped into my Trash folder! Please help - how can I get emails back where they belong and get Thunderbird back into working order? Very grateful for any help' Thank you, kindest regards Brian Benger PS where will I get your reply if my email not working??

I had two replies, one was from Wayne Mery who asked what version of Thunderbird I was using, my answer to that was 128.10.0est(64bit). the second message failed to transfer from my mobile to computer because I suspect to my problem above.

So sorry to reply like this I could not find how to reply to very kind replies I received Kindest regards, Sprite (Brian)

Does Thunderbird have a list on the number of members you can add to create an email group. I seem to only be able to add 7. Is it possible to create a larger group - e.g. up to 50?

I have downloaded the app to tablet and phone and all I get on both is blank white screen for unified inbox phone is Samsung a52 tablet is android 15

Hello, for the last week my Thunderbird android is no longer sending mail.

I revoved and add it again my mailbox. On the SMTP validation I receive this error message: Unexpected end of string

Setup is not finishing.

When I try to add a new email account, I'm told that either my username or password is incorrect. This isn't true. I can log on to webmail using the same credentials.

How can I solve this problem?

I installed Thunderbird 138.0.1 (64-bit) on a Win 11 desktop computer yesterday and the column headers for the messages are not displayed. I have View/Headers/All, View/Layout/ Classic View, Folder Pane, Message List Header selected. How can I get access to the message column headers to display them and later select the ones I want ?

Thanks, Corey

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?

After update 138.0.1 my profile is not "opening" emails.

I can see that im getting emails, i can see that i can send and make new emails, but the emails when i either click or double click them are "white".

I even tried reading the "source code" it shows nothing. I even tried going to the beta channel, but no avail, the issue persists.

Is there a cleanup, any file to delete? something?

Headers are inconsequential, compared to the actual message content, I'm sure everybody will agree!

But on Thunderbird, recently, the headers take up almost HALF of the available space on the screen!

I have tried everything to reduce the message headers to ONE LINE (that is all it needs) but nothing works!!!

Have a look at FoxMail (screenshot below)! Compare it with how my Thunderbird looks (screenshot below)!

These are actual screenshots of what my entire screen looks like, with Thunderbird and FoxMail.

Foxmail has clean, simple, one line headers, with the message body taking up the maximum viewable space on the page! Thunderbird is almost 50% WASTED screen space!!!!

BTW the add-on / extension "Compact Headers" does not seem to work with the latest versions of Thunderbird.

Thank You!

I used to have an icon to change how the message list was displayed, and in particular it allowed me to sort emails into either threaded or unthreaded. It was next to the icon used to select columns to display, in the top right corner of the pane. It's disappeared and I can't find out how to get it back - can anyone point me in the right direction?

Hello,

I have settings set in account settings to apply signatures on replies and forwards, however it is not happening. What else can I change?

Thanks, Taylor

I've setup a filter rule to auto-reply to emails while I am on holidays and this works well. However, there are some businesses who will continue to have me on a cc list or in a team distribution list.

The idea is to only send an out of office reply once. I think Outlook does that from memory.

Is there a way to do it in Thunderbird or is this currently not do-able within the Thunderbird base product or via extension/addon?

Running Version 138.0.1 64bit.

Starting this morning, only one of my three Earthlink email addresses I have set up in Thunderbird is downloading email from the Earthlink POP server. I have verified there are messages using the Earthlink app and web mail. It seems to contact only that one email address host and not the other two. It seems it is not even looking for messages to download on the other two. If I right click on the email account in the left bar and select, "Get Messages", nothing happens in the bottom status bar for those two, but the third shows it contacts the server. All worked fine just yesterday. I am running Windows 10 and Thunderbird Portable. I am using McAfee AV. What can I do to get those two email accounts to work with the server again? Thanks!

Thunderbird used to save emails with html formatting etc but now seems to only save text- that is when saving as a file. Is there a way to save emails with the html formatting intact? Thanks

I am being flooded with SPAM emails as of Jan 1, 2025. I mark them as JUNK and Mozilla seems to not understand they are junk and continues to fail to block them. Also, ALL of my incoming emails are now being delivered to the TRASH folder instead of to the Inbox folder.
