Got Thunderbird on 2 machines and both have the same issue. I did try running only one at a time and still I cannot fix it.

On a Yahoo! mail account I deleted a "Draft" folder and it was sent to Trash. If I empty the trash it's gone until I either click Subscribe... and refresh the folder list or reopen TB. Then the folder comes back into Trash. I can't get rid of it.

I logged into the account via their web-based interface and checked my folders. The folder I deleted is indeed no longer there. Not in Trash. Nowhere.

I'm not referencing it in the account either. The option to save drafts is set to the "Drafts" folder, not the "Draft" folder.

I configured the folder properties to be neither subscribed nor offline. I then went to "server settings" and checked "show only subscribed folders" and unchecked "server supports folders that contain sub-folders and messages".

I shut down TB and relaunched it. Folder still comes back. I then shut it down again and deleted any references from the profile's folderTree.json, folderCache.json and the corresponding .msf files. I start TB again, folders still come back.

Then on two AIM accounts I have again phantom "Draft" folders in each. They're unchecked from sync and offline availability. Again I go to "subscribe..." and uncheck them. They don't disappear. I have "show only subscribed folders" checked and still the folders show. I then click Refresh in the subscribe dialog to reload the folder list. They're all checked again.

How do I get rid of these folders? Particularly bewildering is the Yahoo! case where I've explicitly told TB that the account server does not support folders within folders, I don't understand how it can read anything client- or server- side and still reach the conclusion that it needs to restore a "Draft" folder in Trash.

These issues are happening exactly the same on 2 different Windows machines both running TB, affecting the same accounts.

I know I can set Firefox to offline mode by pressing Alt on my keyboard and choosing "Work Offline" from the file menu. However, the browser doesn't actually seem to show me cached versions of sites after I do this. Instead, every site — even sites I visited literal moments before switching to Offline mode — shows me the same "Firefox is currently in offline mode and can’t browse the Web" message, and invites me to "Try Again" to go online. But I don't want to go online. I want to see the version of the site that, I hope, at least if Firefox behaves as I'd expect it to be have, is already saved in my computer's cache. How can I achieve this?

I have been running Thunderbird for almost seven years now, and these behaviors have persisted since day one on my laptop and desktop computer. First, I have five accounts set up. I am running two add-ons (Provider for Google Calendar, and Quicktext). I am currently running a snap version 115.12.2 of Thunderbird on both machines and they both are running Ubuntu 22.04 LTS. Plenty of RAM and plenty of free disk space.

Here are the two issues...

1. More often than not, when an email comes into one of the inboxes and I am viewing the unified inbox there are two copies of the same email. If I switch back to the actual inbox of the account it only shows the one. This is very aggravating and when you start trying the delete emails from the unified inbox it gets all hosed up and I end up having to go to each individual mailbox to delete the messages.

2. This somewhat relates to issue one... Sometimes when an email is deleted from the unified inbox, a blank record remains like in the image. This shows only one but sometimes there are multiple ones. Of course, if I go to that message's inbox it is not there.

I have tried all the common things like deleting the index files to let the indexes rebuild, comparing folders etc., and again, this has been a persistent problem since day one. Any insight or solution would be greatly appreciated.

Thank you! Mike

System specs below. Thunderbird is set with 1 account: A paid Yahoo email, with a LOT of messages (well over 36K), using IMAP (Yahoo only lets the most recent 10K come down via IMAP, sadly). Most emails do download and are correctly rendered. But around 10%, starting usually a month or so back from the high water mark of last update, show email source code (text of headers, mimeparts, etc.) for a totally different email than the one highlighted (a few days later, different sender, etc.) Checking the message on Yahoo, it renders correctly. There is no pattern to the corrupted messages: they can be from mailing lists, company marketing mails, an alert from my local town, whatever.

Once the error occurs, it is consistent across Thunderbird shut-and-restarts (still showing same wrong email source as before). Emails to either side (earlier and later) render properly in the message pane.

Double Clicking the message to it's own child pane renders a pane with Subject and From as blank, and the same email source text for a different email. Forwarding the email puts the email source code in as text (I was hoping the act of refreshing and reformatting might grab the correct content, but no).

Doing a Repair Mailbox (which seems to mean "download headers again, then download all the mail again" does seem to correct for a time (including the previously corrupted emails now rendering correctly)... but within a day or two, a new crop of messages will be corrupted, and the dance starts again.

Windows 10, 64 bit. Norton 360 set to exclude all mailbox directories. Thunderbird 115.12.2 (64-bit), though this has been happening since 110. No plugins, no extensions.

Are there diagnostic logs or other info I can share that can help us figure this out? I really like Thunderbird, but it's just unusable here. Outlook, Apple mail, other tools don't seem to have this problem.

I have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?

When I try to forward an email, I get the response: Sending of the message failed. 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 above response was when I tried to forward to another account of mine - both from comcast.net

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

Hi

This has only recently happened but PDF comments are no longer displaying in OWA365 when using Firefox. I can open the same email in Edge and they are displayed fine. Strangely, if I go to print the PDF within Firefox, I can see the comments.

I've set my Application to open PDF with Adobe Acrobat Reader but this makes no difference. Is there anything else I can try?

I'm using Thunderbird 115.10.1 and Windows 11 Pro. Thunderbird has suddenly started sending my partner's emails to Trash. We've been emailing fine for years before this. She has not changed anything in her emailing. I've closed and re-opened Thunderbird. Her emails are not marked as Spam and I have marked some of them as 'not junk'. Anyone got any ideas? I can't seem to find reference to other people having this problem.

Greetings,

In Thunderbird 115.12.2 (64-bit) on Linux Debian 12.6, when I examine "Help -> About", cursor movement in the focused information window moves the list of messages displayed underneath in the unfocused messages window. Hopefully the image suggests the issue. Is this an OS problem or something that can be corrected in Thunderbird?

Also, I maintain several accounts, each with several folders. It would be helpful if these all stayed collapsed until selected, with a digit alongside indicating the number of unread messages in each, but recently they each seem to fully expand at inopportune times, making email management rather difficult.

Is this the result of a selectable setting somewhere, please?

When I start a email message search, I am bombarded with bad suggestions for email addresses. These include addresses from everyone I've received email from even though I have deleted these entries in collected email addresses and my personal address book.

The addresses could be from old purchases or ebay responses or anyone I've ever received an email from. I have deleted most of the emails entirely, yet I still get all these bad addresses when I search.

Is there a way to clear the history in search or remove the email addresses where I have deleted the email?

I've attached a Home Depot search as an example.

Since December last about every 30 days or so Outlook locks my account. This only happens when I "hit" send on an outgoing message from Thunderbird. A friend has suggested that Outlook sees my outgoing e-mails as spam and when it reaches a critical number Outlook locks my account. Attached is a screenshot of the error message. Has anyone else run into this problem and, if so, is there a solution? Thanks, Ken.

How do i access Google OneDrive via Firefox so as to delete my sensitive personal info such as financial PDFs and personal pics, which involuntarily got copied to Google OneDrive thru an erroneous mouseClick?

See, when i keyword search online, it states that Google Drive can be accessed via one's browser for purposes of accessing/deleting one's files. (Frankly, i don't even know if OneDrive is GoogleDrive? Is it?

It's upsetting to me that Google has loads of my personal info, because over the years everyone has been saying "Use Gmail", and so i made that my main email due to convenience. But Google now has, for example, some of my personal home photo's and private financial PDFs, all because I absentmindedly clicked my mouse on a risky part of my email attachments, not realizing that would transfer the JPG (or PDF) to Google OneDrive.

I believe this started happening ever since they imposed the New Gmail without giving us a choice. Prior to that, when i used HTMLgmail, i don't recall this happening when i clicked attachments. With Simple HTML, if i clicked an attachment, i saw a photo. It didn't INVOLUNTARILY auto-transfer my pics/pdfs to Google OneDrive, which precisely reminds me of automatic faucets and towel-dispensers and light-shutters in public buildings, all of which are human-unfriendly.

My (custom) cursor has recently started being transparent when I hover over a YouTube video. On darker colors it's fine, but on white it's straight up invisible. I tried recording it, but the recording doesn't capture the transparency. This didn't happen before, I changed nothing.

A couple of days ago I had to change my default browser from Firefox to Chrome to fix a problem on a particular company's web site. After I made Firefox the default browser again I found that every hyperlink in an email or a document that I clicked on opened Firefox at the same web page: "https://read.amazon.com/landing".

I have no idea what I might have done to create this situation, let alone how to undo it.

I am using Linux Mint with Firefox, Thunderbird and Libre Office.
