Thunderbird Community Forum

I became a THunderbird user recently to help me transfer e-mails from one system (e-mails sent to my e-mail address being collected by Gmail using POP3) - I have a gmail.com address too which shows all the e-mails in the same Inbox. Google are withdrawing support for Pop3. I am moving to Hostinger which happily collects and displays all my emails on its Webmail service. Thunderbird is a great tool for moving e-mails fro Inbox (and al other folders) from the Gmail to Hostinger. But yesterday it crashed and wouldn't restart = white windows says at the top 'not responding = and Windows Task Manager shows me Thunderbird still seems to be talking to one of my accounts and has 6 other tasks open. I stopped those tasks and closed Task Manager. I have uninstalled and re-installed but it comes back with the same symptoms and same tasks running. How do I stop this and get it back properly again

I have got two e-mail by Thunderbird : d.nadal@orange => OK but danielle.nadal@kohinos.net NO connection Thunderbird said : connection time exceeded'. What to do?

Maybe a red herring: I was in the middle of doing a Documents folder backup when I decided to open Thunderbird for some reason. Got an Unable to Load Profile type of message. And my attempts at a fix seem to just send me further down a rabbit hole. I started out by renaming my profile.ini file, but I really didn't know what the heck I was doing and possibly caused more harm than good. Then I tried to find my profile file/folder itself, using the Thunderbird > Troubleshooting > Profile Folder path and doing an import from inside TBird but that ended up with various problems such as drilling down to the profile folder from within TBird but then when I clicked Select Folder in Thunderbird, that didn't trigger any sort of import.

I also spent a good deal of time trying to find my AppData folder, finally being able to view it (a hidden folder, apparently), and saw several recently-dated profile types of folders, but again, I couldn't manage to "hook up" any of those folder/files from starting inside TBird and selecting Import... I ended up just stuck inside a folder, not triggering any Importing activity.

Finally I found a profile folder (5yed...) at a higher level on my PC than inside that long AppData Roaming Thunderbird path. THIS profile was inside: D:\DOCS\Thunderbird\Profiles

Now THAT folder I managed to get an Import to trigger. But the result was an Error Message telling me to go find my Error Console. Can you please see the attached Error Code display screengrab and tell me there's hope that this was at least the right file but just poor results that I can fix somehow???

The following is my copy/paste of the text I see in the Error Console display that's in my screengrab after trying to import the above 5yed... profile, in case it helps you see it better:

Also attached below are also:

• a screengrab of a set of profiles I found, but when I drilled down to them from within TBird's Import selections and clicked Select Folder, as far as I got was an open folder, or something like that.
• Thunderbird's Troubleshooting Info "Profile Folder" path.
• Message telling me to see the Error Console. The message appeared right after I tried importing the profile that's stated in TBird's Troubleshooting Info "Profile Folder" path.

Here's the copy/paste of the Error Console message display after my try at importing the profile that is in the path that TBird's Troubleshooting Info page "Profile Folder" states (maybe it's the same as my 5yed...profile import try's Error Console display, dunno:

Thanks for any help in getting through this.

1. Was able to receive emails sent to my address xxxxxx@xxxxxxx.free-online.co.uk, but unable to SEND my replies. Was getting this notification: 'Send message error. Sending of message failed. An error occurred while sending mail. The mail server responded: Unknown sender. Please verify that your email address is correct in your account settings and try again, OK' (see attached). 2. Checked all settings, all correct as used to be before the problem started. 3. At some stage, I tried changing the password in Settings > Privacy & Security > Passwords > Saved passwords > Saved logins to see if that helped. It didn't. 4. I removed the free-online Server from the Saved logins (Provider: smtp://relay.free-online.net, User: xxxxxxx) with the intention of restoring it with a new password - but found I couldn't restore the free-online server. So I decided the best thing to do was to restore the password as it was before and to ask for help here. I will have to check on the webmail until the problem is resolved.

NB1. Free-online is a sub section of Plusnet. NB2. Last year I received an email from Greenby saying something about maybe taking over from Plusnet and that I would be notified if and when I had to do anything. I have not received any such instructions so left things as they were. Many thanks for your help from a not-very-techy so stressed old lady.

Dear people,

problem: threaded view is enabled > when the child has a new message, the top message is not bold but only underlined. Without opening the thread, I wouldn't know that there are messages in the thread.

Example: Actual default style: In the view, it appears like this > Thread top message

v Thread top message

  - Old Child message
  - New Child message

The style I prefer: In the view, it appears like this > Thread top message

v Thread top message

  - Old Child message
  - New Child message

(see also screenshots for that).

As the solution in https://support.mozilla.org/en-US/questions/1265223 did not work anymore (since starting with Thunderbird 115+ the message list was rewritten from XUL treechildren to a HTML-based table view) I wanted to post another solution if someone stumbles upon this problem via google.

1) Enable customized stylesheet support: a) ☰ Menu → Settings → search for config → Config Editor b) Search for "toolkit.legacyUserProfileCustomizations.stylesheets" and enabled (set it to value "true") it by double clicking

2) Edit the Thunderbird styles by adding your customized stylesheet: 1) Help → Troubleshooting Information → Profile Folder → Open Folder 2) Inside that folder, create chrome/userChrome.css (folder name and filename must exactly named like this; pay attention to not create a userChrome.css.txt by accident when using an editor) 3) Put this into the userChrome.css: /* Collapsed thread that contains unread messages → bold */ tr[is="thread-row"].children[aria-expanded="false"][data-properties~="hasUnread"]

 .subject-line span {
 font-weight: 700 !important;
 color: #000000 !important;

}

/* Keep correct color when selected */ tr[is="thread-row"].children[aria-expanded="false"][data-properties~="hasUnread"][aria-selected="true"]

 .subject-line span {
 color: var(--listbox-selected-text-color) !important;

} 4) Save the file and restart Thunderbird

Please Please Please advise how to modify settings to stop copying emails to "All Mail" folder. There are nearly 14K emails in that folder, and it's killing my capacity, I'm getting warnings, etc. Yes, I'm using Gmail.

Yes, I have unsubcribed from it, starting from my account name → Subscribe → unchecked [Gmail] All Mail. To no avail...

Of course, I do not want to delete mails I have saved in my hundreds of other folders. My mail goes back 25+ years, and I want to keep those archives.

Thank you Thank you Thank you!

My Thunderbird crash whenever I tried to "save as" an email, save the attachment of an email, attach a file to an outgoing email.

Every time I did the mentioned, Thunderbird prompts the normal window of my laptop's folders, but it disappear in a second with the Thunderbird crash and quit.

This situation happened after I installed MS365 on my laptop.

I did try the below: 1. Reset attachment directory - mail.compose.attach.dir 2. Run in trouble shooting mode 3. Repair folder index 4. Clear cache

Anyone can help please?

Something horrible and time-consuming has changed within this past week to Thunderbird. My version is 140.7 1esr 64bit. Over the past 4 days or so, I've found I cannot scroll down and see the full emails--until I have to use this new pop-up system.

This is definitely not an improvement in my estimation. Is there any way to undo this?

Subject: Persistent SMTP block on specific Outlook account (IMAP functional) ​Problem Description: Systematic failure of outgoing emails via SMTP on Mozilla Thunderbird for the address redacted@outlook.be. Crucial Note: Incoming mail (IMAP) works perfectly with the same credentials, proving that the authentication and the password used are correct. ​Technical Data & Actions Taken: ​SMTP Configuration: Server smtp.office365.com, Port 587, STARTTLS (or port 465 SSL/TLS). ​Authentication: Using a 16-character App Password generated after enabling Two-Step Verification. ​Symptom: Systematic rejection of the SMTP connection (Command Error 12 or timeout). Other Outlook accounts configured on the same Thunderbird client and the same internet connection (Belgium) are working without any issues. ​Tests Performed: Complete purge of Thunderbird's password manager, alias verification, and full restart of network equipment. ​Conclusion: Since the reception service is operational and full access is functional via Webmail/Outlook App, the block is specific to the SMTP protocol for this particular account on the Microsoft server side. ​Request: Please lift any security restrictions or reset security flags for the SMTP service on this specific account.

My husband and I use the same internet provider activ8 and access it through Thunderbird. I have a new computer. Received a configuration code from Activ8 and I can receive emails but not send them. Get the message PEER USING UNSUPPORTED VERSION OF SECURITY PROTOCOL. THE CONFIGURATION TO MAIL.ACTIV8.NET.AU MUST BE CORRECTED. How do I do that? Activ8 says they can't help.

Reguarly with some month between I can´t send email. After many days, which is impossible to use, it is ok without doing anything.

Haven´t manage to send in many days and now it is huge problem.

When I click on send buttom on the email come text about the fail which is 100% wrong.

It say: An error occurred while sending mail. The mail server responded: (then come my email adress): Sender adress rejected: not owned by (the part of my adress in front of @) Please check the message recipient (my email adress) and try again.

This text is 100% wrong because all things is as always! Never changed it. And seeing it in setting it like it should be!

I am almost given up, this come always with months between and that is hopeless.

Please help!

My computer suddenly started the above error message for multiple programs. The local computer shop was able to sort out what appeared to be the root cause and that recovered some things but I still needed to reinstall a number of programs.

The program I am terrified of reinstalling is Thunderbird. All my emails on five email accounts since 2011 are stored in TB and I naturally do not want to lose any of them.

The major problems are the computer is running Win7 Enterprise and I am 82 years old so I am prone to needing things spelt out in greater detail than many others.

Can anyone provide a way to reset the program permissions (preferable) or identify the best way to reinstall and still access all my historic emails?

Thank you

I am using Thunderbird 115.18.0 and Windows 7 professional (no snarky comments please).

All has been working fine for years, but in the last few days, strange thing have been happening:

In the pane with all of my email accounts, the ">" icon to the left of the first account has been disappearing. This meant I could not look at any folders, including Inbox, Drafts, Sent etc and handmade folders. Cured by closing and opening Thunderbird.

I now have two Archive folders, one called Archive, the other Archives. Both empty, neither can be deleted.

Periodically, when the ">" is present, selecting it (to "V"), the list of folders SLOWLY appears, one folder at a time.

Periodically, the bottom of the Thunderbird window, shows a 'downloading' message, of hundreds of files. Several GB of data has been downloaded over a couple of days.

Opening the Inbox folder, the pane with subject, correspondents, date etc has changed the sort order.

Sometimes, all of the emails in this pane have had their font underlined.

Nothing on my system has intentionally changed,

Any ideas what has gone wrong, and how to put things right would be appreciated.

Thanks,

Does TBird support plus addressing?

Scenario: I want to reply to email sent "To: markfilipak+joe@...". To do that successfully, in the "Write" dialog, I have to click on "From", scroll down to "Customize From Address...", click it, and add "+joe". (There is a menu alternative: "Options","Customize From Address...".)

If I forget to do that, then my reply does not have "+joe"; it goes out "From: markfilipak@...".

The Issue: When Joe replies to _that_ message, it does not have "+joe", so Joe's reply is trashed. (It's trashed because a filter I wrote automatically deletes messages that do not have "To: markfilipak+<something>@..." in the header.

The sensible way to handle plus addressing is for TBird to recognize plus addressing and to automatically make my "From" header from Joe's "To" header. That way, "+joe" will always be there.

Is there a way to do that?

Thanks Folks! -- Mark.

I had two Thunderbird apps on my computer. When I realized that one of them was for organizations, which I don't belong to, I deleted it. But both of the apps were deleted. I then reinstalled Thunderbird, but when I went to send an email, my entire address book was blank. How do I retrieve it and reinstall it ? Thank you.
