hi, i am trying to remove an email account from Thunderbird app that i added but the "Delete" button in account settings isn't working at all! when i click it nothing happens. i select the account but when i click the delete button nothing happens

In TB prior to v.155, folder message counts were not shown at all if the respective folders were empty. That is, instead of showing "0", TB did not show anything.

Now, after updating to TB v.155.0.1, I see dashes (horizontal lines) in the folder tree to the right of each empty folder.

Is it possible to revert back to the original behaviour and get rid of those unsightly dashes? They only add visual clutter (my opinion, obviously) while not providing any extra information.

Thanks.

I have been trying to set up Thunderbird Mobile on my Android phone. I scanned the QR code to export my settings. However, when I open the app on my phone, the only options I have are "Add an email account", or "Sign in with Thundermail". The instructions state that clicking on "Get Started" should bring up the option to "Import Settings" but it does not.

I've been using Thunderbird version 155.0 with only a few issues (reported in other posts).

To investigate one of the issues I've had to create a new profile for testing. I've managed to set everything up except for my default font for outgoing emails. If I send an email with say, four lines of text, I can format each line to be a different font and the received email reflects the different fonts for each line.

But Thunderbird isn't remembering the last selected font. So if I send a second email (without re-selecting any font) the recipient receives it in some naff mono-spaced font. I guess there's somewhere where I can set up the default font for my outgoing emails but I haven't managed to find it yet. Can anyone help?

Hello fellow Thunderbirds,

I have been using Thunderbird for years and had thousands of emails in quite a few folders, with a shit-tonne of filters etc. My emails were running pretty well. I only use two addresses, but the folders help manage everything.

I just got a new computer last week. Prior to switching over to the new computer I read through the 'Export your Thunderbird Profile' help page, and the 'Move Thunderbird data to a new computer' pages. I've tried to follow all the info there (with a glitch, explained below).

I am using a Windows system and have gone from Win10 to Win11.

I have the following data:

• Mozilla Maintenance Service (in Program Files (x86) ).
• Mozilla Thunderbird (in Program Files (x86) )
• Thunderbird (In Users/Username/AppData/Local/Thunderbird) (Contains 'profile' and 'updates'

I tried to swap the above data into the same spots on the new computer, but alas, it's not working. I *may*, however, have fucked it up myself...

So... When I got the new computer, I immediately downloaded Firefox, but, alas, I entered my email's details before closing it down. It did download a few off the server, but only a day's worth (before I realised I screwed up).

As soon as I realised I'd mucked up, I uninstalled Thunderbird and deleted the files on the new computer (you know how when you download it doesn't always remove all the stuff, so I tried to do this).

I reinstalled Thunderbird, but closed it prior to loading the email addresses on (as instructed). I then transferred all the above data into the corresponding file areas on the new computer. However, everytime I try to run the program it just goes to the standard open screen (with the popup that prompts you to enter your email addresses and details into it - see image, below, in case I'm not explaining it right).

Anyway, I'd appreciate any help you might be able to give me as I'm desperate to get my emails running again and have access to all the saved emails which were in my system. Kindly. Larysa.

Thunderbird comes up as not responding - tab names appear but he last tab is constantly trying to open. This began about 2.00pm Tuesday 15th September. Shutting down & restarting has no effect - please help!! Brian

Anyone know how to use the new setting "mail.addr_book.add_item_default_uri" in 155? The default value is a URI, "jsaddrbook://abook.sqlite", how do I figure out the URI of an alternative? I want to point it to my CardDAV server, do I just set it to the CardDAV URL?

This morning, my email Inbox is empty. I use Thunderbird for four email accounts, and three of them are fine, but the fourth one has an empty Inbox this morning. I didn't (intentionally, anyway) move the emails anywhere, and they do appear to be in the All Mail folder, so I didn't lose them entirely. But I keep my emails mostly in my Inbox and they aren't there anymore.

Any ideas what happened to make them disappear and how I can get them back to the Inbox?

Thanks!

What I see When I reply to an email written in classic Outlook for Windows, the quoted Outlook text gets a big gap above and below every single line, and its font changes. This happens as soon as Thunderbird processes such a message again, for example when I view my sent reply, reply to my own reply, forward it, or reopen a saved draft. Thunderbird users who receive my replies should see the same gaps.

Why it happens (as far as I can tell) - Outlook writes every line as its own paragraph and relies on a small style rule that says "no extra space between paragraphs". - Since version 151, Thunderbird puts the quoted email's style rules into a protective container (`@scope`) so they cannot change my own text (bug 1967725). - Thunderbird's own safety filter for HTML emails treats this container as a suspicious rule and deletes it, together with everything inside it. The "no extra space" rule is lost, and the gaps appear. - Older versions such as Thunderbird 140 ESR don't understand the container at all and ignore the rules even in the first reply.

In short: one Thunderbird feature adds the container, another Thunderbird feature removes it again.

How to reproduce (no Outlook needed) The attached test message contains two quotes with the same spacing rule: quote A inside the container, quote B without it. In Thunderbird 155.0.1 quote A shows big gaps, while quote B stays tight.

What would help Keep protecting my own text from the quoted styles, but in a form that Thunderbird's own filter and older email programs don't remove, for example by limiting the quoted rules to the quote with an ordinary class name instead of `@scope`.

Technical pointers - Filter: pref `mail.html_sanitize.drop_conditional_css` (default true); `NoConditionalRules` in `stylesheet.rs` rejects `CssRule::Scope`. - Container: `QuoteSanitizer.sys.mjs` (Phase 2), called from `MsgComposeCommands.js`. - Tested with Thunderbird 155.0.1 on Windows 11.

I created a POP3 account, and no SMTP config was crested in Thunderbird. So, I tried the Add option and after filling the form the line still did not get created. Current TB version, Win 11 Pro. I have several other accounts that configured OK, all Spectrum.

Thunderbird is downloading new messages but failing to display them.

Other functionality remains active, ie I can see and open messages, delete all the contents of folders, compose and send messages, but when the software downloads new messages they simply do not display and cannot be accessed.

Not sure if it's relevant, but the message INBOX count appears to be stuck at the number 59, although more messages than that have been downloaded.

Bizarrely this is the message displayed whenever I now open the Thunderbird application (it was there when the problem first appeared and returns everytime). Out of desperation I even made a donation in the hope it would release the messages!

Thank you in advance, Steve Davidson

Hello forum,

I have 2 mail addresses at gmx.de. I can’t sign up for either of them for a few days. I get the note: password wrong. I use the same password for both email addresses. I can sign in to both addresses via the browser at GMX, but not in the Thunderbird that I have been using for years. I have always called the two e-mail addresses via Thunderbird. I can't explain a reason for this problem. I hope that's from any of you.

Greetings Dieter

My Thunderbird (windows) is really not working, so I want to reinstall the whole thing. I have 4 accounts and a local folder. I don't want to backup all the profiles before reinstalling, as I am having an annoying issue with g-mail (I don't HAVE a gmail any more, but Thunderbird wants to login to gmail every time I open it). I only want to backup the "local" folder, as, so I want to reinstall the accounts one by one from scratch. In that way I hope, I can purge Thunderbird of the gmail. Now the question: How do I backup the local folder in a way that makes it easy to import it back after all the reinstallment?

Hallo Forum,

ich habe 2 Mail Adressen bei gmx.de. Bei einer von beiden kann ich mich seit ein paar tagen nicht mehr anmelden. Ich bekomme den Hinweis: Passwort falsch. Ich verwende bei beiden Mail Adressen das gleiche Passwort. Ich kann mich über den Browser bei GMX bei beiden Adressen anmelden, aber nicht im Thunderbird, den ich seit Jahren benutze. Auch die beiden Mailadressen rufe ich schon immer über Thunderbird ab. Ich kann mir keinen Grund für dieses Problem erklären. Hoffentlich kann das jemend von Euch.

Grüße Dieter

I use Windows 11 Pro on a desktop computer. I use Firefox (which is up to date) and Thunderbird as my email client (which is up to date). I use Zone Alarm Extreme Security as my Firewall and Anti Virus

Recently it has become a nightmare sending and receiving emails to my markhowes@btinternet.com email address. Sometimes the emails (which I know are on the bt server) don't arrive but I don't get an error message. Then later in the day I might receive loads of emails at once.

Sending emails is even more of a problem. They simply don't go. Sometimes I get a time out message, sometimes I get an incorrect password message.

Within Thunderbird there is an option to check connection to both the outgoing and incoming bt servers. Usually (but not always) connection shows as "successful".

This has been going on for a couple of months - maybe it's a coincidence but it seems to start up after a Windows automated update and then things settle down again (I think) until the next Windows monthly update.

I'm not all that computer literate so please don't suggest messing around with the Registry or other very technical solutions but if anyone can help me solve this maddening problem I would be really grateful.

I can send and receive emails on my Android phone and directly on the bt email site via my Firefox browser.

This morning, I go into Thunderbird, but while I can see all my previous emails and folders, there are none from today. And yet going directly to TalkTalk Mail, there have been some. What can I do?

I have settings from Greenby to set up server connections for a new account. They are validated by thunderbird but, after, entering my greenby password, generates the error, below, which greenby claims is a thunderbird problem.

"Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI] Show less

Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI]"

Now my greenby password works on their systems

Now I'm very new to Thunderbird so not familiar with the commands

Any one any ideas ?

Hi, I found an entry in the "thunderbirdmail.de" forum from 2005, where they discuss the option of using userChrome.css for changing the number of lines in the title of an calender appointment.

My problem is, that if the text of the title is really long, thunderbird will not enlarge the title window (more lines), so I can see the whole text (as in Outlook - from where I just changed to Thunderbird a few weeks ago).

The entry into the userCrome.css (as suggested in the forum)

.calendar-color-box .event-name-label {

  white-space:  break-spaces !important;

}

is not working (even I changed the "toolkit.legacyUserProfileCustomizations.stylesheets" to "true").

Can you help me with that issue?
