Thunderbird Support Forum

I can't receive emails at any address from those in Thunderbird. I have several addresses, some in Gmail but not all. And in each of them I get this message: The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials. I am using version 115.5.2

I just recently downloaded Thunderbird after using Mac Mail for years. Mail suddenly refused to display messages and no one on the Apple forum could figure out why. So I was advised to download Thunderbird. So far, I'm not a fan. Here are my issues: 1. Unread messages in the Inbox are in bold. But the bold is so close to the normal font that I can't tell them apart. Is there another, better way to mark unread messages? A tick/check mark? A coloured background? 2. Messages are automatically organised into conversations. But when the latest message comes in, the inbox message doesn't go bold. So there is no way of knowing where to find it. I have to go through all messages that have a conversation (more than one message in the inbox) and find one where the latest message is in bold at the bottom. It's a royal pain. I see the number next to the account on the left, but nothing is in bold on the right. Grrr. 3. The conversations are the wrong way up. I want the most recent message at the top, not the bottom. I would actually prefer not to have them in conversations at all, just the most recent message, but I realise that is probably asking too much. 4. There is no number next to the Thunderbird icon on my desktop when I get a message. I used to appreciate this in Mail. It told me if it was worth going to my inbox. With Thunderbird I have to open the program to find out. Ok, that's enough for now. I'd better not get started on the shortcomings of the search function, or how to bring the unread messages to the top of the inbox list... There are just too many issues to address is one posting. Thanks for any help you can give.

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

The last couple of days emails from one particular adress (mail send from or generated in our membershipsystem) have started to disapear from my inbox.

I'm not aware that any updates have been done since when it worked.

The mail shows in the inbox for maybe 5-10 sec and then puff without me doing anything or if I click away from inbox and back it's gone

I have checked my spam, the trash and my filters and I have done a search. Even ended up deleting my filters, to be sure.

I have made sure the email adress is not on any spam list. I even tried to make a filter where it would copy the mail to another folder to see if it would stay there (it didn't get copied).

The mail is also gone when I check directly on the webmail with my mail provider.

On my thunderbird I have three different email accounts from the same email provider. I tried sending the same mail to two of my accounts at the same time form this particular emailadress (I can acces the membershipsystem and send / generate mails from there). The mail was recieved and stayed on one account but not the other.

I'm running out of things to try - please help me.

Ubuntu 18.04.6 LTS and Thunderbird 102.11.0 (64bit) Archives in TB show 2021 and 2024 only but both are empty Archives.sbd contains 4 files: 1) 2021 (empty), 2) 2021.msf, 3) 2024 (apparently all missing emails are dumped here, but not in clear readable format) and 4) 2024.msf I did not intentionally archive the files; could be by accident clicking "A" but unlikely that I accidentally also had selected app. 3,000 emails. App. 60 mails were left (i.e. not archived) in inbox Tried to archive one file afterwards from inbox. OK, went correct to 2024 in the same folder as all the others. However, this mail was visible in Archives, 2024 in TB. I moved it back to inbox without any problem but strangely it still also is in Archives.sbd, 2024! HOW CAN I GET THE EMAILS (app. 3,000) FROM Archives.sbd, 2024 BACK TO TB?

I've been plagued with incoming messages that use a foreground/background color combination too dark to read without forwarding the message and then applying white to the swept text. The uploaded image shows the progression of reading the message, sweeping the text in the message (still uncomfortably dark with low contrast), forwarding the message (still unreadable), then select the text and apply white as the text color. I've googled this problem to no avail as most hits are for color contrast in the inbox format for color.

One solution is to switch themes from "dark" or "system theme - auto" to "light" then Thunderbird switches to black text on a white background and the incoming message is readable.

Is there a setting I'm missing to automatically solve this without having to swap theme's to read a message then swap back to preferred dark mode?

I have been working fine with Thunderbird, but today it won't start up. It asks my master password, but then it doesn't show the screen with my email accounts / emails.. In task manager I have two lines with Thunderbird, but no activity. I tried to re install (without uninstall as I don't want to lose my emails), but that didn't change anything. Not sure what I can do.

I am getting the Mozilla Thunderbird Email wants to access your Google Account all the time while using TBM, I have removed the gmail account and the pop up does not show, so I know it is for the email account just removed. I re-add the email address and enter the email address and password and let it find the config itself. Click Done, and get the Mozilla Thunderbird Email wants to access your Google Account again, then click Allow and get the Authentication failure while connecting to server imap.gmail.com. message in the bottom left of my desktop. How can i get gmail to work again please.

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

When composing a new message (in other words, not replying to a message) I want them to always show the default email address, the one corresponding to the top account. The field "Outgoing Server (SMTP)" shows (Default), and ordinarily it works fine, but occasionally it will use one of the other email addresses. In reading your responses to other questions I've seen that the default address is only used when TB can't figure out which address to use. Is there some way I can tell TB to ALWAYS use the default address when composing a new message?

I wish to try K-9 Mail on my Android - eventually I want Thunderbird. When I start K-9 it offers me "IMPORT SETTINGS" and then says CHOOSE FILE. What file(s) do I need to bring over from my Thunderbird profile to get 1. the address book(s) and 2. the email account data?

I am going to be setting up a new email address provided by a new ISP, and would like to migrate the email from the soon to be shutdown current email account to the new one. Is it as simple as changing the account settings of the current account to the new one or is it more involved than that? If so, can I migrate the existing email to the new account without any ties to the old email account remaining? Thanks in advance for any assistance.

I installed Thunderbird on Windows 11 and moved my old profile over from my old computer.

Everything is fine except that HTTP: links will not open. It recognizes them because the cursor changes when I hover over them, but clicking on the link results in nothing happening.

Chrome is my default browser.

I have followed all the suggestions here: https://support.mozilla.org/en-US/kb/hyperlinks-in-messages-not-working including checking that a default browser is set, using the config editor to check that network.protocol-handler.external-default preferences are set to true, and trying it in Troubleshoot mode.

Incidentally, mailto: links work just fine.

I'm currently using Thunderbird 115.6.0 (64 Bit) in Win 10. There are a couple of old email accounts that I need to delete as they no longer exist, but although I can delete them using the Account Actions method under tools, they reappear next time I open Thunderbird.

I have looked through the older posts on this topic, but nothing there has helped. Any thoughts?

Many thanks,

Kelvin

"Enter Password" box no longer comes up when I start up Thunderbird. One account has password saved but the other doesn't so I cannot access emails on this account now as they won't download without either a saved password or (as I usually do) entering a password. This affects my husband also so not just something on my account. This happened around the 20th December. I've searched through Thunderbird settings but I can't find any way of adding a password directly into Password Manager - only edit or delete. So I can't fix the problem we now both have with accessing new emails. So - any suggestions please or is there a fix coming?, kind regards

Hi! the last version of thunderbird (115.4.1 on Windows 10) don't remember the last mail selected when I change the folder. I try to explain better, for example if I go to the inbox and select one mail (for example the last mail received), if I go to another folder and then go back to the inbox folder the view is another one and I have to scroll down to find again the last mail received. I 've the same problem on my office computer so I think it's a problem common... This issue is come since I installed the Supernova versions.... Thanks!

ps this problem seems to be present only in the inbox folder if the last message received is in the bottom (mail from the oldest to the newest) If I change the sort with the colum date to have the last message in the top (mail from the newest to the oldest), the problem disappear

Since my latest Linuxmint update (Linux Mint 21.2 Victoria base: Ubuntu 22.04 jammy), when I right click on an email address NOTHING happens. It ALL versions before 115.5.0 when I right clicked on an email address I had options like: I could copy email address OR even start to new email with that email address as the recipient + Others. Is this deliberate in 115.5.0? or is there a way I can get it back?

thanks Sam

I'm trying to install Thunderbird to access Spectrum webmail with my computer running Windows 11. I have this on 3 other computers running Windows 10 with no problem. Things I've tried: Using both webmail.spectrum.net and mail.twc.com for both incoming and outgoing servers (both work on my other computers). Setting up for both IMAP and POP3.
