I used to be able to clear all data with no problem, but now it's holding to Gmail login data (I think that's the problem, anyway). I clear all data after each browsing session and have been doing so for a long time, but it's not working anymore. But it is working on my husband's laptop and we're on the same version of Windows (11) and have the same settings. Can someone please assist in figuring out what's happening behind the scenes? Thank you!

Lightning Strikes again.

As soon as TB upgraded to 143 I had the following problems:

1. Half my folders disappeared. In this day and age, where emails are "official documents" to prove communications.... 2. I could not delete any email, folder. 3. I could not create a folder.

So, I deleted that installation and reinstalled TB.

Same issues. NO CHANGE with a clean install.

Hi,

I have 2 machines (Win10 and Win11) with FF 140.3.1esr (32-bit) installed which demonstrates the same failure when I enter one site's url:

PR_CONNECT_RESET_ERROR

Chrome at the same machines goes at this url w/o any failures. Any ideas what to change on "about:config" in FF to allow it opening this url w/o such error?

I have two Gmail email addresses. One is used for important messages. As of last Thursday I am not receiving some emails sent to this account. I asked sender to use secondary email and they come through. I’m very concerned that I’m missing important messages and need to get this corrected quickly. Please help if you can. If I need to delete Thunderbird I will but hope not.

In Outlook, it would say that "I replied to this message on xxx" in the header (not sure if that is what it is called, but near the top). I found it helpful to at least see if I have already replied to a message received. Is that feature available in TB?

Hello all!

I use Thunderbird as a local archive for my email. I have two accounts in the application: my home email via my ISP (POP) which I predominately use and my gmail (IMAP) which I don't generally use. There are years of messages in folders and sub-folder under the POP account, but nothing under the IMAP.

I’m up to date with Thunderbird at v140.1.0esr (aarch64) on my iMac with Sequoia 15.8.

On 07/22/2025 I went to download some messages via my ISP POP account and saw that a whole bunch of my email folders no longer had any subfolders and were empty of any messages. Some were also duplicated. Please see the attached image.

I haven’t changed any settings in years, and I do not have any add-ins. One of the nice things about Thunderbird has been its solidity and simplicity.

After every session, I would empty my trash and compact.

Suddenly my email seems to be gone along with sub-folders while top level folders are duplicated.

Wondering if anyone has any suggestions on how to troubleshoot this? Since I don't do anything fancy with the application and with the suddenness of this issue, I can't image I'm the only person having it? I’m quite concerned I may lose many years’ worth of messages.

Thanks much in advance! CPRoot

Hi there,

For some reason, all my text has been showing up as bold on my Firefox web browser. However, the same sites do not appear as bold on the mobile Firefox app or in a private Firefox web browser.

While I thought it applied to many different fonts, it seems to specifically target Roboto. This is especially troublesome because my photography website has all body text as Roboto:

https://www.koby.photography

This was not always the case, but one day everything began appearing bold several weeks ago. Text that is italicized seems to stay in italics and not bold.

I greatly appreciate your help and support. Thank you in advance

Since the last update the following error occurs: If I delete individual entries in the browser history, they don't stay deleted, hey are back after a while.

Is this a bug?

auto filling of password in Android not working properly I mean its not promoting automatically fill the saved password. It also not fill in Android desktop mode. But in pc it's working fine with same login id.

This pop message appeared about 4 hours ago. I still cannot recieved email. Do you know why and how long it before the system is working again.

Thunderbird Alert from account peter@pfirving.com: Account is temporarily unavailable.

I have used Thunderbird to manage my google calendar on PC, windows 11, for years. It seems now that when I add an event, hit save and close, it is not saved. All the events show. I can add events on my phone, and they show up in the calendar on Thunderbird, instantly. I just can no longer add events. I can try, but when I save, they do not appear in the Thunderbird calendar, or in Google. I did just recently change my password in Google, and had to re-authenticate Thunderbird, I suspect that's the instigator of the issue. I just feel I'm missing something. One note-if I click on "add account", there is no option for calendar anymore. Maybe this is gone.

I have previous ask questions on how to transfer profiles, local folders, sent messages, and all address from my old Windows 10 PC to a new Windows 11 PC. "David" provided a very help way to transfer the profiles between machines which helped immensely. However, I still do not seem to have the address book file(s).

Here is where I am and what I would like to be able to do.

When I first installed Thunderbird on the new PC, I set it up as an IMAP account with comcast.net. The contacts in the address book were showing. When I copied my Thunderbird profile from the old PC to get my Local Folders, the address book was gone. I repeated the install process and copying process to make sure I was not making an error. The results were the same each time.

What I would like to do is to find and directly copy the address file(s) from the old PC to the new. Is this possible and where are they located?

Thank you in advance to the time and patience to answer my question.

Firefox declare to be aware of privacy but as soon as I use Firefox to go on the internet, I immediately get connections from these 2 addresses : 34.107.243.93 34.107.221.82 in addition to the address of the site I connect to.

And sometimes, I receive so many connection attempts on ports that are not implied in the connection I have established with the initial site (conntrack) that I am obliged to disconnect the network.

This does not happen with other browsers like Konqueror, Falcon, etc. I suffered an attack in this way in the past with heavy consequences. Is there a way to configure Firefox in order to suppress it ?

I've used Thunderbird with the Owl add-on for Exchange/Outlook accounts for several years. Recently I've found when I open Thunderbird on my laptop, a tab opens for each account, apparently showing the Outlook web page for each account. This is great, but on the same version of Thunderbird (140.3.1esr) on my desktop, that doesn't happen. I can't see how to open these tabs there, or even how to reopen one of these tabs on my laptop, except from Go->Recently Closed Tabs. Am I missing something? What controls this behaviour?
