Thunderbird Support Forum

For the past several years I have been dealing with Thunderbird occasionally freezing on me, with the window losing focus and the titlebar saying (Not Responding).

It appears to happen when TB is downloading email. If the emails are large (as some are) TB stops everything to deal with it. I have looked for where to change any settings to allow for process threading, since that was the promise of Windows waaaaay back in 1990. Not so, apparently with TB. Even if I'm in a separate window composing an email, it freezes. I wrote about this back in 2018...

https://support.mozilla.org/en-US/questions/1233121

I noticed that this only happens when downloading emails from one particular account, which I use for receiving project code error debug reports. The emails are typically around 150k or slightly less. Not so huge that it should take so long to pull down, but the debug info is in many, many nested tables and divs. Is it trying to render them, even though I don't have them open?

In any case, I set that account to no longer collect. Yet, every once in a while, it still collects. Do I need to remove the account from TB altogether? I would like to be able to have this account checked every 15 minutes like my other five email accounts, which don't cause me any heartache, but it's driving me mad, especially when a throng of those emails come in, like 50 at a time, and I am effectively prevented from doing anything in TB for up to five minutes. I suppose I could craft the emails to be smaller (it's my own code that is sending the debug reports) but the info in there is there on purpose.

Is there a setting I can change somewhere to break off the processing for the main window and the compose windows?

Hi - My company turned on some additional security settings for connecting to M365. Thunderbird Windows successfully provides the needed Entra ID, that is required in our M365 environment now for access by registered devices. The state of the device, as being registered in Entra ID, doesn't seem to be able to be passed via Mac Thunderbird but does for Windows Thunderbird?

This is the error - the fact that it shows the Device as unregistered is the key item - Thunderbird needs to be able to send the :

Is this something that can be addressed? I am really disrupted by not being able to manage my email through Thunderbird...

Blocking remote content by default is a very positive security feature. But needing to add each and every email address individually is NOT optimum and wastes a lot of time. We really need a method to globally allow remote content from specified domains. For instance, it would be handy to allow remote content from any/all email from IBM, but I certainly don't want this for gmail.com addresses. This seems like a very simple improvement to code.

I'm looking for a message filter function that will wait a specified period of time before performing what the rest of the filter does whatever it is tasked to do. For instance, I want to have an incoming message sit in the inbox until it moves to a local folder some time later. This would allow me to see it from a device that can't see local folders (like a mobile phone). I can't find anything in extensions. Any thoughts?

HI

Outh2 Saved Password entries is being removed automatically after few months in password manager. It is asking again to Re-Authenticate. After authentication, It is getting removed again after few months. Please help.

Hi Everyone. I'm sure that Thunderbird used to have the option to show conversations (received AND sent messages) in folders especially useful in the Inbox. However I can;t see a way to enable that in the current version. I know I can go to conversation view in the context memory but it seems crazy that is an option by context but can;t be set as a default for 'normal' viewing in folders - all I can set is to see half the conversation with the trail of received messages but not my replies intermixed with them so I see the whole conversation. Am I missing a setting somewhre? Thanks fo any help.

Currently notifications has the same app_id and the same window properties as the main one. It makes it impossible to assign any rules from my window manager to render notifications differently. For example, I'm using Sway and Arch, and I would love to show notification on the current desktop, but assign main thunderbird window to a particular desktop

I use comcast.net for my mail email, Gmail for my second, and I want to add both. THat is another topic I want addressed if it is possible to have tow simultaneous email accounts with the same Thunderbird email program, so I can switch back and forth when I need to.

My main concern is that when I go to add comcast email, it automatically forces me to sign in to the Xfinity website. I also have two-factor authentication where I click on the Xfinity app on my phone giving me permission to sign in.

It tries twice even after I click on the Xfinity app to give permission, but it fails. So, Thunderbird is pointless without me being able to successfully add my email client. What say you? And do not in any way point the finger at me, my devices, my phone or Comcast. Please get the solution, without being a narcissist, to fix my problem. I have all I can stand of this in the past. I appreciate it kindly, and thank you.

And I am not allowed to use any other form to sign in, even a text message because I use the Xfinity app. I am unable to change that, so get this fixed for me. I used Microsoft Outlook in the past with no issues with Xfinity and Gmail. See image screenshot on this post

I have two email accounts on my website that is hosted by Hostpapa. Years ago I successfully set up email for both accounts in Thunderbird. Recently (probably after an upgrade) one of the accounts stopped working and I get a timed out message when fetching email messages. After checking the server settings and password were correct the problem was not fixed, so I deleted the account and tried to re-add it in Thunderbird. The incoming and outgoing server settings are correct as is the password. I know the password is correct because I can successfully login to the account using webmail. I received the following error message on the "Setup your Existing Email Address" page. The message appears above the "Checking Password" button.

"Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsiMsgAccountManager.createIncomingServer]

The password on the account is 16 characters long and contains the following special characters: "!#"

I am using Thunderbird version 115.11.1 (64-bit) - on the esr channel

Can anyone help?

I have just completely reinstalled Thunderbird v115.11.1 after uninstalling the previous installation. There are two problems, possibly linked to a faulty or missing setting.

Remote images will not display, even after specifically enabling remote images for each email, or after turning on "display remote content" as a default. Also it claims there is a potential security threat with Thunderbird's own web addresses: "live.thunderbird.net." and "addons.thunderbird.net.".

I have attached screen-shots of the error messages, and of a thunderbird email that fails to display its images.

Recently the email display has been changed and not by me. At present I cannot receive emails as previously. Also I wish to revert to the previous display of my emails if possible. I can access email via the email.telstra,com site but I wish to stay with Thunderbird. I also do not get emails to my mobile as before

Good afternoon I have 2 accounts in Thunderbird - a gmail and a Yahoo. Both were running great from the time I set up Thunderbird about 2 weeks ago until yesterday when the gmail account stopped sending and receiving. The Yahoo account is still fine. I have not received a message in Thunderbird in my gmail account since, although I have logged in on the web and confirmed that there are incoming messages in my account.

When I attempt to send a message from the gmail account I receive an error message - "Add Security Exception". If I click "View" nothing happens. If I click "Get Certificate" the section "Unknown Identity" changes to "No Information Available". However, when I cancelled the message I noticed a new error message appeared - "Send Error Message" and when I returned to the main Thunderbird screen I noticed a new tab appeared "Certificate for smtp.gmail.com".

As you can imagine, I seem to be getting nowhere with this and as I am only an intermediate user with computers I don't know where to go next. Subsequently, I sincerely hope that someone out there is able to help me. Any assistance would be very much appreciated.

The following are my Thunderbird settings for the gmail account :- Incoming Server Server type : IMAP Mail Server Server name : imap.gmail.com Port : 993 User name : [myname]@gmail.com Connection security : SSL/TLS Authentication method : OAuth2

Outgoing server Description : Google Mail Server name : smtp.gmail.com Port : 465 Connection security : SSL/TLS Authentication method : OAuth2 User name : [myname]@gmail.com

A copy of the error messages as well as the Certificate are attached.

I only wish to sort email only from known vs. unknown domain sources into different folders. Is there a method to filter messages from @AnyDomainName where the domain is NOT found in entries of my address book? Specifically, this method would ignore the Sender Name and only scrutinize the domain.

I often copy a link from web, then open Thunderbird to send that link. Thunderbird will not accept the 'paste' until I have gone back to the source, copied again and returned to the (now opened) Thunderbird. Annoying and inefficient! How can I get Thunderbird to allow 'paste' from my clipboard on the first try?

In Outlook you can forward an appointment that is not created by yourself to someone else. In Thunderbird this option seems not available, or is it? Adding attendees to an event that you did not create yourself does not work.
