Since Thunderbird was upgraded to 115.10.1 (64-bit), it now fails to send SMTP messages with the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) ***.mail.pairserver.com was lost in the middle of the transaction. Try again.

This affects all six(6) accounts in Thunderbird, all of them can receive and edit e-mail messages; however, all of them fail to send e-mail messages.

Prior versions of Thunderbird have worked with this configuration for many years.

Other e-mail clients such as Evolution do not have this issue and I have confirmed with my provider that Thunderbird is no longer sending e-mails.

Any thoughts on how to roll back Thunderbird until this issue is resolved?

Once again Firefox has decided to take over and change all my settings! I had finally managed to prevent it updating, as each and every time I had to reinstall all my setting and extentions from scratch. Today, it decided to clear all my preferences and change itself to its own default settings. OK, so I can change my profile option, except all three are using the same defaults: I appear to have lost all my settings and extensions entirely. OK, I'll copy from my backup, but once again the three backup profiles are being overwritten with the defaults. Even my third backup of last March overwrites to the defaults! How and why is Firefox managing to keep overwriting my defaults to its own preferred settings? How do I stop it doing this and regain my own preferences?

I also tried Sync and now I am getting bookmarks from over five years ago! And once again my settings are changing to the defaults. Surely a Sync should overwrite with the current bookmarks and settings not just keep adding more and more. I am now in a right mess again. Back to losing everything with updates. I am a great believer in the 'if it ain't broke don't fix it' mentality, but Firefox has broken itself and is refusing to allow me to change to how it used to be! How do I restore my own preferences and prevent Firefox from changing them to what it wants.

Hello,

I have a strange issue that i didnt find a solution for online. I have made a few new folder and message filters for them. I dont get number notification in taskbar for mails that go in the new folder while the notifications for mails that go in the inbox work just fine.

this interface uses pop3

When emails are pulled, I can see that it pulls, let's say, 50 messages, the notification shows 25 new messages but the inbox only shows 10. I have looked everywhere for the "missing messages" but don't see them anywhere. I have also had some people tell me that they sent an email response (so they were not entering the email address) and I don't see it.

What could cause these differences?

My Firefox is the most recent version 126. I am having trouble with pop-ups being blocked. I have added the website to the pop-up exception list. When I go to the site, it shows me the little icon showing I have added exceptions for this site. However; the pop-up still gets blocked.

The site is: https://www.foxit.com/ I try clicking the Log In drop down then Foxit Account. Before this would pop-up the log in screen for the site but since version 125, it does not. I just updated to version 126 to see if that resolved it before creating this post but it didn't. Thus I am here trying to get help.

Hi I cannot get this site to load up on my phone it will load up but not on my laptop . am I missing a setting

Hi, I am on a HP laptop using T-Bird 115.11.0 (32-bit). I am trying to add a new contact to the address book. There is a problem or I am doing something wrong.

The right side of the screen offers me to enter details of the New Contact. However, it only allows room for 1st name, 2nd name and Display Name. Once entered I cannot scroll the screen to enter more details or to save what has been entered or anything - except to close address book or cancel which button only partially appears. By clicking around the white parts of the screen I can get Nickname to appear (see screen dump) and I fill it in and then nothing. I am effectively stuck. Looks like there is some window sizing problem here which is preventing the user from seeing how to proceed with completing this form.

For some reason, recent updates caused my Firefox address bar to misbehave.

I have already murdered the unwanted search engine suggestions which the standard settings failed to kill - I just kept turning things off in about:settings until the garbage feature died.

However, I am still unable to address the most annoying bug.

When I start typing in address bar, the pop-up box with suggestions, rather than attach itself to the bottom of the address bar, goes to some imagined, predefined anchor point which is off screen, somewhere outside the confines of the window. As a result, I see some suggestions, but I no longer see what the hell I'm even typing. I am attaching a screenshot. This is super annoying, as I am literally forced to either use bookmarks, or type out urls in notepad then paste them over.

Anyone can help?

A few months ago

If I deleted an email or moved it to another folder - on my apple app for any of the accounts that I also have on thunderbird

The changes would sync seamlessly - a few seconds after I deleted or moved an email on my apple iPhone mail app - on my laptop - thunderbird would show the same changes.

The same worked the other way if I deleted or moved an email on thunderbird on my laptop - my iPhone would show the changes in seconds.

However now if I do the same on my iPhone The changes do not show up at all.

BUT if I do the changes on my laptop - they will show on my iPhone. It just doesn’t work if I do the changes on my iPhone.

Is there a reason for this?

I recently moved to using Thunderbird for my emails on an iMac running MacOS High Sierra. I am baffled by the number of email erasure/disposal options I was suddenly presented with, namely: 1. A "Trash" folder, with trash bin icon; 2. A "Junk" folder with a flame icon; 3. A "Junk" folder with no icon; 4. A "Junk E-mail" folder with no icon. Confusingly, some of these folders are not provided with an "Empty deleted/junk" option! Can I completely delete folders 3 and 4 (the one without an icon)? And finally, how can I set things up so that the deleted and junk folders are automatically emptied at set intervals?

Many thanks in advance for any assistance!

I keep receiving this page - https://accounts.google.com/_/bscframe - when I try to add a Gmail account to my Thunderbird Beta 127.0b1 (64-bit)

How can I add a Gmail account to my Thunderbird which already has some email accounts (Gmail and others)?

Thanks for any help you can offer.

Within 24 hours this weekend I was notified by my anti virus application (Avast) that they are no longer supporting Firefox browser (to concentrate on Outlook and Chrome), and a political news website that I frequent (Meidas) blocked me with a "captcha" type puzzle. The website said my browser was mimicking robot or bot use. I was presented with a puzzle requiring me to slide a tab rightward. It repeatedly told me I had slid the tab incorrectly. I believe all of this happened after an update of Firefox about the middle of last week.

Good day,Thunderbird keeps deleting messages older than 1 month. I have checked the settings of my account as well as thunderbird and both is on do not delete messages.

We use this account for business and would like to search emails older than a month for references.

I have two monitors; I keep my taskbar on the right monitor and run Firefox on the left monitor. For some reason, whenever Firefox gets minimized, the window moves to whichever monitor the taskbar is on (I've done some testing to confirm it is specifically the monitor the task bar is on). Because I also run a program called max.to to separate my right monitor into different sections, this action of minimizing to, and restoring to, the wrong monitor is also resizing my Firefox window.

Is there any way, any option I've overlooked, that would get Firefox to minimize and restore to whichever monitor is is actually running on?

I've attached an image that shows, as best I can get it, the window moving over to the task bar monitor when minimizing.

I have two Google (yes, Google, not gmail) accounts. When setting up my gmail in Thunderbird, I was prompted to enter the Google account. I have entered the wrong one. Consequently, I cannot access my gmail: "Unable to log in at server. Probably wrong configuration, username or password."

I have tried all ways I have found in this forum to get rid of it again, such as editing the prefs file, but to no avail.

How can I remove the Google account from the Thunderbird settings to be able to insert the new one?

Thanks for your help in advance, Matt
