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?

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?

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

Give that I use TB as my desktop client to access my nyu.edu email (provided by google), and that recently I updated my password as periodically requested by nyu admin When I try to access nyu email a pop up screen come up asking to authenticate with imap.gmail.com. I click next and get a 403 Access Forbidden error (Authentication failure while connecting to server imap.gmail.com.)

Solutions I have tried: 1. Clear cookies, history and cache on browsers and TB; 2. Changed default browsers (Ffox, Ch, Edge); 3. Deleted account in TB and created it again using instructions here https://www.nyu.edu/servicelink/KB0016473 4. Accessed my nyu email on browser to check user name and password. It works. I can access the email.

Nothing seems to work. Still get 403 error. As a result I am unable to authenticate and hence use the email account in TB.

Using Thunderbird on Linux I cannot delete any local folders, when I try to delete them I get more copies of the folders on reopening Thunderbird, after the system says it is "not responding" and I close it down. I have tried several times and now have multiple copies of the local folders I've tried to delete.

Concurrent with updating to Firefox 126.0, when typing into the address bar, the list of suggested sites covers-up the address bar. In fact, the top of the list is off the screen. I don't see any other posts relative to this, am I the only one with this problem... and how do I fix it?

I just updated to the latest version of Windows 10, and now when using Firefox (126.0), the url dropdown menu rather than dropping down now "floats" over the browser window with the top cut off. The top url is still there, and I can navigate to it using the arrow keys, but it doesn't show. This is new as of this morning, when Windows updated. No issue in other browsers.

I received a message with the remark "This message contains an invitation to an event." What follows is several screens of metadata (that's what I think it's called), followed by the original note from the sender. Is there a way for me to suppress all this metadata? When I forward the message to a friend who has an iPad, it shows up without the metadata. I'd like that to be the situation when I use Thunderbird.

I've attached a screen shot of a portion of what I've called "metadata". I didn't include the very top of this metadata because it contains personal data.

Whenever I try to write anything into the address bar the suggestions cover it completely and I can't see what I am writing, see Picutre1!

However when I launch the browser in troubleshoot mode from the help menu, everything works fine, see Picture2.

The only addon I have installed is Youtube adBlock. There are two plugins running, a codec by sisco systems and a decrypt module by google.

Could somebody help me with this problem?

Hi, As the title suggests, I am unable to delete emails from my work Microsoft account.

On attempting to delete an email, the following message is displayed:

"The current operation on "Inbox" did not succeed. The mail server for account [email] responded: [TRYCREATE] The destination mailbox could not be found."

Checking the account settings, it seems Thunderbird cannot see the "Deleted Items" folder (it only shows Inbox and Drafts). I have attached images to show what I mean, comparing with a personal Microsoft/Outlook account where it sends deleted email to the correct place.

Using the latest Thunderbird version that is available on the Microsoft Store version on Windows 11. (115.9.0) I have tried removing and re-adding the account yet the problem persists. Any troubleshooting ideas welcome!

Hi After the latest update, the address bar dissapears everytime I click on it to type in an address. It gets hidden behind previous addresses I visited. Completely unusable. I have no idea why it is so bad and how to fix, please help. Thanks

Hello, while using Waterfox, recently, while on Facebook, the time a post was made on any given page stopped being shown except for the most recent - newest - one. Per the attached screenshots, the newest post shows that it was put up 26 mins before I got the screenshot, the post prior to that one does not show how long it's been since it was made. This is only in Waterfox. Not a problem with Firefox, Chrome or Edge. Waterfox is my browser of choice for all social media, so this is particularly problematic. Thanks for any help in resolving this.

How can I have the original mails deleted from original Gmail inbox when deleting them from unified inbox.

I am reading my mails in a unified inbox - and deleted some read and unwanted ones. Now I am looking at my Gmail via my iphone's mail app - and none of those emails have been deleted... How do I get those deletions to sync back to my Gmail account?

Thank a lot!

I'm trying to use the built-in PDF Editor features after finding out about it but every PDF file I open with Firefox has the options grayed out (as shown in the screenshot). What should I do to re-enable the features?

When I'm in full screen mode, The Apple, "Firefox" "File" "Edit" "View" "History" "Bookmarks" "Tools" etc menu bar shows up at the top and won't disappear. On my iMac Pro, it doesn't show up. i.e. Off.

I can't figure out what is the setting to make sure it does not appear. I went digging everywhere and can't figure it out. If you could tell me what config, etc I'm missing I'd appreciate it.

Screen shot attached to show which menu bar I mean.

My firefox is up to date: 126.0 (64-bit)

I'm unable to send any emails from account on Thunderbird. This just started this week. All send attempts generate this Send Message Error:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Please turn on SMTP Authentication in your mail client. syn-076-088-235-065.res.spectrum.com ([192.168.1.25]) [76.88.235.65]:51343 is not permitted to relay through this server without authentication.. Please check the message recipient

This error for every recipient I typically correspond with. I have my same email account loaded into Outlook on another pc and I can send emails to all recipients without error from Outlook.

Help please.

This randomly happened over the past few months but last couple days it's bad. The Google Sheets cells I have open on Firefox turn black. You can scroll and they will come back but just briefly and back to black. Very annoying as these are shared sheets for my business with other employees. It's not happening in Vivaldi Browser or Edge. I hate Chrome so not even trying it there but guessing it's fine. Seems to just be Firefox all of a sudden. See pic. Help please as I have no clue what's causing this.
