Starting 3 days ago: Cannot SEND email - receiving works fine. Error message: An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The other odd thing is that I get asked for a password before sending which never happened before.

I followed advice given someone in 2022 - I've messed with the account settings (unfortunately) and I've changed the SMTP settings to match what Comcast recommends.

I have 3 comcast accounts; two work fine on my iPad and iPhone - one doesn't

Also I have no problem sending emails using Xfinity/Comcast Mail... but I want to use Thunderbird.

Where do I start looking?

Thanks!!

I'm sure I've made the problem worse by trying to change the setup

Every time when I refresh pages on my CRM Firefox ask me to allow to give access vats556967.megapbx.ru access microphone to your microphone. And If I press allow this popup show again and again again every time when I refresh page It show this popup and I can't work I my CRM. I can't remember My choice that allow, I don't know Why. https://youtu.be/-0r42kwGOcU

please help me I already ask my CRM system developers to help me they check all info and said that problem in Firefox and please send Firefox support question

I check it on another computer and there I get the same problem.

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

This problem started yesterday. Whenever I try to connect to a website, I'm met with an error saying "Secure Connection Failed", each time with a different error code. Dropout.tv gives me PR_END_OF_FILE_ERROR, Netflix gives me SSL_ERROR_RX_RECORD_TOO_LONG, DuckDuckGo gives SSL_ERROR_RX_UNEXPECTED_APPLICATION_DATA. This doesn't happen with any website owned by Google, such as YouTube, Google Docs, etc. I don’t know if there are any others that it manages to connect to, but those are the observations I've made. What can I do?

Hi,

Thunderbird suddenly stopped working today,, can not receive emails or send emails. I can log directly into web client and emails are sitting there have confirmed settings with my hosting company and everything is working their end they have also confirmed the settings are correct in Thunderbird

It has been one year, and you still have not fixed the multiselect functionality that was ruined with your Supernova "update" (which is worse in almost all aspects btw). Can you at least tell us WHEN you plan to release the fix since you locked the comments to block the countless negative ones? Is it so hard for your UX team to understand that removing multiselect functionality is like removing Ctrl+C, and Ctrl+V and set the correct priority???

So I've had Thunderbird for a few years. I've always had my (multiple) email accounts set to both check for new messages at startup, and check for new messages every 2 minutes (I keep it open in the background so I can be alerted ASAP). However since the last 2 updates, I can no longer fetch messages either every x minutes, or manually (Get Messages does nothing), and the only way to get new messages is closing and restarting TB completely, defeating the point of having it open in the background.

I've tried: 1) unchecking both 'Check for new messages at startup' and 'Check for new messages every x minutes' = still can't manually pull in mail with Get Messages (the status bar says it's checking, but nothing gets pulled in unless I restart TB)

2) leaving ONLY 'Check for new messages at startup' OR 'Check for new messages every x minutes' selected = nope

3) starting and restarting both TB and my PC = nope

4) checking my antivirus isn't blocking anything = it isn't

5) checking all my email account server settings/passwords are correct = they are

6) testing out Betterbird with the same accounts and seeing if it's still an issue = this also affects Betterbird

7) checking my email accounts are working in other software like Outlook/webmail = they're fine, I can get email there normally

Any ideas as to how to fix this?

When I launched Thunderbird this morning the right-hand-side panel is completely blank. The left hand side panel shows my folders and if there are any unread emails in them but the right hand side is just completely blank (as per attached image).

Name Thunderbird Version 115.12.1 Build ID 20240618125055

IMAP account on HostGator.

In the last 9 months or so, every once in a while (sometimes several times in a row!) when replying to a message, Thunderbird does not set the \Answered flag on the IMAP server.

I enabled IMAP logging and finally caught this happening. The reply is sent and copied to the Sent folder, as it should, but the original email is never flagged as \Answered.

I can't seem to see a pattern why Thunderbird skips this step, occasionally.

I visted a web site once and left after trying to watch a some movies without any success. Now my firefox are sending notification to my deasktop from this website. But the site is no longer opened in my browser. I tried to to run the antivirus but nothing was found. I checked for any extension and nothing as well. The notification are coming from the firefox itself and I dont know why. And I dont know how to stop it.

Starting a few months ago Tbird suddenly became noticeably slower, and it's only continued/possibly gotten worse, despite several version updates (which I was hoping would fix it). Currently I'm on version is 115.12.1 (64-bit)

I do have several accounts (all pop) and many folders, but nothing different than before the issue began.

I only have 2 add-ons enabled; Remove Duplicate Messages & SmartTemplates. I've of course disabled them and restarted TBird but it didn't help at all.

I've compacted and repaired all folders.

I've created additional folders to reduce the size of larger folders.

The only thing that helped a bit was troubleshoot mode, which definitely made it a bit better going from email to email and folder to folder, and especially with moving emails from one folder to another (which is usually very, very slow and I see it on the bottom saying "moving email 1 of 10 to folder xyz...moving email 2 of 10 to folder xyz...", even if they are simple/small emails). However, sending emails still took over 5 seconds (see screenshot attached), so that might be a separate issue.

In terms of sending emails, whenever I try to send any email it sits on the sending screen for several seconds or more. My internet is fine (2gb fiber, previously 1gb cable), speed tests max out at the 1gb my laptop can handle. Laptop is 2-3 years old high-end Eluktronics, with no other issues.

Given the above, and that troubleshoot mode did seem to help a bit (but straight out turning off add-ons didn't help), what can I try to adjust (while not in troubleshoot mode)?

Thank you very much!

hello tried a few things from help docs on line. nothing working. just keeps happening. tabs will say gah. your tab just crashed. works for a bit but once happens.... have to close whole firefox and open again. just started happening yesterday. I have used firefox for many many years never a problem. Something was not updated right. Please tell me how to fix this once and for all. if not I have to leave using firefox this is driving me crazy. terrible. Latest thing I tried was about:config - sandbox changed 2 items, 1 from true to false other from 6 to 0. as listed in this https://www.youtube.com/watch?v=_SIGynLjrjk

nothing has worked. Please help. thank you.

In seeking a way to reduce the CPU & RAM usage, I read that perhaps turning on the Hardware Acceleration might help. And to do that, you must first de-select the default setting which says FF will use the best settings for my computer. Well, when I opened that section, neither one was checked! So, should I first try the default setting, and if that doesn't help, then try HA? I'd always heard not to use HA, for some reason, but I'm ready for trying anything that might help use less resources, and open webpages more consistently.

Which is the best setting to use, or neither one?

Its driving me crazy. When I select a group of Inbox emails, and delete them, it is taking forever. The window will display a "not responding" message, eventually clear that and then the emails are deleted. But it takes way too long. Windows 11, most recent update. Thunderbird, it just updated. I was on a Win 10 computer, same Thunderbird version and deleting took merely a blink to happen.

Win 10 has both VPN AND AV. Win 11 has neither. Help! Thank you,
