win11 :Thunderbird will not launch, It appears the issue is a Background Process labelled "Thunderbird" which is unresponsive to "end task" in Task Manager. Will launch after reboot.

I have no clue as to how Tbird into this state, but it has happened more than once

My email is [redacted] @cox.net, which now redirected to a Yahoo site. Was working unbtil a month ago. Now it says downloading emails on startup but I cannot get or see anything after 8/20/2026......

I disconnected a Google Workspace account - Calendar and mail - from a former workplace. As far as I can tell, it's been deleted from Thunderbird.

However, I'll still get dialog boxes and an occasional browser popup asking me to reauthorise it.

How do I get rid of it once and for all?

Since our clocks/time went back one hour last weekend, Thunderbird for Mac is displaying the incorrect time. It displays the time as 1 hour ahead, effectively hasn't accepted the time change. The system time is correct, and Thunderbird is set to read system time. I have also tried changing it to "set manually" to our location, it makes no difference. Any assistance greatly appreciated.

I am using TB as my email client. I use it to manage my email from Greenby who are an email and web hosting service operated by Enix Ltd. The ISP Plusnet has migrated customer's email from their servers to Greenby's as they no longer provide an email service. I am in the process of leaving Greenby (A look at TrustPilot reviews will tell you why.) At some point I will be closing my Greenby account as it attracts large amounts of spam and scam emails, which it is time consuming, difficult or impossible to block.

I want to archive my email to my hard drive and I have read the guidance on how to do this using TB. I am quite happy to keep the TB software on my PC.

Will I need to keep TB software to read my archived email? Does TB function if it not acting as a client from a third party server?

Any thoughts or advice would be appreciated.

I recently installed Thunderbird on both of my Windows 10 PCs.

I have two email accounts:

axxxa1@shaw.ca

and

axxxa2@shaw.ca

The first account worked perfectly upon completing the Thunderbird set up.

The second account does not work and I have spent hours playing with various Configuration options.

It's very strange that BOTH of these email address successfully pass the "Connection Security" test.

I'm out of ideas.

Incidentally, I still have Eudora 7 on my PC and BOTH emails are working fine in that application.

Hopefully, you can assist me to resolve this problem.

I'm on Windows 11.

Moving Thunderbird to the system tray was working correctly in previous versions, but since the latest update to Thunderbird 1560.1, clicking X sends Thunderbird to the taskbar instead of the system tray.

Thunderbird is not pinned to the taskbar.

I have also tested the setting with the option disabled, restarted Thunderbird completely, then enabled it again and retested. The behaviour is unchanged.

Hi! I'm hoping you can help me! I use Thunderbird, and have for many years, and I love it. My computer is on its last legs, and I'm trying to save up for a new one, but, yesterday I did something possibly stupid... (yeah, I know, you NEVER get people asking for help who've done stupid things, so this will be unusual... lol). Anyway... I turned my computer on and got a popup saying that my Thunderbird needs an update and it's been a while since I updated, so I hit OK on the update... Well, my arsehole of a computer chose that exact minute to shit itself and die. When I tried restarting it, my Thunderbird no longer works. Now I have a popup with a big red X that says "The installation seems to be corrupt. Please check your hardware and disk setup and/or re-install." Can you help me? I desperately need to check my email and have one I need to send. I don't know what to do. I've also got YEARS worth of emails sitting in the system, so I can't risk losing them, either. Please help. L.

HELP‼

Are there any •SERIOUS• “Thunderbird” savvy computer geeks in 155.0that could help me merge “old” user profile directories from *crashed* computer to a new computer without messing up either one?🙏

i used to do this stuff (with my eyes closed) but I no longer remember if I had breakfast today and they are my wife’s files! 🤬

I have new notebook computer plus the •entire• old computer data on a USB stick.

Enclosed are jpg copies of the current sets of filters failures in my TB email program.

TB Error0 shows the 6 emails that have arrived and are placed in the INBOX. However, each of these has a corresponding filter set up to move them upon arrival to a separate subject email mailbox.

Note: If I highlight the INBOX and then go to Tools > Run Filters On Folder ... all of these INBOX email messages will be correctly filtered and moved to their respective email mailbox, BUT each of them is shown as having been "read" and unless you pay close attention, you may not know where these INBOX emails were sent.

I am also enclosing TB Error1 & 2 that show the last couple of days message filtering errors.

I can find nothing wrong with how each of these filters are set up, yet they seem to consistently fail to operate when new emails arrive.

Note one of them is for incoming emails from ... schiffsovereign.com. I have edited this filter repeatedly, even deleted it and re-input the information. Yet the filter never takes hold and does what it is designed to do. I am enclosing a jpg of that specific filter as TB Error3

I am looking for suggestions on how to fix this problem.

Thank you and best wishes,

Windooze 11. TBird 152.0 installed on June 20th. Now it seems like TBird is not displaying HTML emails properly. They are displayed but not at the beginning. The first line is sometimes just the bottom half of a sentence in the email (if that makes sense). I can't scroll back to the beginning. If I go to outlook and display the same email it displays fine.

Did something change in 152.0 to cause this?

Thanks, Ed Mazurek

First some feedback on your website, the URL is https://support.mozilla.org/en-US/questions/new/thunderbird/form If you are going to present the user with a list to select from, as you do in your selection list, "Which topic best describes your question?" ALWAYS present the user with an OTHER option. Despite you ego, thinking you can cover all the bases that a user will want to send you a message about, YOU CAN'T!!! Make sure ALL selection lists have an Other option on your website.

My version to Thunderbird, 140.9.0esr (64-bit), running under Linux (OpenSuSE 15.6) has developed a problem with the Trash folder. Despite the fact that I am deleting email messages or moving them to the Trash folder, nothing is showing up in the Trash folder, even though the messages do seem to be getting deleted or moved from the source folder. Also the Trash folder is always showing me I have 99 unread messages in it.

I have tried to repair the Trash folder, but no joy. So how do I determine what's bugging my trash folder, and how do I get it to behave itself once again? Thanks in advance for all thoughtful replies and responses!

Marc...

My Inbox folder has suddenly dropped to second last position in the folder list. How can I get it back to the top of the list? Is it possible to move the folders around?

I'm trying to setup Netzero email on Thunderbird. I get the error message, posted in question. Outgoing mail works but can't load inbox messages. I got the following error message when I first started Thunderbird - "The STAT command did not succeed. Error getting message numbers and sizes.Mail server pop.netzero.com responded: POP access disabled"

For about 2 weeks, EVERY time I try to write an email, after typing a few lines or so, the whole window 'grays out' and becomes UN-responsive. I get no error message. Waiting for it to respond doesn't work and I have to close out and re-start Thunderbird. Sometimes Thunderbird will have saved some portion of my email in my 'Drafts' folder, but not reliably, so I have to frequently 'Control + S' - save it to avoid having to re-type the entire message again. Troubleshoot Mode doesn't help, nor does clearing the cache. I've been hoping an update would come up that would solve this, either from Thunderbird or Windows (11), but not so far. Please tell me how I should resolve this - I have used Thunderbird for years (and regularly contribute too) and don't want to have to change to different email client.
