Thunderbird 커뮤니티 포럼

Every time I start Thunderbird it takes several minutes and sometimes doesn't start up. Once it does open up, emails do update new ones but if I go to account settings and select anything it hangs up. If I click on it, grays out and gets a message Thunderbird not responding. I have to open task manager to stop the program. Why aren't the emails on my email server get deleted/ moved updated when using Thunderbird? It seems like the only thing that happens only gets changed on the device I made changes to only. (computer, or phone or laptop)

Copiolet tried to hep me with many different ways. I am locked out of Thunderbird they said I could be frozen and tried to unfreeze it but that did not work Nothing is showing I have thunderbird in the downloads

Home Mozilla Thunderbird (Not Responding) is all I see on the screen.

I have rebooted, reinstalled and still cannot get Thunderbird to start. I have not touched the C:/Users/.../AppData/Roaming/Thunderbird data (where I assume the problem is).

I have just re-started my problem when this system crashes again. For 3 weeks I have sent reports of sites being crashed. The has not been any changes. It happens when on web site and also when using E-mail. HELP!

Topic: My ignorance! Working side by side with my bank account 1/2 size, and 2 columns of my inbox screen 1/2 size worked great! A job well done! Re-sizing TB screen back to normal size caused a large blank screen, headed "Inbox", with only a couple of blank columns, no folders, no Sent, no Trash, and it is unresponsive. I went out and back in and it is the same. I didn't do anything unusual. This is a fairly routine action. Please can you help?

After I open my Thunderbird email and use it for 15 to 20 minutes it freezes. I need to close it and I get a message Thunderbird is not responding. I then need to close the program using Microsoft to close the program.

My machine Intel i3 6100, 16g of ddr4, windows 10. 250 gb ssd +1 tb mech hard drive

Over the last week or so, I call up Thunderbird then when I click on anything, it just comes back "Not responding" Any ideas?

Thanks in advance Tony Sneath

I have a Dell Desktop with 64GB Memory, Windows 11, Intel Core i7-7700 @ 3.60 GHz, 1TB ssd, and two additional drives. On a new installation of Thunderbird 152.0, I get "System Integration" (Not Responding)" window. The only option is to exit. What can I check to correct this. I have uninstalled and deleted the install file multiple times with the same result. Thank you.

multiple copies of emails, usually old ones, cannot delete them, also cannot open new emails, often thunderbird freezes, message comes up that thunderbird not responding

I posted this earlier and the bot named David is trying to take over with ideas that don’t work. How do we stop it? I also posted from my own email and it tried to stop me.

This is Ellen. I tried restarting Robert's ( my late husband) computer after it crashed and I got the message about Thunderbird's inbox folder not being able to be opened because it is in use by some other operation. It is an old Mac Mini running 10.13 and it says TB is 115.18.0. I don't update it because I don't think his OS can handle anything newer. I just looked and my Mini with an M1 chip (4 y/o?) is running 140. something.

How do I get it to quit whatever it is hung up on? His email is coming in ok on my iPhone.

Robert was a sculptor who made large kinetic works and a lot of his work is still on this computer.

Please help me get out of this mess. I think it has happened before.

Thunderbird keeps locking up. I have twice uninstalled and reinstalled, yet Thunderbird still locks up with the processing message. At this point, I want to know if 1) there is an online interface that I can try, and 2) If my emails can be salvaged somehow.

I tried the troubleshooting tips on the web, but I can't even get into the folders, even in troubleshooting mode.

Good morning

Since this morning (05/03/2026) Thunderbird freezes within a minute or two of opening the program.

Everything in the program freezes up. I cannot even close it.

I am running Version 140.8.0esr on a Windows 10 PC.

Initially I was getting a pop up warning message that ask me to confirm if I wanted to send an email with attachments of over 20 MB. There were 3 or 4 such messages. I had not tried to send such emails.

I checked the Outbox in Local folders for old messages, but it was empty. I also checked the Unsent messages files in Local Folders in the Profile folder. I deleted the Unsent Messages.msf file to no effect. I renamed and replaced the Unsent messages file. Also no change.

I checked for crash logs but there are none.

I have run out of ideas as to what to try next. Does anyone have any advice?

Whilst using TB the screen went white with dozens of little tabs along the top of the screeen with what look like page icons, as the app became 'not responding'. Re-loading didn't help - same screen. Re-starting didn't help. I uninstalled and re-installed TB but it is stil the same. Opening in Windows (11) safe mode produced virtually the same result except for a few seconds I was able to open the hamburger menu and select trouble shooting. Opened in trouble shooting mode showed several alerts of 'failed to connect with servers' (outlook.office365.com imap.gmail.com and Yahoo). Then it shut down as before 'not responding'. When open, TB is using some 80% of available memory., and I can only close it by using Task Manager. I'm a complete dunce at this stuff so, if anyone knows a way out of this hole, please use simple English! Thanks, Jeff
