I am using 64bit Windows 11 Home. This happened suddenly without any changes on my part that I know of.

Thunderbird suddenly started freezeing right after startup. The only thing I can do is login with the master password then the regular thunderbird screen opens, but I cannot click on anything. Soon after the screen is greyed out. However I can close the program down with the red "x" in the top right corner. It opens a dialog that gives me the opens to close down or wait to respond. The close option works.

The only hint I can see from the frozen screen is that the local Folder seems to have a problem as a subfolder has now multiple copies of itself. It seems to create a new copy of that subfolder every time I try to start the program.

So far I tried reinstalling/updating TB, as I assumed an update had maybe malfunctioned, (it was stuck on version 128, since I could not open TB for about a week now) but upgrading to to version 138 did not help. I also tried starting TB in troubleshoot mode, which made no difference I also tried starting TB while windows was in safe mode, which made no difference.

I read around but people that have problems with TB freezing seem to not have the freeze happen before they can do anything.

I assume something is wrong in my profile, maybe the local folder? But I have no idea to fix anything, since I cannot do anything at all in TB.

Any help would be appreciated! Thanks!

I exported Outlook Contacts to a .csv file and imported giberish to the Thunderbird Personal Address book. Can the giberish be block deleted? How should the Outlook Contacts be transferred to Thunderbird? Secondly, I exported Outlook Contacts to gmail and have used them on the web based gmail app to send messages. Don't remeber how the gmail contacts got to the Thunderbird Address book, but they don't work. The first message I sent from Thunderbird from my wife's gmail address to my hotmail address produced the following error:

Sending of the message failed. An error occurred while sending mail. The mail server responded: The recipient address <Steve Thompson (sthompson2486@hotmail.com> is not a valid RFC 5321 address. For more information, go to

When I receive an email documenting an online purchase, it is my habit to print the page that tells the amount of the purchase and the vendor; I use the printed pages to keep my credit card up to date.

This has worked very well for many years. But now all of a sudden, sometimes Thunderbird imposes a rather long delay when preparing the "print preview" prior to printing the page. It's inconsistent; sometimes the page preview shows up instantly and sometimes it is a matter of many seconds. I have made no change to the printer or its connection (although Epson does from time to time issue updates to their drivers). No other application on my computer - not even Firefox - seems to suffer this delay; only Thunderbird.

This is with Thunderbird version 128.10.1esr, as well as with the previous 128.10.0esr

HI I am having a nightmare. Updated windows last night before i went to bed, started the PC this morning and thunderbird wont connect to my mail server....So i cannot send or receive emails.

i have been going round in circles for the last three hours searching help articles, but none of them are helping.

i checked the update history and apparently thunderbird was updated last night. But i cannot find a way to remove the update.

i have tried trouble shooting mode, but there is no actual trouble shooting to be done there, just a page full of jargon i dont understand.

I have tried removing and reinstalling thunderbird, thinking that i would need to add my accounts again and that would detect the right settings. But upon reinstalling it opens with the accounts and settings stil in place, so if there is a setting causing the problem, then its being transferred to the new install.

at one stage i clicked on the "repair folder" button in account settings, and that instantly removed all of my emails from the inbox, so i have lost all my emails (which i really need)

I have installed outook, and that talks to the server without any problem. So i tried to import the settings from outlook, but thunderbird tells me that it cannot find an outlook account to import from.

I have tried turning of defender, still dont work

I have no idea what else to try, so i am at the end of my tether with it.

I have copied the text from the trouble shooting page, just in case it makes any sense to anyone....but i dont want to post it here because i am not sure if tere is anything in there that puts me at risk if i post it?

The user can access their email so their account username/password is stored correctly in Thunderbird, it's just not making it to the calendar subsystem.

Failure is 100%. The user can access their calendar from the previous version of Thunderbird and by using another app on their phone.

2. I tried to find the my profile and it showed where it was - but that directory did not exist. I finally was able to make a new profile and the directory showed up - but then the default-esr profile disappeared and now I can't find it and neither can Thunderbird. Is there a way to find where it went? I don't believe I delete it, it just went away. This is the message I get:

Your Thunderbird profile cannot be loaded. It may be missing or inaccessible

Have always set up accounts so they download all messages to hard drive.

Since 3/27/25, it is as if it never officially logs the downloads as downloaded, so it downloads each day as if it hasn't been done since 3/27/25, marking all of the messages since then as new.

File is very large so want to try fixing without deleting entire file.

Tried the 'repair this folder' but that didn't work.

Having trouble identifying the exact folder on the hard drive to delete since there are several different accounts in the Thunderbird setup.

Thunderbird started crashing randomly about 2 days ago, however, after restart, it would remain running if I switched to troubleshooting mode. I removed an add-on from Bitdefender in troubleshooting mode.

Today I can't even open Thunderbird-- it crashes on launch. It won't launch even if I hit the Shift key or if I turn off antivirus.

Here is the most recent submitted crash report:

Crash ID: ⁨bp-b52cd345-636f-445a-ab4c-764ca0250114⁩

Can someone please give me guidance on what is going on and how to fix it?

I have a LocalFolder on a USB stick to move certain mails to, sometimes manually, else using filters on incoming mail. There is no need to compact it. When TB does compacting it fails on the LocalFolder, reporting not being able to compact files.lst. How can I restrict compacting to the mail folders proper only? Since moving emails and reading the archived works flawlessly with LocalFolder, the problem could be related to the owner of the compacting process. Anything I can do to cure that? /HGS
