Hi, I just noticed that my computer has been infected by a trojan called "HEUR:Trojan.VBS.SAgent.gen", and I can't remove it via Kapersky...The trojan is found in the inbox file in Thunderbird. So it's not a file that I can remove (it's all code). Kapersky stated that these two files are the source of the Trojan (they are not found as an e-mail attachment in my inbox, it's all code in the inbox file in Thunderbird):

P000009384:Emirates_Marble-pdf.gz and P000009384:Emirates_Marble-pdf.vbs

So I'm simply wondering how I should go about to remove this trojan from my computer?

Hi, T/bird working fine upto Thurs night Feb 26th then yesterday morning I got pop up windows asking for login credentials. Nothing had changed. Tried logging in thru them put it errored: <<

               Something went wrong

We could not sign you in. Try again from a different device. >>

 I can log into my Yahoo accounts using Firefox so passwords isn't the issue

 I've read thru a number of threads on here and elsewhere but no solution so far. K9 is working on my Android phone and my wife's and her T/bird is working on her PC. Just checked versions, she is on 140.8 ESR and I'm on 148.0. Both running Win 11 Pro.

 Tried changing from OAuth2 to Normal, pop window asking for password but that doesn't work

 Seems to me to be an issue with Ver 148.0 as my wife's working

 What am I missing?

When I let thunderbird compress the inbox and other folders, the not read flags on all new emails get reset as if I have read all of the new emails. Compressing the inbox and other folders should have no effect on the flags showing a message has not yet been read. That only makes sense. The not read flags getting reset started happening several versions before 145.

Okay, I currently have two issues going on, both repercussions from transferring Thunderbird to my new computer. I'll limit this post to one issue!

My transfer to the new computer was not taking; followed instructions but no profiles were loading. I thought that perhaps this was due to my initial problematic installation of T-bird decades ago, where I eventually wound up with a choose-user-profile panel that worked fine with its default setting...so I lived with that easily (see image). Thinking that this was causing the inability to load profiles on the new machine, I tested whether I could delete the never-used profiles in that panel. After just one deletion, that resulted in the "Couldn't load XPCOM" error described here: https://support.mozilla.org/en-US/questions/1360766 Following the instructions on that page to do a repair installation (to the letter), starting T-bird now results in the attached "profile missing or inaccessible" message.

Please advise: Am I doomed?

Thanks for any honest advice. (yes, my Thunderbird installation is big: seven or eight addresses, many local folders, a large history and archives.)

hi today thunderbird started showing yahoo popup login and after adding credentials i always get "something went wrong.We could not sign you in. Try again from a different device." Also popup once closed it opens instantly.

i can sign in normally from browser. thunderbird version is 147

is there any fix about this?

thanks for any help

regards

I have used Thunderbird for many years and and have loved it. However, recently my "Local Folders Inbox" have been extremely slow (deleting emails, reviewing an email, etc.). I have tried every suggestion that I have found without any change: reducing emails in the folder (down to about 75 remaining), compacting and repairing the folder, deleting and rebuilding all of the msf files and global database, disabling all addons, empty trash and junk, clear the cache, disable hardware acceleration, exclusion in antivirus, etc. It has become very frustrating. Any suggestions would be greatly appreciated.

How can I get the "send" button back in my menu. I am not offline. I am receiving messages and can write and save messages to draft but there is no SEND button in my menu anywhere to enable me to send messages out.

Updating my Address Book in Thunderbird v148. The darned thing does not permit two people to have the same email address or phone number - pain in the "A" to say the least !

A "send later" button came up one morning instead of the usual "send" button. When I clicked on the write button to see where the "send" button was, several choices came up but when I clicked on the "write" choice I lost the other choices and now can't get back to the original write button and still no "send" button appears anywhere on the menu. I can save messages to Draft but still can't actually send them. I can still receive emails, just can't send them! Help!

I have rules. Email goes to folders based on rule. I want to reply to an email and have the reply stay in same folder. How do I fix this to work again? What is happening only some out bound emails go into "sent" folder.

Hi,

I need some help! Thunderbird used to have archive settings in which I could choose to save my e-mails locally in my archive folders with 1 file per 1 email and not everything that's in a folder saved to a single file.

How can I get this back? Is there some hidden settings that can be accessed to get it done?

I need every email in one file! I'm going nuts trying to sort years of e-mail duplicates. If I can have a file per message, then I can at least use my PC duplicate file program to compare file content and find the similar ones. But with everything of one folder in the same archive file I'll be cursed to have to manually go through thousands of e-mails by hand! So if there is a way to return the previous archive format (*wdseml files??, it seems?) then I want to know how to set that setting.

Alternatively a local folder duplicate e-mail cleaning tool? There used to be some but I couldn't get it to work now!

My wife's inbox has over 24,000 messages. I'm moving messages whose senders are the most frequent to folders. This ends up having to move over 100 messages at a time, which is taking forever. Has anyone found a faster way to move multiple messages into one folder?

I am installing Tbird on a Windows 10 instance that I am recovering from backup. There is a default profile that contains a folder for a user in an IMAP domain that no longer exists. Tbird won't start and just spins with a message about a missing IMAP user.

I copied the profile to another backup folder. And then uninstalled and re-installed TB. The "AppData > Roaming > Thunderbird > Profiles" folder(s) are still there but empty. When I start TB it says: "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." The old email is not important now. Should I delete more folders in AppData, or what should I do next?

Hello all:

After migrating to a new machine I finally have TB set up and running nicely. As I checked the individual settings and C: folders for the e-mail accounts under the server settings for each account (there are two, law and business), and the local folders (for long term e-mail storage, under Local Folders, Local Directory settings), I discovered the C: folder for the Law e-mail account is gigantic - when I check the properties in File Explorer it comes back as 331 GIG, yes, gig. More disturbing is that most of this appears to be "dark matter" that does not "show up." I total the visible files and folders inside that location and it is roughly 150 meg.

For comparison, the folder directory for Business e-mail account is only 24.9 gig, and the directory for the local folder for long term e-mail storage only clocks in at 11.1 gig.

Any ideas why the law firm e-mail account C: drive storage would be this large, with so much of it not visible?

Thanks for any thoughts.

I want to be able to search my 20,000 emails if needed in the future. I have shut down the actual email account. I don't want to lose them. I do have other email accounts I am using Thunderbird for.

Is there a spam file for thunderbird? I haven’t been able to find one. Xfinity has a spam box on my site. I had mail sent to me and could not find them on thunderbird or Mac mail but I Katerina found them in the xfinity spam folder..

After reinstalling Sonoma (before I had Sequoia) and Thunderbird on my MacBook Air, I cannot find any emails from April 2023 to January 2026. I use the POP option in Thunderbird for my main accounts (the two from GMX). I have tried various solutions and requested support, but nothing has helped. What can I do?
