Hello, It's been a few days Thunderbird freezes when I want to save a message on the computer (save as). When I close the saving window which is not responding, it automatically saves the message on my desktop. The file where the last message was successfully saved is still existing so I don't think it is a path problem. I have tried to restart it without the add-on but it doesn't change anything. And it is up-to-date. Anyone knows what the problem could be? Thank you! Estelle

I Shift/Deleted an email in my UNREAD search folder, & all emails in the folder disappeared, as well as the same unread emails in my Inbox. This happened twice in the last few months, with two different accounts (personal and business), both times on the UNREAD search folder. The emails are still in the profile - i opened the profile in Notepad and searched for them. I've given up on trying to get them back into the Inbox (spent several hours with aid from AI), but would like to continue to use Shift/Delete withut this happening. Thanks. Geoff

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've been trying to find a way of synchronising Thunderbird data, principally addressbooks, messages and calendar data, between several PCs. I've tried to do this with a file synchronisation program called Allway Sync but it's become clear it's not just a case of copying changed data between the profiles of the different systems.

It seems the only way to do it is by exporting the profile data to a zip file then importing it to the other systems. That would be a rather clunky solution but I could live with it. However the size of the profile folder on my main workstation is now around 5GB so that doesn't appear to be possible.

I should be extremely grateful for any suggestions on how to accomplish the synchronisation if it is at all possible.

My main workstation is running Windows 7 Professional SP1. The others are running Windows 10 Home and Windows 10 Professional

hello, i had a friend and his father needed urgently to migrate his thunderbird with 1 email to a new computer but he wasnt able to setup the emailaccount in a new german client. i helped and the problem was that the setup asks for the password but it meant the password from the emailprovider to allow thirdpartyapps access. please consider to improve the german setup wizard by adding a new textline to clearify. best regards

new computer. Downloaded thunderbird. Added old email accounts. I have 4. I cannot send emails out with primary account. I can get secondary emails to send out. SMtp is comcast.

I am looking for a way to disable the attachment preview pop-up for incoming emails. Almost all attachments I receive are PDFs and it doesn't work with them, only showing a black screen. Further, the popups cause my auto-hide taskbar to keep unhiding and getting in the way of my work.

Hello, from time to time my Thunderbird on my desktop PC running windows 10 doesn't receive emails, while they arrived on my I Phone 8. Checked my Telstra web mail, all emails are there so what is stopping getting to my desktop PC? I thought the Thunderbird receives emails than synchronize with my I Phone? As you can see from my 2 images the Telstra is up to today as is my I phone But Thunderbird is 3 days beyond. Tomorrow it may back to normal or the next day? I am returning to this message the next day 16/06/2026 1 more message on my I Phone, still nothing on my Thunderbird.

An other problem I get with Thunderbird is that a message appears on the right bottom of my screen: "Mozilla Thunderbird Connection to server mail.bigpond.com timed out" and/or "failed to connect to mail server imap.telstra.com" If I try to send an email after the above notifications, I get the "Connection Refused". I know than to just walk away. I am using Starlink as Telstra here doesn't work as I am on the fringes of Melbourne in a BLACK HOLE. Any help will be gratefully received. Thank you for reading this.

I've been using Thunderbird on Windows 10 since last year sometime. Currently I'm on version 151.0.1.

I've 4 x mailboxes here and since yesterday, 3 of them show me an unusual message when checking for emails. I tried attaching a screenshot but although the screenshot uploaded, I couldn't find a way to insert it here. But the message says Unable to write the email to the mailbox and asks me to check if I've write privileges (which I have) and to cheek the available disk space.(currently 101GB free).

The message is happening 2 or 3 times each day and lasts for about half an hour, then everything works fine again. Has anyone else seen this??

My Address Book appears to be old and out of date. There's at least 10 years of emails in there somewhere. Random old emails are there, but what's visibile is not really useful here and now. How can I restore at least some degree of usefulness?

I just had a support session and the tech was unable to solve the problem. We tried installing a new version of Thunderbird and importing the messages over from the default install and it just freezes up. He tried replacing account settings with the account settings from a previous version and that didn't work either. He suggested contacting Mozilla to see if there was a way to import messages from the frozen default to my new profile.

Hello,

I want to make Saved Searches

So the 3rd step is to choose your folders.

I have a TON of folders and mostly I want to

Start from all folders and only unselect a few of them.

But here it starts from all subfolder collapsed and all folders unselected.

So for me the first step is to manually expand all folders, and subfolder and subsubsubfolders and so on.

And then go down the entire list and select every single one.

And THEN start from the top of the list again and now, choose which one in particular I want to exclude.

I know this sounds like, I should just check the ones I want to include.

But for some reason, that feels completely impossible to do. I can only unselect the ones I don't want and it feels impossible to only select the ones I want "which is all except a few"....

Usually, I never make it to the end and just give up before I get to the stage where I would start unchecking the ones I don't want.

So, this is the reason for this question.

"In Create Saved Search, Choose Folder dialog, how to select all and expand all folders ?"

TB 68.9.0 (64-bit). I'm using this version because I'm used to it.

Scenario:

• I am viewing the message list, eg the inbox
• I click a message
• The message is highlighted in grey with a thin blue outline. However it does not have focus: for example when I hit delete on the keyboard nothing happens
• When I click the message again (after a delay, so it's not a double-click) the message is highlighted in blue and I can now delete it from the keyboard
• When I delete it, grey highlighting (but again not proper focus) moves to the next email. If I want to delete that from the keyboard, I have to click it to make it blue.

Desired behaviour (this always used to happen):

• I click a message once
• It's highlighted in blue
• When I hit delete on the keyboard, it is deleted and focus (blue highlighting) moves to the next message so I can delete that from the keyboard immediately.

I've tried rebuilding the folder, to no avail. The config mail.delete_matches_sort_order is set to false, which is what I want (emails viewed from newest to oldest; when I delete one I want focus to move to the next one down, i.e. the next oldest one). As I say, the desired behaviour always used to happen and I don't know what's changed.

After some Windows Updates installation, my computer behaved very erratically, and I had to reset it. After selecting the option to keep all files, it appears to be a joke, as I have ended up having to reinstall almost everything. Regarding Thunderbird, all the files have disappeared including the folder with the profiles, however I did a back of that folder on a separate disk and I need to know if that can be used and how to go about it.

Goal: I have outlook on a windows 10 desktop with many .pst files I want to keep (emails in folders and contacts)/import into TB. I want to set up Thunderbird on a new laptop PC and use TB instead of Outlook.

I'm setting up Thunderbird first on my desktop but I don’t know how to import the outlook files – one Q&A answer says first install an older version of TB that can do the outlook import (I started this and it couldn’t find my account so I got stuck); another Q&A answer says the outlook files have to be ‘offered’ to Thunderbird and may or may not be.

Can I have human help? I’m happy to pay. Otherwise I don’t think I can figure it out and I’ll just stick with Outlook. I see someone else switched to TB and then went back to Outlook. Hmmm. I wonder why?

Thank you so much. It sure seems like a great product you offer but it's overwhelming figuring out how to get there from here.

I have changed the website hosting company from my previous one to scalahosting.com, which in turn appears to be using grok.viawebhost.com as their mailserver.

I was a user of Eudora 7.1 for many years, but because of this change of hosting company, the Eudora email program would not connect to the Scalahosting site.

Thus I was forced to change to Thunderbird. After reading several webposting on this matter, I found and uploaded V17.0.9 and proceeded to convert the Eudora email, filters and addresses to the Thunderbird format.

This was not an easy task, and even with Google's AI assistance, I had to restart several times, but as of today - mid-Jun I have now completed the task of cleaning up all the email, installing the correct headers, etc that allows the Thunderbird program to open and correctly display all of those email without any problems.

I further cleaned up and corrected all of the Eudora filters to the TB format and now have those filters in TB to be able to be installed and correctly are accepted by the TB program.

Like wise with the contact addressee that were in the Eudora NNdbase.nnt file were cleaned up and correctly installed in the TB program.

However, the current status of the TB program is that it does not seem to be able to connect to the Scala Webhosting email site at grok.viawebhost.com. Enclosed is a pic of the supposed correct set up for the STMP at Port 465.

The other Port info from Scala is: POP3 - 995 (SSL) IMAP - 993 (SSL)

But I am not sure what else I need to do to correctly set up this older version so that I can start the collection process of the most recent emails sitting in the mailserver.

Further, it was suggested that I need to update the TB V17.0.9 to the most recent V151 by following the below sequence of updates:

According to Mozilla Support Documentation, this is the exact, official sequence to migrate safely from a legacy version:

Step 1: Run V24.8.0 (32-bit) (This updates the raw database schema out of V17. Upgrades the raw Mbox structures.)

Step 2: Run V45.8.0 (32-bit) (Stabilizes the folder indexing schema.)

Step 3: Run V52.9.1 (32-bit) (The final 32-bit staging version.60.9.1 (64-bit). Migrates the architecture to 64-bit processing.)

Step 4: Run V60.9.1 (This is the critical gatekeeper version required to unlock modern automatic profile conversion).

Step 5: Run V78.14 (This shifts the mail indexing formats).

Step 6: Run V102.15.1 (This modernizes the folder structure configurations).

Step 7: Final jump to V151.0.1 (Updates the background engine to current web standards).

I am looking any advice or suggestions from the Community that can assist me in completing this conversion to the TB program and get it fully functional so I can connect to the Scala Hosting mailserver.

Many thanks in advance for your assistance.
