Probably my falt, the last version of Thunderbird got instaled on my PC. I do not like it, impossibility to read my message on the side of the screen, impossible to reorganise mails via there date after they reorganised themself throw sender order... So, I would like to go back on my old version, probably 143 or 144 ? Does anybody know how to do it without loosing all my data ? Thanks in advance... Pierre A.

I am using Thunderbird across multiple devices. Generally this works well, but I recently created a new sub-folder in my Inbox whilst on my Thunderbird Android account (v13.0) and moved a number of messages into it. That sub-folder is missing when I return home and open my desktop installation (140.5.0esr 64-bit). At home I am running Windows 11 Pro v25H2.

Is there something obvious I can do to bring this sub-folder and its contents into my desktop Thunderbird set-up?

I tried adding the sub-folder manually on my desktop Thunderbird installation but the folder would not appear.

Help appreciated.

Hi! Downloaded Thunderbird on a newdesktop computer, also had it on my old desktop computer, I used to read the emails underneath the email title.

Now it comes on the right side of the screen, i dont manage to change it myself.

I have just had an upgrade to version 145.0 but cannot select any of the optional layout formats that I had in previous versions as they are all greyed out. Why is this?

Hello,

When I try to save attachments from emails directly on my Computer, they never arrive at the destination folder - not individual files nor "save all attachements". Although the procedure '(left button menu - save - [navigation through file system till to the destination-folder] - save here') is "normal" and does not give any error message.

I can only save attachements, when i first open them (e.g. in word), and save them from there in its destination folder. This is quite a complicated procedure .. one should be able to save attachments directly from Thunderbird, without opening it.

What is the reason for this problem? Are there any options, is it a local problem (but it is a brandnew Laptop) or is it a bug in Thunderbird?

Best, Renate Albrecher

I already have Thunderbird installed on a laptop. IS it possible to export my inbox and view the emails on a desktop without having to create an email account on the desktop?

bold text When in "Local folders" , I had icons for "New Message" and a spot that I could right click on to get new messages from certain servers or left click to get them ALL. Where did they go ?

Confused. Version 144.0.1 | Released October 16, 2025 Says 32 bit. I thought I downloaded 64 bit.

Problem: Freezes when I click anywhere on TBird desktop

How do I address the freezing problem?

Thanks Robert

This has just started to happen today. Each message I receive has the Message ID in the message pane header box underneath the date. Please explain why this is and can I stop this happening?

There is no immediate delete "trash can" in the message card view. Why?

Many messages can be deleted as you view them in the card. Additional steps, such as highlight-delete or clicking the dots and then deleting, are extra steps that are not only inefficient but also extremely annoying.

Can this be fixed, or is there a step I have missed to add a trash can to the card display?

I have several accounts in Thunderbird. I have never (intentionally) used the archive option. Yet, one of my accounts now has an Archive folder that I cannot delete. No option exists when right clicking the folder and I cannot drag it to the trash. It has no emails in it, and never has. Its possible its been there a while and I just didn't notice, bu AFAIK its new.

I have gone to Account Settings Copies & Folders...and the "Keep Message Archives in:" is unchecked. Further, I checked all accounts to see if one of those might be 'checked'...just with a folder specified in a different (wrong) account. Not it.

I've restarted. I'm at a loss as to how to clean this up.

Any help would be appreciated.

Thunderbird 144.01...that I upgraded to 145.0 when checking the version to report here. No change.

Am getting this message along with a recurring download of a specific email (keeps coming back even after deletion) that does not allow any other new messages to be downloaded. I do see new emails on my phone but will not read into Thunderbird??

Error: "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

Tried: Troubleshooting, closing Thunberbird and reopening, rebooting windows system, compacting, etc. to no avail....

Every time I want to print an email, the default copy number on my printer menu is shown as 2.

I don't know how, when or why this change [from 1 copy to 2 copies] happened.

I wish to 'reset' the default copy number to 1, so I don't accidentally print a second copy and waste ink, etc.

When I want to print documents stored on my PC, the copy number field on the printer menu is blank, allowing me to enter the number of copies I want - so the issue appears to occur only when I print emails.

OK, so I have 4 different emails on my Thunderbird account. I get the most email from my usa.net (Netaddress.com) account, but that has never been an issue -- as my inbox gets huge I just move the contents into a dated archive.

I have already looped back to the people at usa.net and all of my settings are correct.

Here is the issue: Out of nowhere, a few months ago, when I tried to download my USA.net email, it would stop after 100-200 emails. Also, it would NOT "register back" to USA.net and show the downloaded items as "gone" (I checked my settings; I am NOT leaving email on the USA.net server).

I even tried deleting a ton of emails on the USA.net server side via webmail, and it still just stops after 200 messages max. I then need to dump out what was downloaded to another folder or I get the error below (see upload).

I hadn't changed anything on my settings when this started. USA.net DID start a requirement several months ago RE using SSL, but I didn't have problems when I initially made the switch.

Help, please! When it stops downloading I either get no message, or I sometimes get the message shown.

How to fix please? Again, this is the ONLY email account that I have this problem with; if some kind of "limit" was being hit it wouldn't be letting me download from other accounts, including my "business" email (basically I use USA.net for all of my newsletters, online purchases, etc).

Thanks so much.

On the 20, of October I was forced to re install Windows 10. Kept my data but I had to re install all my apps. With Thunderbird I follow the same procedure I used with Firefox: After installation I copied the profile folder from my backup and replaced the new one. That worked out well. With Thunderbird, I followed the same procedure, all my emails where there but not my local folders. I am attaching several snapshots to illustrate my steps. Image 1 "local folders now" Image 2 "Profile Folder". (why there are 2 sub-folders)? Image 3 "Mail in the profile folder" Image 4 " List of folders in my Local Folders" The are there, how do I get them back on Thunderbird in the correct place "Local Folders"? Thank you for your help again. Regards Ilio Pieroni

I have been reading the posts re this problem; there have been quite a few. Ever since I updated to Win11 (a week ago) and installed the latest version of Thunderbird, I have not had any option to allow external content in my emails. There used to be a yellow bar above the email body with an "options" button. There isn't now. I have tried checking "allow eternal content in messages" in the settings; no change.

There was a suggestion to work around this by pointing at the message and choosing "unencrypt email and copy to...(choose folder)" from the popup menu, and then read the unencrypted message in that folder. The menu I got only had "copy email link" and left me to decide what to do with it. A newsletter in HTML is very hard to read. I don't want to work that hard.

Others with this problem were using Bitdefender, and you seem to have concluded that this was a problem with Bitdefender and doesn't need any further help from Thunderbird. I do not use Bitdefender. I hope you will change your minds and address the problem. I liked Thunderbird before, and now it's turgid and hard to use. Should I downgrade to an older version? If so, please tell me how.

Some time back I learned that going to config and changing "mail.delete" from FALSE to TRUE would change the way deletion worked so that after deleting a message the cursor would move to the next most recent message instead of the subsequent one. I've now decided that indeed I preferred the default setting of FALSE. I have changed it back on my two PCs, both running Win11 24H2 and TBird 128.14. On one PC the direction was changed back to the default direction, i.e. go to the subsequent message. On the other one it still moves to the prior message. I think I have done exactly the same thing on both PCs. What do you think I might be doing wrong?
