Thunderbird Community Forum

HI just updated to 140.5.0esr (64-bit) Now all I can see is my inbox and deleted. No Sent or any of the other many folders I could see 5 mins ago ☹️. The server has them all though Some help welcomed!

My Thunderbird has behaved very well for a decade or more. No issues and still the same. My question relates to the delete function. When I press delete I get a warning of a delete email with a chance to go back. I changed this to see what happens and now I cannot find how to return to second chance as this works best for me. Possibly simple but how? regards Replytree

I am trying to install an add-on to enable the transfer of large email attachments but, having tried to install a "selected" Filelink add-on, I receive a message that it cannot be installed as it is not validated by Mozilla. Please advise which add-on is accepted. Thank you.

I got this answer to my problem:

The Send bar has disappeared KAMI 30 sep. 2025 19:35:12 Hi, to customize the toolbar in Thunderbird: Right-click on an empty space next to the Search bar in the toolbar. Select Customize… (Toolbar) from the context menu. A window will appear showing all available buttons and the current toolbar layout. You can drag and drop buttons to add, remove, or rearrange them. When you’re done, click Done to save your changes. This is the quickest way to restore missing buttons like Send, Attach, or any other tools you use frequently.

Unfortunately, the bottons like Send and Attach are not available here in my application!

I had put this up on all the mozilla firefox forums, putting up again, cause it remains unresolved.

Dear Thunderbird,

I have been using Eudora for 20 plus years and migrated to Thunderbird after Mozilla took it over. After my donation, I have observed that the last update that you have done, has a bug.

I would always detach any attachments on my email and categorize them in my set directories for easy retrieval and I have these files since 1991. Off late when I detach a file it deletes it from the email, and saves it to my attach folder, desingated in the options menu, making my inbox file that I backup smaller and managable on a pen drive too. Now when I detach files, it deletes them from the email but the attach directory is always empty.

Please rectify this as it is causing a lot of files being lost.

How can I recover my sbcglobal.net email account that I used in Thunderbird for years It stopped being able to send or receive emessages after a series of Thunderbird updates. I believe that Yahoo and ATT now control the sbcglobal.net domain. Any help you might be able to offer would be most appreciated.

I was forced to erase my PC because it was infected with malware. I saved my Tbird profile to my HDD before erasing. I pasted the saved profile to %Appdata% >Thunderbird, copying 1,777 items. When I brought up Tbird, I got the Account Setup window, so I don't think the profile was actually there. What did I do wrong?

After converting from Outlook to Thunderbird, I can see there are 23 unread mails in my Inbox. My problem should have a very simple solution, but I cannot find any. How do I filter my messages in the Inbox to show only those unread???

In certain instances, I can no longer copy/cut from Cardbook notes. This happened in last few months. I just have time now to post the problem. I know since then Thunderbird had updates and so had windows. I am on Thunderbird 128.5.2esr and Windows 11 and firefox 133.0.3 I used to be able to select a word or many words and then right click. Then copy or paste would show up as option in a list. Now no list shows up. But control c and control v sometimes works. If I control c and control v within the note that works. I can copy from something like Word and control c and paste using control v and vice versa. But if try control c in notes and then control v in website that does not work. And that is what I use most.

Four days ago the Att server started to refuse my password (I assume that was it). After four changes of password, including in Thunderbird, the password keeps being refused. Have exhausted several att agents who can't figure out why it doesn't work. One thought the server settings were correct.
