Thunderbird Support Forum

Hello,

I sometimes receive large file attachment while using Thunderbird. My current version is 91.9.1. When I try to save the attachment to local computer, it saves the file as 1KB file size with no error messages or anything. I did not have this problem in the past with older Thunderbird version.

Does this problem happens only in the newer version? I was able to download the same attachment using gmail. I hope that I do not have to go through this every time I get a large file attachment.

Thank you.

I followed instructions posted on a TB fourm on how to generate an app password in order for my TB to work with AOL. I'm receiving mail in Thunderbird but can't send. I suspect that I may not have followed the instructions completely and would like to start over. Do I need to delete the AOL generated password on AOL and create a new one or just create a new one for the outgoing server? Would appreciate any help! JD

Right now, the messages in my threads pane show up in colors associated with their tags. This isn't a functionality I need and it makes it difficult for me to read a lot of the messages. I just want messages to show up in a single color -- black (or white on black would be great, but I don't know how to set a dark mode if one exists). I suppose even better would be the ability to have certain tags affect color and other not.

Any easy way of doing any of this?

Hi folks. I got a popup today advising me to upgrade Thunderbird to the newest version. I thought, "hey why not, I've been using Thunderbird for YEARS, I like it it's great"....so I did I can no longer connect either of my gmail accounts or my icloud account. Is this a known problem with the upgrade? If I wait a bit will "it fix itself"?

Any ideas?

Thanks!

Hi, I want to use Windows Task Scheduler to send command line emails via Thunderbird.

I have found only: thunderbird -compose "attachment='C:\first.txt,C:\second.txt'"

This works. But I also want to include email to, subject, text body and send.

I have tried options like Blat. Blat works but not with gmail.com as they block it. So with Thunderbird installed locally I may be able to work around the new gmail restrictions.

Many thanks.

After a complete hard drive meltdown, I had to re-install windows (10 Pro) and then TB, which is now a blank slate. I have my old profile stored. But in it, my two primary e-mail accounts were POP3 (alongside a number of IMAP accounts) and I was never sure how to switch them to IMAP without having to change the e-mail addresses. And I always quickly moved e-mails out of the inbox into a series of local folders for storage. So pretty much everything I need to reference is in some kind of local folder. So my question is: 1. Is it possible to selectively import local folders from an old TB profile into my newly-installed TB? OR 2. Should I load my old profile and then try to change the two primary accounts to IMAP and can I/how do I do that while keeping the e-mail address? I currently have the new TB on my desktop and the old TB with my profile on my laptop with the "check for new messages" disabled on all accounts. NB I am 60+ and while relatively computer literate for my age, maybe somebody could ... to quote Tom Hanks ... explain it to me like I'm a 3-year-old :0 TIA for any help, Rebecca

I'm a long time user of Linux Mint. Now on 20.3 and Cinnamon desktop. Also a long time user of Thunderbird. Now in version 91.8.1 Always used the "allow insecure apps" in my gmail account settings and used normal password stored in Thunderbird. Google urges to change the authentication method to oAuth2. Tried everything to no avail. Always "authentication fails when connecting to imap.gmail.com" Cleared all cookies, allowed them, deleted all saved passwords, followed all published advise I could find, and nothing. Then I made a brand new profile pointing to an empty dir and entered my gmail address and checked everything. Same result. In despair I installed Evolution and all run fine at the first try. Should I really give up on Thunderbird? Thanks in advance for any help!

How do I change the font size in Thunderbird? I am talking about the font size for everything. The titles, the menu titles, the messages. Everything is too small. Is there a way to see what has changed from default font settings or a way to reset back to default font sizes? Thank you

I made a huge mistake, I was trying to make Thunderbird view larger, now it's much to large to be functional or to make changes or go back to original settings. Here's what happened.

I went into "advanced settings" and changed layout.css.dev.Pixels.Per.Px the size is to large and now I can not view or make changes to Thunderbird. I tried deleting Thunderbird and re-installing it but no luck, the re-install has same large scale issue.

Hi, I have an existing installation of Thunderbird 91.9.1 on my linux system. I have a gmail, outlook and web.de mail each running via this installation (IMAP). My new workmail is hosted by 1&1(ionos). I can log in via web interface. Autoconfig finds the configuration that is (according to their help articles) the correct one to access the Mail via IMAP. Incoming: imap.1und1.de SSL/TLS 993 Outgoing: smtp.1und1.de STARTTLS 587 normal Password Username is my full email address. There have been no typos. I checked 5x, copy pasted, rechecked. Pasted it into the web interface login, and thunderbird before clicking go on each -> tb - no, web - yes domain is talsen.team

I would appreciate some pointers to get this fixed. And yes i did read prior questions regarding this error. It did not help in my case.

I'm trying to help an elderly friend move from Eudora OSE to Thunderbird. I found this closed thread on the forum - and I want to know 'how to back up the Eudora OSE Profile' - or any other help you can give re migrating from Eudora OSE to Thunderbird. (She has thousands of old emails.)

The tech person said,

"May I suggest, back up your OSE Profile, and give it a try.

And the other replied: "I took the tech's suggestion Backed up Euroda files and simply installed Thunderbird VOILA ! When I launched Thunderbird it simply accessed the same files and file structure (and settinge/etc) as Eudora and I didn't have to do anything ... awesome !"

I got a new pc so I copied the thunderbird file from the old pc to an usb following the instructions in this site. I copied back into the new pc (thunderbird) without creating a new account and nothing. I did it creating a new account and nothing. installed and reinstalled thunderbird and copied just the profile folder and nothing, copied just the local folder and nothing , thunderbird always open asking to set up a new account and old profile doesn't get recognized. I need help please cause I don't want to loose my saved mails. I have tried many options stated in this web siete but none of them seems to work. it is very frustrating that such a simple solution from here it doesn't work.

When I open my email, then go to my Bulk Mail folder sometimes I get a message "Server IMAP.mail Yahoo Mail.com has disconnected. Server may have gone down, or maybe a network problem. I mentioned this to a Rogers tech and he said it is not their problem - probably a software/programme problem. Any ideas?

I have lost my IMAP and SMTP connections between Thunderbird v91.9.0 on Windows 10 and two Gmail accounts. One is a standard @gmail.com account and the other is an @my_domain account on Google Workspace. The experience is (almost) the same on both.

Any help would be greatly appreciated.

When I try to read IMAP mail through Thunderbird, I'm presented with a pop-up (apparently from Google) to log into the gmail account with the email address pre-populated in the "Enter your email" field. Curiously, the email address for the Google Workspace account is broken into two parts with the user name left justified in the field, the @my_domain right justified and a gap between them. This is not true for the standard @gmail.com account, where the field is prepopulated with a left justified username@gmail.com. I click the "Next" button and an "Enter your password pop-up (apparently from Google) appears, into which I enter the password and click "Next".

Then I see a pop-up (apparently from Google) which says "Mozilla Thunderbird Email wants to access your Google Account", with "Allow" and "Cancel" buttons. I click "Allow" and often (but not always) see a small pop-up (apparently from Thunderbird) which says "Authentication failure while connecting to server imap.gmail.com".

The experience on the sending side through SMTP is similar. Upon clicking "Send" in Thunderbird, I'm presented with the same sequence of pop-ups (apparently from Google) to enter Google user name, password and permission to allow Thunderbird to access my email. Then there is a "sending message" pop-up (apparently from Thunderbird) which never completes.

Here are what I think are the relevant Thunderbird settings --

Thunderbird used to ask me for my password on incoming emails but this has now disappeared and mail is automatically downloaded when I open Thunderbird. How do I re-instate this? I have version 91.10.0 on a Mac and have a POP3 account. I am still asked to enter a password for sending mail and would like to keep this feature.

Recently upgraded Thunderbird from version 61(?) to version 91.0.1. Could not find my address book. Found instructions on how to import address books. Successfully imported contacts. However, they were added to "abook" address book; not "Personal Address Book" (PAB). Tried to move to PAB; would not move. Tried to copy and paste each list to PAB; could not do it. Screenshot of top left part of address book shown (names partially obscured due to privacy).

How do I move all these contact lists from "abook" to the PAB?
