Thunderbird Support Forum

Since upgrading to version 115.8.1 I get unable to write email to mailbox . I have three email addresses in my profile. All are POP. One (from yahoo) always hangs and the other two fail intermittently. OS is Windows 10 64-bit at 22H2 level It doesn't matter if Zonealarm is turned on or off. I have over 300GB of free space on disk.

Full error message: 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.

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

What WordPress email setting we should use to to send WordPress transactional emails via Gmail account which has Thunderbird-Gmail App enabled. For example, using FluentSMPT WordPress Plugin?

Or, how to send WordPress transactional emails using Thunderbird mail client, on Linux OS server?

I am hoping someone can help me. I had an email address for years that was a Medicacom email. When we got rid of Mediacom we no longer have that email. I had it linked to Mozilla Thunderbird. Yesterday I tried to disable it. I clicked on remove account but not on the message data. It removed all of the emails that I had in there. I have several things that I need that were just gone. I hope someone can help me retreive them. Thank you.

April 15, 2024 Thunderbird is Insecure There is missing functionality issues

1. How to Disable the "SHOW PASSWORD" Button in Security Settings 2. Either implement with a Password Password option, only to show the Passwords or 3. Allow the ability to Disable the Button

back in 1916-18 the ability to disable the "SHOW PASSWORD" Button worked with with a variation of the following at that time user_pref("pref.privacy.disable_button.view_passwords", true); I believe I created and used chrome.css or chrome.js

At some point this functionality ceased to work.

Now, I have scoured the Net to figure out a Solution simply setting the value to True, gets reset by Thunderbird, TB does not save it. it always reverts back to False and the button remains available and does not disable

I have tried everything, adding it in user.js, settings.js, userChrome.js I put it in every directory, nothing seems to work

Do I have to Lock it? - How? confusing and disappointing.

Please provide a simple step by step Solution to the problem

Thank you

In coming email prefixed with "Me". My research indicates that this is a feature called "pretty names" that can be turned off. Can someone please tell where I can find this "feature" to turn it off? Thank you.

Hello. My email hosting service, UK2.net, has changed it's servers. I've tried entering the new log in information to retrieve my emails according to the new IMAP details. I can't make the connection work. The mail servers don't seem to be recognised. I've included a screenshot of the connection page. Can anyone help? Paul.

I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

I'd been using 115.9.0 for a couple of weeks, and found it cantankerous, but manageable. Finally had the screen looking something like my old faithful 109. Today I started up Tbird, and NONE of the windows came up, except the main menu bar. I found that messages were downloaded (but I couldn't see them), and I could Write an email -- it's screen looked normal, as did the Address Book screen. I clicked on View/Folders and found that only the top "Folders" was checked. When I checked "All Folders", nothing happened, and if I left that menu and came back, the "All Folders" was not checked. Then I clicked something at the bottom of the Folders menu, and the Menu Bar disappeared. I've been unable to get it back. I enclose a screen shot of the current condition. Anything you can suggest is appreciated.

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

I accidentally started the upgrade to 115 and aborted it. The "What's New in Thunderbird 115" now pops up every time I run the "old" version (102.15.1). It is my practice to close all running apps at night before I have the computer go to sleep mode. Consequently I have this message starting my default browser every time I restart TB. It has become annoying. There must be something I can do to stop this. I looked in all the appdata directories but couldn't find anything obvious. I also looked in the update directory but nothing obvious to me there either. Can you provide a fix for this?

I have not upgraded to 115 because too many people are having problems of one sort or another. I do not want to search for help to patch problems resulting from the upgrade process. When problems settle down a bit more, maybe then.

Give that I use TB as my desktop client to access my nyu.edu email (provided by google), and that recently I updated my password as periodically requested by nyu admin When I try to access nyu email a pop up screen come up asking to authenticate with imap.gmail.com. I click next and get a 403 Access Forbidden error (Authentication failure while connecting to server imap.gmail.com.)

Solutions I have tried: 1. Clear cookies, history and cache on browsers and TB; 2. Changed default browsers (Ffox, Ch, Edge); 3. Deleted account in TB and created it again using instructions here https://www.nyu.edu/servicelink/KB0016473 4. Accessed my nyu email on browser to check user name and password. It works. I can access the email.

Nothing seems to work. Still get 403 error. As a result I am unable to authenticate and hence use the email account in TB.

Left Mac Mail for TB (on Fedora). I am trying to replicate my signature from Mac Mail but I can't seem to format it nicely. I had some legal disclaimer text which was small font (8) and gray rather than black. I tried pasting the text into the signature box in account settings but it's just plain text. is there some way to activate a rich text/html editor to make it look a bit nicer? thanks

New TB user here, coming from Mac. I notice my emails look very 'old school' - font wise. I THINK it's because TB is showing plaintext whereas Mac Mail was showing me html, it looks that way anyway. Or maybe it's 'rich text' rather than html. I'm not sure, but it got me wondering, are there any major privacy/security risks of viewing html emails rather than plaintext? I automatically block all images in emails, always have. but looking at Mac Mail it doesn't look like i blocked html as some emails (newsletter type things) show some nice background colours and buttons etc, whereas the same email on TB is just basic font text.

I'd like my emails to look a BIT prettier, in all honesty, but not if that opens major security/privacy risks.

Would be grateful if someone could offer their thoughts on the above please
