Thunderbird Support Forum

About 2 weeks ago, Thunderbird stopped sending emails. I spent a couple of hours on the phone with tech support but was unable to correct the issue. Changed all of the settings several times, SMTP server, port, security and authentication without success. Tech support suggested using their server but that's a pain. Attached are pictures of the error messages. Thanks.

Hi,

Just updated to TB 115.10.1 and right on update it now fails to show the most recent emails in the inbox, They are there as I can scroll up to them but it no longer does that on it's own when opening and downloading the latest.

Any suggestions to get it back to normal operating condition?

I accidentally added a misspelled word to the Thunderbird dictionary.

Its a medical term and I really don't want to accidentally included the misspelled word in future emails.

Is there a way I can removed the word?

Thanking you in advance of your answer.

I have cox comm. for internet and emails, they just changed their server to yahoo.com. Now I cannot sign into thunderbird to send or receive emails.

Hi

Got an earlier version of Thunderbird at home (and sorted fine) but I'm trying to sort the view for folders and sub-folders to be all the same on my work PC i.e Sort By: Date, descending & unthreaded.

Apart from going through every folder/sub-folder, is there a quick way to set this in version 115.10.1 ?

Looked at online help/videos but they refer to older versions.

About a month ago, I created a Thunderbird account...or so I thought. I got a mailfence account. I didn't use it. Today I tried to download a Thunderbird account again, thinking I had done it incorrectly before. Again, it takes me to my prior mailfence account. Now it is asking me to pay for a subscription that I didn't want in the first place.

How do I get a Thunderbird account?

For the record, I went to Thunderbird.net to download it and just followed the prompts for a standard installation. I also restarted my computer. I selected "make this my default email." (I wasn't sure about that but I had tried not selecting it before and it didn't seem to work so I selected it a few minutes later.) Thank-you for your help.

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

I have 3 machines with Thunderbird. A while back I noticed that I had duplicate folders for sent mail (Sent & Sent Mail) and for Drafts. (Drafts and Drafts) I did a search and found a discussion from 2019, but nothing more recent. That one kinda lost me. I just got a new machine and installed Thunderbird again. My Gmail account on the new machine shows the same dual folders. Hopefully someone here can detail a solution in steps for a moron like myself.

Updated Windows 10 on 4/19. After update Tbird displayed: 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. Checked permissions on the mailbox folder=OK. Deleted a bunch of old emails=same result. Uninstalled Win 19 update=same result. HELP!

I am using Thunderbird 115.10.1 on Windows 11. T keeps deleting my saved passwords. T takes a very long time to load. There are no saved passwords and I enter them all with the options to save. I check the passwords in Settings and they are all there correctly. When I next run Thunderbird it may or may not have them still saved. I check the Settings and they have gone; so I enter them again and they are saved OK. But then they are deleted some time later. I cannot see any pattern in the failure. I wonder if there is a problem with the outgoing server setttings. All the passwords are lost whether imap, pop (Ionos), hotmail or yahoo. Is there a way to clear out my profile or is this a problem with this T release. it did not happen until about 1-2 months ago. My profile is on a local NAS. Generally T seems to be quite unstable ; I get Not Responding too often.. Thanks

I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

I had to reinstall Windows 10 home , a clean install (all data on discs are lost) I used the windows backup settings and revoverd that majority of my files but how can I recover the emails from Thunderbird ?

I created my email signature and saved it as an HTML file. When I add it in my account settings, it displays the logo I have as a blank box. It also adds extra spacing in between each line. How do I get it to display the way I saved it?

Other than just the setup, how do I get Thunderbird to use "POP" rather than "IMAP" protocol for email? Until March of this year, I had Thunderbird setup as a "POP" client for email downloads from Frontier. And, then Frontier moved all of their email services to Yahoo and in the process, my Thunderbird wound up using "imap.mail.yahoo.com" instead of "pop3.frontier.com". I don't want IMAP - I want POP. So, I tried changing that in Thunderbird setup to "pop.mail.yahoo.com", but it does not respond.

Cox.net has discontinued e-mail, transferring all accounts to Yahoo.

If I 'add' my new Yahoo account to TB, can I combine future emails and future sent mail with the existing Cox.net history data in my TB account?

Thanks! phil

Posted this before, got no answers, not even a "no, there's no cure for that." Hoping for better this time.... My inbox suffers from disappearing email sometimes, and using the properties>repair cure works okay as far as I can tell (if someone emails me and doesn't ask about it later, how would I know?). But it has happened frequently enough, half a dozen times a month or more, that I do the repair by default pretty much every day just to be safe. That's easy but still a pain. Does nobody in MozillaWorld know a more permanent solution to free me from my constant missed mail paranoia? As I said, a reasonably authoritative "No, there isn't" is perfectly fine and much better than radio silence. Regards!

Recently all cox.net emails transferred to yahoo mail but kept the cox.net address. I prefer the Thunderbird format for emails, more options. How can I add them to Thunderbird? I already have them in Thunderbird with the cox.net address but no new emails are coming in on the ones that have already transferred to yahoo mail. (They didn't all go at the same time so I am still getting emails on the ones that didn't transfer yet.) Thanks.

I have read almost all messages on this website on how to turn of threading, none of them work or they are not available. 1. No option within the hamburger menu to turn off threading 2. mailnews.default_view_flags = 0 - tried this also, doesnt work 3. read every single option in all available settings, nothing that i can see refers to threading

Someone please help, its driving me crazy! thanks
