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?

As of today Cox is moving all email services to Yahoo. I have been using Thunderbird for Cox.net email. I have about 40 existing folders under cox.net. Yahoo now has Cox.net and is providing my new emails so I still have the same email address and can access it through webmail. What is the best way to transition this from the old Cox cox.net to the new Yahoo cox.net on Thunderbird and keep all existing folders? Thank You

Help -> About "Failed to check for updates."

This has been going on for over a week. I have downloaded and applied the installation program multiple times (>3). The problem persists. What is going on, and how do I fix it? Thanks

Sadly, my old Windows 10 PC crashed, and I'm migrating to a new computer. I have a backup of the old default profile folder (9k7faw1z.default), but not of the entire Profiles folder. I have tried to import this old default profile using the import function in my new Thunderbird install on my new Windows 11 computer.

Alas, I get the error message "Import failed unexpectedly; more information may be available in the Error Console." I looked in the error console, and it's empty.

Is there a better way to import my old data from my old default profile folder? It's 3GB of valuable data and I'll be in a pickle if I can't access it.

Thanks very much.

When I transferred my icloud email account to TB only a few of the 15 folders were transferred. Troubleshooting first with Apple, I was told to delete the account and re-create it. I did but that did not restore to lost folders. How can I get the rest of my folders to transfer?

We have recently enabled background updates in our organization, however I noticed that a requirement for this to work is that Firefox needs to be run with the default profile at least once after the feature is enabled. The issue we have is that not all users are actively using Firefox and therefore they are not being updated. I realize the security flaws won't be exposed if it's not in use, but management doesn't like seeing out of date browsers. Is there a way to force auto updates on all device where Firefox isn't not being used. Background updating is working for the majority of those that do use Firefox.

Also, we do have a couple of users reporting a credential prompt when updating from 119 to 119.0.1. These same users had no issues updating from 118 to 119. I have not figured out why this is happening just yet and why only for a handful of users so far. Would anyone have an idea why that is happening?

Why is it that every time Thunderbird updater installs on my laptop, my taskbar link to it becomes unfindable and I have to 1 click on it so that Windows says it can't find it and would you like to remove it so I can then say yes, 2 wait until the taskbar link disappears, 3 go to my desktop icon for Thunderbird and right click to have it pin to the taskbar (AGAIN!) What does updater do to the taskbar pinned icon that it won't work until I remove, replace it, and go back to work??

Updater should NOTHING to do with any of my taskbar icons, let alone the one for Thunderbird. Tell me something I don't know.

Thanks Lance M.

I made a mistake and installed Firefox in the wrong location. I uninstalled and attempted to reinstall where I wanted the software to be.

The installer now tells me that I had Firefox before and will only reinstall it in the previous directory. No other option is offered.

I am LONG used to being deprived of user choice by the likes of Microsoft or Apple, but Mozilla SHOULD KNOW BETTER.

Can you help?

Thank you.

I have tried multiple suggestions from the help site. Still cannot get Thunderbird to accept settings -

 Protocol:    IMAP
 Hostname: imap.mail.yahoo.com
 Port:           993
 Security:  SSL/TLS
 Authent    oAuth2

What am I doing wrong?

I use Thunderbird for my work email. Since early October, I have had difficulty accessing the internet using Thunderbird. I can access my work email account through the web, but that is a bit clunky. I have no problem accessing the internet via Firefox, and I can access my work email via Thunderbird if I use my phone as a personal hotspot. Is there a setting on Thunderbird I need to change, or is my problem more with my internet provider (Quantum Fiber)?

Good day,

When moving email servers from Webmail to Zoho, I logged in to all the emails I wanted to backup/copy on my machine and made a copy of the IMAP folder. Fast forward, I want to restore/read from these legacy emails locally on Thunderbird on a different installation, and I'm finding it difficult.

I copied the folders back into the IMAP folder of the new machine but nothing happened.

I would appreciate help with this restoration.

Best,

Firefox bookmarks exported from old Windows PC to html file. File transferred to new Windows PC and imported into Firefox. 'Bookmarks Imported Successfully' message seen. However no bookmarks visible in Firefox bookmark menu. Suggestions please?

Good morning, I can't get to my stored emails. After reinstalling Windows, my profile could not merge with saved on my computer emails. I've moved profile folders to (...AppData\Roaming\Thunderbird\Profiles...) and inbox/sent/spam/trash .msf files to Thunderbird instalation folder. Unfortunatelly, I still don't have access to my saved emails. Could You please help me with this issue?

-hi friends,

I am desperately trying to import a contact book into TB. In CSV format. All I get get is 100's of unreadable records. My version of TB is 115.4.3 (latest). The import tool provides no info whatsoever about the CSV format. I found a bit of info about the format on Mozilla. I only need a few fields for the record. First Name, Last Name, Home Email, Work Email. These are supposed to be field numbers 1,2,5,6. I made a CSV file according to this, but import is as said impossible. Has anyone had any luck with this? regards /peter

Hi,

I am running out of space in my email account. Is it possible to export specific folders of emails out, so that I can delete those folders (and the emails in them) to make some space. I don't want to do a full export out, just those specific folders, so that if I ever need to refer back to those emails, I can import just those back in.

Is this something that can be done?

Thank you.
