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?

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

I had to replace my hard drive and now have Win 11. I still have my Thunderbird account, but I cannot access the 3000+ emails in my folders. My Thunderbird started from scratch, no history, no files. How do I access and download my saved emails and folders from before the hard drive replacement? The Geek Squad couldn't help. Keep it simple, I'm not a techie.

MacbookPro needed service which wiped hard drive. Reinstalled back up (to Ventura), but Thunderbird app was trashed. Reinstalled Thunderbird, but I can not see received emails from 2019-2023 (now), but oddly, can see all sent emails from 2020. How do I get my missing emails and categories? The web instructions make no sense to me. As I understand, my profiles are separate from the app, but it is not clear at all how I can toggle from one to another while in Thunderbird. Thanks for your help

As everyone here knows, Thunderbird 115 is a hot mess; sadly, as they cycle through new releases, it sometimes gets worse, not better. It appears from my update history that 115.2.3 was the most stable of the 115 versions. I'd rather go back to 102 but it seems that the profile was modified in 115 so that it is no longer compatible with 102. Thus a 102 rollback might require quite a bit of work to reimport the profile into a clean install. And I have gigabytes of important mail.

I'm not on 115.4.3 and it is close to unusable, as they screwed up regression in a major bug, and my bugzilla on it has sat unanswered, other than requesting I be nice to the devs. So as a lower-risk option might be to roll back from 115.4.3 to 115.2.3. Has anyone tried anything like that, or know the safest way? I don't know what booby traps they've planted to prevent any rollbacks. Thanks!

I am about to lose access to my work gmail account (new job). I used Google Takeout to download all my emails in .mbox format. I then used Mozilla Thunderbird (with the ImportExportTools NG add-on) to access the emails. They are currently available in a folder called WorkEmailBackup within my local folders section on Thunderbird.

I would like to add these emails to my pre-existing personal hotmail account. I have set this account up on Thunderbird. However, when I drag the WorkEmailBackup folder into my hotmail inbox (in Thunderbird), not all the emails are copied over. Thunderbird says there are 7730 emails in the WorkEmailBackup folder, but only 2212 will copy into my hotmail account. I have tried several times, but the transfer always stops at 2212 emails, and I can see that emails are missing. I have also tried highlighting the emails individually (rather than copying the whole folder), but have had the same problem.

Please help :(

When I looked at my profile I find that there are several folders created for each of my email addresses at different times. I had wondered about the possibility of clean install of each of the accounts (IMAP) so this would pickup everything from the individual servers. Then copying across the local folders and my address book. Is this possible/feasible? Would it just be easier to import everything? Where is the address book stored. I also have TB backed up on an external drive (insurance). Thanks

Problem: Thunderbird hangs up on Macbook and iMac. It opens to the normal view, but if I try to do anything, I get the beachball of death. I used Mac migration assistant to install from Macbook to iMac. Before the installation, the Macbook Thunderbird worked fine, but after the installation, neither worked. My PC installation works fine, as does Apple Mail on my iOS devices, so it is not a provider problem.

Solutions tried: restarting in troubleshoot mode, restarting iMac, turning off access to Apple Contacts, turning off antivirus (Norton), creating new profile and copying existing mail data into the profile folder, and renaming various files in the profile folder.

Results: None of the solutions I tried provided access to my email. I can open the new profile, but that requires that I reenter all my email account information and copy the emails for each account into the new profile (I use POP). The problem may be with the prefs.js file, since if I rename it, Thunderbird doesn't hang, but would require me to reenter all my account info as if it were a new profile, and all preferences would be lost.

Question: What is the best solution for this problem? Is there anything that would work better than reentering the account info -- e.g., can I make any changes to prefs.js using a text editor or some other utility?

I am getting an error that "you have launched an older version of Thunderbird" Every time I try to open my email. I was using the latest beta version up to three days ago and the program got corrupted for some reason. I did try to install the latest beat online beat 2 .

Thanks, Al

hey all

when i downloaded and installed Thunderbird beta it imported my account settings fine, but lost the list of automatically allowed image loading emails/urls so now i have to add everything again.

if i switch back to the stable release, how can i make sure this list is kept?

feedback - you may want to provide some way to automatically import that going between versions so its not lost (i couldn't find it after switching) and even export all settings for backup - i remember having to change region etc info (im in Australia).

Hello and thanks in advance to anyone offering help, very much appreciated. My partner hates computers but has to deal with them for her home based work. After long struggle she has got to grips and enjoys the functionality of Thunderbird. Her old laptop is on the way out and we got her a new upgraded machine (Lenovo windows 11). a 'friend' tried to solve a problem in the past and created a second account locally on her laptop that mirrors the incoming emails to her main BTinternet mail account. however, sometning went wrong and she hasd over 15000 duplicated emails on the second back up account. We wish to istall Thunderbird on her new machine as she doesn't like to windows mail app and noy 'enjoys' (sic) the thunderbird, especially coulering emails for easy reference. we were told that if she deletes the second account, all of the mirrorede emails on the desired/to keep BT account will also be lost. we are now wondering if it is possible to download Thunderbird onto the new machine and somehow not import the unwanted account when she signs in etc. We are hoping also that when she downloads and installs and signs in.... (the above query accepted) that her folders will also import and be populated. But!... only for the account she wants. i hope this has been clear? The server is imap from BTinternet email thnaks to all who read this far

I tried to access a shared Gmail account via Thunderbird, let's say shared@gmail.com. I don't have a password for this account, but when I log in in the browser, Gmail knows it is a shared account and says "log in using another account" and then I can use personalmail@gmail.com to log in.

I tried this in Thunderbird by adding shared@gmail.com and then using personalmail@gmail.com as the OAuth2 option. I found some tutorials at university websites that use this, but all with Exchange and not Gmail. At first this didn't work; I got an "incoming server already exists" error. By using imap.googlemail.com I circumvented that and the account was added, but it showed the personalmail@gmail.com inbox, not the shared@gmail.com one.

Is there a way to make this work or is it simply not possible?

I'm trying to migrate old messages (stored under pop) in an outlook .pst.

choosing Tools, Import, then selecting Import from Outlook, immediately gives a "No Profile Found" above the import tool.

I'm not even clear if this is referring to a Thunderbird profile, an outlook profile, or possibly a file in an import directly somewhere?

anyone have suggestions?

Thunderbird 115.0 on Linux/Debian is unable to verify and install addons from website. It just freezes when I try - and cannot even manually install addons that I download using Chrome. I even totally deleted all files and folders and reinstalled Thunderbird 115.0 from stratch... what happened?!

I found that after total removal - if I install a earlier version... that I can verify and install addons, but not with version 115.

I also found that I cannot import profiles from zip or even uncompressed folder. I confirmed the profile is less that 2 gig (1.2 gig) - so size of the profile should not be a problem.

Earlier this week, when Thunderbird updated, I lost access to Thunderbird on my PC. The program is not on my PC. However, I can still get my email on my iPhone and the cloud.

How should I restore Thunderbird? Should I just download and reinstall it? I just want to make sure I still have access to all my old emails and contacts.

Thanks! (a long time Thunderbird user)
