Thunderbird Support Forum

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.

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

Hi, I have upgraded my computer and Thunderbird, however only the INBOX folder is loading.

I have followed the instructions to migrate the folders from the 'Profile Folder' on the old computer, the data has transferred but is not organised as folders, as on the old computer and of course on the main server.

I don't mind if all the data is not on my computer so long as the Folders are there, empty or not but organised in as they are on the main server.

I'm wondering if I selected an incorrect setting while setting up the account within Thunderbird on the new computer.

Thank you and kind regards, Mark.

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?

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).

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?

When I try to set up Thunderbird on a new computer, it won't connect. And Thunderbird changes the port settings that the provider uses to something else. So I can't use thunderbird with my email address: sheilah@got.net

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?

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)

After having tried to learn to love Supernova for several months, I cannot. In fact, I have come to loathe, despise and detest its user interface. Are there settings in Views that will give me the old look and feel? Is there a skin I can download. If I cannot I will leave TB after decades of use even if I have to go back to (shudder) Outlook.

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

Hi, I kept OS Snowleopard around for years too long in order to keep using Eudora. I finally got fed up with viruses/crashes, having to rebuild the mailboxes, but I was never able to find anything to take its place and have frankly been limping along ever since. I regularly need to find things going back months, years, and even decades. It used to be simple with Eudora. Recently, one of my parents passed away and I'm kind of the family scribe, so I really need to pull together all the past communications, from Eudora (going back to almost 1990), gmail, yahoo, my website, icloud, my college alumni address, my Ronin Institute address, my 15 Sonic addresses--and there's probably a few I'm forgetting offhand. I really need to consolidate them. I tried various email clients, including years ago a previous version of Thunderbird, but they were a lot of work to set up and couldn't handle all the email addresses.

I see better reviews of Thunderbird now. Can Thunderbird really handle all those email addresses? Since my Eudora mbox files are still on OS Snowleopard, and I'm running Macbook M1 with the latest OS now, what's the best way to incorporate the entire archive of messages and also start hopefully wrangling current messages (like I haven't been able to since I had to stop using Eudora)? Eudora pretty much only did POP well, and I actually did appreciate having my data on my own computer, but now there are some email accounts I'd prefer as IMAP and others as POP. Is it possible to mix them? Is it possible to download AND keeps messages available for viewing by phone? This situation has been a problem for me for years--I was just wondering if there might be any volunteers at Mozilla who might be willing to spend a few hours on the phone with me to help me bring my email into the 21st century? Nearly every day of my life I have to let someone down over something I can no longer do or find because I don't have Eudora. But the problem doesn't go away just because I find another program that does some of the things Eudora did--I really need some help integrating everything. Thanks so much for all you do!

Hello community, Is there a solution to integrate a Microsoft Exchange email account into Thunderbird? It simply does not work, because there is neither POP3, nor IMAP, and also no certificate. :(

Thanks and best regards

System is win 11, latest TB, personal gmail account of long standing. I want to use TB as my email program for gmail. After installing TB, it asks for my gmail login and password, and recognizes the account, defaulting to IMAP, Oauth2, etc. When I press "done", I get a google screen saying that TB want authorization to access gmail files. But when I press "allow", the TB page shows an error message under the password field reading "Unable to log in at server. Probably wrong configuration, username, or password." I understand it is looking for my gmail username and password, and these are correct. I have tried this many times, including with variations: removing and reinstalling TB, creating a pw just for TB in gmail (subsequently deleted). I have read all of the gmail installation help notes at Mozilla. Most relate to a 2022 change in gmail re Oauth2. Nothing helps. Any advice?

Haven't been able to download incoming emails on this laptop. They are downloading on my Tablet. I'd be grateful for any ideas about what I can do to rectify this. Not too complicated - I'm 83!!anks

Hoping something will turn up on my Tablet Th

I am s-o-o-o gd tired of this happening. Every time it does, I spend days-to-weeks trying to recover a working edition of Tbird. Why can't you build updates that don't lock a customer out of his/her own emails.

I don't know how or when, exactly, it happened. I use Win11pro which is up to date. I have one Tbird install on dropbox so I can access all my emails from any of four different machines. It worked yesterday (on two machines at any rate, I didn't use the others). Today, no matter which machine I log into, I get an message stating that I ' you have launched an older version of Thunderbird. A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and ad-ons again. For more information . . .italic text Then it gives an 'exit' button and a 'create new profile' button.

1) I did NOT install a new version of Thunderbird.

2) Insofar as I can tell, the version on Dropbox has not changed so nothing should have altered the profile.

3) I do NOT want to create a new profile -- I have years of data in calendars and emails across multiple accounts.

4) the 'more information' link doesn't work.

Why do you periodically do this to me, Mo? Why can't you make changes that don't destroy a person's account(s), profiles or data? Why do you put up such a useless message without a utility to restore things to the way they should be?

5) I have been searching the internet for hours and I don't see a solution to this problem.
