Thunderbird Support Forum

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

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?

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'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?

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.

I am running Thunderbird 115.5.0 on a Win 7 Pro PC (yeah, I know). I recently retired and am trying to change from my work e-mail settings to my personal Gmail account. I have the incoming server set to pop3.gmail.com and the port to 995. Authentication is SSL/TLS and normal password. The outgoing server is set to smtp.gmail.com and authentication is No Authentication, with port 465. When I click on the Get Messages icon Thunderbird doesn't seem to do anything. Is there something else I need to do, or does one of the settings need changing?

Thanks!

My Plusnet Mail account is fully operative out of Thunderbird in Windows 10, alongside my outlook.com mailer. I am attempting to duplicate this in a new Win 11 PC and finding it difficult to duplicate my Win 10 Server Settings, due to the ambiguities thown up in hoping to duplicate the Win 10 Tbird 'Server Settings' in the Win 11 'Set Up Your Existing Email Address' questions page.

Win 10 Tbird set-up page confirms my POP Mail Server as 'POP', 'relay.plus.net' and 'Port 110', the Outgiong Server as 'smtpmail.plus'.net' and Username as '"my-name@plus.com".

The Win 11 Tbird 'Server Settings' page (after my own inserted Mail address and Password) includes: 'Incoming Server' protocol as 'POP3' Host Name: (auto-selected) '.plus.com' Port: (empty) Username (empty) - I elected to insert email address "my-name@plus.com".

'Outgoing Server' Host is (again) 'plus.com' Port - empty - and finally (again) ' 'Username' (empty and complered as before with) "my-name@plus.com"

Note: Despite the (fixed) message "Thunderbird will attaempt to auto-select blank fields", the final result advises: "Thunderbird failed to find the settings foryour email account".

Am I making wrong assumptions as to what should be inserted?

After crash, I had to reinstall Windows. After I enter correct address and password, Thunderbird won't connect. I suspect that my two party authorization set up with mail.com is the problem. 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!

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.

I am trying to set up a new email address on Thunderbird but comes up as a POP account. I then set it up on another computer and it comes up as IMAP. I have tried setting up the IMAP manually but Thunderbird rejects. I have uninstalled the app and re installed it.

Hey everyone,

I've recently come into Thunderbird and I love using it - however, for my Gmail account, Thunderbird only downloads 24 messages every time. It started with 300, but it has decreased exponentially over the past few days.

I have about 30k emails so obviously I need the syncing to be faster than just 24 emails every minute. Is there anything I can do to fix this?

Thanks in advance
