Today when I logged onto my MacBook I found that my Thunderbird desktop application is corrupt. When I attempt to open it states "You can’t open the application “Thunderbird” because it may be damaged or incomplete." Screen shots included.

I last used TB with no issues on Oct 27th.

I have over 20 years of TB emails that I do not want to loose.

I have backed up my profiles folders (there are 3) from >Go>Library>Thunderbird>Profiles

My first question is that I thought there were multiple locations of profiles. One for local. But I can only find the above profile.

My second question is how to I go about re-installing? Should I remove the corrupt application first and and then reinstall? What steps should I take?

Thank you!

I have an email account with BlueHost, which also hosts my web domain. A couple weeks ago I stopped receiving emails and contacted BlueHost tech support. The agent had no clue why I wasn't receiving email. She said "Can you please click on acocunt actions and remove the account and re-addd it. [sic]" I did that, and I was again able to receive emails. But then all my old emails -- sent and received -- had disappeared. BlueHost was able to restore my Inbox emails back to May 19, but was not able to recover any Sent emails. I have a backup of my Thunderbird directory from April, but would like to recover all of my old emails, which apparently still exist because my current Thunderbird Profiles directory contains files corresponding to deleted email folders. For example, my Inbox had a subfolder -- call it ABC -- that was deleted and is no longer visible in my Inbox, but I can find files ABC (no extension) and ABC.msf in my Inbox.sbd folder. My Sent.sbd folder also contains files ABC and ABC.msf. These folders are in C:\Users\aaa\AppData\Roaming\Thunderbird\Profiles\aaa.default\Mail\mail.aaa.com (with "aaa" representing my personal identifiers). mail.aaa.com contains files Inbox, Inbox.msf, Sent, and Sent.msf, which seem to contain my old emails. (Inbox is 132,151 KB and Sent is 289,829 KB, and the file dates are from a couple weeks ago, when I removed and re-added the email account.)

Is there a way that I can recover the old emails?

Recently, all folders only display the Thunderbird start page with a donation request that cannot be clicked away. And when I disable the display of the start page in the settings, nothing is displayed at all (see screenshot).

Thunderbird upgraded itself to version 140.2.0esr (64-bit). I also got a new browser tab for Thunderbird 140 Eclipse. However, now Thunderbird will not receive any new emails. I can see that they're out there via my mobile phone. I don't get any kind of message when I try to receive emails. It's as if it's totally ignoring my request. I have two email addresses - it will not work for either.

Additionally, I am able to send emails out to a gmail address. So the only issue seems to be receiving emails.

Specs: - I have a Windows 11 laptop. - I'm using POP3 (I know, my friends are giving me crap. But I want to keep my emails on my laptop, not on the server. I'm old school that way.).

I've tried requesting emails the following ways: - Hit F5 - Click on File | Get New Messages for | All accounts - Click on File | Get New Messages for | Current account - Click on File | Get New Messages for | <choose the individual account>

I've tried the following to resolve the issue, without success: - I saw online where someone mentioned a bug with the new version. They suggested creating a default account. I already had a default account, but changed it in hopes that it would help. However, it didn't. - I deleted the global-messages-db.sqlite file to try to rebuild the profile (this was also suggested online). The rebuild was successful, but I still could not receive emails.

Can you help me? Thanks very much!

I have an account on Ubuntu that has several mailboxes. I need to shift (migrate) this to a new computer with Debian 13. So far I have tried to follow the idea of copying the hidden thunderbird folder. When I start Thunderbird it has a "Setup your existing email address" page.

This is not easy.

Thunderbird just updated to 144.0.1 (64-bit), and now I see a blank area where message list used to be. This true for all accounts and all folders.

I used to see this issue temporarily after compacting folders, but usually (but not always) went away and messages showed up. Sometimes I had to close and restart TB. Now even that wont bring up the lists. I'm dead in the water. And, yes, I did reboot my computer as well. Screenshot of this state attached.

Thanks for any help--it's urgent. Bert

Thunderbird doesn't open. I suspect because it opens every message I get or send either in a tab or a list or both. Then there gets to be too many of these. I didn't ask for any of these things! Why can't I just get messages like I used to, and not have to constantly be concerned with closing tabs and closing lists? It is ridiculous, and now the program won't even open. I know I am asked to be polite, and it is the programmers who are at fault, not the community volunteers. But we are not allowed to contact and complain to the programmers!

I have 1 computer that shows bars at the top and left side that I like. The one at the top shows Get messages, Delete, Reply, Reply All, and a few more items. The one on the left side shows icons that are for Mail, Address Book, Calendar, Tasks, and Chat. I have another computer that doesn't have those bars. I have attached a screen shot from that computer. Both are running T'bird 140.4.0esr (64-bit) and both are Win 11 machines. I've tried everything I can see to get the 2 bars to appear on the 2nd computer. I hope someone can tell me how to get them to show up. Thanks, Mike

I can't figure out how to get a threaded view for a conversation in Thunderbird to behave the same as a threaded view for a conversation in Outlook.

1. From what I can tell, the ASCENDING setting works as expected: a) Single messages and thread topics in the selected folder are sorted ascending by date b) Messages within a thread are also sorted ascending.

2. The DESCENDING view does this, which I feel is confusing: a) Single messages and thread topics in the selected folder are sorted descending. For threads, it weirdly uses the timestamp of the FIRST message in the thread instead of the most recent message. b) Messages within a thread are sorted ascending instead of descending.

3. I would prefer the DESCENDING view to do this: a) Single messages and threads in the selected folder are sorted descending. For threads, it should use the timestamp of the LAST message in the thread. b) Messages within a thread should be sorted descending instead of ascending.

Is there a way to get behavior 3?

Thanks!

Can anyone tell me how to set up the THUNDERBIRD TO ALWAYS LOG-IN into its own Messenger and avoid the Yahoo's interference with his INADEQUATE Messenger format - this should not be high-science question but I have difficulties to find an information in the HELP-section - thanks, Tony H. ...!

I am running Thunderbird 141 on Windows 11. When I open the task tab, it says: "Please select a calendar that supports tasks". I have tasks on two gmail accounts. But it wont let me select either of them (or my other account).

Two Questions:

1. I have invested time to setup all my accounts on my mobile after importing the setup from the Thunderbird from Windows desktop. How can I automatically import all of the setup from either my mobile or Windows Machine to my macbook?

2. How can I use Bitwarden password utility on my mozilla Thunderbird? i have checked and there is no add on for it.

I use Thunderbird for my emails on a Windows-Desktop. I still run Windows 10 as the computer is too old to upgrade to Windows 11 and I have signed up for the extended Maintenance.

In Thunderbird I have set up filters to organize my mail. When I wanted to change one of my filters a few days ago, I was not able to do so, as my Menu in Thunderbird doesn't show the ->Extra Option any longer. My Thunderbird-Version is up to date (140.4.0esr (32-Bit))

Any idea, how I can access my filters and maintain them again?

Thanks for your thoughts and your support

I recently transferred my Thunderbird email to a new Windows 11 laptop. Everything is ok, except the font size in received emails can best be described as very tiny. I've tried everything to increase the font size, but nothing helps. My screen has a resolution of 2880x 1880 Any help would be much appreciated. Thanks.

I have had an ongoing problem with Thunderbird being unable to log into the various mail servers that I use. I've tried repeatedly to solve this problem and have been able to cure it in the past by clearing the cache, but it recurs over and over again. I cannot keep wasting my time like this. I'm an independent contractor and I need to be able to use my e-mail client consistently. I've got work to do! This morning, it's suddenly decided that it cannot log into any of the three services that I use.

Is there a lasting solution to this problem? If not, please tell me and I'll move on peacefully, but please don't keep me chasing my tail for something that cannot be fixed.

My windows 10 PCs are running ver 140 (and say they are running the latest ver and no updates are available, but my W11 Pc is running v144. When I try and copy profile from 140 to 144 about 1/3rd of the directories are missing. I usually do to this prior to going on a trip when I copy from desktop pc running W10 to laptop with W11. Last time I did this there were no problems as both were running v140, but now that the laptop upgraded itself to ver144 that's no longer possible as a third of the directories end up missing - things like Inbox, Trash, Drafts, Archive etc which are fairly important. I've paused all Thunderbird updates until the problem is resolved. Can you help please?

After changing my settings for incoming and outgoing mail servers, Thunderbird still times out. Also, I changed the yahoo server settings to imap but the server type shows as POP. Is that causing the time out problem. Here are my current settings: Yahoo Server Type: POP Mail Server Server Name: imap.mail.yahoo.com Port 993 Username: dragracers@cox.net Connection security: SSL/TLS Authentication method: OAuth2 DOES NOT ask for account or anything else.

Description: Yahoo Outgoing server: smpt.mail.yahoo.com Port: 465 Security and Authentification: Connection security SSL/TLS Authentication method: OAuth2 User name: dragracers@cox.net Does not connect with a time out approx. 30 seconds later.
