Whenever I use Thunderbird (TB) I get the following error message:Thunderbird is damaged and can't be reopened." This file was downloaded on an unknown date. What is the problem and how can I get rid of the error message.

Hello; I have been using Mozilla Thunderbird for many years on my PC and was wondering if I can start using my account on my Ipad or Iphone as yet?

I have been using the same Email Address and Thunderbird for Downloading my Emails for over 10 years. Now Thunderbird will Not Install. Am getting a strange Error Message ... Authentication Error : Unable To Log in at Server. This has happened on 3 machines. Why is it now impossible to Install Thunderbird on Windows 10 machines.

My LongTime Email Address is [edited from public] @Juno.com

Got a new macbook, did migration from the old to the new. Thunderbird failed to migrate. The icon on the desktop did, but it is not listed in the application list. Both are running the same software version, Tahoe 26.5.2. Talked to Apple, they tried to help, but in the end, they answered that it wasn't their software, so contact Thunderbird. Thoughts???

I can sign in with my google account, but when I come to the installation window with Pop3 and SMTP another password is requested. I don't know which, and there's no possibilty to get a new. Please help Jens

I Googled Thunderbird and received this link: https://www.thunderbird.net/en-GB/thank-you/?form=support&utm_content=post_download&utm_source=thunderbird.net&utm_medium=fru&utm_campaign=donation_2023&downloaded=True&download_channel=esr It asks for a donation of varying amounts. I donated £15. I received an email thanking me for the donation Thunderbird <give@thunderbird.net> Whenever I click download I'm returned to the Donate page. Are these URL scams?

My apologies, but I am not good at searching documentation and Q&A history without a glossary and ontology,

That is to say every (software) ecosystem has their own culture (tacit knowledge) and language (jargon)

I want to install mail user agents and web browsers on diverse systems, from e.g. RaspBerry Pi / RiscV etc. to desktops, laptops, on-prem hardware, and multi cloud distributed virtual platforms.

It would be nice to have a subset of the same server configurations and User Interface / Ergonomics descriptions (CSS) everywhere.

Regardless of machine architecture, kernel distribution, package manager, ad nauseum.

I used to be able to do this with trusted hash verified source or binary (reel-to-reel tape) or SHA256, e.g.), and trusted certificates. (e.g. pgp)

What we used to call tarballs for source, and RC configurations per user and per (virtual) machine.

I am SICK of Jenkins / Ansible / Dpkg / apt / yum / yaml / Nix .... as well as Snap, Flatpak, etc. etc. All in incompatible versions. I used to be able to create self-extracting shell archives that Just Worked on everything from mainframes to personal computers.

I CAN compile and run and modify ancient FORTRAN, COBOL, APL, LISP, and SnoBol without these headaches. I got paid very well to do this for Y2K in 1988-1999

Please take your time answering this screed.

Hello!

I have installed Thunderbird 150.0 on an Ubuntu 24.04 desktop using a downloaded TAR installation method. I have done this, as I use OWL for Microsoft Exchange accounts. OWL works better with the current version of Thunderbird.

I have created a desktop launcher (thunderbird-150.desktop), which works fine, except that the software icon is the generic Gnome gear. I have read that specifying the WMClass correctly in the launcher file (in /usr/share/applications) is the solution, but this does not seem to work. It is current set as WMClass=thunderbird. I have also noticed that the /opt/thunderbird/icons folder does not contain the Thunderbird icon.

Can anyone help me to fix this annoying issue?

Many thanks!

I've been having a number of problems with Thunderbird recently and I'm hoping that deleting and reinstalling the app might help. But I worry that I will lose emails by doing this. I'm also wondering if the numerous folders I've set up will disappear as well. The issues I've been having, by the way, are emails consistently going into the wrong folder and, most recently, constantly being asked for my passwords. (I have emails from four email addresses being downloaded by Thunderbird.) I've had the password issue in years past, but it always seemed to resolve itself.

Hello, I went to https://archive.mozilla.org/pub/thunderbird/releases/ or perhaps it was from https://releases.mozilla.org/pub/thunderbird/releases/ and downloaded the thunderbird-60.6.1.source.tar.xz package, unarchived it and am now stumped :) How to proceed from there?

1. Where can I find the release notes for Thunderbird versions?

2. I mistakenly installed v148.0 from the release channel, when I really want the ESR version. This article says, " "Still unsure which channel to use? Start with the Thunderbird Release channel. You can always switch later if your needs change." and this thread says that one can perform the necessary downgrade by simply deleting the compatiblity.ini file from the profile folder. However, the current release channel version (149) and the version I have installed (148.0.1) are far ahead of the ESR version (140.8.1). I have already configured 8 IMAP accounts and 4 add-ons and would like to retain my existing profile. Can I simply downgrade by deleting the compatiblity.ini file from the profile folder or do I risk data corruption due to changes to the data structures? Can I simply install ESR 140.8.1 over 148.0.1 or do I first need to uninstall 148.0.1?

Will thunderbird run on an iMac With a M4 chip? I’ve tried to move the app from an older iMac to my new one and all I get when I open it is a message that it’s corrupted,

I have downloaded Thunderbird from official Mozilla homepage. It seems to be installed correct. I got the icon and a question : should we start Thunderbird now. I answer yes. Then I get the message : Thunderbird is not found ? but I have just loaded it ? I am running windows 11 and I have got newest upgrade.

Hope you can help me out. Thx in advance. Regards Thorvald Antvorskov

PS I also have a PC running Linux Mint. Loading Thunderbird here was no problem.

New computer, trying to install Thunderbird. "Download" created a file called Unconfirmed 750544.crdownload which isn't executable and doesn't seem to do anything. How do I proceed to do an installation?

I'm trying to switch from Thunderbird ESR (140.8.0esr) to release (148.0). Following the Mozilla support recommendation I'm running the 148.0 setup and trying to install it to the same directory. While doing so I'm asked to restart the computer. After doing so I'm required to restart setup but continuously asked to reboot the computer. is there a zip version of the installation? if not How to overcome the restart issue?

I am trying to re-install Thunderbird on my wife's old Gateway desktop. I downloaded version 115.18.0 and tried to install it, but get a message saying it can't be installed because my OS is 32 bit. I thought the SuperNova would work for both 64 and 32 bit OS platforms. (It does work on my Toshiba laptop, which is a 64 bit Win 7 machine.) If this version of Thunderbird will not work, what about the last version that will. It was installed years ago. Thanks, Peter
