Thunderbird stopped working on my old Mac Mini (2014). I bought another used Mac Mini (2018), running on Sequoia 15.3, and hoped to install Thunderbird on it, but so far I can't. When I try to set it up, it says my account is recognized, but when I click done, I get the message "Unable to log in at server. Probably wrong configuration, username or password." I suspect it's the configuration. I tried my old Mozilla password, when that didn't work, I created a new one, but that didn't work for Thunderbird either.

My email comes from my ISP — AT&T — whose email service is powered by Yahoo. When Thunderbird stopped working on my old computer. I started using MyYahoo email (same email address), but I'd prefer going back to Thunderbird, which is much better for archiving and directing incoming email to folders I create.

Please help.

I downloaded Thunderbird on my wife's computer and entered the information for four email accounts. The first three were for twc.com emails and the last was a bellsouth.net email account. The three twc email accounts connected and downloaded emails from the server. However, nothing happened with the Bellsouth account. When I tried to send out an email from this Bellsouth account, TB timed out after about a minute. The account server settings looked fine for both incoming and outgoing. I then tried the same Bellsouth settings on my laptop that also had an installation of Thunderbird. It successfully installed the same Bellsouth account and downloaded emails from the server without issue. So the credentials and settings I was using on my wife's computer were correct.

I went back to my wife's computer, trying to see what the problem was. I noticed in the passwords table, only the password for the Bellsouth inbound.att.net server appeared. The outbound.att.net entry was missing (both the inbound and outbound passwords were there in my laptop's TB password table). So, I uninstalled the bellsouth.net account and after restarting TB recreated my wife's Bellsouth account. Nothing changed and the password table still only listed the inbound.att.net password.

What would you suggest? Do I need to delete my wife's Bellsouth account from TB, exit TB, then uninstall TB and start over with a reinstall? From what I've read, it looks like the reinstalled TB will automatically find my wife's profile from the previous installation. Correct?

Thanks

I am locked out of my account because I get the message "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot?" I then reboot and get the same message when I try accessing Thunderbird. I tried uninstalling but I get that same message. I installed the latest version anyways and it works until I close it and then try to reopen it and I get the same message. Any ideas?

Hello, I am lost, which is why I am turning to this forum for help. I have a professional Gmail Workspace account (in this format: pierre.richard@aile.association.fr). I recently changed my laptop, and I can't log in on the new freshly installed thunderbird ( 128.7.0esr (64 bits) ). On my old computer, which ran on Windows 11 with the same settings, I had no issues, but since switching to the new one, it’s impossible. I put my settings automatically detected by Thunderbird in added images. The system fails every time because, supposedly, the password is incorrect. However, I am certain that I entered the correct password. Here’s what I’ve already tried to do: - I activated the IMAP access on my gmail settings - I tried whith my personal gmail account : It's working !

Does someone know what else I could try to solve this issue ?

Thanks for helping !

Hello,

I would like to know the command line that allows Firefox to propose the creation of a shortcut in the taskbar when Firefox is first run

Example "C:\Program Files\Mozilla Firefox\firefox.exe" -CreateTaskbarShorcut

Thanks

I followed the instructions to install flatpak and then firefox (from the Mozilla pages) and got to the end, but Firefox was not not the path. There was a shell script in/home/edg/.local/share/flatpak/app/org.mozilla.firefox/x86_64/stable/869b4e0279ab4475432b2930ae5d583b7a0e00bac1078b8848d163820a152fa5/files/bin/firefox but it led to /app/lib/firefox/firefox. The /app directory doesn't exist.

Not sure what is wrong.

No audio coming out of any website while streaming using Firefox. No issue with Google Chrome. This started recently. Windows 11 Home Edition Version 24H2 Build 26100.3194

Any help?

Thank you

i uninstalled and reinstalled firefox

i went to settings to make it my default browser

no help

I use Thunderbird on two user IDs on the same Mac, which is running macOS 15.3.1.

I usually run Thunderbird updates on user 1, but this time I ran the it (to 128.7.0esr) on account 2, and I can no longer launch it on user 2. (Note: Neither user is an admin account.)

Steps: 1. On user 2, launch Thunderbird. 2. Get the dialog that there's an update to 128.7.0esr. 3. Click the Restart to update button. 4. Get the dialog that there's an update to 128.7.0esr. 5. Click the Restart to update button. 6. Get the dialog to enter admin ID and password for installing the Thunderbird helper. 7. Enter the admin ID and password and click OK. 8. Get a (surprise) dialog to authorize Thunderbird to discover my devices. 9. I choose to deny.

Expected result: Thunderbird relaunches, now with 128.7.0esr. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

10. Log off user 2 and log on to user 1. 11. Download 128.7.0esr from the Mozilla website. 12. Check the hash. 13. Install, choosing to replace the old Thunderbird in the shared Applications folder. 14. System Settings, About, System report, Applications 15. Verify the signature is signed by Mozilla 16. Launch Thunderbird

Expected and actual result: Thunderbird launches and I can use it normally.

17. Log out of user 1 and log into user 2. 18. Launch Thunderbird

Expected result: Thunderbird launches and I can use it normally. Actual result: Get the dialog to enter admin ID and password for installing the Thunderbird helper.

I'm guessing there's some manner of residual file that's preventing Thunderbird from launching on user 2. I've verified Thunderbird is in the system's Application folder and not in user 1's files.

How do I clear the pending install from user 2 so that Thunderbird will launch for user 2?
