With the latest update 115.11.0 the existing profile was not identified and loaded. All existing configurations, mail and address book are not accessible. The likely problem is the installer program that uses IP address as a factor in finding the correct Thunderbird account. I use VPN and do not have a static IP address. I have been shut down for several days now and any attempt on my part to resolve the issue has failed. The old email is very significant. Unannounced updates can cause serious trauma for Thunderbird users.

I just purchased a Google Pixel 8a, and needed to install the reader for my Yahoo Mail account. When I searched for Thunderbird for Android, I found Edison Mail+. How does that fit, or is this something I don't want?

Is there - yet - a Thunderbird for Android? If not what do you recommend? I had been using K-9 mail on my Pixel 6a (which, I had understood, was the forerunner of Thunderbird for Android), but it just doesn't want to install on the 8a.

Hi!

How can I sign in to Netaddress with the new Firefox update?

I'm afraid that as I am old and female I haven't a clue how all the information below can help. What can I do with it? As I can't access my only email address, I'm not sure how I can follow instructions.

Fingers crossed for some information. At the moment all I get is 'bad request'.

I recently un-installed an old version of Thunderbird that was showing a vulnerabilty and would not patch itself to the latest version for some reason (old version was in the 60s). I had all mail stored in a non-standard folder on my D drive so that it would be included with my backups. After uninstalling, my non-standard folder is still there. However, the location where Thunderbird was originally installed was removed and that is not included in my backups.

I installed today the newest version of Thunderbird, but I cannot get it to open my old mail. I'm able to login to my accounts, but I need to access the email stored in my non-standard storage file.

I have downloaded the addon cardbook. Now, how do i find my old address books that existed prior to the addon? Please do not leave a single step out on how to migrate back or forward or what ever i have to do to get my old tb moved to the new cardbook tb supernova. Thank you.

Hi. I love Thunderbird! But I cannot use a Gmail account.

It all started when I changed the underlying password for my Gmail account (for routine security). I changed the password too on my Thunderbird client for SMTP and IMAP.

But then it popped up with: https://accounts.google.com/v3/signin/identifier?app_domain=http://localhost& [etc]

it keeps giving me this message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

I've tried to read online what's going on. I've deleted the account and tried to set up again, and closed Thunderbird. It keeps doing this. I've checked Google settings ... nothing untoward. It doesn't have a link to Thunderbird still.

What can I do?

Thanks, Dan

I have a PC that cannot access the Internet. Using a thumb drive, I was going to download Firefox then load it onto the PC. Do you think this will work and if so, how do I put Firefox on the thumb drive (be specific - step by step). Thank you

Upgraded to Sonoma 14.5 on iMac and when trying to open Thunderbird, I get the message "Thunderbird" is damaged and can't be opened. You should move it to the Trash. What do I do?

I'm moving from win 10 to 11 in new PC. I downloaded Thunderbird. I have hidden files showing in new PC so I found where it should be. When I look for the Thunderbird I downloaded it's not there in roaming...so I can't move my profile into the new computer. I have it on a drive read to install, but it's not showing up.

This is my Mac Monterey. My Windows 10 is in Safe Mode With Networking. The last update will not download. That version is 125.0.3. What's available under Windows updates does not download either. Now I am running my antivirus on my Windows to see if it runs clean. I do not know why I cannot apply these updates.
