Thunderbird Support Forum

Hi, I run TB on 2 machines. On one (running Win10) Supernova downloaded automatically, odd as I thought you had to opt in to get it. (The other running Win11 is still on v102). No problem as it looks good. (I'll make any suggestions separately.) But I'm concerned about migration as I have a lot of messages, both archived and in live folders. Judging by some forum responses version 102 should still be lurking in the background. Is that right? And if so what's the migration plan once Supernova is out of beta? And as I was about to move storage location from C: to D: for space issues, is it best to hold off until Supernova is fully live?

Thunderbird is completely unusable in the latest release. Attempting to set up a gmail based account results in

"Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to 192.168.1.250. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

That's it. No options, no explanation, no KB articles, nothing. It just doesn't work. But why is Thunderbird trying to open a web connection to my local machine? If it's trying to talk to itself, why can't it? This is clearly an issue with trying to authenticate to Google as it happens after auth, but come on, this is a given requirement these days. If your app doesn't work out of the box (MacOS 13 btw), it may as well not exist for the OS, so this is very confusing.

Trying out older versions was a real comedy of failures as well. Too old and it's just a disaster. Too new and it just self updated to 115 again which doesn't work. So kinda seems like this is not a functional app anymore, at least not on Mac. Baffling. I guess it can only be used with legacy style email systems.

After the automatic upgrade to 115.2.2, I have lost access to all my folders, emails and calendar entries. But I can still see my addresses by using Tools/Address Book, and my filters by using Tools/Message Filters.

When I started Thunderbird for the first time on 115.2.2 I got to the usual message page which had all the tabs of the "open" emails I had when I last closed Thunderbird. But there was no sign of my folders and I couldn't get to any other messages (See first screenshot). I also had a second occurrence of Thunderbird running (I could have hit the icon a second time) that didn't show the tabs I had on the first screen. (No screen shot)

On a previous post here https://support.mozilla.org/en-US/questions/1424153 it was suggested that I try Troubleshoot mode. That made no difference and at that time I had no folders showing, and just two tabs. I suspect after that I deleted the tabs.

Now I get a completely blank page in what is usually the message/folder area. Also the button for the address book above the message pane has now gone disappeared (Second screen shot), and I can find no way of accessing my previous (10years+ of messages).

It looks to me as if something is wrong in the profile.

Where do I go from here?

Following an automatic update the other day, everything in Thunderbird is oversized. There are in fact some things I can no longer see at all! The program has become very difficult to us to read/write emails. See the image below, a full-screen capture showing the problem . There must be a line to edit in the fonfig file to make the display look normal again. Please help me find that line!! I am visually impaired, and life is difficult enough already! tnx, Paul pgschreier@swissonline.ch

nubi Linux 22.04 LTS. 1st time install TBird 115 appears success server setup; however the Verify fails with timeout circle running forevever. See attached screenshot.

I recently installed the Flatpak version of Thunderbird Version 115.0.1.

I can no longer start Thunderbird from the command line. It is supposed to run by using the command flatpak run org.mozilla.Thunderbird. When I issue this command nothing happens.

I can however start Thunderbird by using rofi. When I use rofi to start Flatpak Thunderbird, it runs perfectly.

I do not have any problems with any of the other Flatpak applications that I have on my system. Prior to updating Thunderbird, I did not have any problems with the Flatpak version of Thunderbird that I had installed. It is just this new version of Flatpak Thunderbird that is giving me problems.

I am running Debian Linux version 12.

TB version: 115.1.0 (64-bit) Windows 10 (corporate laptop)

Fresh laptop, fresh install of TB.

When trying to connect email@example.com (not really my email), TB correctly detects that my domain is hosted at Google, configures IMAP and SMTP for OAuth2, and pops up the window to authenticate.

Instead of an authentication prompt, I'm met with this error:

URL: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=<CHOMP>aq8lmia8j<CHOMP>.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost&scope=https%3A%2F%2Fmail.google.com%2F+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcarddav+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar&login_hint=user%40example.com

Text: Did Not Connect: Potential Security Issue

Thunderbird detected a potential security threat and did not continue to accounts.google.com because this website requires a secure connection.

i had the latest version 115 and i decided to install the previous version coz some things didnt go my way. i opened it and its supernova - i lost everything like settings, my local folders etc. how can i go back to all my settings i had in this supernova version?

My mother would like to export her very extensive address book in CSV format for safekeeping and eventually for porting it to a new email address. She recently updated to Thunderbird v. 115. I can find help for exporting address books in previous versions. In v115, under Tools, I can only find that a zip file of everything in the profiles directory can be made. Am I looking in the wrong place? Any suggestions besides downgrading to v. 102?

can i go back to ver 102?? can't seem to find how to do this online importexporttool ng is grey out not avail. on new version i save dozens of emails from thunderbird to my computer for 'eternal' storage in pdf format & remove them from thunderbird but can't find an easy way to do this now if i try to save as they all go to a folder with .eml suffix which i don't want, if i try to print to pdf i have to name ea. file & if i try to save them to jpg i have to say 'ok' to ea. file i tried to do 119 files this morning & gave up, hate upgrades that change such important things

I downloaded the installation file for Thunderbird 115, English (British) edition. When I try to install it I get " Can not create temp folder archive"

The task manager data for Thunderbird is also shown as a screenshot

I want to try out v115, but I'm quite sure it doesn't support the themes/plugins I'm used to (Darko, Mailbox Alert, Manually sort folders, tbkeys-lite).

Before I download and try v115, are there any things I need to perform so that it doesn't overwrite v102 to work alongside, until I know the new version suits my needs?

I couldn't find anything on this "try out", but I suppose it should be possible - you may want to add this to the blog post because I bet many people want to see it in action but are afraid to make their currently stable mail workflow break.
