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.

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?

I had version 102:15:1 up and running after I had new terrible version 115 removed. Now during an update TB/Mozilla reverted me back to 115. Now I do not seem to be able to downgrade back to 102:15:1 again. WHY Help would be gratefully received. Thanks

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.

I understand that Supernova changed the database format of email storage making rollback more difficult.

Well, either I get to roll back to the old UI, or the pre-Supernova Tbird, or I'm done with Tbird and done donating. This update is absolute shite and not being warned of the changes it would make was really, really shitty.

So how do I roll back, oh geniuses who developed this new shite Tbird?

I wish to upgrade to Thunderbird 115 and how do I get to the app so that I can click on the upgrade. Simple question but I have forgotten how to get out of the first screen to the app. Pat Blackburn, uepat624@gmail.com

Hello, I moved Thunderbird data to a new computer according to your instructions via a USB drive On the target computer everything goes well until point 9 of your instructions. "Choose to replace your current data when prompted." However, this screen does not appear. I open Thunderbird, but then only the screen to enter the email data appears. So Thunderbird does not open with complete data. What do I do? I'm wrong.

Greetings Jos

Why did you upgrade my software. Now I can't send any emails. What the h did you do, and would you please stop changing the software if it's working!!!!!! I DIDN'T NEED ANY UPGRADES, IT WAS WORKING JUST FINE!!!! Everything keeps timing out. F you. I can't send anything!!!!!!!!!!!1

I'm sorry if this topic has already been answered.....and I know it has.....but I have been reading and trying things for almost 3 hours.....I need help!!! I have at work the Thunderbird eMail that goes through a different server. I followed the directions and copied the "Moving Thunderbird Data to a New Computer" to a flash drive. I used that and have all the files that were on it, now on my at home computer. It appears that everything is good up to that point. I even get the window that shows that Thunderbird recognized my other server's setup, however when I choose "OK" it gives me an error message that it is already on the server. I can see the Thunderbird email system on my home computer. But I can't get it to show any of the emails that I know are there from my work computer and I can't get it to download. I'm not sure if I have been clear enough, but I hope either someone can help me with what I have provided--or provide me with directions on how to do the install--EASY directions--because I'm unable to follow what I have found so far. And a reminder--I do still have all the files that I copied to the flash drive--so I could start all over again, and it would not be a problem. THANKS SO MUCH IN ADVANCE!!!

I just want everyone to know, I will NEVER again update Thunderbird. I do not like the constantly changing layouts. I do not like layouts changing without my consent or knowledge. You are NOT user friendly any more. While some may like your approach, I do not. Frankly it seems that most software is becoming less and less user friendly and more like, do it Thunderbird's way or else. I hope someday, someone will put out a simple email client similar to your older issues. Also, I do not like the continual nagging to update.

I upgraded my MacBook Pro operating system and now have a message that thunderbird app is damaged and needs to be put in trash. Can I trash it and reinstall without losing my data? Thanks in advance for the help!!

1. I am customer of Ionos, formerly 1&1, who host my email address.

2. Ionos have advised me I will be unable to download emails from their server after 25 April unless the email program supports TLS1.2 or higher and they said Thunderbird version 52.00 supported TLS1.2 or higher.

3. I have 2 PCs with Windows XP SP3 and 1 laptop with Windows Vista. Ionos say the only email program I will be able to use after 25 April using the latter 3 devices to download emails from their server is Thunderbird version 52.00.

4. Is there now any means by which one may install Thunderbird version 52.00 onto a PC with Windows XP SP3 or, alternatively, a laptop with Windows Vista?

Every morning when I open Thunderbird I receive the notice that "Thunderbird can't update to the latest version." but I am already running the latest version (91.9.0 as of this writing, screen capture attached).

None of the following have worked to resolve this issue yet:

• Download and install from "Download Thunderbird" link in notice.
• Uninstall and re-install from fresh download.

Any thoughts what I'm doing wrong, or what else I can try?

Thank you.

Not sure where to put this; too many issues at the same time.

- Thunderbird moved the top menu bar to the left, now has unreachable buttons at the bottom due to negative interactions with other menus and window manager => tried many forums, but all changes to ./chrome/userChrome.css are ignored. - the quick filter button was moved from the toolbar to an individual bar, adding one new line above message list, reducing the vertical space for content - new management of borders have negative interactions with window manager (tried both options, with and without decoration, both are ... BAD). making it impossible for window manager to properly resize window magnet to other windows - there are large sensibility zones for decoration management catched by TB that make some buttons unreachable in the left bar, and the window manager gadgets i have below (quick launch and desktop management) - there is a new sensibility zone between the top menu bar and the top decoration of windows that give access to some window manager menu, useless at this place, and it reduced the vertical sensibility zone of the buttons, making the click box smaller, and reducing the effective size of buttons, making them harder to click - the unread message count which used to be a nice light blue is now white in a dark grey box, catching the eye more than necessary, slowing me down, and increasing my brain work to focus on what i need to do. also this value is unconsistent; my inbox is curretly shown with 411 total messages, and 630 unread. If i unfold the folder in left column, it seems i have only 89 unread in inbox, and 2 in one subflder, but, to me, 89+2 is not equal to 630. - the file/edit/view menu bar is now BELOW the actions buttons Get/Write/Reply ... - if I roll up the TB windows in the top decoration, any mouse click in the place where the win used to be remains inefficient. So, TB completely broke E17. A shaded win still occupies the screen as if it's unshaded, and more (about 20 pixels below the bottom decoration). - It's 20y the message list was aligned on the top message, so I always made that box half a message taller than an exact message line height multiple, so that the half line white space was a proof I was at the bottom of the list. Now, the list is aligned bottom, and the top line is shown half. I now have no way to know if i am in middle on bottom of list (plus lift is now auto hide).

i don't have any screenshot from previous version for reference. And half issues are bad interactions with E17 about magnetism, and size of click boxes, and this can't be shown on screenshots; even videos would not help if you can't feel it physically, or never used E17 yourself in the past; you can't know how it used to behave.

All these changes have an intense negative impact on my work speed. They slow me down.

TB had almost not changed in 20y of use, but these changes, at the same time, with so many consequences on window manager ... I can't stand it. 20y of habits lost in one evening. Not something you can change at my age.

I have seen only one improvement (bug fix) in recent TB: "save all" attachements works now fine from the menu under the message, and we no longer need to use Save All from top menus (regression bug between TB 1.2 and 1.5, IIRC).

I downloaded the last version of Thunderbird using OS Ubuntu 22.04 LTS. I can't get past ./configure. "not found" I'm disappointed that I finally made a donation. Ron

TBird 102.2.1 - just updated . . . and discovered that doing so caused several folder modifications I had just completed in the previous version disappeared. Really, really helpful . . . not.

Was in the midst of copying email files/messages to an external drive; 3/4 of the way through, in checking the "finished product" over there on the external, I discovered that -- regardless of what date the email had originally, TBird was changing all of the message dates to today's! That's really, really useful . . . I guess . . . in someone else's reality. My reality is that when I'm backing up email messages I have a reasonable expectation that they will each accurately reflect everything associated with the original(s).

So: How does one tell TBird to leave the original date(s) alone and copy the message(s) intact?

Guess it's now looking as if I will have to start this process all over -- and attempt to not seriously begrudge a program that makes such an unwarranted and unexpected change . . .

Thanks for any helpful information; appreciated.

Hello! I want to make a new totally clean installation of TB to get rid of the grey/italic folders issue (the folders and it's structure is correct on the IMAP server and as well display in K9 Mail on my mobile and none of the solutions posted here, such as renaming the folders etc. did work). What I did so far: - Uninstalled TB - Deleted the profiles folder in the user folder (both in "local" and "roaming") - Deleted remaining TB folders in "ProgramData" and "Program Files (x86)" - Emptied trash bin - Restarted

But... After installation the old folder incl. the grey/italic folders appear again.

Does TB store under different names the previous profiles? How do I force TB to load totally new the folder structure as it is on the server?

Any hints are mostly welcome!

Best, Wolfram
