I have trouble downloading the newest version because it says that Firefox has ended support for Windows 8 and Vista.

But I DO NOT USE THESE OLD VERSIONS - I DO USE WINDOWS 10 on this computer.

Could you please let me know how to fix this in plain english so I can easily do it myself - I am no computer wizzard.

Your help would be greatly appreciated. Please write your answer to my email account: [removed email from public] ,

Thank you, Chris

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

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?

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 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

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 currently am running FF vers. 109.0.1 64 bit on Win 10 pro. I don't like what I've been reading about the latest update, my machines are old and I'm not ready to upgrade so I don't want an even more overloaded/uses up more CPU, etc., version of Firefox. I don't have complex needs in a browser, so some of the "upgrades" haven't been useful for me or have made using FF more difficult.

  I found a list of what I guess are older versions but no information was provided on how to choose a version of say v. 110, to make sure it's the right one for my laptop and/desktop (or the one that will work w/the fewest problems) that it's in English, etc.   
  My impression is that FF is mostly worked on by people who have a variety of needs & interests so increasing sophistication is what they want and that's fine, I'd like to keep using FF w/my current machines, w/as simple a version ,ie., useful for an unsophisticated user.    Is that possible?    If so, I'd like to upgrade to 110 64 bit or perhaps 111 64 bit unless either or both had huge security holes, etc and many users found they weren't very functional.   I do have security software.

Saved all my email messages from my old Office 365 to a local folder as we were migrating to a new Office 365 account. Now I have the new Office 365 email configured and working fine and I am trying to restore the messages from the local folder back online. When I try to copy them nothing happens but on the program bar at the bottom left it says "message service.copy message is not a function" Searched around seems like no one has this problem. Cannot find anything on how to solve it and copy back my messages to my inbox. Can someone help me sort this? Thank you

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 shut down my PC for 3 days early July, -rebooted on july 5 , new version of Thunderbird was installed since then I cannot complete the new configuration - agrees the account is good, but fails to complete. I have replaced the new version w/ newest version on july 12 , same result - cannot complete setup , fails w/ error message "Unable to login at server- probably configuration , user name or password "

I opened 2 firefox accounts and I only want the account that is tied to [email removed]@republicanmetals.co

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
