I have been getting this message since January and am starting to be concerned

Secure connection failed start.thunderbird.net uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

  This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
  If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception… When I click on add an exception nothing happens. I tried closing Thunderbird, deleting my cert8.db file and restarting Thunderbird - no change - same message. I am running Windows 10, Thunderbird version 45.8.0

Help, please ! Thanks, Sarah

I am running Windows 7 and have Thunderbird 91.10. Just went through your instructions to update to OAuth 2.0 (Well done BTW). When I try to get new documents I am immediately diverted to the log in page for my Google Account. Any suggestions on ways to avoid this? Thanks.

How do I create a TLS 1.0, 1.1 exception in Firefox 100.0+ for my legacy devices (NAS), that no longer get firmware updates from the manufacture, that are on my private network and thier configuration is done through a web browser?

 I have been using Firefox browser for a long time, since it was called Mozilla browser.  An answer such as "I'm out of luck." means I will have to look for a new browser.  I prefer not to do that.  I trust the Mozilla brand and like you products and recommend them to my friends and customers.

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

browser.sessionstore.resuming_after_OS_restart = false. My browser still restores on os restart. Startup -> Restore previous windows and tabs is unchecked browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.restore_on_demand = false browser.sessionstore.resume_from_crash = false

I do not and will not manually close my browser session every time I want to shut down my computer in order to get it to do what it's supposed to. Linux sends SIGTERM to all running processes on shutdown. Firefox isn't handling this correctly, obviously, because if it was, then my settings would be getting respected. SIGTERM is the standard signal sent to windows that need to close gracefully and are expected to still be functional.

NOTE: Do not provide windows-specific support to this thread. I am not running firefox on windows, and I do not possess a windows computer or license.

Using FF 101 on Andtoid phone. If I do not use Android's "general" PW then how do I protect FF PWs if I

lend to a friend for a minute? There's no primary PW. So how's it done? Is there any change FF will ever have a primary (master) PW again? Thanks

This isn't a question about the "Multi-Account Containers" addons, I am pretty sure that there was a section called "Container tabs" in the privacy and security settings, and I could use containers without installing an addon some days ago.

I can still access by directly viewing this address

about:preferences#containers

But I can't find it in the settings, and this feature does no longer work.

So I went to read recent release notes from Firefox 100 to 101.0.1, but I didn't find any notes to say this feature has been disabled. Could this be an unexpected result of an update?

My PC died last week and I now have it back with a new hard drive (SSD). It's running Windows 10 and so far I have installed Firefox and Kaspersky Total Security, all of which I used previously. I have now installed Thunderbird but am unable to access my account. The password and configuration settings have been triple checked. Any suggestions re what I can try next please?

I'm trying to add a new account with my student email that is basically a gmail with a different name. When I try to create the account, Thunderbird launches the website that asks for my username and email. That same website will accept my password when using a browser but when Thunderbird opens it will not accept it. I've checked several times, I've even copied the exact same username and password from the browser to Thunderbird and TBird says that it's a wrong password and it absolutely is the right password. I tried to cancel the process so that the account is created nonetheless but when I click on it, Tbird will still try to open that website and will not accept the correct password. Please help!

Ver 100.0 Settings:Startup:Open previous windows and tabs is UNCHECKED. But every time I open Firefox, it opens the last site I had open before I closed it.

This worked before ver 100 and suddenly has stopped working with ver 100.

I even rebooted the computer (Win 10, 64-bit) and same behavior continues.

How can I enable the "ask to save logins and passwords" option? See the attachment. I do not use private mode and saving history is allowed. I can browse saved logins also, but I want to activate automatic infill of them. Firefox 102.0 64-bit

Hi, Yesterday I noticed problem with Thunderbird. When I try to add account (for the first time) i get a message "Unable to login at server...". The problem is, that ive checked each possible problem indicated by people on the Internet: - cookies set as "always turned on" - authorization method set as "OAuth2" - saved password - cleared - proper ports addresses - anti-virus app - disabled while trying to solve In fact, after I click "Done" (after i fill in NICKNAME/MAIL ADRESS/PASSWORD) in order to go to the authorization, the Gmail window pops up (that's great!). I can easily enter my email adress and password, but afterwards "Unable to login at server..." appears. The problem is not tied with THIS Google Account, emerges all the time, even for different accounts. I have no more ideas. Please help!

I have used Thunderbird for years and the login was automatic (stored password) but for some reason recently it's asking for my password and I have no idea what it is. The last readable emails were around 2/2022

The email address is [email]@bee-bradley.com

Thanks if you can help

Hi

I've tried to search for a solution but couldn't find anything. I'm using Thunderbird 91.9.1 on Linux (Ubuntu), however I've tried this also on Windows 10 and exact same problem. I'm using the owl plugin to integrate to Microsoft O365 - that part works just fine. My problem is I've imported a gpg key and when I try to decrypt emails, the lower left bar just says "Loading message" but nothing happens - no error messages or nothing.

I can decrypt the same message using the same key with GnuPG on the command line, so nothing wrong with the key. I've also tried using an external key instead on importing directly into Thunderbird - same result. Is there any logging I can enable that would help me troubleshoot this, google didn't give me any good answers?

Grateful for any ideas. Regards Christian

Hi, I hope someone can help me. I am an author and sell my book through KDP Amazon. Firefox is my default browser but will not let me log in to KDP. No problem with other websites including Amazon.com When I open the KDP log in page it accepts my email address but the password button has a row of asterix right across the window. I cannot delete whatever is in there or change the password via the forgotten password route. Thus to sign in to KDP I have to use an alternate browser. With both Opera and Chrome I can sign in with no problems. I have added a screenshot of the KDP log in which illustrates the problem. Grateful for any solution to this irritation. Thanks, Paul

I recently logged into my laptop, which has lubuntu installed on it, for the first time in some time. I had forgotten the primary password that I set in firefox on that machine. I was confused about this and reset my Firefox account password with my recovery key. Now the primary password on my main desktop machine has changed and I am unable to use the password manager. I am afraid of losing all my saved logins and passwords. I tried resetting the primary password on the lubuntu laptop but the method in the help article did not work.

How is it possible that the primary password changed on my desktop machine? Please help, I do not want to lose all my password as I do not remember them all and some of them were automatically generated by firefox.

I have noticed that if I use File>Empty Trash with TB 102.0, the Trash folder initially appears to be empty. However, if I close Thunderbird and open it again, the messages I thought I had deleted still appear in the Trash folder. In order to empty the Trash folder, I have to open the Trash folder and delete each message to avoid this problem.

I reset my privacy settings to "standard", as they were causing too many problems. I quit Firefox. Some websites (like Google) are still telling me that cookies are disabled, when they are not and don't allow me to go to these websites. I attached 2 screen captures. Any reason for this and how to fix this problem?

Thanks.
