Changed Gmail.com password and now Thunderbird will not login even with the new verified password. I have tried all recommendations on the internet and nothing works.

I'm trying to troubleshoot a connection error and cannot find anything about 'SSL_ERROR_INSUFFICIENT_SECURITY_ALERT'? What is this trying to tell me exactly? Is there documentation or a debugging switch to elaborate this error, or is it really necessary to dig into the source code to find out about this? Even mozilla search and google comes up empty.

I'm running 115.12.0esr on Linux. I have another Linux system running 115.7.0esr that has no problem connecting to the same URL.

Thanks!

Hey all, Before I go to far, here... Firefox version 127.0.2 (64-bit) Windows 10 Version 10.0.19045 Build 19045 Extensions - Malwarebytes browser guard.

What I've done: Cleared cache, history, etc. etc. ran multiple system scans restart app restart windows

So how do I keep Firefox from opening pop-up for about:config? That's right, There are pop ups that firefox allow to open new tabs, and its the about:config page.

Also, every time I start typing out google in the address bar auto suggest fills in googleleadservices or something like that. I already went through all the same steps above and more. I originally thought it was just opening one of the last pages I went to, but if I've "cleared" everything as per the way firefox has it set up, why would it have any history of what the last page was?

Sometime in the last few months, Firefox (Developer Edition) stopped allowing redirects and links to file://-protocol URLs. Is there a way to re-enable this for my personal browser, e.g. via about:config or the like?

Thanks!

I added a secondary email to my account last September--or so I thought. My profile currently shows only the email I log in with. When I try to add a secondary email, I am told that another user has registered this email (same response for two different emails). Note that I regularly receive email from Mozilla at the secondary email address. Why isn't this showing up in my profile?

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com 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…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

I add 2FA whenever possible. I was adding a new website yesterday and was unable to: FireFox (v. 127.0.2 on 64-bit Windows 10) was showing "Log in with Facebook" that was blocking one of the squares on the QR code! So I had to enter the many characters that were presented in order to add the 2FA code to Authy!

I looked in the settings and couldn't find anyway to turn that off.

How can this be fixed?

Thanks,

John

Hello,

When the primary password window opens and I click Cancel, can that window close AND can it prevent Thunderbird from opening?

Example: what if I bring my pc to a repair shop and they open thunderbird and click Cancel on the primary password window. They can See my previously viewed email. I do not want them to see those. Clicking Cancel AND closing Thunderbird would prevent them from seeing emails.

Could this be a future enhancement?

Thanks

Jim

The password I've been using to access my stored payment methods is suddenly not working. I've tried using my Master (sorry, Primary) password and this doesn't work either

Three times in the last few months when I was forced to do a TeleDoc visit using my health care provider's 3rd party teleconferencing software I noticed that it changed my Windows 10 sound setting from the correct Optical (Digital Audio S/PDIF) to the incorrect "USB Audio Codex". Consequently, I couldn't hear anything until I changed the sound setting back to Optical. The 3rd time the user interface had changed significantly and for the better except that the sound setting had not only changed to USB Audio Codex, but it was stuck at that setting--so the Doc called me on the phone so I could to listen to what he had to say.

I don't think this is browser dependent. The 3rd time I was using Firefox, the previous 2 I may have been using Edge. I am still very surprised, think that it's a security issue (I'm using Bit Defender), and wonder how else Windows can be tampered with?

Please let me know what you think, and what my next step should be?

I have a local web server which is misconfigured. Its my server, its on my LAN, and no data traverses any devices not under my control. I need to be able to access it via HTTPS with an expired certificate in order to FIX THE EXPIRE CERTIFICATE. How do I do it? Firefox used to have a "accept the risk and continue". Whoever took this feature aware has created a very significant problem for me and I want the capability back.

Hello, In order to log into Netflix I have to uncheck the Cookies box and Private Browsing box in Privacy and Security under Settings (I usually run with these enabled when just browsing). When I do this it asks for a Restart. Upon Restart the Netflix Login page always appears on its own. I am curious as to how Firefox is getting steered to the Netflix Login page when it is not being specifically told to go there. I assume it is somehow tied to the unchecked boxes. It's not a big deal to me but I am curious about what is going on in the background and the dynamics involved. If someone has the time to explain what is happening I would appreciate it. Thanks you !

And thanks to Mozilla in general for keeping Firefox so excellent.

How do I disable secure connections for local domains? like http://nas.local or http://nas.home.arpa ?

I search for the subject but nothing came up. Apologies if this has been asked before.

Hi.

I have several internal sites, each signed with their own internal CA/subCA. These CAs are all named the same, but have different crypto materials.

If I import just 1 CA into FF (directly or in Windows store with security.enterprise_roots.enabled ), the site with that CA works fine (browser warning is not presented), but ALL those other internal sites give this error:

An error occurred during a connection to 10.1.1.1. Peer’s certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE

with no option to add a security exception.

If I add the CA for another site, that one works as well, the others won't. If I remove all the internal CAs, all the sites start working again (with browser warning, ofc.).

I tried in Chrome and Edge and I get the option to create a security exception for the sites for which I did not install their CA, which looks like the ideal/preferrable option to me.

Is this as intended (and why?) or can it be fixed?

This looks somewhat similar to this: https://support.mozilla.org/questions/1170738

Thank you. Davide.
