I hope someone can help, I've changed all the settings in Thunderbird for my whole family's emails (hotmail.co.uk, hotmail.com, live.co.uk) from Normal Password to OAuth2. All incoming and outgoing servers are exactly the same as Microsoft advised. None of my accounts work, neither for sending or receiving.

I removed one account and tried to re-add it (that was the advice given if the first method didn't work) but when it tries to check the password, it takes forever. I've tried to manually configure it but it wouldn't download any folders or emails. I removed it and tried to re-add it but have been unable to do even that.

My default account hasn't been able to send more than 25% of emails for a few weeks. I'm up to date with all updates and I've restarted Thunderbird and my laptop countless times.

Can anyone point me in the right direction please?

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?

Best Regards, Margaret Mackisack

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide provided to update Thunderbird, but my version of the program does not have OAuth2 as an option. My outgoing server is smtp-mail.outlook.com, but OAuth2 is not an option in the dropdown for authentication method.

Issue began Monday 7/1 where Thunderbird would not receive new email from AOL. At times it would tell me to enter the password. But the p/w I entered was not correct so that made situation worse. Found "Saved Passwords" in Help->Settings where I was able to retrieve the -correct- p/w for one of the email addresses being actively used in Thunderbird and problem solved. When I went to find the correct p/w for the other email address, the account in "Saved Logins" was not there?? Was odd that the list did display email accounts I haven't used in years, but not the 2nd one that I use daily! I tried changing the p/w at AOL Mail, but that didn't work for either of my two accounts. Bottom line, why isn't lf82me@verizon.net showing up in the "Saved Passwords" in Settings?

I need to know if this is a safe website for my identity as I've been a victimizing that and I don't need nobody knowing what I'm typing and what I'm googling so I say looking up on the Internet my phone is messed up and I'm taking it back to Cricket today because there was apps installed on my phone that I did not install the security issue and I need to know if this is legit and safe website to use to keep hackers out of my stuff.

Having followed the instructions at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d to update the security settings on my outlook/hotmail email accounts Thunderbird no longer reliably saves/enters the passwords. The password is saved in settings as that is where I copy it from to enter manually but why is Thunderbird not doing the entry as previously. It is not every log in and not always the same account, but regularly one or the other will come up with "enter your credentials" Also occasionally the credentials screen will flash on screen and then disappear, not necessarily for the account I am using at the time but one of the others. Any help appreciated Thanks Paul

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?

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.
