From Sept-16-2024 Microsoft will deprecate Normal Password and require OAuth2 authentication on its email accounts accessed from Thunderbird and other clients.

I'm trying to convert my hotmail accounts on Thunderbird to OAuth2 authentication.

Server Settings Authentication can be set to OAuth2 because OAuth2 is an option in that menu.

But SMTP Server Authentication cannot be set to OAuth2 because OAuth2 is not an option in that menu.

Both Connection Security methods ( Inbound and SMTP ), are set to STARTTLS.

See screenshots, thank you.

When trying to load a PFX certificate into the latest version of Firefox on a new Windows 11 computer, the certificate will load just fine but Firefox will not offer prompts for things such as mark the key as exportable or enable strong private key protection. Tried the certificates in chrome and they work just fine.

This causes strong private key protection to be enabled by default and Firefox prompts for the security certificate as it loads each stage of the login screen. You have to select the certificate at least six times before you can get to a screen where you can enter your password for the site, and then you constantly have to select the certificate for every function of the web site thereafter.

Any work around for this?

Why has my otherwise serviceable Firefox for Android suddenly begun redirecting my input of "nnnnn.com" to "https://www.nnnnn.com/sa/ar/Home.page.com" ; forcing me to edit the url to include

" ... /us/en/ ... " in order to reach the English language website? 

I occasionally research Arabic language websites and those are rarely if ever Saudi Arabian as the redirect imposes. Update: Troubleshooting I did on Firefox Android shows that my issue is only in Private Mode. Typing the affected URL in regular mode gets me to the correct US English home page with no redirect to the Arabian version.

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something fascists do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

Problem: Persistent 150 KB of Cached Web Content For several years, I have gone to “Settings” / “Privacy & Security” / “Cookies and Site Data,” clicked the Clear Data…” button, checked both “Cookies and Site Data,” and “Cached Web Content,” and clicked “Clear”, and consistently gotten BOTH “Cookies and Site Data,” and “Cached Web Content” down to “0” zero. Recently, I have been unable to “Cached Web Content” to go below “150 KB of disk space.”

         I have NOTHING listed in “Manage Cookies and Site Data” or “Exceptions -- Cookies and Site Data.”
         I have tried reinstalling, but the problem has persisted.
         On the assumption that this is malware problem, I have continued to use Mozzella VPN, but stopped using the program for browsing, etc.  Should I stop using it altogether until the problem is fixed?
         Can you tell me how to get rid of the last “150 KB” of “Cached Web Content”?

Switching to Protected Browser... COULDN'T LOAD XPCOM.!! it stopped a month ago and yet to get an answer , from you guys. It seems no one want to answer or try to find the error issue. Uninstall firefox and reinstall!!! No by doing that you will lose all of your data thats attached to firefox anywhere from you bookmark to user names and so on, Thas not a good solution AT ALL!!

Hi!

I've been having consistent trouble getting firefox to save my passwords. I'm signed in, have all the password-managing options enabled, and I import my passwords from chrome (which I've wanted to stop using) but my saved passwords tab is always empty. The next time I use firefox and I'm logged out, it's all wiped clean. When I try to synchronize my settings and passwords after importing again, nothing happens when I click Synchronize.

I've restarted the browser many times, opened it in Troubleshoot Mode (here I was able to import, save my passwords and synchronize just fine), went on to disable all my extensions one by one, themes, and hardware acceleration, but when I opened the browser normally, the problem persisted. I don't know what to do at this point!

I'd appreciate some help, thank you.

When I click on a link from thunderbird mail to a specific website, it takes me to a log in page in the specified website where the email is automatically filled in. In firefox browser, I have cleared history for all time, including "form and search history", cookies, cache, browsing and download history, active log ins, site settings, and offline website data. I have deleted my log in for the specific website (the id and password for the site in settings, password section. In Thunderbird, I also deleted, in the Privacy and Security section, all "saved passwords" When I open up the page of the specific website in question, through Thunderbird, I continue to see on the log in page, that an old email I no longer use is entered automatically. When I type in firefox browser the same specified website, the old email address does not show up. That makes me think that the log in information is stored somewhere in Thunderbird, not firefox. What is the solution to remove this information whereever it has been stored?

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!
