Cannot delete cookies nor cache due to a grayish button. First it works fine, after a few hours, buttons are gray.

Also sync seems not to work anymore when this happens.

When I close a private browsing session and open it again, the given permissions for cross-site cookies are still there and Google remembers my last search results from the last private session (in the suggestions below the search box)!?

I am writing to let the community know that, at least in my case, the guidance from TB 1/2024 KB article on Qauth2, [and linked Microsoft article], didn't solve the odd password behavior that began around January, 2024, between TB and my Microsoft hotmail account--which had worked perfectly with TB for maybe 10 years?

Beginning in January I typically received an error message that SMTP server login failed; please enter password. But after fixing that as per the KB article (first trying to maintain normal password, then when that wouldn't solve it, turning on 2FA, switching to Qauth2 with cookies enabled), it turned out for me that with Qauth2 and 2FA, I could send mail okay but then the Outlook.IMAP server would not connect so receiving emails stopped. Several times after this failure I tried switching back to normal password AND turn OFF 2fa in order to get Outlook.IMAP to reeive email...but then SMTP would keep requesting passwords, and every day or two i'd get a repeated request to reenter the Imap server password for receivfing also.

The only stable fix I found after weeks of livign with this and debating abandonment of TB came when I turned 2FA back on, requested an app password from my Microsoft Account, changed TB Server settings back to Normal password for SMTP and Outlook.Imap, and then entered the App password when prompted by TB for to eonnect with server for receiving and sending.

This has worked fine and apparently been stable, without new reqauests to me for passwords, for 2 days, whereas all other fixes in past couple months have not lasted longer than a day or less before TB requests again that I enter a password to connect with my hotmail account. (All through this my gmail connection via TB ahas remained flawless, thought I did get a request for a gmail app password, which I obtained and entered--just once and all has since been fine).

I don't know why several careful step by step attempts to do everything in Mozilla's Thunderbird KB and Microsoft articles suggested didn't work--for a residential Microsoft account, whether I tried to follow guideance for those experiencing SMTP problem only, or the Imap server connection generally.

My only guess about why my Win 10 desktop installation is different? I have Outlook for Android running on two or 3 different Android devices also, perhaps that complicated things?  I also used to have a mirrored account (in other words, name@hotmail.com is my main account, but I also had a 2nd "nickename" acct with the same name, set up as name@outlook. com.  

(But I removed that nicknamed acct in case it was causing any of my authentication problems; made no difference. )

When I try to access my payment preferences page on xfinity.com, the page goes blank and it appears that it is being blocked. I can't figure out how to unblock it. I had to use Microsoft Edge to access the page to change my information. Can you please assist?

I found an article how to reset the master password. It worked for Mozila's password in the browser but not with thunderbird. I cannot get it to go to thunderbird's tool to reset it from there.

Hello everyone,

I’m reaching out because I have some concerns regarding Norton’s HTTPS scanning feature. Recently, I noticed that Norton scans HTTPS traffic, and I’m unsure about how this impacts my privacy and security. While I understand the feature is meant to detect threats, I’m particularly worried because it involves decrypting sensitive information. This raises concerns about whether my personal data, such as login credentials or payment details, could be exposed during the scanning process. Has anyone else experienced issues or found this feature problematic? I'd love to hear about your experiences and whether there are any steps I can take to ensure my online security without risking privacy.

I also have found a names of site that were blocked in the report generated from Norton

someting to read ---> https://zakird.com/papers/https_interception.pdf

Thanks in advance!

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 I click Get Messages, I get a popup: "Sending of password for user myname@insight.rr.com did not succeed. Mail server mail.twc.com responded: invalid user name or password." I went into tools>options>saved password>pop-server and changed the password. I went back and clicked Get Messages and responded my pasting the password and checking use password manager to manage this password. Same result.

I have changed the privacy settings as suggested in the help guide, but any image I text to my e-mail is blocked. They can only be double clicked on the footer to open them in another application. Is it possible to have them load automatically in the body of the e-mail?

Hey I registered for sync Mozilla. After each lunch I have message windows pass code...Its really irritating me. How to leave passcode (becouse I want to protecs my passcodes manager settings ) and have turned on passcode windows just when I need pass code manager. Please fix it at next updates

I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

I am having issues with Thunderbird not retaining my email server and passwords. Each time I want to send an email, it prompts me for the password and then tells me that the email address and server don't match. I have tried numerous times to correct this, but it doesn't hold the information. It also switches the server info between accounts. I have 3 different email account and sometimes only one works correctly

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! !

After changing passwords at the email provider, it asked for and saved the passwords for the incoming server. It asked for the SMTP password for the first account and saved that (using that username) but did not ask for or save passwords for the other accounts using the same SMTP server.

So... email can be received on three accounts but can be only sent from one. Is there some way to add the passwords?

Tell me how I can continue to use thunderbird with the above account and also Denis.Clarke.hotmail.com after September 18. I have 4 individual historic E mail accounts and thunderbird joins them together. What do you need to do? To deal with threat below.

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.
