Insecure connection error message on MAC
Can't get or send any messages in TB, just get the error message below. I read a solution to this for windows but I have a macbook pro using OS X.11.6...all help gratefully appreciated!
Secure connection failed
live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: <a id="errorCode" title="SEC_ERROR_UNKNOWN_ISSUER">SEC_ERROR_UNKNOWN_ISSUER</a>

The advice given here suggests that deleting the cert8.db file should resolve this problem. Select Help/Troubleshooting Information, click Open Folder to open the profile folder in your system's file manager, close TB, then delete the cert8.db file.
Hi, i deleted the file, removed it from trash so it was definitely not on my mac. Rebooted, the rogue file us back! Have tried several times...do you know the source of this file?
The cert8.db file will be automatically recreated in an uncorrupted form, but if you still have the problem, I wonder if you have a security or antivirus program scanning email that is interfering with the process. Do you use a program like Avast with an active Mail Shield?
Hi, no programs like avast only security i have is thru mac updates...
Do you get a dialog with the error with a view button on it? If so view the certificate. Who issues it? Who is it issued to?
Hi, not receiving any dialogue box, just the insecure connection, put in password message. When i enter the pw, which is def correct, it just keeps rejecting it...thanx for your help. Was wondering if i need to uninstall TB and reinstall?
Reinstalling TB probably won't help unless you have a very old version (latest is 52.8). Is it possible you have the wrong security settings for the mail account? Help/Troubleshooting Information, click 'Copy text to clipboard', paste into a reply here, and omit all printer and font data.
Hi, didn't delete printer / data files as not exactly sure which ones they are...hope this sheds some light on the problem? Best, Brian

Your server settings look generally OK. I found a couple of discussions related to this error. The first one involves a 3rd-party program, BrowserSafeguard, that probably is Windows-only. But the second one looks more applicable to your error message {"....additional root certificate may need to be imported..."). Open Preferences/Advanced/Certificates and follow the instructions.
Hi, I've fiddled with options in Advanced preferences, getting a message to enter password for mail server...Have entered my password...I know it's correct because it gets me into gmail...keeps being rejected...The odd email is still arriving but I can't compose / send...
For Gmail, I suggest you use imap.gmail.com on port 993 for the incoming server, SSL/TLS security, authentication = OAuth2, User name = full address. For the outgoing server, smtp.gmail.com on port 587, STARTTLS security, authentication = OAuth2, User name = full address. Set each gmail account to send through the smtp server with the user name/password for that account.
Make sure less-secure apps are allowed in your Google settings, and that cookies for google.com are not blocked in Preferences/Privacy.
