I dual boot Win 7 & 10. Was able to sync (or FEBE?) most of the settings from the old setup (7) to the new (10). Yesterday all the add-ons on 10 were gone. I tried to sync and reinstall FEBE (I'm still having trouble understanding the difference!). Since then I get the "Your computer is not secure" message for every site I try to enter. Reinstalled, System restart, CCleaner uninstall, Safe Mode... nothing has changed it, and tring to get real Help from FF is totally lost time.

Could you click the Advanced button on that error page, then copy/paste the more technical explanation into a reply?


Generally speaking, when you get certificate errors for most secure sites, the problem usually is one of the following:

(1) Error in your system's date, time, or time zone, which throws off certificate validity checks. Sometimes allowing computers to use an internet-based time source can introduce this problem.

(2) Firefox not being set up to work with your security software that intercepts and filters secure connections. Products with this feature include Avast, BitDefender, Bullguard, ESET, and Kaspersky; AVG LinkScanner / SurfShield can cause this error on search sites.

(3) On Windows 10, Firefox not being set up to work with the parental control software Microsoft Family Safety. (To test by turning it off, see: http://windows.microsoft.com/en-us/wi.../turn-off-microsoft-family-settings)

(4) Malware on your system intercepting secure connections.

If you have any of those specific security products:

That would be the first thing to check. This support article will walk you through it: How to troubleshoot security error codes on secure websites.

If none of those ring a bell:

You could inspect a sample certificate to see whether that points to the culprit. If you want to try that now, here's how I suggest starting:

Load my test page at: https://jeffersonscher.com/res/jstest.php

You likely will get an error page. Expand the "Advanced" button and look for an Add Exception button.

Note: You don't need to complete the process of adding an exception -- I suggest not adding one until we know this isn't a malware issue -- but you can use the dialog to view the information that makes Firefox suspicious.

Click Add Exception, and the certificate exception dialog should open.

Click the View button. If View is not enabled, try the Get Certificate button first.

This should pop up the Certificate Viewer. Look at the "Issued by" section, and on the Details tab, the Certificate Hierarchy. What do you see there? I have attached a screen shot for comparison.

My Win 7 was already set the way I want it, but the new Win 10 Bitdefender still had the Screen SSL active. I still insist, that FF is typical in that it makes it very difficult for users know where to look for help, first getting through the jungle of FAQs, but I'm typically far from perfect too Thanks!!!!

There are people who try to improve this site behind the scenes. If you find a site that does it well, please point out that one as an example. I think all software companies struggle.
