I'm getting Your connection is not secure error after I updated my Firefox. I tried every possible solution deliting cert8 my antivirus not cheking https sites etc. But the thing is I'm clive in TR and my date and time settings are in US time my date format is like this MM/DD/YY where actually in TR we use DD/MM/YY so firefox reading my time directly as DD/MM/YY where is should read it MM/DD/YY. For example the date today shows as 06/09/2016 today. since firefox reads the date as DD/MM/YY it is thinking today is 6th of September. As a result I get certificate errors. Solve this!

This is not exactly how this works. Yes if the system time is off, the certs will be detected as not secure. However, the format does not effect this, the timezone settings will.

Does this happen on all browsers? I would check if it is also happening in other browsers to rule that out.

Does it happen also if you use OpenDNS? Does it happen for multiple sites? See also specific errors with these steps:

What specific certificate errors do you get?

Can you attach a screenshot?

  • use a compressed image type like PNG or JPG to save the screenshot
  • make sure you do not exceed the maximum size of 1 MB
