I am working with Firefox 35.0 I get the security certificate error message of site name) uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer).
This happens on each page that I go to. I can pull the page up with no problem with Explorer. Please Help. I don't have any security software that would be stopping or scanning SSL.

Hello insane0420, with CLOSED firefox try to delete the cert8.db in your profile folder, and check it again.
thank you
Check the date and time and time zone in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
Check out why the site is untrusted and click "Technical Details" to expand this section. If the certificate is not trusted because no issuer chain was provided (sec_error_unknown_issuer) then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
- Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
- Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
You can see more Details like intermediate certificates that are used in the Details pane.
If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
- Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
- Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.
this might also be a problem caused by malware on your pc, since you're using very outdated versions of plugins and the browser itself your system is very vulnerable. please Update Firefox to the latest release and update all your plugins as soon as possible! afterwards i'd also recommend to run a scan of your system with multiple different security tools like the free version of malwarebytes, adwcleaner and microsoft safety scanner.
www.futurescripts.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer) FF 36.0 issues this msg for selected pages, not all. IE and Chrome don't seem to have a problem with this. I have two different Win 7 desktops that get the same error.
@lionelbob, this is an issue with the site in question - they haven't properly implemented their intermediate certificates, so the chain to the trusted root certificates in the browser is incomplete. please report that to the webmasters of the site: https://www.ssllabs.com/ssltest/analyze.html?d=futurescripts.com&hideResults=on&latest

Internet browsers Microsoft Internet explorer and Google Chrome do not have this issue. And it looks like I'm not the only one with this problem. This needs to be bumped up to Firefox support.

Note that Firefox automatically stores intermediate certificates that servers send in the Certificate Manager for future usage. If a server doesn't send a full certificate chain then you won't get an untrusted error when Firefox has stored missing intermediate certificates from visiting a server in the past that has send it, but you do get an untrusted error if this intermediate certificate isn't stored yet.
