I have been using Seamonkey for quite some time without any issues. Recently, I wanted to start using the evernote web clipper extension, and there is no compatible version for Seamonkey. So I installed the latest version of Firefox, and it insists that the security certificate is invalid to literally every single website including even Google and Mozilla websites. I will post a screen shot of the problem here as well.

Thank you.

Here is the screen shot. This is a fresh install, so restarting, reinstalling, all that is very unlikely to work. I have had Firefox on my computer for less than thirty minutes and I have changed no settings at all. I keep my computer pretty secure with the occasional reformatting, performing all activities under a non-administrator account. It is password protected, I used avast anti-virus, and I have a paid subscription to malwarebytes. I also use noscript and adblock in seamonkey. So I do not believe that this is an issue with my computer being infected. I am very careful about that.

Oh, I am running windows 7 home edition, all current updates. Sorry, I forgot to mention that.

Check out why the site is untrusted (click "Technical Details to expand that section) and if this is caused by a missing intermediate certificate 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 (https) connections and send their own certificate instead of the website's certificate.
