when I try to open google in firefox (it is our organizations default search engine for firefox) I get this message on all domain machines:

"This Connection is Untrusted

You have asked Firefox to connect securely to www.google.com , but we can’t confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site’s identity can’t be verified.

What Should I Do?

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn’t continue.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate."

I have not tried a non-domain machine and it doesnt happen in other browsers such as opera and chrome any help would be greatly appreciated we need firefox to run certain web applications such as wix (kind of buggy in chrome never tried with opera)

Hey @bustedchromebook ,

Is your Windows updates running? At some point, Microsoft updates the root certificates and if this update doesn’t come in for some reason, I suspect this can break some https connections. If you’re running a very old OS (ie: windows xp), you could be running into SHA1/SHA2 issues. Recent browsers may be starting to give errors on old SHA1 certs.

Hope this help!
