[Virus1x]

Briefly explain your current issue(s)

Currently when I goto gmail.. the firefox addon for prevention of connecting to a bad websites says
This Connection is Untrusted

You have asked Firefox to connect securely to mail.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.

mail.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer)

Steps taken to resolve, but have been unsuccessful

nothing.

Normally it gives you a button to add exception it doesn't allow me..

Disable check of SSL-traffic or try this:

In Firefox, there is a certificate manager. (Somewhere in the settings).There you will find one or more "KasperskyAnti-VirusPersonalRootCertificate. Delete them. Important: You have to configure your computer to show you "hidden files" before.
Then import the certificate that you will find in:
C:\ProgramData\Kaspersky Lab\AVP15.0.1\Data\Cert\ (fake)Kaspersky Anti-Virus Personal Root Certificate.cer
When you import the certificate, there a three options:
trust websites - only mark -> trust websites
trust mail user
trust software vendors

Did you check the settings from KIS safe money by deactivating? Cause base on my research some users experience this issue on KIS 2015.
