Hi   !
May I suggest that you contact   Kaspersky support   ?

Contacted Kaspersky for solution and received a timely, efficient, and comprehensive response.

FYI for others:

When I renewed Kaspersky Total Security to 2017 version the Authority Certificate for Kaspersky did not load to Mozilla Firefox...for whatever reason.

The Certificate was merely Imported from my Kaspersky files and problem resolved.

I reviewed info provided by contributors in this forum (the same problem posted in another question) and while some suggestions identified the issue correctly, the details of the solution, step-by-step resolution actions, were lacking.

I can post those here if anyone else is interested.

Thank you so much for letting us know;   very thoughtful of you we sure appreciate it   !
