Since a couple of weeks I'm having problems with Google (Firefox 47.0 x64), specific with the SSL certificate. Every time I'm tried to load a Google page: Gmail, Search, Plus, Maps, Wallet, PlayStore from PC, etc. Firefox throw me the error page that my connection isn't secure that cannot skipe, so I can't load any Google page. The error is: SEC_ERROR_UNKNOWN_ISSUER
This happens me only in Firefox, I already tried load a Google page from Opera and everything is Ok, no problem! The issue is in Firefox.
I would prefer post this in Firefox support forums, but... as I can investigate, Firefox is Ok and officialy, they have no problems or known issues with Google's SSL Certificate. So, looks like the problem is from my side (don't understand how?).
I need to use Google services, so: How can I disable (by brute force) the use of SSL in Google page in my Firefox?
This problem only happened to me in Google page, other pages with SSL works fine!
