This started happening this morning. I opened Firefox and tried going to google.com as usual but I got this error: http://i.imgur.com/XPn2xVW.png

I tried cleaning up my registry with CCleaner, refreshing Firefox, checking off 'Scan encrypted connections' in Kaspersky, but none of them worked.

My OS is Windows 7 Ultimate 64 bit.

EDIT: OK, so I followed the instructions from this link: https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER

And did what was said for Kaspersky and now google is loading on Firefox at last.

NOTE: When I tried these settings in my 2014 version, it didn't work. It only worked in the 2016 version.

thanks, if you are in a current subscription with kaspersky, you will be entitled to a free upgrade to the 2016 version of their product. please try to download the upgrade and see if this can change the issue: https://usa.kaspersky.com/downloads/software-upgrades/

Hi, I live in India so I think the US page doesn't apply to me. I'm trying to figure out how to get a free upgrade to the 2016 version. Any ideas?
