‘Connection is not secure' in Firefox

ComTech14

So, whenever I try to access any website on Mozilla Firefox, I get the 'Your connection is not secure' message, but on any other browser, I can access any site just fine.

firefox version: Quantum 60.0.1 (64-Bit)

 

regards,

Probably a corruption in Firefox's certificate store. Try reinstalling Firefox.

Wrong date and time on the computer would result in SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE, not UNKNOWN_ISSUER

Either his Firefox's certificate store is borked or someone messed with his OS certificate store, making other browsers trust a phony CA and is now MITMing him with certificates signed by that phony CA.

This worked for me, but i had to manually delete some of the installation data - not all of it is removed by firefox
