Hi All I have an issue with a Mac that I just downloaded firefox on, and for most of the websites I go to, it gives me an error message: sec_error_unknown_issuer It's occurring on Google as well I can load websites that have http:// instead of https:// the mac has malwarebytes on it, and is causing no issues (i turned off the protection for it and i was still getting the same errors) I've tested it out on a PC on the same network and that's not had any issues so I know that's not the problem This is what I get on www.google.com and www.tumblr.com google.com: https://www.google.com.au/ Peer’s Certificate issuer is not recognized.
