Windows Vista. No, I can't change my OS. I didn't used to have this problem. Firefox downloaded a "security update" <-- it was not a spyware, virus, bug, glitch, flaw or related to any other program or operating system. I'm a systems analyst, I know it was Firefox's own security update. Here was the result: Everything on the internet now had two problems: 1) Every site is now an "Attack Site" including google.com (not results, the main page) same for ebay.com, amazon.com, etc. 2) Everything now had an infinite number of "incorrect certificates" I would like to disable delete and destroy these "security" features. I never use the machine to do anything that would ever pose a security threat. I would like to have zero security. I say this because I think it's highly unlikely that there is an actual "fix." I don't need "security" for anything. I would just like to sometimes upload files to the internet. Right now, my machine has no internet. The "feature" that firefox downloaded blocks all sites on the internet on all browsers. And no, it doesn't block the internet. I can still ping servers. The internet is working fine. It's just "attack site" and "certificate" warnings make the internet inaccessible from any browser due to an update I'm 100% certain came from the Mozilla Firefox update I just received, because I'm never had a problem before on this machine, it happened instantly after the update.
