So I updated my computer to Windows 10 the other day, and ever since then, firefox won't let me access youtube. It gives me the "connection untrusted" page, but doesn't give a bypass or "add certificate option". It also tends to say that Bing and Yahoo are untrusted, but lets me bypass and add exceptions for those. Does anyone know how to fix this? All I've found were old support forum threads from 2012 where people said "nvm fixed it". My computer has no parental settings, I don't have Norton, and I can access it fine in IE but not firefox. Any ideas?
