I did a fresh install of windows and a fresh install of firefox and in getting SEC_ERROR_UNKNOWN_ISSUER every time I try to go to google. I tried the about:config fix and that didn't work for me. it says that the site is using hsts specify that Firefox may only connect to it securely. I'm using my private home network for internet.
