I try to log in to password protected sites and nothing happens but works fine on Internet Explorer. Can't get past log in page. I even had to use Internet Explorer to login to ask this question! On the page where you enter username and password after entering and pressing "Log in" the page just stays in place. If you look at the error log you see "Warning: Unknown property 'border-radius'. Declaration dropped. Source File: https://support.mozilla.com/media/css/common-min.css?build=3fabbc0 Line: 1"
