Description Doran Moppert 2017-08-08 06:22:16 UTC

If a long user name is used in a username/password combination in a site URL (such as 'http://UserName:Password@sometime.org'), the resulting modal prompt will hang in a non-responsive state or crash, causing a denial of service on the browser as a whole.
