Description Huzaifa S. Sidhpurwala 2012-07-14 12:22:52 UTC 
Bugzilla developer Frédéric Buclin reported that the "X-Frame-Options" header is ignored when the value is duplicated, for example "X-Frame-Options: SAMEORIGIN, SAMEORIGIN". This duplication occurs for unknown reasons on some websites and when it occurs results in Mozilla browsers not being protected against possible clickjacking attacks on those pages.
