Bug 1165599 - Restore basic external view source. r=jsantell CLOSED TREE This restores external view source after changes in bug 1025146. It does function in e10s, however the page descriptor is not used, so viewing a POST result will GET the page instead. This is the same as it was before bug 1025146. Follow ups will add usage tracking and improve e10s behavior if there is enough usage.
