Firefox default start page UI content invokable by script
- Firefox 27
Description
Yazan Tommalieh discovered a flaw that once users haveviewed the default Firefox start page (about:home), subsequent pages theynavigate to in that same tab could use script to activate the buttons that wereon the about:home page. Most of these simply open Firefox dialogs such asSettings or History, which might alarm users. In some cases a malicious pagecould trigger session restore and cause data loss if the current tabs arereplaced by a previously stored set.
