An unpatched vulnerability in handling of JAR: protocol handler URL’s has been reported recently.

Information is available at GNUCITIZEN Blog via entry "Web Mayhem: Firefox’s JAR Protocol Issues".

Information was publicly disclosed by Petko D Petkov (aka pdp).
The issue was originally reported in Bugzilla document #369814 by Jesse Ruderman of Mozilla community.
I.e. it's worth of mentioning that Mozilla security group is aware of the vulnerability.

Shortly: the vulnerability is due to same origin and XSS issues when opening .JAR packages.
The following file formats are known attack vectors: .zip, .doc, and .odt.
Information about OpenOffice.org and MS Office via pdp's post.
