(CAN-2005-0141) A bug was found in the way Mozilla displays the secure site icon. A malicious web page can use a view-source URL targetted at a secure page, while loading an insecure page, yet the secure site icon shows the previous secure state.

(CAN-2005-0143) A bug was found in the way Mozilla displays the download dialog window.
