摘要：
Embodiments in accordance with the invention install a primary security browser extension first in the browser event notification order list and a secondary security browser extension last in the event notification order list. On receipt of a user data event including user confidential data at the primary security browser extension, the user confidential data is obfuscated by the primary security browser extension and the user data event including the obfuscated data is released to a next browser extension in the browser event notification order list. Upon receipt of the user data event at the secondary security browser extension, the obfuscated data is restored with the original user confidential data and the user data event is released for further processing.
