The following will be done in a table with notes and observations following as footnotes.
 
* - identify capabilities before diving in
* - exclude "private browsing"/privacy
 
* pop ups
* Automated Update - always checks to see if you’re running the latest version, and notifies you when a security update is available.
 
 
* Extensions
** NoScript - It allows JavaScript, Java and other executable content to run only from trusted domains of your choice, e.g. your home-banking web site, and guards the "trust boundaries" against cross-site scripting attacks (XSS)
 
* ActiveX opt-in - Disable nearly all pre-installed ActiveX controls to prevent potentially vulnerable controls from being exposed to attack. You can easily enable or disable ActiveX controls as needed through the Information Bar and the Add-on Manager. (IE)
 
* URL handling security - Redesigned URL parsing ensures consistent processing and minimizes possible exploits. The new URL handler helps centralize critical data parsing and increases data consistency throughout the application. (IE)

==== Online Protection ====
* SpyWall Anti-Spyware - IE sandbox blocks attacks encountered while browsing the web; detects and removes spyware (not free)
* 1-Click SignupShield Suite - enhanced password manager; protects against phishing fraud and automatically fills out forms; generates unlimited number of unique passwords and disposable Email addresses for signing up to Web sites. It fills sign-up forms and encrypts passwords and Email addresses for later use during sign-in. When you need to sign-in to a Web site, SignupShield automatically retrieves the correct e-mail address and password and fills in the sign-in form for you (not free)
* McAfee SiteAdvisor for IE - protects from spyware, adware, spam, viruses, browser exploits, and online scams. SiteAdvisor has safety ratings.
* Password Scrambler - automatically present unique passwords to the sites you visit, generated from a unique master password you choose. It achieves this by uniquely scrambling your password for every site you visit, so every site gets a unique, secure and hard-to-guess password, while you only remember one.
