FAQ and Review

Muhindo and Salima understand some of the recommended Firefox Add-ons completely, but they find others a little more difficult to grasp. Fortunately, Assani is able to help explain some of these more complex Add-ons.

Q: Why would I want so many different add-ons to defend myself against malicious websites? If No Script protects me from potentially dangerous scripts, for example, why do I also need McAfee Site Advisor to tell me which websites are actually malicious?

A: It is often a good idea to use more than one tool to address the same general security issue. (Anti-virus programs are an important exception to this rule, since they tend to conflict with one another.) These Firefox add-ons use very different techniques to protect your browser from a variety of threats. NoScript, for example, blocks all scripts from unknown websites, but users tend to 'whitelist' the websites they visit frequently, which allows them to load potentially-malicious scripts. NoScript users also tend to allow unknown sites to load scripts, on a temporary basis, if those scripts are necessary for the page to function properly. Some of these other security-related add-ons, such as McAfee Site Advisor, can help protect you in situations like this.
