Protect your browser Mozilla Firefox from XSS Attacks
XSS Warning 0.3.4 protect from:
# Url attack
# Iframe attack
# Http request attack
Unsurprisingly, it warns you of potential XSS attacks on the URL string with a large blocking page. But here are some thoughts.
Firstly, it only works in the case of reflected XSS. While that’s the most common form of XSS, it’s also only one form. Secondly, because it doesn’t generate an alert box, if the XSS is loaded inside of a hidden iframe, the user would never be warned that it failed (also making it easy to check for, incidentally). I encourage everyone to check it out.
