Keyloggers often target web browsers since it’s that particular interface where a lot of user authentication happens.

KeyScrambler is a Firefox add-on that scrambles your keystrokes in the kernel driver level then decrypts them at the browser level. Keyloggers often situate themselves somewhere in between these levels. With KeyScrambler, keyloggers would just record gibberish.
There’s also an IE and Flock add-on available and there’s also the Premium and Professional that offers a chock-full more goodies like support for other browsers, password manager link-ups, online poker, and MS Office support. Visit their homepage for more info.
