Well Pete, you are certainly entitled to your opinion. And in regard to 
the comment about bf2 having no automation.. the fact is, it does: every 
fuzz page contains refresh code for the next, allowing the fuzzing 
process to be completely automated. BF2 needs no defense-- from its 
conception it has proved very useful. Don't like it? Trash it.

Hi Jeremy,

I think this fuzzer is useless, and doesn't have any kind of innovation.
This fuzzer acts as a cheap binary fuzzer, without any automation on 
the targeted browser, like your others fuzzers you've wrote.
There's severals DOM CSS DHTML fuzzers written in JS way more 
powerfull, did you heard about them ?

Next time  take some times before releasing such useless stuff.

    That is one point I would like to get across: fuzzing doesn't have
    to be
    and frequently isn't random, no matter how much the wikis copy its
    'definition'. The fuzzing oracle is the heart of the fuzzing process,
    and making sure it is adequate to check for bugs is, I feel, a key to
    being successful when fuzzing. I understand that near complete
    randomness can be effective as demonstrated with mangleme, etc, but I
    rarely choose that approach when working on projects; I just do not
    think of it as a huge benefit. And the number of fuzzing files is
    limited to the functions and tags and to the fuzzing oracle, all of
    which can be modified and rearranged. Information, information,
    information :)

    You did ask some good questions, thanks for your input.
