IP flood (IP fuck) is a addon for Chrome and Firefox, it can change user ip easily and bypass lots of websites IP checking. And that faster than proxy.
@zhedielj As far as I can tell from this picture, this addon changes header values X-FORWARDED-FOR CLIENT_IP and VIA.
you can do the same by using "Set Header" action.
I told @StephanBlackStar what the problem is in the post and i didn't get any feedback. Other users have problems as well as you can see in the thread, so the module does not work.
