No, a simple ad blocker isn't good enough. I want to be able to rewrite scripts and CSS on the fly. I'm sick of sites doing stupid **** that makes the page unusable. Under Firefox (desktop), the three extensions NoScript+GreaseMonkey+Stylish will do this for me. Is there any way to get the same functionality on iOS using any combination of jailbreaks, tweaks, alternate browsers, alternate system files, repositories, etc?
