  • I use Snap Links Lite, Form Fuzzer, BuiltWith, and Smooth Gestures with your already mentioned Switch Proxy! and Edit This Cookie. Of the others you listed, XSS Rays is ok.

    • Hi Dre G, thanks for your comment. I’ve updated BuiltWith and Form Fuzzer to the list.
      (Other two that you have mentioned – Snap Links Lite/Smooth Gestures seem to enhance chrome usability rather acting as a medium for carrying out security testing).

      Thanks again and welcome to

      • Actually, Rajiv, I am sick of explaining to people about how to perform security testing.

        IMO, Snap Links Lite and Smooth Gestures are the MOST important tools for security testing that I have in my toolbox. I would probably also add CLCL and AutoHotKey to that list, but those are userland apps, not Chrome apps/extensions.
