WASP v0.2 released

Update 07/02/13: To avoid any confusion about the "High/Medium/Low/Hard to detect" confidence levels: this refers to the avoidance of true-negative and false-positive detection by WASP itself and is really not related to the features or security aspects of any of the listed products.
WASP is the Web Analytics Solution Profiler, a Firefox extension aimed at web analytics implementation specialists, web analysts and savvy web surfers who wants to understand how their behavior is being analyzed.


Couple of easy steps to get started:
  1. Uninstall the previous version (under Tools/Add-ons) if you have it.
  2. Download & install Firefox if you don't already have it
  3. Get FirefoxInstall the WASP extension.
  4. (if you are not prompted to install) Save the .XPI file to a temporary folder than drag it on your Firefox window. You should be prompted to install.
  5. Restart Firefox
  6. In Firefox, use View/Sidebar/WASP to display the WASP sidebar.


The first version has been downloaded nearly 200 times and I received great feedback. This version of WASP is the second beta release. It is much more stable than the previous version and now includes information about Query String and Cookies. It has been tested more extensively, but as with any beta software, you might find minor glitches here and there. Your feedback is highly valuable and appreciated!

Tip of the hat

Some credits goes to the following people for their inspiration or simply helping me out with some bugs!
  • WAVcheck, from Webbanalys, extends on the same idea with an executable version which can detect up to 27 different vendors.
  • Rahul Revo posted on his blog a request for a Greasemonkey extension that would detect Google Analytics. Mohnsish Rao proposed a simple solution.
  • Mike Keyes, on his blog "On the trail", created a simple bookmarklet (a one-liner JavaScript you can put in your favorites) that will detect a bunch of different vendors. Cool, simple and works in both Firefox and Internet Explorer.
  • Vendors sometimes provides their own debugging aids, usually in the form of a bookmarklet that will display the parameters being passed to their data warehouse.
  • Some have proposed developing Unix-based scripts with grep and wget or perl but it looks to me like a pretty complex endeavors that have its own limitations.
  • Or you could get help from your vendor or ask for a independent consultants to help you out. Maxamine is one of them.
  • Other "complementary" solutions that might help: Watchfire WebQA is particularly good at crawling a site and looking for specific code.
  • Fiddler or ieWatch are two useful tools for Internet Explorer.
  • Charles is a proxy that records every communication between your browser and the Internet and will work with both MSIE and Firefox.
  • I use a bunch of Firefox extensions to help me in my day to day Web development activities and some of the WASP features are inspired by those tools. Look for FireBug, Live HTTP Headers, View Dependencies and Web Developer and View Cookies.
  • AlertSite recently posted a Firefox extension named DejaClick. Not only is this extension wonderful as a very powerful macro recorder, but it is also one of the best packaged extension I have seen so far.
  • I found out the spirit of the early days of the Web is still alive in the specialized groups I relied upon to help me out with some development issues. Thanks to Neil & Nickolay from
