Please refer to the top-level page for more information about the purpose and the design of this tool.
Note: As of December 2011, I am no longer updating the URLs tested by this script. Since the sites have since moved to new versions of their CSS and JS scripts, this page won't work. On top of this, it looks like the Firefox detection approach is obsolete; try the Chrome version instead.
Let me know if it worked:
not at all. Your feedback helps me improve the tool.
Not sure about the results? Clear your cache and try visting some of the sites listed, then re-run the test.
