I wrote a little while back about a plugin for Chrome that lets you find out what WordPress theme a site is using, now I have one to find plugins! Thanks to WordPress Jedi for pointing out SpyBar for Chrome and Firefox. It helps you find out what WordPress plugins and themes a site is using.
Once you install SpyBar, you will be able to analyze websites and find each one’s theme and plugins in one click. The script did not show us every plugin for every site but it showed enough in many cases. SpyBar also shows the themes being used by your favorite sites.
