Review for JavaScript Debugger by Yann(tm)
Rated 5 out of 5 stars
Awesome debugger for JavaScript! Compared to FireBug, *all* the scripts really show up. For instance, if you are using Selenium for testing, this debugger allows you to step into the injected Selenium JavaScript code when FireBug doesn't.
