Review for JavaScript Debugger by Marcel
Rated 2 out of 5 stars
Tragically unstable for me. Doesn't appear to be able to bind to a single firefox process. Couldn't stop it without closing my firefox processes. When I tried to stop it with firefox still open, it hung my firefox as well.
Breakpointing was good but loading pages with it enabled was very slow.
