Browser Debugger (Built-in)
On Firefox 19 or later, it's possible to use the built-in JS debugger on the browser itself. Go to about:config and set the following two prefs:
- devtools.chrome.enabled: true
- devtools.debugger.remote-enabled: true
After you restart the browser, you can access the Browser Debugger through Tools > Web Developer > Browser Toolbox. (Note that before Firefox 28, this was labeled "Browser Debugger" and only the debugger was available, not the whole toolbox.)
