Useful prefs

These prefs may be useful for people writing Mozilla extensions. They should be added to user.js or about:config.

• Disable XUL cache (so you don't have to restart everytime you change a XUL file)

user_pref("nglayout.debug.disable_xul_cache", true);

• Enable dump() output (read more)

 user_pref("browser.dom.window.dump.enabled", true);

• Show chrome errors in the JavaScript console

user_pref("javascript.options.showInConsole", true);

• Enable strict JavaScript warnings. (Note, that since most people have it turned off, you will see dozens of warnings in their code. Use with caution).

user_pref("javascript.options.strict", true);
