ChromEdit is a user-friendly extension that allows users to edit their user profile file with ease.
One thing to note is that since ChromEdit is a basic ASCII editor, users should not expect fantastic features. For instance, there's no styling for menus to disappear when selected by their labels in non-English locales where accents are prevalent. A superior selection approach would be selection by ID; however, this approach requires DOM Inspector or XUL source knowledge.
Overall, ChromEdit is a decent extension that provides basic functionalities to edit user profile files. It is easy to use, but users shouldn't expect advanced features beyond the basics.
