I was fooling around with the per-profile user.js file, and putting any calls to dump() in it result in this error at startup: > An error occurred reading the startup configuration file. Please > contact your administrator. > line 109: ReferenceError: dump is not defined So I guess that user.js is rather limited in what it can do. So what exactly are the limitation of what you can do with user.js? Is it only good for putting in user_pref() statements that won't get overwritten?
