Uncaught ReferenceError: module is not defined(…) on some sites

[mttwc]

Hi! We use URI.js in a multi-browser extension that we are developing, and we are running into an issue on https://mochajs.org/ where URI.js tries to access modules.export when modules is undefined. This is because on this site, the exports variable is being used for something, so if (typeof exports === 'object') will return true when it shouldn't.
