title: require-less throwing lessc error in firefox
body: <p>So I'm working with RequireJS and BackboneJS. I can get everything to work fine in Chrome but when I load up in Firefox I'm getting that lessc is not defined. Obviously pulling out the less files will prevent the error from occurring. Does anyone have any ideas why require is unable to load lessc in firefox but its doing fine in chrome?</p>
