Defect #533522 - This morning (NZ based) I can still trigger "Uncaught Error: Mismatched anonymous define() module: function() { return Nanobar }" by interacting with a date picker. For us putting all windows users onto latest Firefox has got them working for now. My last update from support was 12hrs~ ago saying dev team were working on as U1 priority. Side note: Seems to me Firefox is always more stable with NetSuite, considering switching company default to FF not Chrome, any strong opinions?
