Installing a fresh (never before had Firefox installed) copy of Firefox 39 on Mac OS X (verified on Mac OS X 10.7, 10.8, & 10.9) results in blank windows. After installing, I open up Firefox and see the Import wizard displayed blank (see uploaded image import.jpg). I click the red dot on that window to close it and then I get the Default behavior dialog box which displays correctly (see uploaded image default.jpg). I click to use Firefox as the default and then I get a Firefox window open up which is completely blank - no toolbar or address bar (see uploaded image windows.jpg). I then quit firefox and correctly get asked about closing 2 tabs (see uploaded image tabs.jpg). I then open firefox again and get the blank window. If I do an about, I get a blank about window (see uploaded image about.jpg). I've tried restarting and that does not resolve the issue. Repeating this as an upgrade rather than a fresh install results in some success (my Mac OS X 10.10 upgrade let me see the standard firefox window) while others show the blank windows (I tested Mca OS X 10.8 & 10.9).
