I have OSX mavericks (10.9) on vmware. I just installed Firefox 39 on this vm, but when I launch it the browser window never renders -- all I get is a totally blank white window with the mac window size controls in the corner. I get a sinking suspicion that this might have to do with "project silk" not playing nice with vms. Is there anything you can do to help? (firefox 38 and lower versions worked fine, by the way)
