User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20150108202552 Steps to reproduce: 1. open the Firefox in the PC. 2. take the remote of the system from another system with Firefox open. 3. log in again to the system. 4. check Firefox, minimize, maximize and close buttons are disappeared. Actual results: not able to close firefox Expected results: it should restore it back, i think because if we take a remote of windows pc, the theme changed to basic theme. and when you logged in again themes changes back to arial theme.
Do you use a Firefox persona/theme ? (bug 1089312)
