I just updated to Windows 10. Firefox now won't "minimize" or "maximize" or "close". Is it Firefox or Windows or me? What would be the best browser for Windows 10? Thanks.
According to winver.exe I'm on the latest Windows 10 as well, which at the time of typing this is version 18362.592 and I'm using Firefox. I can minimize, maximize and close the browser just fine here. If you also using Window Blinds, use another one or go to Default Theme and see if you still have problem with Firefox ? If so, uninstall and reinstall the browser ?
In my case the best browser is Firefox so can't really help you there. Although if you want something similar as to Firefox, try Waterfox Classic, or if you want more security, Tor Browser.
