As most of you know,in the latest Windows 10 release,you can pick the accent color for windows title bars (Pic 1). The color you choose is used by apps as the default for title bars (ex. my Opera browser in Pic 2). Mozilla does not have an option to change the title bar color,it's always silver/gray no matter what (I don't wanna use a special theme). Other browsers already implemented this as default,they change the title bar color automaticly.

My question is...will mozilla implement this feature in future versions ? (I kinda miss using mozilla and I bet I am not the only one who stoped using it because of this reason)
