Very good tool, unfortunately doesn't work with TB higher than 52.9.1 (with 52.9.1 it works perfect). There is no alternative for this. minimizetotray-reanimated for example makes it possible to minimze to tray yes, but you still have to do it manually once at startup of windows.

EDIT: Now User morat from mozillazine gave me Version minimize_on_start_and_close_1.3.2.2 it works like charme with v60.4-x64
