Updated Windows10 to latest version, screen and toobars turned pink. Old fixes (from 2012-14) have not worked.
Did same update on 2 other comps with no problems. Not all of all the windows turn pink--some windows are white, but all of the menu/search tab backgrounds are pink. Sometimes the window and bar pinks don't match. (I think the last 2 things have to do with the native page color, not the root cause of the problem.)

Sorry to be unclear. After updating windows, FIREFOX screen/toolbar background turned pink. After rebooting several times for other reasons, the pink mysteriously vanished. So it is fixed, but I don't know why.
