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.)

Here you can get support for Firefox and Thunderbird.
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.
