The approval window opened 360 pixels wide while the page is 396, cutting off the Reject button; it now opens at 396. The browser counts the window's frame in that width, and a tall screen gives some of it to a vertical scrollbar, so once the approval's screen is up the page widens its own window by however far it would scroll sideways, times the zoom of its own tab. Firefox draws some zoom steps a little larger than it reports, so the page measures again after each widening, three times at most. The toolbar popup's window is left alone. The Firefox suite checks that the sign prompt fits at 170%. README's Visual Style line now gives the page's real width. Model: opus-5-5
