7. Restart firefox ( quit firefox , open firefox again )
注意一下這些數值相互間的匹配
在 toolkit.zoomManager.zoomValues 中設定為 1,1.5,2,2.5,3,4,5,6,7,8,9,10
表示最大縮放比例為10倍
最小縮放比例為1倍
所以 zoom.maxPercent 要設為 1000
zoom.minPercent 要設為 100
zoom.maxPercent 設為 1000
表示最大縮放比例為1000%
1000% = 10
這樣才能和 toolkit.zoomManager.zoomValues 設定的數值相匹配
而 zoom.minPercent 設為 100
表示最小縮放比例為100%
100% = 1
這樣才能和 toolkit.zoomManager.zoomValues 設定的數值相匹配
