I'm using W10 " Edge " browser in my lounge room with my desktop paired with a 42 inch tv display. I have my Firefox browser customised so that the scroll bars are very easy to use having applied settings found in the Noia Scrollbars extension. I also have applied " up & down " buttons on the toolbar. Both of these allow for ease of use with the mouse pointer unlike with Edge where the absence of the up & down buttons AND the scroll bars ... it seems ... being set for touch screen phones & tablets with swipe abilities. Is there a function that I can apply to adjust the width of the scroll bars in the Edge browser & are there up & down buttons that can placed on the toolbar ?
