hello atung45, You could try changing one (or both) of these hidden settings: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful. (2) In the search box above the list, type or paste '''wheel''' and pause while the list is filtered (3A) Double-click the '''mousewheel.default.delta_multiplier_y''' preference and type in a higher value to make each movement of the wheel cover more ground. For example, you could try 300 or 500. You can keep this tab open and experiment with scrolling in a different tab until you find a value that gives you the speed you're looking for. (3B) Double-click the '''mousewheel.system_scroll_override_on_root_content.vertical.factor''' preference and type in a higher value. For example, try changing 200 to 500. You can keep this tab open and experiment with scrolling in a different tab until you find a value that gives you the speed you're looking for.
