I have a problem with scrolling in the Firefox for Android version on my Samsung Galaxy S7. Every time I scroll on a website I get gray arcs showing on the edges of the screen. These are supposed to only show up when you reach the edge of a site, so when I scroll to the very bottom of a page, the gray arc should show on the bottom for example. Now when I scroll down the arcs on the right and bottom side of the screen always show up, and when I scroll up the right and the top one shows up. Even when I'm in the middle of the page. The page is maximized so there are no left and right scrolling. This only happens when I do a scroll where I release the finger and the screen continues to move a bit by itself and then stop. If I scroll and don't lift the finger from the screen until the scrolling is stopped, the arcs don't show up. This problem started on the 59.0 version on Firefox for android, before that it was working fine on my device.
