While Firefox is loading long, list-type pages, the scrollbar naturally expands in length. I was used to grabbing the scrollbar thumb, pulling it to the bottom (out of browser focus,) triggering further page-loading, and being able to repeat this by merely jiggling the mouse after each load. Since the latest release (116.0.?), my mouse loses focus on the thumb on each reload, and I have to re-click on the thumb in order to drag down to force the next reload. This has radically slowed down some of my regular web activities. Is it something that can be (re)configured on my end?
