Hello, any scroll down menu,c such as where the URL goes, freeks out when I click on the URL space or the down arrow to look at my history. This happens with all these types of menus. And also I frequently am unable to scroll down my screen. Even now as I am typing the curser keeps going back up to the top of the box where I started this message. I Fully scanned my computer and my computer protection didn't find any problems so I am thinking it is Firefox
