While scanning slides and browsing at the same time I noticed the firefox ‘down’ arrow was highlighted such that when I hovered the mouse pointer over it the screen scrolled down. When I moved the pointer off, scrolling stopped but the icon remained in focus. This continued on for ages. I tried to figure out what was going on. Was this a feature I wasn’t aware of? I abandoned my search and have not been able to reconstruct it. Please tell me this is doable. The ‘up’ scroll did not activate. If it did I could move ‘up’ and ‘down’ through any web document. Wow
