Pattern Altitude
A new symbol has popped up in the lower right hand corner of my browser window (Firefox) and I haven't a clue what it means. It is an orange square with a white dot in the lower left corner and two white parallel quarter arcs above and to the right of the dot. When I hover over it text pops up that says either "Add Live Bookmark fir this page's feed" or something like "no live bookmark available for this page". What is it and what does it do? What is a live bookmark?
