Thank you all so much.
I have always used map view (instead of list view) especially when I want to see the listings in a specific area of a city.
However, I just don't see the map or map view button (anymore) neither on Safari nor Firefox. Has it been hidden or moved to some not so visible spot? (the answer is yes, it is hidden depending on how you are using your browser.)
If you are using a browser with a sidebar, the map function doesn't show and there is no bottom slider to show that there is more info on the right side of the page, off the screen. So the answer is that if you have any sidebar including the narrow default one on Firefox, you need to close it - only then will you see the map function on the right side. Otherwise, I don't think there is any other way to access it.
I did see other people saying the "map function" disappeared - I do think the page layout is not so conducive to smaller screen sizes in which case the map function does indeed disappear. I think this is a bug :--)) but can be worked around.
