You have to download actually google earth. It's not available on the standard satellite imagines you can get on google maps.
Yep, google earth pro on pc/mac. I just got it this week and it's pretty cool.
Easy to mark your spots on GEP. You can export to a folder and copy that folder into your FF. Need to download GPS Babel to do all that, but it's free too. All way easier than I would have thought.
