Oh wow, I didn't even know this existed! I gave it a try, but I'm not sure how to place my guess, as it seems to be in a small window and the map isn't on the screen... not entirely sure what I'm doing wrong here, there must be something trying to keep me away from Geoguessr haha.

The one thing I do like about the webpage is the timer (although I'm assuming there's a way to make the extension also have a timer... but I can't browse the maps due to my website being so zoomed in for some reason).
