That's a browser's default behaviour when the location is requested without user interaction. In this case they request the location immediately when opening the page, they're supposed to add a "Use my location" button and in that case the browser would remember the decision for the current session.

It'd even keep happening if I click allow? (That's what I was doing, and it kept prompting over and over.)

They do have a locate button, but even clicking that didn't change the behavior.

Same. Fun sight, but pretty annoying on FF.

Yes. The restriction on the Location API are pretty strict.
