Printing Mapbox Maps?

Hi all – I’m working on a Dash app that is intended to be useful both in a print form and live online… my Mapbox map (scattermapbox with an additional geojson layer) renders great in a browser, but shows up blank on printouts.

Apparently this is a browser-specific issue for firefox ( – but I’m not sure how to implement the suggested fix on a Dash map… any ideas?
