Error 403r referer is required when using local file on PC to access Openstreetmap tiles

A local file, can you attach it here? so others can try

I cannot currently supply a sample it is part of static website created by the GRAMPS family history program and is in excess of 10gB I will look at creating a single page but it will take time. I will have to use Chromium for the time being because that works as did earlier releases of Firefox I have been in touch with the Openstreetmap community and this is a known problem if however I were to host it on nginx local webserver it would work. Thanks for your response phil

tiled maps ??

lots of maps, geo maps, not ancestry maps

So you can't right click , a map, and copy to desktop etc.

The only way I can do this is by using the Chrome Browser otherwise the map is not visible due to the error message occupying the entire space would this give you the required information. The maps pin point location of buildings ie churches phil

I have used Inspect on the image in Chrome here is an overview if there is anything specific you need please let me know phil
