Firefox / Safari compatibility ?

[AnthonyHervy]

Hi,

thank you for amazing work with pmtiles, hope this project will continue to develop, in terms of performance for vector tiles it's really very practical.

On demo website https://protomaps.github.io/PMTiles : no problem on protomaps with chrome navigator.

When I try with other navigator (Firefox and/or Safari), OPTIONS is added in header : resp status code is 206, header seems right but error when loading ressources.

Does we use other method to request if user use firefox or safari ?

@AnthonyHervy were you attempting to open https://tilesets.urbanease.io/cadastre/64/64102/64102.pmtiles in the inspector page? If so you may have been missing CORS headers for https://protomaps.github.io which would result in the red error message in browser console. That doesn't explain why it would work in Chrome though, mysterious...
