This started a couple of days ago. I was unable to save my progress in Gemcraft Chasing Shadows, playing in Firefox. It happened around the time that Firefox updated, so I suspect they broke something, but I can't tell what was broken without better understanding of how saves work here. The problem doesn't happen with Edge, so I could play using that, but.. yuk. Does anyone have any suggestions? I'd like to think it might be a single option in Firefox's About config that needs to be changed.
